Kathy Pryor Past President, Health Physics Society Chair, Health Physics Society Awards Committee

Dear Award Committee Members:

It is my pleasure to support the nomination of Dr. Charles “Gus” Potter for the HPS Fellow

Award. Gus is an outstanding Health Physicist who has made substantial scientific and educational

contributions to our field. Gus is a distinguished alumnus of the University of Massachusetts Lowell

Radiological Sciences program. I first met Gus when he entered our graduate program in 1987 during

which I was a professor of several of his classes and a member of his doctoral committee. I have

followed Gus’ career over the years and have collaborated with Gus on many internal dosimetry

projects. I can attest to Gus’ accomplishments and believe that he is very deserving of this honor.

Although Gus’ many scientific contributions have been impressive and diverse, I view his work

in internal dosimetry to be truly outstanding. In addition to his work at Sandia National Laboratories he

has worked with the NCRP, EPRI, ANSI, IAEA, HPS, and many industries on internal dosimetry. Gus’

publication of intake retention functions is an invaluable set of benchmarks for internal dosimetrists

worldwide. Gus is the only author to have an entire issue of the Health Physics Journal dedicated to his

work.

Gus has been an adjunct faculty at the University of New Mexico for more than 20 years,

teaching courses on internal dosimetry and advising graduate students on their projects and theses. Gus

has been very active in the HPS, chairing many sessions at annual meetings, chairing local arrangement

committees, and holding many offices in his local chapter of HPS, including president. As a certified

health physicist, Gus has been a board member of the ABHP and has served many years on the

examination panels including chairing several part II exam panels.

Dr. Potter’s scientific and educational contributions to our profession are substantial and

impressive. I support his nomination for the HPS Fellow Award without reservation.

Sincerely,

Clayton S. French

Prepared section on analysis of dosimetry results for final report including evaluations ofwhole-body, extremity, and internal dose.

Continuous Intake Replacement Function Completed 2012Derived continuous intake retention replacement function for general use. Significance of derivationwas that the limitations of a published replacement function were determined and the function wasre-derived for general usage. The need for a continuous function came about when doses were beingcalculated for a tritium waste campaign. This activity resulted in a note being published in HealthPhysics.

EXTRAD 4100S Extremity Dosimeter Algorithm Completed 2010Rewrote algorithm for EXTRAD 4100S Extremity Dosimeter. This required evaluating responsedata to irradiated doses and developing a mathematical three-part algorithm for evaluation of ex-tremity doses. This updated algorithm replaced a previous one and eliminated a requirement forthe dosimeter to be issued with two separate colored straps that indicated the use of one of twoseparate algorithms.

Quality Control Program Redevelopment Completed 2009Redeveloped quality assurance/control program for external dosimetry. Reviewed quality elementsof all aspects of the program and determined their appropriateness or whether additional elementsshould be added. Overall program is described in quality program document that was rewrittenfrom scratch and implemented in dosimetry processes and procedures and is compliant with theDepartment of Energy Laboratory Accreditation Program and Title 10 Code of Federal RegulationsPart 830 requirements.

Neutron Technical Basis Completed 2009Updated neutron technical basis to incorporate both change to Thermo/Harshaw Model 8825 andchange in neutron radiation weighting factor published in a revised Title 10 Code of Federal Reg-ulations Part 835 incorporating recommendations from ICRP Publication 74. A graduate student(Daniel J. Sanchez, University of New Mexico) was engaged and provided training on the MCNPMonte-Carlo transport code. Monte-Carlo calculations of the expected neutron response of thedosimeter using the ICRP Publication 74 neutron factors were performed and new dose conversionfactors for dosimeter response were derived for the 8825 dosimeter. This work was presented at the2007 meeting of the Health Physics Society.

Thermo 8825 Dosimeter Deployment Completed 2009Implemented upgrade of personnel dosimeter from Thermo/Harshaw Model 8802 to Thermo/HarshawModel 8825.

Z-Machine Beryllium Contamination Investigation Completed 2004Participated on SNL investigation of beryllium contamination at SNL’s Z-Machine facility. Thisproject involved reviewing operations, interviewing individuals, and drawing conclusions as to thetime line and reasons for the contamination. The result of the investigation was a report for labora-tory management that included recommendations for future actions to mitigate the existing situationand ensure that further contamination was minimized.

Tritide Model Development Completed 2004Developed and implemented tritium bioassay and internal dosimetry program based on the ICRP-88Clarification of the ICRP-56 tritium model. The source term includes tritium in gaseous, organic,tritide, and oxide forms. The resolution of the ICRP models developed in the course of this workhas been published in Health Physics.

Transition of Uranium Analysis Methods Completed 2004Changed analysis of uranium bioassay samples from kinetic phosphorescence analysis to inductively-coupled plasma mass spectrometry. Upon the development of this capability by SNL’s RadiationProtection Sample Diagnostics Program, devised a plan for implementation that included admin-stration of a quality assurance program and, ultimately, accreditation by the Department of EnergyLaboratory Accreditation Program for Radiobioassay. Upon implementation of this plan, SNL wasthe first laboratory in the complex to have this capability accredited.

Intake Retention Fraction Derivation Completed 2002Developed intake retention fractions for implementation of ICRP-68 family of internal dosimetrymodels. This included resolution of the ICRP-66 respiratory tract model with default parameters.The results of this project were published in a stand-alone issue of Health Physics which is the onlyentire issue to be authored by a single individual.

Self-Governance Completed 2002Participated in lab self-governance initiative. The project was to develop an infrastructure whereDOE and federal requirements were implemented and assessed through SNL programs and oversightwould be limited to review of those programs. Specifically, worked with team to develop corporateassurance framework.

Dosimeter In-house Processing Reinstatement Completed 2001Reinstated in-house dosimeter processing capability after program had been outsourced. This in-cluded training and qualifying technicians on Harshaw 8800 Dosimeter Readers, restoring the quality

7

control blind audit program, and reviewing/revising each process to ensure quality and compatibilitywith program and customer requirements.

125I Production 2000 – 2002Developed thyroid monitoring program for 125I production activities. This included weekly thyroidmonitoring for individuals performing operations. Success of program as last line of defense wasshown when contamination area not detected by radiological survey methods was found by positivethyroid count on an individual. Using available urinalysis data from diagnostic administration of131I to athyrotic individual, developed retention function for iodine intake. This was used to evaluateurine data for athyrotic individual working in 125I production activities. Results of this work werepublished in Health Physics.Aspects of this program were published in two papers.

ALARA Committee 1999 – 2000Participated in SNL’s ALARA committee as member. Rewrote ALARA chapter of Radiation Pro-tection Procedures Manual in 1999. Chaired committee in 2000.

MARSSIM Scanning Speed Study 1998Worked with a small team to develop a technical basis for the speed of detection probe scanningduring radiological surveys to ensure identified detection limits were met. The process was devel-oped using guidance from the Multi-Agency Radiation Survey and Site Investigation Manual andboth scanning speeds and requirements for static counts were obtained. Results of this study wereincorporated into procedures used by the Radiation Protection Operations program.

Radiation Protection Procedures Manual 1998Participated in the development of the SNL Radiation Protection Procedures Manual. This was inresponse to the publishing of Title 10 Code of Federal Regulations Part 835 on radiation protectionin Department of Energy facilities. Initially developed internal dosimetry sections of Chapter 4,Radiation Dosimetry. This was presented to a laboratory population and subjected to considerablereview. Upon inclusion in the manual, was responsible for continued review and update. Whengiven external dosimetry responsibility, was ultimately responsible for maintenance of entire chapter.Completely revised chapter in 2009 to implement requirements in updated regulation reflectingchanges in ICRP Publication 60 recommendations.

Exposure Monitoring Program Development Completed 1998Implemented exposure monitoring program for internal dosimetry. This program includes use ofpersonal air sampling in airborne radioactivity or contamination areas. Exposure is monitored andresults are used to determine if further bioassay sampling is required. Confirmatory monitoring ona select group of individuals is used as a quality control measure.

Sample Management Office 1997Acted as project lead for the SNL Sample Management Office for several months in 1997. Thisincluded managing a staff of seven including professional staff and administrators, technologists,and administrative staff. Negotiated sample loads and funding with environmental restoration andenvironmental monitoring programs. Program included both administration of laboratory analysiscontracts and verification of data upon completion of analysis.

Industrial Hygiene Laboratory Statement of Work Completed 1997Worked with team as consultant on developing a statement of work for the in-house analyticalchemistry laboratory whose primary customer was the industrial hygiene program. Confidence inthat laboratory’s quality systems had degraded over time, and the statement of work was usedas a mechanism to improve the laboratory’s performance and provide a level of confidence for theindustrial hygienists.

Internal Dosimetry Program Development Completed 1995

8

Developed and implemented internal dosimetry program at SNL. Developed technical basis for lim-ited bioassay sampling to be used as quality control on radiation protection program rather thanextensive routine program. Combining this type of confirmatory monitoring with reliance on work-place control and exposure monitoring has saved SNL hundreds of thousands of dollars in unnecessarysampling over the life of the program.

Tiger Team Milestones Completed 1995A main responsibility upon being hired by SNL was to respond to and complete a lengthy series ofmilestones previously developed to respond to a Department of Energy Tiger Team Assessment thatoccurred at SNL in the 1990 time frame. These milestones addressed the basic development of aninternal dosimetry program including in vivo and in vitro analysis capabilities, staffing, and qualityassurance and control among other topics. All milestones were completed by their due dates andevidence provided to the corporate entity.

Depleted Uranium Issues 1993Developed and gave presentation on internal dose and biological effects of depleted uranium. Duringthe first gulf war, concerns were brought up by SNL employees about the use of depleted uranium atSNL and possible health effects. SNL prepared a several hour session describing the use and hazardsof depleted uranium and the possibility of adverse effects on personnel. The opportunity to providebioassay samples for analysis was presented and a large number of SNL personnel took advantage.Results were obtained and evaluated and feedback provided to participants.
