Study for setting standards for performance testing of personal extremity dosimeters

As the needs and opportunities for utilization of atomic energy and radiation are increasing, the related industries, medicines, environments are developing and the relevant organizations and companies are also becoming diverse. In result, the types and kinds of the radiation related to occupational environments are becoming diversified. For the whole body dosimeters, the methodology and criteria for the performance evaluation and safety regulations and laws have been prepared in some detail, but for the extremity dosimeters, those are not prepared yet in Korea. The extremity dosimeters are required when the extremity part of our body, such as hand, elbow, and arm below the elbow, the foot, Knee, and leg below the knee are exposed to the radiation in specific work environments. The dosimeter irradiation conditions are discriminated between the whole body exposure condition and the extremity exposure condition. By the investigation and analysis of the management status and performance testing methods of the extremity dosimeters for the local absorbed dose, this study diagnose the evaluation system of the extremity dosimeter services and investigate the test procedures and performance criteria recommended by the ANSI 13.32, etc. Therefore, this study, by performing the preliminary experiments, presents and describes the criteria for acceptable performance and standardized testing conditions such as administrative procedures, test categories, test ranges, radiation sources, phantom design, irradiation conditions, selection of irradiation levels, assignment of dose equivalent, for personnel extremity dosimeters services. And so the basic data-base which can be applicable for dosimetry for health protection was presented for KINS to regulate the personnel extremity dosimeters services for domestic work places
