The University of Michigan conducted a two-year pilot study of the Health Physics Society Standards Committee (HPSSC) Standard, 'Criteria for Testing Personnel Dosimetry Performance.' After the pilot study was concluded on September 27, 1979, the HPSSC Standard was revised based, in part, on experiences and recommendations derived from the pilot study. The Nuclear Regulatory Commission extended the contract under which the pilot study was conducted primarily so the data produced during the pilot study could be examined using the revised HPSSC Standard. The results of this extension to the pilot study show that the passing rate increases substantially when the revised version of the Standard is used instead of the original version. Data are also given that show the percent of dosimeters used in the United States that are being processed by processors that passed the revised version of the HPSSC Standard. Finally, data are given that show that the production of bremsstrahlung is negligible for the strontium-90 source used during the pilot study, but that a processor that uses a deep depth considerably less than 1000 mg/sq. cm. will over-estimate deep doses for beta-plus-gamma irradiations.

A two-year pilot study was conducted of the Health Physics Society Standards Committee (HPSSC) Standard titled, Criteria for Testing Personnel Dosimetry Performance. The objectives of the pilot study were: to give processors an opportunity to correct any problems that are uncovered; to develop operational and administrative prodedures to be used later by a permanent testing laboratory; and to determine whether the proposed HPSSC Standard provides an adequate and practical test of dosimetry performance. Fifty-nine dosimetry processors volunteered to submit dosimeters for test irradiations according to the requirements of the HPSSC Standard. The feasibility of using the HPSSC Standard for a future mandatory testing program for personnel dosimetry processors is discussed. This report shows the results of the pilot study and contains recommendations for revisions in the Standard that will make a mandatory testing program useful to regulatory agencies, dosimetry processors, and radiation workers that use personnel dosimeters.

This standard is intended to be used in the Department of Energy Laboratory Accreditation Program (DOELAP) for personnel dosimetry systems. It is based on the American National Standards Institute's (ANSI) ''Criteria for Testing Personnel Dosimetry Performance, '' ANSI N13.11-1983, recommendations made to DOE in ''Guidelines for the Calibration of Personnel Dosimeters, '' Pacific Northwest Laboratory (PNL)-4515 and comments received during peer review by DOE and DOE contractor personnel. The recommendations contained in PNL-4515 were based on an evaluation of ANSI N13.11 conducted for the Office of Nuclear Safety, DOE, by PNL. Parts of ANSI N13.11 that did not require modification were used essentially intact in this standard to maintain consistency with nationally recognized standards. Modifications to this standard have resulted from several DOE/DOE contractor reviews and a pilot testing session. An initial peer review by selected DOE and DOE contractor representatives on technical content was conducted in 1983. A review by DOE field offices, program offices, and contractors was conducted in mid-1984. A pilot performance testing session sponsored by the Office of Nuclear Safety was conducted in early 1985 by the Radiological and Environmental Sciences Laboratory, Idaho Falls. Results of the pilot test were reviewed in late 1985 by a DOE and DOE contractor committee. 11 refs., 4 tabs.
