摘要
目的通过分析总结参加2018年度全国个人剂量监测能力考核结果,检验实验室个人剂量监测能力,查找缺陷和不足,进一步提高个人剂量监测能力和结果准确性。方法按照中国疾控中心辐射安全所指定的考核方案,参加2018年度全国个人剂量监测能力考核。结果5组考核组测量值与约定真值的单组性能偏差Pi值分别为-0.03、-0.13、-0.03、-0.12和-0.02,综合性能为0.007。根据判定标准单组性能判定和综合性能均合格。结论本实验室个人剂量监测系统性能稳定可靠,结果准确,符合国家有关标准的要求。但仍需加强质量控制,规范操作流程以进一步提升个人剂量监测能力。
Objective To inspect the personal dose monitoring capability of our laboratory and identify the defects or deficiencies for further improvements.Methods According to the designated assessment plan issued by the National Institute for Radiological Protection of China CDC,participate in the 2018 national intercomparisons.Results The single group performance deviations(Pi values)between the measured values and references of the 5 groups were-0.03,0.13,-0.03,0.12 and-0.02,respectively,and the overall bias(B value)of all groups was 0.007.According to the judgment standards,both the single group performance and overall performance were all qualified.Conclusion Our laboratory's personal dose monitoring system is stable and reliable,with accurate results and meets the requirements of relevant national standards.However,there is still a need to strengthen the quality control and standardize operational procedures to further enhance the individual dose monitoring capability.
