目的检验外照射个人剂量监测水平和测量结果的可靠性。方法参加2009年全国个人剂量监测盲样比对。结果单组性能Pi和综合性能∣B∣+S最大为4.67%,远小于40%的判定水平。结论本实验室个人剂量监测系统的数据在比对剂量范围内的准确性、稳定性均较好,监测技术能满足外照射个人剂量监测的性能要求。
Objective To test the level of external dose monitoring and the reliability of measurement results. Methods Participate in the 2009 national individual dose monitoring blind sample comparison. Results Single group performance Pi and comprehensive performance | B| + S up to 4.67%, far less than 40% of the decision level. Conclusion The accuracy and stability of the data from the personal dose monitoring system in the laboratory range are good, and the monitoring technology can meet the performance requirements of external dose monitoring.
