热释光个人剂量监测系统及其质量控制

摘要

目的：采取系列热释光个人剂量测量(TLD)系统质量控制措施，保证热释光个人剂量监测系统稳定可靠。方法：制定质量控制体系文件，严格规范个人剂量检测流程，对个人剂量测量系统采取定期维护保养、检定、期间核查及长期稳定性监测等质量控制措施。结果：通过对热释光个人剂量测量系统采取质量控制，在2014年的全国放射卫生技术服务机构个人剂量比对中取得了较好的成绩，参比的剂量计单项性能|Pi|≤0.1，综合性能|B|+S≤0.1，比对结果为优秀。结论：对热释光个人剂量测量系统采取的质量控制措施有效可行，个人剂量监测系统基本稳定可靠。%Objective:To guarantee the stable and reliable performance of TLD individual monitoring system through a series of quality control measures.Methods: To establish the documents of quality control system and standard measurement procedure for TLD. The measures of maintenance, calibration and intermediate check of the TLD monitoring system were taken periodically.Results: Compared with the national individual monitoring, TLD system for individual monitoring achieved good results in 2014 with the |Pi|≤0.1, |B|+S≤0.1. Conclusions: Quality control methods are taken effectively and performance of individual monitoring system is stable and reliable.
