| 摘 要： | 目的了解四川省放射工作人员个人剂量水平,为放射防护提供科学依据。方法采用热释光剂量测量方法对四川省2009年放射工作人员进行监测,并与2008年的总体监测结果进行比较分析。结果 2009年全省共监测7 871人,年人均有效剂量为0.93 mSv/a,年集体剂量为7.34人.Sv,年有效剂量小于5 mSv/a的人员占99.82%,有0.15%的人员超过20 mSv/a,有0.03%的人员超过50 mSv/a国家标准规定放射工作人员年剂量限值。2008年全省共监测7 499人,年人均有效剂量为1.03 mSv/a,年集体剂量为7.79人.Sv,2009年相比2008年监测人数增加了4.96%,年人均有效剂量下降了11.84%,年集体剂量下降了6.15%。结论四川省放射工作人员个人剂量人均有效剂量呈现下降趋势,防护措施比较完善,四川省放射防护工作取得良好的管理效果。

| Abstract: | Objective To understand individual dose level of the workers with external exposure to radiation in Sichuan province,and provide evidence to radiation protection.Methods Thermoluminescence dosimetry method was used to conduct surveillance among the workers exposed to radiation in Sichuan in 2009,the results were compared with that in 2008.Results A total of 7871 workers were surveyed in 2009.The annual effective dose per capita was 0.93 mSv/a.The annual collective dose was 7.34(per capita,Sv).The workers wi... |
