摘要
目的 分析全国个人剂量监测比对过程,检验个人剂量监测能力,保障实验室监测结果的准确性和可靠性。方法 依据2019—2021年的比对方案,准备能量鉴别式热释光剂量计,测量相应的剂量结果,同时进行不确定度评定,然后与参考值进行比较。结果 2019—2021年的比对目标量均为Hp(10)。2019年单组性能差异为-0.02~0.02,综合性能为0.02;2020年单组性能差异为0.02~0.10,综合性能为0.05;2021年单组性能差异为-0.02~0.02,综合性能为0.01。连续3年的比对结果均被比对组织者判定为优秀。结论 本实验室的个人剂量检测系统运行的质量控制状况良好,检测结果准确、可靠。重视刻度工作和提升人员知识水平是比对乃至个人剂量监测工作的重点。
Objective To analyze the process of intercomparison of national personal dose monitoring,evaluate the ability of personal dose monitoring,and ensure the accuracy and reliability of monitoring results in our laboratory.Methods In accordance with the intercomparison protocol for 2019—2021,an energy-discriminant thermoluminescence dosimeter was used for measurement at different doses.The uncertainty of measurement was evaluated and compared with the reference value.Results Hp(10)was measured for intercomparison in 2019—2021.In 2019,the single group performance difference was−0.02 to 0.02 and the comprehensive performance was 0.02.These values were 0.02-0.10 and 0.05 in 2020,and−0.02 to 0.02 and 0.01 in 2021.The intercomparison results were rated as excellent in the three consecutive years.Conclusion The personal dose monitoring system in our laboratory was in good condition,and the monitoring results were accurate and reliable.Improving the knowledge of personnel and cultivating a serious working attitude are important for intercomparison and personal dose monitoring.
