Safety personnel is required. Examples of such situations include: arrival of a damaged
package of radioactive material or removal of radioactive trash from a laboratory by
Environmental Services personnel.
If assistance from the University Environmental Health and Safety office is required,
contact names and numbers are posted on the Core Facility laboratory doors. In addition,
these numbers will always be available through the USM Campus Police.
3. Response to Fire in Areas Where Radioactive Materials Are Used and/or Stored
Fires in areas where radioactive material is stored and/or used should be handled without
regard for the radioactivity in the area.
8
Once the fire is extinguished, an evaluation of radioactive contamination of the area and
any persons entering the area should be made, and decontamination performed if
necessary.
4. Loss of Radioactive Material
All radioactive material entering or leaving any USM site must be accounted for, and have
a written record maintained.
In the event that any quantity of radioactive material is lost or otherwise unaccounted for,
the Radiation Safety Officer must be immediately notified.
The RSO will initiate efforts to recover lost material, and may, if necessary utilize
personnel from the Campus Police as well as from the laboratory.
The RSO will, if appropriate, notify the chairman of the radiation safety committee, USM
administration and regulatory authorities.
3.0 Posting Requirements
1. Warning Signs
All areas in which radioactive material may be stored or used, including waste storage
areas, will be posted with the standard, “Caution – Radioactive Material” sign. An
example is shown below.
In the event there is an area in which radiation produced by electronic means is present but
no radioactive materials are present, a similar sign with the words, “Caution – Radiation
Area” shall be used.
2. Emergency numbers: The entrance to each area in which radiation may be found shall be
posted with the names and numbers of persons to contact in case of an emergency.
9
3. Notice to Employees: The standard Notice to Employees (State of Maine form HHS-845)
shall be posted conspicuously in one or more places frequented by employees.
4. Violation Notices: Notices of inspections and violations issued by the State shall be
conspicuously posted where they may be seen both by employees and by the general
public.
4.0 Radioactive Spill Procedures
The procedures given below must be followed if there is a spill of radioactive material:
1. Notify all persons in the area that a spill has occurred. Prevent all possibly contaminated
persons from leaving the area. If personnel are contaminated, refer to Procedure for
Decontamination of Personnel below.
2. Notify the Radiation Safety Officer.
a) If the magnitude of the spill is large (volume or activity), secure the area and wait
for instructions from the RSO.
b) If necessary, call the Public Safety Department (780-5211 or 911 on a campus
telephone) for assistance in securing the area.
3. For small spills or when directed by the Radiation Safety Officer:
a) Put on gloves and prevent the spread of contamination by covering the spill with
absorbent paper. Use enough paper to absorb all the liquid.
b) Place masking tape around the spill area.
c) Carefully fold the absorbent paper with the clean side out and place in a plastic
bag.
d) Wash the contaminated area with detergent. Wash the area just inside the tape first
and work toward the center. This will limit the spread of contamination.
e) Once the area is thoroughly washed, perform a wipe test on a 10 x 10 cm area (100
cm2) within the tape. Wipe this area with an alcohol swipe and place in a vial.
Place another alcohol swipe in a vial to use as a background swipe.
f) The wipe test results must be recorded in DPM/100 cm2 (disintegrations per
minute per 100 cm2). Record this value in the spill log.
g) For I-125, I-131, I-123, In-111, Co-57, Co-58 and P-32 the wipe test results must
be less than 200 DPM/100 cm2 for an unrestricted area, or less than 2000 DPM/100
cm2 for a restricted area. For all other isotopes, the wipe test results must be less
than 2000 DPM/100 cm2 for an unrestricted area, or less than 20,000 DPM/100
cm2 for a restricted area. If the measured wipe test activity exceeds the limits, the
area must undergo further decontamination and be retested. Contact the Radiation
Safety Officer if you have any questions.
h) Remove the tape and dispose of any contaminated absorbent paper, gloves, and
other material in the same manner as radioactive waste.
i) Complete a radioactive spill report form and contact the Radiation Safety Officer
(see Appendix A, Forms).
4. If necessary the Radiation Safety Officer will notify staff, USM administration and
external authorities.
10
5.0 Procedure for Decontamination of Personnel
If personnel are contaminated with radioactive material, the procedures given below must be
followed:
1. Injured Personnel: Persons who are injured as well as contaminated, and who require
immediate medical attention, should receive medical care without regard for the
contamination. The University policy for response to persons injured within the facility
should be followed. Persons caring for the injured, contaminated person should use
universal precautions to minimize the effects and spread of contamination. When the
injured person is stable, an evaluation of the contamination should be made and
decontamination efforts initiated.
2. Contaminated Skin
a) Go immediately to a sink and wash the contaminated area gently with cool water,
using a mild soap solution or a commercial cleanser such as Radiacwash. Do not
use warm or hot water since that will cause the pores in the skin to open. Wash
gently for five to ten minutes. Avoid abrasion of the skin. Abrasion of the skin
increases the difficulty of removing the radioactive material.
b) Emergency eye washes are available and can be used to flush the eyes thoroughly.
The RSO must be informed immediately if radioactive material contaminates an
individual's eyes.
c) Survey the contaminated area with Geiger Counter or NaI detector.
d) Continue washing and surveying the area until you observe background radiation
levels.
e) Record all actions taken on a Radioactive Spill Report form (see Appendix A,).
The completed form should be given to the University Environmental Health and
Safety office.
3. Contaminated Clothing
a) Any clothing that is contaminated should be removed and placed in a plastic bag.
Label this bag with your initials, the name of the radioactive material spilled, the
location of the radioactive material on the clothing, and approximately how much
radioactive material was spilled on the clothing.
b) Keep this bag in a secure location and notify University Environmental Health and
Safety office for decontamination or disposal.
6.0 Evaluation of Users and Uses of Radioactive Materials
Proposals to add new users and/or new uses of radioactive material must be submitted on
specified forms and will be evaluated by the Radiation Safety Committee and the State of Maine
Radiation Control Program. The action of the committee will be noted in the minutes, and a letter
will be sent to the State for review and approval or disapproval of the proposal. If the proposal is
denied, an explanation of the reasons for denial will be provided. If the proposal is approved, an
amendment to the license will be required. A fee for this amendment may result.
11
The following subjects will be evaluated and actions taken:
1. Types of isotopes, their activities and the forms desired.
2. Adequacy of the facilities and equipment to maintain exposures to radiation workers, other
workers and the general public below regulatory limits and ALARA principles. Included
in this area are the following:
a) Ordering procedures, inventory control, and security
b) Storage facilities
c) Procedures for handling and other operations
d) Procedures for handling radioactive waste
e) Types of instruments used for assay and survey purposes
f) Personnel monitoring
g) Bioassay instrumentation and procedures
h) Air sampling instrumentation and procedures
i) Special requirements (use of animals, etc.)
3. Previous training and experience of persons who will be responsible for the use of
material.
4. Training that will be provided to radiation workers in the areas of use and to other
personnel who may come into contact with radioactive material.
5. When a proposal is approved, a numbered permit will be issued specifying the types of
isotopes allowed; the activities; the locations of use; the approved users; any restrictions;
and the beginning and expiration dates of the permit. Permits will normally be issued for a
period of two years, renewable upon reapplication and satisfactory performance.
6. The Maine State Radiation Control Program will have the sole authority to add or
delete an Authorized User (AU).
7. Once a new user is approved by the RSC and the State, an amendment request will
be sent to the Maine State Radiation Control Program for amendment of the Limited
Scope license.
7.0 Laboratory Classification & Equipment Required
1. Laboratories are classified in accordance with the radiotoxicity and quantity of the
radioisotopes used within the laboratory.

8.0 Training for Radiation Workers
All employees who may come into contact with radioactive materials in the course of their work
will be trained in radiation safety at a level commensurate with their risk. The training will be
given upon initial employment and whenever methods or procedures change or are modified. The
type of training will vary depending on the level of exposure to employees.
14
1. General Training
All new employees receive general training concerning radioactive materials during the
orientation provided by USM. This training consists of a presentation that covers the use
of radioactive material at USM facilities, signage, hazards of radiation, and responsibility
to report any problems encountered. Employees are also given an opportunity to ask
questions at these sessions and are told how to contact the University Environmental
Health and Safety office.
2. Ancillary Employees
Ancillary employees are employees who don’t actually work with radioactive materials or
radiation producing equipment but work in the vicinity of where this type of work is
conducted. Examples of Ancillary employees are individuals who work with
environmental services, police, engineering, materials management and others who only
have occasional contact with areas where radioactive materials are used or stored.
The purpose of the training is to familiarize personnel with radiation, radioactive
materials, or radiation producing instruments, the hazards of exposure to radiation, and the
safeguards recommended to prevent or minimize exposure at this university. The
University Environmental Health and Safety office and RSO will provided this instruction.
Periodic refresher training for these groups will be conducted by the University
Environmental Health and Safety office.
3. Radiation Workers
In addition to the general training received by all employees, and the specific training
received by ancillary personnel, radiation workers receive additional training such as that
described above in more detail. Particular emphasis is placed on recognition of hazards
and methods for individual employees to protect themselves, other workers and the
general public.
Radiation workers also receive hands-on training on first employment, or whenever there
is a significant change in the laboratory protocols specific to the research being conducted.
The training is provided by the authorized user responsible or the authorized user’s
designee.
All training is documented (see Appendix A) . Documentation includes the names of
individuals receiving training, date and location of training, topics copied and signature of
trainer. Records of training are maintained by the University Environmental Health and
Safety office. The authorized user also maintains a copy of this documentation which is
available for inspection in or near the laboratory where the work takes place.
15
9.0 Safe Use of Radioactive Materials
1. Adherence to regulations
The University of Southern Maine will conduct its operations involving radioactive
materials in accordance with statements made in license applications, provisions of
licenses granted by the State of Maine and regulations promulgated by the State of Maine
and other appropriate regulatory bodies.
2. Personal radiation safety: Each person handling radioactive material shall be responsible
for conducting work in a manner that will keep radiation exposure to a minimum, for the
worker, fellow workers, patients and the general public. The radiation protection rules
given below must be followed:
a) Wear laboratory coats or other protective clothing at all times in areas where
radioactive materials are used.
b) Wear disposable gloves at all times while handling radioactive materials. While
wearing gloves, do not touch objects such as the telephone, doorknobs, etc. Gloves
should be changed when you leave the immediate local area of radioactivity.
c) All radioactive solutions and materials must be properly labeled.
d) Never pipette radioactive materials by mouth.
e) Prevent the spread of contamination by handling all radioactive materials on a
disposable, absorbent pad.
f) Do not eat, drink, smoke, or apply cosmetics in any area where radioactive
material is used or stored.
g) Do not store food, drink, or personal effects in areas where radioactive material is
used or stored.
h) Wear personal radiation monitors (PRM) at all times while in areas where
radioactive materials are used or stored. These devices should be worn as
prescribed by the Radiation Safety Officer. When not being worn to monitor
occupational exposures, PRM should be stored in the work place in a low
background area.
i) Dispose of radioactive waste only in designated, labeled, and properly shielded
receptacles. Any glassware or other object that has been in contact with
radioactive materials shall be disposed of with other radioactive waste, or
decontaminated.
j) Notify the University Environmental Health and Safety office (X 5406) if any of
the following occurs.
i. Spill of radioactive material
ii. Known or suspected external or internal over-exposure to radiation
iii. Known or suspected contamination of work areas
16
10.0 Radiation Exposure of the Fertile Woman and the Embryo/Fetus
1. Introduction
The University of Southern Maine recognizes the fact that female radiation workers who
are pregnant or who plan to become pregnant in the future are concerned about the effects
of radiation on their fetus. For this reason, it is felt that a statement of policy concerning
the duties and continued employment of such employees is advisable. The purpose of this
policy is to provide maximum protection to the fetus without placing undue burdens on
fellow employees.
2. Estimate of Risk
The National Council of Radiation Protection (NCRP) reviewed the studies and literature
concerning hazards to the fetus from radiation exposure, and published its findings as
NCRP Report #53 (Review of NCRP Radiation Dose Limit for Embryo and Fetus in
occupationally-exposed Women – March, 1977). Similar findings were reported by the
National Academy of Science and the Committee on the Biological Effects of Ionizing
Radiations (BEIR) in the 1990 Beir V Report.
The NCRP found that there is no direct evidence of increased birth defects or childhood
leukemia or other cancers at the exposure levels normally encountered in university
laboratory facilities. Some estimates may be obtained by means of extrapolation of high-
dose data, or from animal studies, but it must be realized that such extrapolations are
subject to considerable uncertainty. Using “worst-case” data obtained from several
studies, the NCRP found the following:
a) Birth Defects: The natural incidence of birth defects is about 40,000 cases per
1,000,000 pregnancies. If all 1,000,000 women were given a dose of 0.5 rem to
the fetus, an additional 10 cases would be expected (for a total of 40,010).
b) Childhood Leukemia: The natural incidence of childhood leukemia (during the
first 10 years of life) is about 1,000 cases per 1,000,000 pregnancies. If all
1,000,000 women were given a dose of 0.5 rem to the fetus, an additional 35 cases
would be expected (for a total of 1,035).
It should be emphasized that these numbers represent “worst-case” estimates, and the
actual risk is probably much less.
It should also be noted that these estimates are based on a dose of 0.5 rem to the fetus.
Because of attenuation due to the tissue between the mother’s skin and the fetus, the
surface dose required to deliver 0.5 rem to the fetus will be higher. In the case of
laboratory personnel, the surface dose would have to be on the order of 2-3 rem. The
surface dose is what is recorded by the employee’s personal dosimeter.
17
3. Current Exposure Levels
Due to improvements in radiation safety practices, the average annual dose to radiation
workers at the University of Southern Maine is expected to be well below 0.5 rem.
The NCRP recommends, and the State of Maine requires in its regulations, that the annual
whole body dose to radiation workers not exceed 5 rem. However, it is USM’s policy to
take action if the annual dose is likely to exceed one-tenth of that amount, or 0.5 rem.
The State of Maine also requires that the total dose to the embryo/fetus not exceed 0.5 rem
during the entire period of gestation from occupational exposure of a declared pregnant
woman. In addition, all efforts should be made to avoid month-to-month variation in the
dose.
4. Radiation Safety Practices
In order to keep personal exposure as low as reasonably achievable (ALARA), each
radiation worker should practice these radiation protection measures:
a) Time – Keep the time during which you are actually exposed to ionizing radiation
to a minimum.
b) Distance – Maintain the maximum distance possible between yourself and the
source of the ionizing radiation.
c) Shielding – Protect yourself with shielding when you are in a radiation area.
Remember, the shielding should be placed between the source of the radiation and
your body.
5. Declaration of Pregnancy
The policy of the University of Southern Maine regarding occupational exposure
of pregnant women is as follows:
a) A pregnant radiation worker may declare her pregnancy and estimated conception
date in writing to the RSO (See Appendix O). She should meet with the RSO to
discuss her exposure history and protective measures. This information will remain
confidential. The RSO will keep a separate record of the radiation exposure to the
pregnant employee.
b) During the gestation period, the dose to the fetus should not exceed 0.5 rem, and the
dose should not exceed 0.05 rem in any one month.
c) In order to help achieve this goal, it is mandatory for all personnel to use appropriate
protective devices and follow accepted good laboratory practices.
d) Pregnant radiation workers will not be excused from performing their normal duties
since experience indicates that occupational exposures from these procedures do not
represent any demonstrable hazard to the fetus. Conversely, pregnant radiation
workers will not be routinely assigned to non-occupationally exposed areas against
their will (for example, a forced transfer to clerical duties).
e) A pregnant employee who feels that her fetus is in jeopardy despite all the measures
taken to protect it, and despite all of the scientific information available as outlined
18
above, may resign or be considered for a leave of absence in accordance with USM
Human Resources Policies.
f) The declaration of pregnancy remains in effect until the declared pregnant woman
withdraws the declaration in writing, or is no longer pregnant.
11.0 Ordering of Radioactive Material
1. All orders for radioactive materials will only be placed by persons authorized in writing by
the RSO to do so.
2. Completion and submittal of Appendix B (Application for Authorised User – Non Human
Use of Radioactive Materials) and Appendix C (Application for Non Human Use of
Radioactive Materials) must be received and approved by the RSO and Radiation Safety
Committee prior to ordering of any radioactive materials.
3. Orders for radioactive materials to be used for in-vitro clinical or any research purposes
may only be made for purposes approved by the Radiation Safety Committee.
4. Orders will not be placed until it is verified that the activity of the received material will
not cause appropriate possession limits to be exceeded.
5. Approved orders for radioactive materials will be placed by the University Environmental
Health and Safety office following current USM purchasing policies and will be billed to
the requesting department.
12.0 Receipt of Radioactive Materials
1. Once an order is placed the University Environmental Health & Safety office will notify
the PI and Research Administration Operations Office of the details of the order and the
estimated shipping date and carrier. Research Administration will contact the carrier and
confirm the shipping and tracking information to ensure that the carrier has the correct
delivery information, details, and arrange to have staff available to receive the shipment at
the time specified by the carrier and in accordance with the order delivery specifications.
2. Packages will only be accepted during normal working hours (8:00 AM to 4:30 PM,
Monday through Friday) at the Science Building new wing loading dock designated as 70
Falmouth Street, Portland, ME 04103.
3. All packages with radioactive material warning labels shall be inspected and, if
undamaged, delivered directly to the Radioisotope Core Facility. If a trained person with
access to the Radioisotope Core Facility is not immediately available the undamaged
package will be placed in the deliveries lock box located in room 178 of the new wing of
the Science Building. Once a trained person with access to the Radioisotope Core Facility
is located, that person will retrieve the lock box key from the Radioisotope Core Facility,
retrieve the package and transport the package to the Facility. The lock box will be
surveyed each time it has been used to house a radiation labeled package, or at any time
there is suspicion that contamination may have occurred. Each survey will be properly
documented. (See Appendix G)
19
4. If at the time of delivery an inspection reveals damage to the package or if the package is
wet the package and the delivery person will be kept at the loading dock until the package
has been scanned and is shown to be safe. If the scan reveals that there is radiation present
above limits specified by law, regulation or policy, the standard radiation spill procedures
will be followed and documented (See Appendix A).
5. Once at the facility, a trained person will perform the package opening procedure and fill
out the receipt log. The following procedure should be followed:
a) Verify that the package is addressed to USM.
b) Visually inspect the package for damage (stains, crushed corners, leakage, puncture
holes, etc.). If the package is damaged do not accept it and require the courier to
remain on site until the Office of Campus Environmental Safety and Health has
been notified (x 5406). They will then supervise the handling of the damaged
package.
c) If the package is not damaged, sign for it and release the courier. Contact the
research isotope procurement coordinator within the facility to pick up the
package.
d) If questions arise or in case of an emergency, contact the University Environmental
Health and Safety office.
13.0 Opening Packages Containing Radioactive Materials
The procedures to be followed for opening packages depends on whether or not the package has
radioactive material warning labels on it.
1. For Packages With Warning Labels
a) Put on gloves to prevent hand contamination. If the package contains liquids,
place it on an absorbent pad.
b) Visually inspect the package for any sign of damage (e.g., wet or crushed). If
damage is noted, stop the procedure and notify the University Environmental
Health and Safety office.
c) Record the date, time, box or lot number, P.O. number, radionuclide, radiation
units on label, transport index on label, and your initials on the radioactive
shipment receipt report.
d) Use a survey meter to measure the exposure rate from the package at 1 meter and
at the package surface, compare these to the acceptable levels, and record the
results on the report. The action levels depend on the label. They are (in mR/hr):
White I Yellow II Yellow III
3' from package N/A 1 10
Package surface < 0.5 50 200
Empty package Background Background Background
20
e) Use an alcohol pad to wipe a 300 cm2 area on the outside of the package. Assay
the wipe with a gamma counter for a gamma-emitting isotope or a beta counter for
a beta-emitting isotope to determine if there is any removable radioactivity.
Compare the results with the acceptable levels, and record the results on the report.
The action level for all types of labeled packages is 6,600 DPM/300cm2 (22
DPM/cm2).
If either the measured exposure rates or the amount of removable contamination
exceeds acceptable levels expected, stop and notify the University Environmental
Health and Safety office. Take precautions against the potential spread of
contamination.
f) Open the package and perform the following steps:
i. Remove the packing slip.
ii. Check the user request to ensure that the material and activity received is
the material and activity that was ordered.
iii. Open the outer package following the supplier's instructions, if provided.
iv. Open the inner package and verify that the contents agree with the packing
slip.
v. Check the integrity of the source containers. Look for broken seals or vials,
loss of liquid, condensation, or discoloration of the packing material.
vi. If anything is other than expected, stop and notify the Radiation Safety
Office.
vii. Place the contents in a secure, appropriate storage area.
viii. Monitor all packing material and empty packages with a survey meter,
before discarding them. Record this exposure rate on the report.
ix. If contaminated, treat this material as radioactive waste.
x. If not contaminated, remove or obliterate any radiation labels before
discarding as normal trash.
2. For Packages Without Warning Labels
Open the package and perform the following steps:
a) Remove the packing slip.
b) Check the user request to ensure that the material and activity received is
the material and activity that was ordered.
c) Open the outer package following the supplier's instructions, if provided.
d) Open the inner package and verify that the contents agree with packing slip.
e) Check the integrity of the source containers. Look for broken seals or vials,
loss of liquid, condensation, or discoloration of the packing material.
f) If anything is other than expected, stop and notify the Radiation Safety
Office.
g) Place the contents in a secure, appropriate storage area.
h) If contamination is suspected, perform a wipe test on the outer package. If
acceptable levels are exceeded, notify the radiation safety office. Take
precautions against the potential spread of contamination.

23
Note: The Xray emitting Faxitron and Thermo Niton shall be inspected by a State
approved “Qualified Expert” every two years. The Spectro-Ametek instrument is
“exempted”.
16.0 Tracking of Radioactive Materials
1. All radioactive material received at any USM facility will be tracked from receipt, through
use to final disposal.
2. Radioactive material will be initially logged in on an appropriate receipt form. In
addition, a radioisotope tracking record will be initiated which lists the amount of material
that is used in each laboratory.
3. The tracking record will also list any material classified as waste, and will include final
disposition of the waste.
4. Waste stream records, including waste service contractor records, will be maintained by
the University Environmental Health and Safety office.
17.0 Inventory of Radioactive Material
1. Routine inventories of all sources are performed at all USM facilities.
2. These inventories are performed by the RSO and reviewed by the RSC, and are examined
for compliance with appropriate possession limits. A record of total activity on hand at
the time of the inventory will be recorded. (See appendix I)
18.0 Waste and Transfer of Radioactive Material
1. Categories of Waste: All waste containing radioactive material, at any level, must be
disposed of in accordance with applicable City, State and Federal regulations. As a
general rule, radioactive waste falls into one of several categories depending on the half-
life of the radioactive material and its activity:
a) Short Half-life Material
Radioactive waste containing short half-life material is usually handled by placing
the waste in storage, allowing it to decay to background, and then disposing of the
remaining waste without regard for the formerly radioactive material. If, after
decay of the radioactive component, the remaining waste is chemically and/or
biologically hazardous, it must be handled appropriately. Otherwise, it may be
disposed of as normal trash. In some cases, short half-life waste may be returned to
suppliers of such material. Examples of short half-life material are Iodine-125,
Iodine-131 P-32, etc.), and associated instruments, containers and protective
clothing and coverings.
24
b) Medium and Long Half-life Material
Radioactive waste containing long half-life material in encapsulated sources is
usually handled by return to the manufacturer. Examples of such waste include
calibration sources (Cesium-137, Cobalt-57 and I-129). Un-encapsulated sources
(Tritium, Iodine-125, Carbon-14, Sulfur-35, etc.) may be stored for decay to
background, stored for eventual shipment to a disposal site, or stored for disposal
by other means. The choice of a method to use will depend primarily on the type
and activity of the waste, and must be approved by the Radiation Safety Officer.
2. Approval of Waste Disposal: All disposal or transfer of radioactive material must be
approved by the RSO. Blanket approval may be given for well-established methods of
disposal. Each area using radioactive material must adhere to the written procedures
specific to its use.
3. A waste Log will be maintained by the RSO describing the date the waste was generated,
the approximate amount of radioactive material in mg or uci, the department that
generated the waste, and the date the waste was disposed of either through a licensed
broker or through the sanitary sewer as described in the text below.
4. C14 contaminated liquid waste can be disposed of through the sanitary sewer provided the
liquid is biodegradable and the amount of isotope is below release limits established
according to USNRC Part 20 Appendix B. The current limit is 3 x 10-4 uci/ml.
5. Disposal of compounds containing uranium such as Uranyl Acetate & Uranium Trioxide
can be made into the santitary sewer based on the following regulatory guidelines:
a. Regulations of the State of Maine (which are modeled after the U.S. Nuclear
Regulatory Commission) provide that, "Any person is exempt from this part to the
extent that such person receives, possesses, uses, owns or transfers source material
in any chemical mixture, compound, solution, or alloy in which the source material
is by weight less than 1/20 of 1 percent (0.05 %) of the mixture, compound, solution
or alloy." [10-144A CMR 220. C.2.A]. The "part" referred to is the section on
licensing of radioactive material.
Source material is defined as uranium or thorium or any combination thereof,
in any physical or chemical form. [10-144A CMR 220.A.2].
In essence, these regulations state that USM can transfer or dispose of and
anyone else can receive, possess and dispose of uranium waste without regard
for its radioactive content as long as the concentration of uranium is less than
0.05% by weight.
As an example, the typical mass of uranium used for experiments in the AMS
Labs are 215 mg. If all this material is diluted by 500 ml (500 g) of water, the
resultant concentration is 0.00043, or 0.043% by weigh.
Note: Information was obtained from Joe Blinick (Qualified Expert) letter
dated 9/28/2004. Information confirmed still valid in email dated 2/11/2014
from Mr. Blinick.
25
6. General information: Sharps, including pipette tips, shall be placed in appropriately marked sharps
containers. Waste must be segregated by isotope. Waste shall initially be placed in dedicated containers
in the radioisotope core facility. The appropriate log must be filled out each time material is placed in a
waste container. When the container is full, it will be transferred to the radioactive waste storage room
(Science 61B). Determination of which waste is decayed to background and which waste is transferred
via a licensed broker to an approved radioactive waste facility, will be made by the RSO with the
approval of the RSC.
7. Records: Complete records of disposal or transfer of radioactive material must be maintained and
available for review by the RSO. Such records must include the isotope, activity, disposal date and the
initials of the person preparing the waste. (See appendix J)
8. Transfer of Radioactive Material: Radioactive material may be transferred between different locations
that are part of the same facility license. If transfer takes place between physically different locations,
all requirements of the Department of Transportation (DOT) must be met, including labeling of
containers and vehicles. Transfer to other licensees may be accomplished if there is mutual agreement
between the licensees and the receiving licensee is authorized to use the type and activity of the
radioactive materials to be transferred.
19.0 Personnel Monitoring – Dosimetry Use
1. Criteria for Inclusion: All employees of USM who are likely to receive on an annual basis from external
sources an exposure in excess of 10% of the maximum permissible dose limits, shall be required to wear
a whole body dosimeter to record exposure. The maximum permissible annual dose limits are:
Area Annual Effective Dose Equivalent
Whole body 5 Rem (50 mSv)
Lens of eye 15 Rem (150 mSv)
Skin or extremity 50 Rem (500 mSv)
Any other organ 50 Rem (500 mSv)
2. The maximum permissible dose for a minor employee is 1/10 the values listed above.
3. Furthermore, a declared pregnant employee will be monitored to assure that the dose to the embryo/fetus
does not exceed 0.5 Rem (5 mSv).
4. In addition, any area where an adult employee is likely to receive an intake greater than ten percent of
the applicable Annual Limit on Intake (ALI), or where minors or pregnant women are likely to receive a
committed effective dose equivalent greater than 0.05 Rem (0.5 mSv) will be monitored to ensure
compliance with these limits.
5. When appropriate, the RSO may authorize monitoring of other individuals and/or groups of workers.
26
20.0 Information for Personnel Wearing Personal Dosimeters
Should the RSO determine that an employee may be exposed to radiation levels in excess of 10% of
annual dose limits described in Section 19, a whole body dosimeter will issued at no cost to the
employee of the University of Southern Maine.
The personal dosimeter consists of two parts: the radiosensitive material and filters encased in plastic,
and a plastic clip-on holder.
The following rules must be followed to insure accurate and timely measurement of your occupational
radiation exposure:
1. Wear the dosimeter on an anterior pocket or collar with your name facing away from your body.
2. If using a lead apron, wear the dosimeter outside the apron. This is required by State of Maine
regulations.
3. When not wearing your dosimeter, store it in a place where it is not near any sources of radiation.
4. Never wear the dosimeter when you are a patient and a medial x-ray exam is performed on you. The
dosimeter is used to measure occupational radiation exposure.
5. Never intentionally exposure your dosimeter by placing it near a source of radiation. Exposing your
dosimeter “just to see what happens” will result in an invalid measurement of your occupational
radiation exposure. An investigation will be conducted by the RSO.
6. Your dosimeter will be exchanged prior to the first day of each calendar quarter with a new devise. A
representative from the EH&S office will exchange the new dosimeter for the devise used in the
previous quarter. It is imperative that the quarterly exchange occurs and that the “old” dosimeters are
returned to the vendor for analysis and reporting.
7. Please note: Individuals who make the dosimeter exchange process challenging, or frequently lose
dosimeters, can be restricted from future activity involving radioactive materials if the RSC deems this
action necessary.
8. If you lose your dosimeter, promptly contact the University Environmental Health & Safety office
(x5406). A new dosimeter will be issued to you. (See appendix K)
9. After the dosimeters are collected each quarter, they are sent for processing to the vendor (Landauer). A
report of the radiation exposure received by each individual is sent to the RSO at USM. The RSO promptly
reviews the report and posts a copy so that you can also review your readings. Copies of all reports are kept
on file in the University Environmental Health & Safety office.
10. The Maximum Permissible Dose (MPD) to the whole body allowed by the State of Maine for
occupationally exposed workers is 5000 millirem per year. The eyes, skin, extremities and other organs are
allowed higher doses. However, investigational levels for occupational radiation exposure at USM are set
at 1/10 and 3/10 the MPD and are given below.
27
11. Based on exposure records for the previous five years, advise from Wayne Malloch from the State
of Maine Radiation Control Program, and a unanimous vote from the The Radiation Safety
Committee, it was decided on 6/20/2012, that dosimetry use could be safely suspended. Should use
of more energetic isotopes be proposed in the future, resumption of dosimeter use could result
based on potential exposures and RSO / Radition Safety Committee actions.
Investigational Levels
(mrem per calendar quarter)
Level I Level II
1. Whole body (total
effective; dose
equivalent)
125
375
2. Lens of eye 375 1125
3. Skin; extremity; organs

1250
3750
Please remember that you are responsible for using your dosimeter correctly. The accuracy of the
exposure measurements depends on proper use of the dosimeter.
If you have any questions concerning personal dosimeters or radiation safety, please contact the
Radiation Safety Officer at 780-5406.
21.0 Radiation Safety Surveys
Surveys utilizing a survey instrument appropriate to the energy and allowable radiation levels must be
conducted in all areas on a routine basis and whenever contamination is suspected.
The frequency of surveys depends on the classification of the laboratory (see previous section,
“Laboratory Classification”).
1. Work areas in Type A laboratories must be surveyed each day of use.
2. Work areas in Type B laboratories must be surveyed weekly.
3. Work areas in Type C laboratories must be surveyed monthly.
4. Any area that is used by more than one research group must be surveyed before and after use by any
individual or research group.
5. The package receipt area must be surveyed after any package is opened.
6. The action level for any controlled area is 0.5 mR/hr. For uncontrolled areas, the level is 0.05 mR/hr.
7. All Surveys must be documented. (See appendix L)
28
22.0 Wipe and Leak Tests
Wipe tests of areas that may be contaminated with radioactive material and leak tests of sealed sources
must be assayed on instruments appropriate to the energy and allowable radiation levels. Tests must be
performed on a routine basis, as described below, and whenever contamination is suspected.
The frequency of surveys depends on the classification of the laboratory:
1. Work areas in Type A laboratories must be wipe tested daily.
2. Work areas in Type B laboratories must be wipe tested weekly.
3. Work areas in Type C laboratories must be wipe tested monthly or upon completion of work with an
isotope.
4. Any area that is used by more than one research group must be wipe tested before and after use by any
individual or research group.
5. The package receipt area must be wipe tested after any package is opened. (See appendix M)
a. All wipe test results must be documented.
b. Action levels depend on the radiotoxicity of the radionuclide. They are (in DPM/100 cm2):
RADIOTOXICITY
Action Levels – Decontaminate if wipe level meets or exceeds theses DPM limits
Very High High Moderate Low
Restricted areas 200 2000 2000 20,000
Unrestricted
areas
20 200 200 2000
23.0 Bioassays
Bioassays will be performed on all personnel who handle un-encapsulated sources of tritium (H-3), I-
125 or I-131 above specified amounts to assure that the amount of material retained by the body is
below acceptable limits. (See appendix N)
1. Tritium (H-3): Any individual who handles more than 10 mCi of tritium in a single day in unsealed,
dispersible or volatile forms will receive a bioassay. The assay must be conducted within the calendar
month in which the material was used. A liquid scintillation counter will be used to assay urine samples
provided by the employee. Any results greater than 4 uCi/l or urine must be reported immediately to the
RSO.
2. I-125 or I-131: Any individual who handles more than 1 mCi of either I-125 or I-131 in a single day in
an open room or bench, or who handles more than 10 mCi in a single day in an adequately designed
fume hood must receive a bioassay. Persons handling solid forms or sealed sources are exempt from
29
this requirement. For I-125, the assay must be conducted between 24 and 96 hrs after the material is
handled. For I-131, the assay must be conducted within 3 days after handling. The assay will be
conducted by measuring the thyroid burden in-vivo.
A scintillation detector appropriately set for the isotope in question will be used. Any results greater
than 0.12 uCi of I-125, or 0.04 uCi of I-131 must be reported to the RSO immediately. Any results in
excess of 0.5 uCi for I-125 or 0.24 uCi for I-131 will require therapeutic counter-measures.
24.0 Procedure for use of Survey Meters
All the survey meters are battery operated portable radiation detection instruments. A Geiger-Muller probe
is attached to each unit with a cable. The steps given below should be followed when making a radiation
survey:
1. Inspect the instrument for mechanical defects such as a broken dial, loose knob, or frayed cable.
2. BATTERY CHECK: Turn the range switch to "BAT". The meter needle should deflect to the "BAT.
TEST" portion of the meter scale. Contact the University Environmental Health and Safety office if the
needle does not deflect to the correct region. This may be an indication that new batteries are needed.
3. BACKGROUND MEASUREMENT: Be sure that you are in an area where only natural background
radiation is present. Turn the range switch to X0.1. Remove the probe from its holder, and hold it as far
away as possible from the check source. Read the appropriate scale on the meter and multiply the reading
by 0.1 to determine the exposure rate in mR/hr.
4. CHECK SOURCE TEST: Turn the range switch to the appropriate setting. A check source is attached to
the side of the meter. Lift the cover of the check source box, exposing the surface of the source. Remove
the probe from its holder and place the probe face directly against the check source box, making sure it is
centered. Read the meter and compare the reading with the expected value listed on the calibration sticker
on the side of the instrument. The reading on the meter and the expected value should agree to within +/-
5%. If the reading is not within this tolerance, check to see that the probe face is centered to the check
source, and that the correct range has been chosen. If the problem persists, contact the University
Environmental Health and Safety office.
5. AUDIO TEST: While the probe is still next to the check source, turn the audio switch on and check that
it functions. The audio switch may be turned off if its use to not desired.
6. MEASUREMENTS: Turn the range switch to X0.1. Remove the probe from its holder and hold the
probe face 1 cm away from the surface to be surveyed. Move the probe slowly over the entire surface
that is being surveyed. Read the appropriate scale on the meter and multiply the reading by 0.1, to
determine the exposure rate in mR/hr. (If the needle is off-scale, turn the range switch to X1 or X10 and
survey the area.)
7. When all surveys are completed and recorded, turn the audio switch and the range switch to their "OFF
positions.
a. This survey meter has a calibration label which states the date its next calibration is due. Contact
the University Environmental Health and Safety office approximately one month prior to this due
date to arrange for calibration and batter replacement.
b. Calibration is performed annually, as required by USM’s Broad Scope Materials License.
30
c. The procedure for use of the BETA COUNTER is posted with the instrument in the laboratory.
25.0 As Low As Reasonably Achievable (ALARA) Policy
The management of USM is committed to the program described herein for keeping individual and
collective doses as low as reasonably achievable (ALARA). In accord with this commitment, we hereby
describe an administrative organization for radiation safety and will develop the necessary written
policies, procedures and instructions to foster the ALARA concept within USM.
1. The Management Representative will report the status of the radiation safety program, including
ALARA considerations to senior management annually. This will include reviews of operating
procedures as well as past dose records, inspections, etc. and consultations with outside consultants.
2. Modifications to operating and maintenance procedures and to equipment and facilities will be made if
they reduce exposures unless the cost, in our judgment, is considered to be unjustified. We will be able
to demonstrate, if necessary, improvements have been sought, that modifications have been considered
and that they have been implemented when reasonable. If modifications have been proposed but not
implemented, we will be prepared to describe the reasons for not implementing them.
3. In addition to maintaining doses to individuals as far below the limits as is reasonably achievable, the
sum of the doses received by all exposed individuals will also be maintained at the lowest practicable
level.
4. We will establish the investigational levels listed below in Tables A and B. The RSO will perform a
quarterly review of occupational exposures, with particular attention to instances in which the
investigational levels are exceeded. The principle purposes of this review are to assess trends in
occupational exposure as an index of the ALARA program, and to decide if action is warranted when
investigational levels are exceeded.
5. The RSO will also perform monthy radiation surveys.
6. The Radiation Safety Committee will audit the RSO activities at least annually.
TABLE A
INVESTIGATIONAL LEVELS - GENERAL
AREA MPD INVESTIGATIONAL LEVELS
(mrem/year) I (mrem/qtr) II (mrem/qtr)
Whole Body (Deep) 5,000 125 375
Eye 15,000 375 1125
Skin and Extremities
(Shallow)
50,000 1250 3750
7. The RSO will schedule briefings and educational sessions to inform workers of ALARA program
efforts.
31
8. The RSO will ensure that authorized users, workers and ancillary personnel who may be exposed to
radiation will be instructed in the ALARA philosophy and informed that management and the RSO are
committed to implementing the ALARA concept.
9. Radiation workers will be given an opportunity to participate in formulating the procedures they will be
required to follow. The RSO will keep in close contact with users and workers and will receive and
evaluate suggestions of individual workers concerning ALARA.
10. Results of personnel monitoring will be compared to the investigational levels established in Tables A
above.
a) If an individual’s dose is less than Investigational Level I, no action will be taken.
b) If an individual’s dose is higher than Investigational Level I, but less than Investigational Level
II, the RSO will compare the dose to that of other workers in the same category, and will
investigate possible causes and corrective actions for the higher level.
c) If an individual’s dose is higher than Investigational Level II, the RSO will investigate in a
timely manner the cause of the reading and will take corrective action.
d) In cases where a worker's or group of workers' doses need to exceed an investigational level, a
new, higher investigational level may be established, provided it is consistent with good ALARA
practices. Justification for establishment of a new level will be documented.
26.0 Audits
1. Radiation Safety Officer (RSO): The RSO will perform audits at least biannually to insure compliance
with all applicable policies, procedures and regulations. Additional special audits may be performed
when circumstances require them. Inspections may be unannounced. Facilities will be inspected at a
level consistent with the risk of the operations. At a minimum, the following areas will be examined:
a) Review of inventory.
b) Review of user surveys.
c) Review of handling of waste.
d) Review of safety procedures and policies.
e) Evaluation of user and technician.

X-ray Safety Information
X-RAY CONCERNS AND PRECAUTIONS
There are several properties of X rays that make this type of radiation particularly dangerous to use in
the laboratory. X-Ray radiation cannot be sensed by humans, but some people can feel the presence of a kind of
"tingling sensation" which arises from charged air particles produced by the interaction of the ionizing X rays
with air. X-Ray radiation is also hazardous because it can appear to "bounce" off surfaces and to "bend" around
corners. This makes it important to survey each instrument for leaks after any modifications to the instrument.
At the University of Southern Maine, these checks are conducted by the campus Radiation Safety Officer.
Although X-ray instruments have the potential to be dangerous, when used improperly, modern diffraction X-
ray instruments pose few risks to careful users. The manufacture and use of analytical X-ray instruments is
regulated by both the federal and state governments. Current regulations require a variety of safety devices
be built into X-ray instruments that make it very difficult for anyone to even accidentally expose themselves to
the dangerous incident X-ray beam. The design of the instruments limits even accidental exposures to the hands,
arms and facial areas. Also, the types of radiation used in diffraction instruments (primarily Mo, Cu, and Kα
radiation) are considered "soft" radiation. These types of soft radiation generally will not penetrate more than 2-
4 cm into the body.
Possible Health Effects
To date there have been few accidental exposures in X-ray diffraction labs, and the physical ailments from these
accidents have been relatively minor. Because of the soft nature of radiation used in a diffraction lab, accidental
exposure to X-ray radiation will usually cause damage only to the skin and possibly bones near the surface of
the body. Depending on the nature and extent of exposure some or all of the following medical problems may
ensue.
Often at the time of exposure, little or no pain is felt. However, 1-3 hours later, a first- degree burn forms on the
skin and a dull pain settles in all exposed tissues. Sometimes this is followed by swelling that turns into blisters
that finally open and do not seem to heal over. In extreme cases, skin grafts and/or amputation are required.
Exposure of soft X rays to the eyes may cause permanent cataracts to form. Because of the possibility of
cataracts forming, it is recommended that glasses be worn in an X-ray diffraction lab whenever instruments are
modified or aligned.
As with all types of ionizing radiation, X Rays cause the most damage to rapidly growing,
undifferentiated cells. Thus, women that are pregnant or suspect that they are pregnant, should take special
care to protect their fetus, especially during the first trimester. Women that are pregnant or suspect that
they are pregnant and wish to avoid exposure should contact the lab director in order to make arrangements to
get data collected by someone else during the course of their pregnancy.
45
Electrical Hazard
Another serious hazard from an X-ray diffraction instrument is electrical shock. The X- ray generator is a highly
regulated DC power supply that operates at applied voltages of 40 to 60 kV in order to achieve an optimum flux
of X rays. Also, the power supply that feeds the detector operates at about 1 kV. These power supplies should
only be serviced by trained electrical engineers. Also note that the X-ray generator has several large capacitors.
Even when the instrument is turned off, these capacitors store sufficient power to injure and possibly kill a
person. All work on any X-ray generator should be done only by personnel trained in high-voltage electronics.
Safety Procedures
1. All users of x-ray producing equipment must first become "authorized users" by completing the
requirements of the USM Radiation Safety Program. They must also read the safety information above
and agree to abide by the following rules.
2. No unauthorized personnel may defeat or override any safety features on the X- ray generators, the
safety enclosures, or the goniometers including the collimators, tube shields and shutters.
a) No user may employ any power or hand tool on any part of the goniometer, detector, or low
temperature device without express instructions from the lab director. The single exception to
this rule involves the use of specific wrenches to adjust the position of the sample on the
goniometer head and to adjust the position of the video camera to view the sample.
b) All actual or suspected X-ray exposures of any person should be handled in the following
manner.
3. Medical emergencies must be treated according to the Workers Compensation Program
requirements. Call 911 for emergency transport.
4. If the exposure was due to a malfunction of the instrument, depress the red "X-RAY OFF” button on the
either side of the generator before leaving the lab. If time permits tape a message to the front of the
instrument noting "INSTRUMENT PROBLEM" and include your name, the date and your telephone
number.
5. Report the incident to the University of Southern Maine Radiation Safety Officer at 780-5406 and to the
X-ray device owner. If medical treatment is required, notify the chairman of your department.
Small electrical fires may be put out by using fire extinguishers located in the lab.
Larger fires and medical emergencies should be handled as described in your department's safety meetings. In
the case of large room fires or major water leaks, be sure to turn off the X rays by pressing the red "X-RAY
OFF" button on the front of all X-ray generators. Be sure to contact the lab director for any lab-related
problems.
