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.
