2017年全国外照射个人剂量监测能力考核结果与分析

Comparison and analysis of intercomparison results of national external irradiation individual dose monitoring in 2017

目的 规范全国放射工作人员职业性外照射个人剂量监测工作，提高放射卫生技术服务机构个人剂量监测能力和水平。方法 开展2017年全国外照射个人剂量能力考核工作，并对存在的主要问题进行分析总结。结果 参加本次个人剂量能力考核的有效单位为283家，合格的单位249家（包括优秀单位），不合格的单位34家。优秀的单位45家，优秀率为15.9%，合格率为88.0%。结论 大多数参加考核的检测机构能根据组织者提供的考核方案，较好地完成能力考核工作，但一些机构的考核结果与参考值的偏差较大，需要加强实验操作及规范数据处理过程，从而提高测量结果的准确度和精确度。

Objective To normalize the individual dose monitoring for nationwide radiological workers and to improve individual dose monitoring ability of radiological health monitoring service institutions. Methods The 2017 annual intercomparison was carried out of nationwide external radiation individual dose monitoring result, with summary and analysis completed. Results A total of 283 monitoring service institutions were involved in the 2017 annual intercomparison. Of them, 249 were qualified, 45 excellent and 34 unqualified. The excellent rate was 15.9% and the pass rate 88.0%. Conclusions Most of individual dose institutions could meet better the requirements by the intercomparison, but some deviated from the references to some degree. It is necessary to strengthen the laboratory operation and standardize data processing and to improve the accuracy end precision of measurement result.
