摘　　要：【目的】对上海市静安区2017—2023年放射工作人员职业性外照射个人剂量监测结果进行分析,评价静安区放射工作人员职业防护状况,为职业健康、放射防护及开展健康教育提供科学参考与支持。【方法】以静安区2017—2023年部分医疗机构工作人员为调查对象,采用热释光个人剂量计监测放射工作人员职业性外照射个人剂量,使用SPSS 20.0软件对连续7年个人监测剂量结果进行统计分析。【结果】2017—2023年静安区放射工作人员的年集体有效剂量为329.53人·mSv,人均年有效剂量为0.17 mSv,个人年有效剂量中位数为0.12 mSv。不同年份个人年有效剂量水平差异有统计学意义(H=277.131,P<0.05);不同级别医疗机构个人年有效剂量水平差异有统计学意义(H=46.097,P<0.05),其中三级医疗机构放射工作人员个人年有效剂量最低,为0.09 mSv,低于一级、二级和未定级医疗机构,差异均有统计学意义(P<0.05);男性个人年有效剂量中位数低于女性,差异有统计学意义(Z=-3.438,P<0.05);不同职业类别放射工作人员的个人年有效剂量水平差异有统计学意义(H=150.727,P<0.05)。核医学放射工作人员个人年有效剂量中位数最高,为0.56mSv。【结论】2017—2023年上海市静安区医疗机构放射工作人员个人剂量保持在较低水平,反映了该区医疗机构工作场所的放射防护措施有效,但是应重点关注核医学和一级医疗机构放射工作人员。[Objective]To analyze the individual monitoring results of the radiation workers in Shanghai’s Jing’an District from 2017 to 2023,to assess the occupational protection status as well as to offer scientific references for enhancing occupational health and radiation safety,and to provide support for health education initiatives targeting radiation workers.[Methods]Radiation workers from several medical institutions in Jing’an District from 2017 to 2023 were selected as the subjects for this study.The individual dose of occupational external radiation exposure was monitored by using thermoluminescence dosimeters.Continuous data of seven years were statistically analyzed using SPSS 20.0.[Results]From 2017 to 2023,the annual collective effective dose for radiation workers in Jing’an District was 329.53 person·mSv,with an average individual annual effective dose of 0.17 mSv,and the median individual annual effective dose was 0.12 mSv.There were statistically significant differences in the individual annual effective doses across different years(H=277.131,P<0.05).The individual doses varied significantly among different levels of medical institutions(H=46.097,P<0.05),with tertiary institutions having the lowest median individual dose of 0.09 mSv,which was significantly lower than those at primary,secondary,and ungraded institutions(P<0.05).The median annual effective dose in males was lower than that in females,showing a statistically significant difference(Z=-3.438,P<0.05).There were significant differences in the individual annual effective doses among different occupational categories(H=150.727,P<0.05),with nuclear medicine workers experiencing the highest median annual dose of 0.56 mSv.[Conclusion]From 2017 to 2023,the individual dose of radiation workers in medical institutions in Jing’an District of Shanghai remained at a low level,reflecting the effective measures of radiation protection facilities in workplaces in Jing’an District,but particular attention should be given to radiological workers in n
