目的:检验本实验室放射卫生监测能力水平,保证监测结果的准确可靠,持续进行质量控制。方法方法:依据中国疾病预防控制中心辐射防护与核安全医学所组织的全国职业性外照射个人剂量监测系统质量控制比对方案,2011年、2014年、2015年、2016年4次参加全国放射工作人员热释光个人剂量计盲样比对。结果结果:2011年热释光个人剂量监测系统比对结果为优秀,2014年、2015年、2016年为合格。结论:本实验室个人剂量监测系统数据准确可靠、设备性能稳定,监测技术满足外照射个人剂量监测的有关性能要求;但对于本实验室系统误差的质量控制仍是个人剂量监测的重点。
OBJECTIVE: To test the level of radiation health monitoring capability in our laboratory to ensure the accuracy and reliability of monitoring results and to continuously carry out quality control. Methods and Methods: Based on the quality control comparison program of the national occupational external exposure personal dose monitoring system organized by the Radiation Protection and Nuclear Safety Medicine Center of China CDC, participated in the national radiological work in 2011, 2014, 2015 and 2016 Personnel thermoluminescence personal dosimeter blind comparison. Results: The results of the comparison of the thermoluminescence personal dose monitoring system in 2011 were excellent, and were satisfactory in 2014, 2015 and 2016. Conclusion: The data of personal dose monitoring system in our laboratory are accurate and reliable, and the performance of the device is stable. The monitoring technology meets the performance requirements of external dose monitoring. However, the quality control of systematic errors in our laboratory is still the focus of personal dose monitoring.
