摘　　要：目的了解、分析2015—2019年内蒙古地区医学应用放射工作人员职业外照射个人剂量水平,为放射工作人员健康管理和辐射防护管理提供数据基础和科学依据。方法通过国家个人剂量登记系统采集内蒙古地区医学应用放射工作人员个人剂量监测数据,并进行统计与分析。结果2015—2019年各年度医学应用放射工作人员人均年有效剂量依次为0.72、0.87、0.88、0.71和0.64 mSv。诊断放射学、牙科放射学、核医学、放射治疗、介入放射学和其他应用6种职业类别放射工作人员年有效剂量分布差异具有统计学意义(H=466.56,P<0.05),介入放射学工作人员人均年有效剂量与核医学放射工作人员差异无统计学意义(P>0.05),但高于其余职业类别(Z=19.95、9.87、10.10、12.76,P<0.05)。结论医学应用放射工作人员人均年有效剂量满足国家标准要求。介入放射学和核医学放射工作人员人均年有效剂量相对较高,特别是介入放射学工作人员和放射性药物操作人员,应持续改进和完善相应辐射防护工作场所防护措施。Objective To understand and analyze the levels of individual dose to medical radiation workers from occupational external exposure in Inner Mongolia autonomous region from 2015 to 2019,with a view to provide basic scientific data for workers′health protection and radiation protection management.Methods By using National Individual Dose Registry,the individual dose monitoring result and other related data for medical workers were collected and analyzed.Results The average annual individual doses to medical radiation workers in a time order from 2015 to 2019 were 0.72,0.87,0.88,0.71 and 0.64 mSv,respectively.There were significant differences in the annual effective dose distribution in diagnostic radiology,dental radiology,nuclear medicine,radiotherapy,interventional radiology and other applications(H=466.56,P<0.05).The average annual effective doses to workers in interventional radiology and nuclear medicine had not shown significant difference(P>0.05),but significantly higher than those in other occupational categories(Z=19.95,9.87,10.10,12.76,P<0.05).Conclusions The average annual effective dose to medical radiation workers is in accordance with the relevant national standards.The dose values for the radiation workers involved in interventional radiology and nuclear medicine are relatively high,especially for interventional radiology workers and radioactive drug operators.The protection measures should be further improved in radiation protection workplace.
