目的检验本中心个人剂量监测系统性能,探讨质量控制措施。方法总结本中心个人剂量监测系统2004～2011年六次参加全国盲样比对的结果,分析误差原因。结果本中心监测系统历次比对结果均合格,个人剂量监测系统质量控制措施良好。结论参加上级技术指导部门组织的盲样比对是个人剂量监测系统质量控制的重要一环,加强日常检测中的质量控制,对提高监测质量也有重要意义。
Objective To test the performance of personal dose monitoring system in our center and to explore quality control measures. Methods Summarize the results of blind spot-like alignment of the individual dose monitoring system in our center from 2004 to 2011, and analyze the causes of errors. Results All the results of the comparison of the monitoring system in this center were qualified, and the quality control measures of personal dose monitoring system were good. Conclusion The blind-like comparison of the organizations participating in higher technical guidance departments is an important part of the quality control of personal dose monitoring system. Strengthening quality control in routine testing is also of great significance for improving the quality of monitoring.
