摘　　要：目的了解武汉市放射工作人员职业性外照射个人剂量监测情况,分析剂量变化趋势,为放射工作人员辐射防护管理提供科学依据。方法通过方便抽样方法,从国家个人剂量登记系统采集2017-2021年武汉市放射工作人员职业性外照射个人剂量监测资料,分析不同年份、不同职业类别、不同等级医院外照射个人剂量水平。结果此次共调查9134人,人均年有效剂量为0.20 mSv/a。2017-2021年人均年有效剂量总体呈下降趋势(P<0.001)。医学应用人均年有效剂量高于工业应用(0.22 mSv vs 0.14 mSv;P<0.001)。医学应用中诊断放射学工作人员人均年有效剂量最高(0.27 mSv),工业应用中工业辐照工作人员人均年有效剂量最高(0.29 mSv)。个人年有效剂量超过1mSv人员分布比中介入放射学和工业探伤人员所占比例较高(4.90%和1.90%)。一级及未评级医院人均年有效剂量较高(0.35 mSv)。结论武汉市放射工作人员人均年有效剂量逐年下降,未超过国家规定的标准限值(20 mSv)。对个人年有效剂量超过1mSv的介入放射学和工业探伤人员仍需重点关注,同时加强对基层医疗机构和工业放射的监督力度。Objective To understand the individual dose monitoring of occupational external exposure for radiation workers in Wuhan City and analyze the dose change trend,and to provide a scientific basis for radiation protection management of radiation workers.Methods The data on the monitoring results of occupational external exposure of radiation workers in Wuhan City from 2017 to 2021 were collected through the National Personal Dose Registration System,and the individual dose levels of different years,different occupational categories,and different levels of hospitals were analyzed.Results A total of 9134 radiation workers were investigated,with an average annual effective dose per capita of 0.20 mSv/a.The overall personal annual effective dose from 2017 to 2021 showed a decreasing trend(P<0.001).The per capita annual effective dose in medical applications was higher than that in industrial applications(0.22 mSv vs 0.14 mSv;P<0.001).Among medical applications,diagnostic radiologists had the highest average annual effective dose(0.27 mSv),and among industrial applications,industrial irradiators had the highest average annual effective dose(0.29 mSv).The proportion of personnel with personal annual effective doses exceeding 1 mSv was higher in interventional radiology and industrial nondestructive testing(4.90%and 1.90%).The annual effective dose per capita in Class I and unrated hospitals was higher(0.35 mSv).Conclusion The average annual effective dose of radiation workers in Wuhan City has decreased year by year and has not exceeded the national standard limit(20 mSv).Radiation protection management still needs to focus on personnel with personal annual effective doses exceeding 1mSv in interventional radiology and industrial nondestructive testing,and supervision over primary healthcare institutions and industrial radiation should be strengthened.
