Abstract
According to the ionizing radiation safety regulation approved by the ROC Atomic Energy Council (AEC), personnel dosimeter processors shall be qualified by the Chinese National Laboratory Accreditation (CNLA) program before offering dosimeter services and shall be requalified every two years. The Institute of Nuclear Energy Research (INER) was entrusted by CNLA as the central laboratory to perform the proficiency test of personnel dosimeters for laboratory accreditation in December 1990. Such proficiency tests, based on ANSI N13.11 (1983), have been conducted three times, in 1991, 1993 and 1995, to accommodate for dosimeter processors' need for requalification every two years. The results of the latest proficiency test showed that, among the nine participants, six participants tested with eight categories all passed the test. Of other three participants tested with six categories, two passed the test and one failed this test in two categories. The central laboratory will adopt the new version of HPS N13.11 (1993) to replace ANSI N13.11 (1983) as new criteria for the next proficiency test to be conducted in 1998.
