摘要
目的规范个人剂量监测技术服务机构的个人剂量监测工作,提高监测能力和水平。方法汇总2015—2019年全国外照射个人剂量监测能力考核的结果,并对考核中出现的问题进行总结与分析。结果截至2019年,来自全国30个省、自治区或直辖市的个人剂量监测技术服务机构参加了全国外照射个人剂量监测能力考核,涉及的机构有疾控中心、职防院(所)、科研院所、大专院校、核工业、医疗机构及民营技术机构等。参加考核的机构数从202家增加到382家。考核结果除2017年的合格率略低,其他4年的合格率均高于90%。优秀率随着年份的增加而增加。结论2015—2019年全国外照射个人剂量监测技术服务机构测量能力满足个人剂量监测需求,能出具符合标准的检测报告,但尚有一些机构未能合格,相关机构应仔细分析查找不合格的原因,规范实验室的质量控制手段,提高测量水平和数据分析能力。
Objective To enhance the capabilities of individual monitoring technology services for external exposure.Methods The intercomparison results of the national individual monitoring for external exposure during 2015-2019 were presented,together with a summary and analysis provided of the main existing problems.Results By 2019,382 of individual monitoring technology service uints,from 30 provinces,autonomous regions or municipalities,participated in the individual monitoring intercomparisons results,involving disease control and prevention centers,occupational prevention and control institutions,research institutes,universities,nuclear industry,medical institutions,and companies.Except for slightly low in 2017,the pass rate in the other four years was above 90%.The excellence rate increased with the years.Conclusions The capabilities of individual monitoring service units can meet the concerned requirements and provide standardized monitoring report for the period of 2015 to 2019,but with some being unqualified.These service units should carefully analyze and identify the reasons for the failure,standardize the quality control of laboratory,and improve the level of measurement and the ability of data analysis.
