摘　　要：目的通过分析2019年参加全国放射工作人员个人剂量监测能力考核结果,了解本省实验室个人剂量监测系统运行状况,进一步提高监测能力和水平。方法参加2019年全国放射工作人员个人剂量监测能力考核,并对考核结果进行分析总结。结果本次能力考核检测报告获得满分10分,且单组性能偏差在-0.04~0.01(均符合|Pi|≤0.10),同时综合性能偏差B2+S2≤0.10(B为综合判定指标,S为综合标准偏差),故而实验得70满分,总分达到80分可参加评定优秀的要求,经评定质控分为17.3分,Q值为97.3(Q值≥95为优秀),故本实验室个人剂量监测能力考核结果为优秀。结论宁夏个人剂量监测实验室系统运行良好,检测结果准确、误差范围较小,可满足国家职业性外照射个人剂量监测相关标准要求。Objective To understand the operation status of personal dose monitoring system in provincial laboratory by analyzing the assessment results of personal dose monitoring ability of national radiation workers in 2019, to further improve the monitoring ability and level of Ningxia. Methods The provincial laboratory participated in the National Radiation Workers’ personal dose monitoring ability assessment in 2019, and the assessment results were analyzed and summarized. Results In this comparison, 10 full marks were obtained for the ability assessment results of the test report, and the single group performance deviation was-0.04~0.01(all in line with |P_i| ≤ 0.10), while the comprehensive performance deviation was B^2 + S^2 ≤ 0.10(B was the comprehensive judgment index, S was the comprehensive standard deviation). Therefore, 70 full marks could be obtained for the experiment, and the total score could meet the requirements of 80 points to qualify for participating in the evaluation of excellence. After evaluation, the quality control score was 17.3 points, the Q value was 97.3(excellent if Q ≥ 95), so the assessment result of individual dose monitoring ability of the laboratory wsa excellent.Conclusion The assessment results show that the system of Ningxia individual dose monitoring laboratory operates well,the test result is accurate and the error range is small, which can meet the requirements of relevant national standards for individual dose monitoring of occupational external exposure.
