个人剂量监测参考辐射场刻度剂量比对校准

摘要

介绍秦山核电厂个人剂量双轨监测工作中以热释光个人剂量计开展参考辐射场刻度剂量比对校准的方法，以及2001-2012年秦山核电厂与中国辐射防护研究院进行的参考辐射场刻度剂量比对的结果。比对结果表明，对参考辐射场的剂量比对，其照射剂量与约定照射真值之间的相对偏差控制在±5％以内。以2008年上半年参考辐射场刻度剂量比对校准工作为实例，对辐射场刻度剂量比对过程中出现的问题进行了分析解决。%An introduction is made to the methodologies in which both intercomparison and calibration are conducted for individual dose monitoring center and TLD reference radiation fields , together with the 2001-2012 inter-comparison results between QNNP and CIRP . The results indicate a bias within ± 5% between measured results and conventional true values .The problems existing in the intercomparison are analyzed and solved on the basis of the work in fist half of 2008 .
