摘　　要：目的了解江苏省2011—2018年放射工作人员个人剂量监测基本情况,分析其变化趋势,为保护放射工作人员健康管理提供理论基础和科学依据。方法通过国家个人剂量登记系统,采集我省放射工作人员职业外照射个人剂量监测结果等相关数据,对其进行回顾分析。结果2011—2018年监测江苏省放射工作人员共176134人,总年集体有效剂量58人·Sv,期间人均年有效剂量为0.35 mSv。医用放射工作人员中从事介入放射学、核医学人均年有效剂量均为0.41 mSv,其高剂量人员构成比显著高于其他职业类别(χ^(2)=219.1,P<0.05)。至2018年医疗放射工作人员为25714人,占81%,年平均有效剂量为0.24 mSv;工业放射工作人员为6169人,占19%,年平均有效剂量为0.18 mSv。结论江苏省放射工作人员人均年有效剂量符合国家标准要求,介入和核医学的放射工作人员人均年有效剂量相对较高,应改进和完善工作场所防护措施,同时应加强工业放射工作人员管理监督。Objective To understand the monitoring levels of individual dose to radiation workers in Jiangsu province from 2011 to 2018,and to analyze their changing trends.Methods Through National Individual Dose Registry,the data on the monitoring result of occupational external exposure of radiation workers in our province was collected,and statistical analysis was performed.Results A total of 176134 radiation workers in Jiangsu province were collected from 2011 to 2018.The annual collective effective dose was 58 man·Sv and the average annual effective dose was 0.35 mSv.The average annual effective doses to medical radiation workers for interventional radiology and nuclear medicine were both 0.41 mSv,with significantly higher NRE ratios than others(χ^(2)=219.1,P<0.05).By 2018,the numbers of monitored workers were 25714 for medical radiation,accounting for 81%,with an average annual effective dose of 0.24 mSv,and 6169 for industrial radiation,accounting for 19%,with an average annual effective dose of 0.18 mSv.Conclusions The average annual effective dose to radiation workers in Jiangsu province is in consistency with the relevant national standards.The dose values for radiation workers in interventional and nuclear medicine are relatively high.The protection measures in their workplace should be improved.Meanwhile oversight of radiation protection should be enhanced for individual radiation workers in Jiangsu province.
