摘　　要：目的:调研北京市某三级综合医院2013年1月~2016年12月放射工作人员个人剂量监测基本情况。方法:通过佩戴Li F(Mg,Cu,P)热释光剂量计(TLD)以年度为单位监测并进行分析和评价,评价标准依据国家相关法律法规和技术规范。结果:2013-2016年全院外照射人均年剂量当量分别为0.22m Sv/a、0.18m Sv/a、0.20m Sv/a、0.22m Sv/a,X线影像诊断、介入放射学、核医学、放射治疗工种人均年平均剂量当量分别为0.16m Sv/a、0.18m Sv/a、0.47m Sv/a、0.19m Sv/a。结论:该医院绝大多数放射工作人员的个人剂量水平较低,说明放射工作人员所处放射工作环境安全,应关注重点工种人员在放射防护实践中的个人剂量监测与防护,增强工作人员的防护意识。Objectives： To investigate status quo of radiation workers＇ personal doses surveillance in a tertiary general hospital in Beijing during January 2013 to December 2016. Methods： LiF（Mg,Cu,P） thermos luminescent dosimeters（TLDs） were used in the regular data collection. The data were analyzed according to the laws and regulations and technical standards. Results： It shows that the average external exposure doses were 0.18 mSv/a, 0.20mSv/a, 0.22 mSv/ a,0.22mSv/a from 2013 to 2016.X-ray imaging diagnosis, interventional radiology, nuclear medicine and radiation therapy work average doses were 0.16 mSv/a, 0.18mSv/a, 0.47mSv/a, 0.19mSv/a. Conclusion： The majority doses level of the radiation workers in the hospital are lower than standard and their working environment is safe. Indeed, both strengthening on personal doses monitoring and individual protection should be emphasized in regular working practice.
