摘　　要：目的分析宝鸡市医疗机构放射工作人员外照射剂量水平及变化趋势,为宝鸡市放射工作人员的职业健康管理提供参考依据。方法采用热释光剂量仪监测放射工作人员职业性外照射个人剂量,并对2013—2022年数据进行分析。结果2013—2022年宝鸡市疾病预防控制(疾控)中心共监测医疗机构放射工作人员2834人,有效监测2384人,不同年份有效检测率比较,差异有统计学意义(P<0.05)。92.2%的放射工作人员年有效剂量<1.0 mSv,人均年有效剂量范围为0.22~0.79 mSv,10~<20年和20~<30年放射工龄组人均年有效剂量高于<10年工龄组。不同年份、工种、级别医院的放射工作人员人均年有效剂量比较,差异均有统计学意义(均P<0.05)。核医学工作人员人均年有效剂量最高(0.81 mSv),其次是放射放疗(0.52 mSv)和放射诊断学工作人员(0.50 mSv);一级及未定级医疗机构放射人员人均年有效剂量高于二级和三级医疗机构。结论2013—2022年宝鸡市医疗机构放射工作人员有效检测率逐年提高,放射工作人员个人剂量处于较低水平,人均年有效剂量呈下降趋势。重点关注核医学工作人员、一级及未定级医疗机构和放射工龄10~<30年的放射人员的健康状况、并针对性开展放射防护教育。Objective To analyze the level and change trend of external radiation dose of radiation workers in medical institutions in Baoji City,provide reference for occupational health management of radiation workers in Baoji City.Methods The individual dose of occupational external exposure of radiation workers was monitored by thermoluminescence dosimeter and the data from 2013 to 2022 were analyzed.Results From 2013 to 2022,Baoji Center for Disease Control and Prevention monitored 2834 adiological workers in medical institutions,and effectively monitored 2384 people,and the the difference in the effective detection rate was statistically significant among different years(P<0.05).92.2%radiological workers had the annual effective dose<1.0 mSv,and the annual effective dose per capita was between 0.22 and 0.79 mSv.The average annual effective dose per capita in 10-<20 and 20-<30 years of working group was higher than that in<10 years of working group.The differences in the per capita annual effective dose were statistically significant among radiological workers in different years,different types of work and different level of hospitals(all P<0.05).The nuclear medicine workers had the highest annual effective dose per capita(0.81 mSv),followed by radiotherapy workers(0.52 mSv)and diagnostic radiology workers(0.50 mSv).The per capita annual effective dose of radiological workers in gradeⅠand unrated medical institutions was higher than that in gradeⅡandⅢmedical institutions.Conclusions The effective detection rate of radiation workers in medical institutions in Baoji City from 2013 to 2022 has increased year by year,the individual dose of radiation workers is at a low level,and the annual effective dose per capita shows a downward trend.It is necessary to focus on the health status of nuclear medicine workers,medicine workers in gradeⅠand unrated medical institutions,and medicine workers with 10-30 years of radiological service,and carry out targeted education on radiological protection.
