核工业系统的一次防护级和环境级X、γ剂量仪表比对

INTERCOMPARISON OF X, γ INSTRUMENTS FROM NUCLEAR INDUSTRY SYSTEM USED FOR RADIATION PROTECTION MEASURING AND ENVIRONMENTAL MONITORING

中国核工业放射性计量测试中心于1988年3—4月组织了一次该系统内的防护级和环境级X、γ剂量仪表比对。参加比对的有10个单位的19台仪表,其中防护级仪表11台,环境级仪表8台。比对结果表明,目前该系统内剂量监测质量保证方面还存在一些问题,尤其是大部分仪表未能定期送检和一些环境监测仪表能响太差,还有些作为实验室标准的仪表最大偏差达14％左右。

An intercomparison of X,γdosimeters of radiation protection level and environmental level was organized by the Radiome-trology Centre of Nuclear Industry in March-April, 1988. There were 19dosimeters from 10 user units to be checked in the intercomparison.Among them, 11 were radiation protection instruments and 8environmental instruments. The results of the intercomparison showedthat there were some problems in quality insurance for dose measurementin nuclear industry system. Specially most dosimeters were failed to becalibrated regularly, and the energy dependence of some environmentalsurvey meter were too poor. Forthermore, the maximun deviation of somelaboratory reference instruments were as high as about 14%.
