[目的]通过个人剂量盲样比对检验参比实验室个人剂量监测系统整体技术水平。[方法]按照《全国放射工作人员个人剂量监测系统比对方案》,某实验室2010年至2012年连续3次参加由中国疾病预防控制中心辐射防护与核医学安全所组织的全国外照射个人剂量监测盲样比对。[结果]2010年比对实际测量值与约定真值的相对偏差在±18%以内;2011年和2012年单项性能和综合性能均在±10%以内,3次盲样比对结果均符合国家相关标准要求。[结论]该实验室个人剂量监测系统整体技术水平符合国家相关标准要求。
[Objective] To test the overall technical level of personal dose monitoring system in reference laboratory through blind comparison of individual dose. [Method] According to the “National Radiation Workers Personal Dose Monitoring System Comparison Program”, a laboratory from 2010 to 2012, three consecutive times by the Chinese Center for Disease Control and Prevention radiation protection and nuclear medicine safety organized by the national personal dose of external exposure Monitoring blind comparison. [Results] The relative deviation between actual measured value and agreed true value in 2010 was within ± 18%. The single performance and comprehensive performance in 2011 and 2012 were within ± 10%. The results of three blind-like comparisons were in line with the national Relevant standards. [Conclusion] The overall technical level of the laboratory personal dose monitoring system conforms to the requirements of relevant national standards.
