目的分析田湾核电站放射工作人员个人剂量水平。方法收集2007-2015年田湾核电站工作人员剂量数据进行分析。结果 2007-2015年田湾核电站人员年有效剂量均小于5 mSv,其中94.45%的人员年有效剂量在1mSv以下,人均年有效剂量平均为0.21 mSv/年。结论 2007-2015年田湾核电站放射工作人员年有效剂量均低于国家标准限值,电站辐射防护状况良好。
Objective To analyze the individual dose level of radiation workers in Tianwan Nuclear Power Station. Methods The dose data of Tianwan NPP collected during 2007-2015 were collected for analysis. Results The annual effective doses of Tianwan NPP were less than 5 mSv from 2007 to 2015, of which 94.45% were below 1 mSv and the average annual effective dose was 0.21 mSv / year. Conclusion The annual effective dosimeters of radiation workers in Tianwan Nuclear Power Plant from 2007 to 2015 are lower than the national standard limits and the radiation protection status of power plants is good.
