Figure 1 - Model 2210 TLD Irradiator Showing Drawer and Disk

1.0 Introduction

1.1 Description

The Model 2210 TLD Irradiator uses a

rotating disk to irradiate a number of

thermoluminescent (TL) elementssimultaneously in the form of chips, rods,

micro-cubes, disks, and cards. The unit is

portable and designed for benchtop mounting

(Figure 1).

The Model 2210 is available in two

strengths, distinguishable on the label on the

back (Figure 2). The units made in Germany

have a 33 MBq (0.9 mCi) 90Sr/90Y source, and

those made in the United States have a 18

MBq (0.5 mCi) 90Sr/90Y source. All units

produced in Germany are calibrated beforedelivery and are supplied with a Certificate of

Calibration. Calibration is available as an

option on units produced in the U.S.

The TL samples are placed in the recesses

on the periphery of a disk. As the disk rotates,

the samples move into and out of the

irradiation beam. The number of revolutions

is pre-set by the operator. The Model 2210

Irradiator will accept disks from Models

2000D and 5500 Readers in a variety of

configurations.The front panel includes status lights for

Power and Shutter, a Start Button, a Drawer

with a rotating Drive Platter for the sample

Disk, and a revolutions setting/counting

mechanism with a display panel. The rear

panel (Figure 2) includes an On/Off Switch,

power cord receptacle, Voltage Selection

switch, fuse panel and cooling fan.

CAUTION: This irradiator contains a

radioactive source! Do not attempt todetach, move, repair or service any

component of the irradiator assembly. If

service is needed, contact Thermo Electron

Corporation RM&P.

1.2 Indicators and Controls

Power SwitchLocated on the back of the Irradiator, this

switch controls the power to all functions

except the counter.

Power Light

This front panel light is green when there

is power available at the power input panel

and the Power Switch is turned on.

Shutter Light

This front panel may be green, orange, or off. If it is green, the Platter is in the zero

position, the source shutter is closed, and the

Irradiator is ready to begin a new cycle.

If the Power Light is on and the Shutter

Light is off, the Platter is not in the zero

position (that is, the drive pin is not opposite

the proximity sensor). You should not start

irradiating under these conditions as not all

dosimeter positions will get the same

exposure. Before starting an irradiation,

remove the Disk, set the counter to onerevolution, and press the Start Button. The

Platter will rotate to the zero position and

stop. You may then insert the Disk and start

irradiating.

The Shutter Light will turn an orange

color when the Shutter is open. In a normal

irradiation cycle, when you press the Start

Button, the Shutter opens, the Platter starts to

rotate, and the Shutter Light turns to orange.

When the pre-set number of rotations has been

completed, the Shutter will close, the Platter will stop rotating, the Shutter Light will turn

green, and the sounder will be activated.

If the Power Light is off, this light will be

off.

Counter PanelThis panel consists of a small electrolu-

minescent screen and an array of buttons. Thescreen displays a large (8 mm) number that

shows the number of revolutions that have been completed in the current cycle. Belowthat number is a small (3 mm) number thatshows the number of revolutions yet to becompleted for the desired exposure. The largenumber increments as the Platter turns; whenthe upper number is equal to the lower number, the cycle is complete.

There are two rows of buttons at the bottom of the panel. The upper row consistsof six buttons, each representing one of the sixdigits in the number of revolutions to whichthe counter can be set. Pressing one of these buttons will increase the corres-ponding digit by one number. Pressing the leftmost button,for example, would set the Irradiator for 100,000 revolutions.

The left button in the bottom row is theReset Button. This is used to reset the largenumber to 0. It is also used at the end of thecycle to turn off the sounder. If it is pressedduring an irradiation cycle, it will set the largenumber to 0, which will begin the irradiation

cycle over again.The two right buttons in the lower row

are locked in position and not functional inthis application.

Sample DrawerThe disk containing the dosimeters to be

irradiated is placed in this drawer on the DrivePlatter with the drive notch in the disk placedover the drive pin on the Platter. There is asafety interlock so that an Irradiation cyclecannot be started with the Drawer open.

Similarly, if the Drawer is opened during anIrradiation Cycle, the Platter will stop rotatingand the Shutter will close. When the Drawer is subsequently closed, you must press theStart Button to restart irradiation. The counter will continue from where it was stopped.

3.0 Operation

If your Model 2210 Irradiator was

delivered in an uncalibrated condition, you

may wish to calibrate it according as

described in Section 4.0 Calibration before proceeding with the following instructions.

This section assumes that you are using a

calibrated Irradiator.

The procedure for irradiating a set of

dosimeters to a known exposure is as follows:

1. Divide the desired exposure by the

exposure per revolution to get the

required number of revolutions.

2. Set the desired number of revolutions onthe counter by pressing the small buttons

under each of the six digits. As you press

a button, the number in the corresponding

position will increment by 1.

3a. Chips: Place the samples to be irradiated

in the holes around the periphery of the

disk. Place no more than one TL element

in each hole. It is not necessary to fill all

the holes nor is it necessary that the

occupied holes be adjacent to each other.

NOTE: Handle TL elements only with

mechanical or vacuum tweezers; do not

touch them with your fingers. The use of

vacuum tweezers is recommended in

order to reduce the risk of damage to TL

elements.

3b. Cards: Place the cards to be irradiated in

the recesses around the periphery of the

disk. Place no more than one TL Card ineach recess. It is not necessary to fill all

the recesses nor is it necessary that the

occupied recesses be adjacent to each

other.

4. Pull the drawer open and insert the disk,

being careful to align the center hole on

the spindle and to place the drive pin on

the Platter in the notch on the outer rim of

the disk (Figure 4). Close the drawer.

5. Press the Start Button. The yellow

Shutter Light should come on

immediately and stay on until the

irradiation is completed. As the Platter

rotates, the upper row of numbers will

increment, showing the number of

revolutions completed.

6. If you pull out the drawer while

irradiation is in process, the Platter willstop rotating and the Shutter Light will

go out as the Shutter closes and rotation

stops. To restart, simply push the Drawer

back in and press the Start Button. The

irradiation will begin again from the

point where it was stopped.

7. When the required number of revolutions

is completed, the Shutter Light will go

out and a sounder will be activated. Press

the Reset Button on the Counter panel tosilence the sounder. You may now open

the Drawer and remove the disk.

8. Card irradiation only: Remove the

Cards from the Disk; turn each card

around in its recess and repeat steps 4

through 7. This is necessary because

only the two TL elements nearest the

periphery of the disk are irradiated.

4.0 Calibration

4.1 Chips

This section describes a procedure that

you may use to calibrate the Model 2210

Irradiator to a traceable calibration sourceusing unmounted TLD Chips. These

instructions require either a Harshaw Model

5500 Automated TLD Reader, a Harshaw

Model 4500 Manual TLD Reader, or a

Harshaw Model 3500 Manual TLD Reader.

1. Prepare five dosimeters by reading them

twice.

2. Place the five dosimeters at Positions 9,

18, 27, 36, and 45 in the Dosimeter Carrier. (Important: If you are using a

Model 5500 Reader, do not remove the

dosimeters from the Carrier Disk until the

entire calibration process is completed. If

your reader is a Model 3500 or a Model

4500, you will have to remove the

dosimeters from the disk to read them; be

sure to replace them in the same positions

in the Carrier Disk each time they are

irradiated.)

3. Expose the five dosimeters for 100

revolutions in the Model 2210 Irradiator

being calibrated. Keep the time period

between preparation and exposure (Steps

1 and 3) constant to reduce fading effects.

4. Read and reread the dosimeters and

record both readings for each dosimeter.

Keep the time period between exposure

and read (Steps 3 and 4) constant to

reduce fading effects.

5. Calculate the read minus reread value for

each dosimeter.

6. Prepare the five dosimeters again by

reading them twice.

7. Expose the dosimeters in a calibrated

source to a value of approximately 100

mR. Keep the time period between

preparation and exposure (Steps 6 and 7)

the same as between Steps 1 and 3 to

reduce fading effects.

8. Read and reread the dosimeters. Keep

the time period between exposure and

read (Steps 7 and 8) the same as betweenSteps 3 and 4 to reduce fading effects.

9. Subtract the reread values from the read

values.

10. Calculate the Conversion Factor for each

dosimeter by dividing the calibrated

exposure (Step 7) by the response (read

minus reread, Step 9).

11. Multiply the mean response (read minusreread, Step 5) by the Conversion Factor

(Step 10) for each dosimeter to get the

exposure values. Then compute the mean

exposure.

12. Divide the exposure by the number of

revolutions (100) to get the exposure rate

(exposure per revolution).

4.0 Calibration (cont’d)

4.2 Cards

This section describes a procedure that

you may use to calibrate the Model 2210Irradiator to a traceable calibration source

using TLD Cards. These instructions require

either a Harshaw Model 4500 Manual TLD

Reader, a Harshaw Model 6600 Automated

TLD Reader, or a Harshaw Model 8800

Automated TLD Reader.

1. Prepare five Cards by reading them

twice.

2. Place the five Cards in the five recessesin the Dosimeter Carrier. Orient the

cards with the barcodes facing up and

with elements i and iv toward the

periphery of the disk (that is, with the

notched corner toward the center of the

disk).

3. Expose the five Cards for 100 revolutions

in the Model 2210 Irradiator being

calibrated. Keep the time period between

preparation and exposure (Steps 1 and 3)constant to reduce fading effects. Note

that this will expose only the two TL

elements nearest the periphery of the

Disk. Only these two elements (i and iv)

will be used in the calibration process.

4. Read and reread the Cards and record

both readings for each of the exposed TL

element. Keep the time period between

exposure and read (Steps 3 and 4)

constant to reduce fading effects.

5. Calculate the read minus reread value for

each exposed element on each Card.

6. Prepare the five Cards again by reading

them twice.

7. Expose the Cards in a calibrated source to

a value of approximately 500 mR. Keep

the time period between preparation and

exposure (Steps 6 and 7) the same as

between Steps 1 and 3 to reduce the

difference in fading effects.

8. Read and reread the dosimeters. Keep

the time period between exposure and

read (Steps 7 and 8) the same as betweenSteps 3 and 4 to reduce fading effects.

9. Subtract the reread values from the read

values for the exposed TL elements.

10. Calculate the Conversion Factor for each

exposed element on each Card by

dividing the calibrated exposure (Step 7)

by the response (read minus reread, Step

9).

11. Multiply the mean response (read minus

reread, Step 5) by the Conversion Factor

(Step 10) for each exposed element on

each Card to get the exposure values.

Then compute the mean exposure for all

10 TL elements.

12. Divide the exposure by the number of

revolutions (100) to get the exposure rate

(exposure per revolution).

6.0 Leak Test

This section describes the leak tests

needed for the United States, Canada, and all

other countries.

Safety Precautions

1. Do not attempt to remove the 90 Sr Sealed

Source Capsule from its stored position

in the Shielded Source Housing.

2. Do not touch or handle the tip of the

cotton swab (or other collecting device)

used in collecting the leak test sample.

3. Do not allow the collecting device to

come in contact with the external surfaces of the container used to return

the sample for analysis.

6.1 United States Leak Test

In compliance with the U. S. Nuclear

Regulatory Commission (NRC), you are

required to test the Irradiator for leakage of

radioactive material. This is accomplished by

a wipe test, which is sufficiently sensitive to

detect 0.005 microcuries of radioactivity.

If you do not have provisions for wipetesting, you may order a kit from a supplier,

such as:

Applied Health Physics

2986 Industrial Blvd.

Bethel Park, PA 15102

412/563-2242

After receiving a kit, including

instructions, from the supplier, perform wipe

test, and return the sample to the supplier for evaluation. Upon request, most services will

provide a timely reminder as needed to

perform the wipe test. The following

instructions assume that you have obtained

such a kit.

Procedure1. Complete the Leak Test Data Form,

supplied with the Leak Test Kit, in a clear and legible manner.

2. Turn power off (switch is on rear panel).

3. Open the drawer. Remove the disk, if one is present, and remove any loosechips.

4. Remove the plastic-and-cotton swabinsert from the labeled plastic tube.Dampen the cotton tip with water.

5. Carefully wipe the surface of the disk support plate that is to the right of thealignment pin.

It is the user's responsibility to comply

with the requirements of the AECB (AtomicEnergy Control Board) Requirements for Leak

Testing Selected Sealed Radiation Sources, R-

116. This is accomplished by a wipe test and

must be sufficiently sensitive to detect 200 Bq

(0.005 µCi) or less of an isotope of interest.

Prepare the leak test in accordance with

AECB R-116. The leak check shall be

performed only by persons properly trained in

working with radioactive prescribed sources

and informed of the hazards involved and

allowed to handle radioactive prescribedsubstances. The swab must be analyzed by an

agency approved by the AECB.
