摘　　要：目的为了提高放射卫生技术机构个人剂量监测能力,规范检测方法与流程。方法依据GBZ 207—2016《外照射个人剂量系统性能检验规范》的相关内容制定详细考核方案,组织2020年全国个人剂量监测能力考核,分析考核中出现的问题并在日后加强监督培训。结果本次考核共有457家机构参加,其中421家合格(含优秀74家,优秀率为16.2%),36家不合格,分别占92.1%和7.9%。结论本年度参加考核的机构数量创历史新高,合格率较2019年提高4.08%,全国整体监测能力有较大提升。但仍有部分机构存在符号书写不规范、检测标准未更新、检测数据偏差大等问题,需要提高实验检测能力与数据分析能力,规范操作过程,保证考核质量。Objective In order to improve the personal dose monitoring ability of radiation health technical institutions,and standardize the detection methods and procedures. Methods Develop adetailed assessment plan according to GBZ 207—2016 "Testing criteria of personnel dosimetry performance for external exposure", organize a national assessment of personal dose monitoring capabilities in 2020, analyze the problems arising from the assessment, and strengthen supervision and training in the future. Results A total of 457 institutions participated in this assessment, of which 421 were qualified(including 74 excellent institutions, with an excellent rate of 16.2%), and 36 were unqualified, accounting for 92.1% and 7.9% respectively. Conclusion The number of institutions that participated in the assessment this year reaches a record high, with a passing rate 4.08% higher than that in 2019. The overall monitoring capacity of the country has been greatly improved. However, some institutions still have problems such as irregular symbol writing, unupdated detection standards, and large deviations in testing data. It is necessary to improve the ability of loboratory detection and data analysis, standardize the operation process, and ensure the quality of assessment.
