目的掌握各类放射工作人员受照剂量水平,为改善辐射防护措施提供依据。方法对2009～2010年放射工作人员外照射个人剂量监测资料进行分析。结果二年间,共监测放射相关单位229家次,放射工作人员1412人次;2009年、2010年人均年有效剂量分别为0.381mSv·a-1、0.553mSv·a-1;医疗相关放射工作人员人均年有效剂量为0.348mSv·a-1,工业相关放射工作人员人均年有效剂量为0.546mSv·a-1。结论放射工作人员外照射剂量处于较低水平,工业相关放射工作人员的防护工作仍需加强。
Objective To master the dose levels of various radiation workers and provide the basis for improving radiation protection measures. Methods The data of external dose monitoring of radiation workers from 2009 to 2010 were analyzed. Results During the two years, a total of 229 radiation-related units were monitored and 1412 radiological workers were monitored. The annual effective doses per capita in 2009 and 2010 were 0.381mSv · a-1 and 0.553mSv · a-1, respectively. The average number of medical-related radiation workers per capita The annual effective dose is 0.348mSv · a-1, and the per capita effective dose of industrial-related radiation workers is 0.546mSv · a-1. Conclusion The external exposure dose of radiation workers is at a low level, and the protection of industrial radiological workers still needs to be strengthened.
