摘　　要：目的了解并分析2015年度我国医学应用放射工作人员职业外照射个人剂量水平,为职业性放射性疾病的预防与控制提供基础数据和科学依据。方法通过"国家卫生计生委放射工作人员职业健康管理系统-外照射个人监测管理子系统"采集我国医学应用放射工作人员职业外照射个人剂量监测结果等相关数据,并进行统计与分析。结果2015年度共采集214 860名医学应用放射工作人员的外照射个人剂量监测结果等相关数据,人均年有效剂量为0.429 mSv。其中,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6类职业类别的人均年剂量分别为0.423、0.326、0.538、0.321、0.542、0.407 mSv。6种职业类别人均年有效剂量差异具有统计学意义(P<0.001),核医学和介入放射学工作人员人均年剂量均显著高于其他职业类别(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。核医学、介入放射工作人员受照剂量相对偏高,应进一步加强相关辐射防护措施、设施等,保护其职业健康。Objective To understand and analyze the individual dose level of occupational exposure of medical radiation workers in China in 2015,and to provide the data and scientific basis for the prevention and control of occupational radioactive disease.Methods By using the ＂Occupational health of Radiation workers management system-external exposure of personal monitoring＂,the individual dose monitoring results and other related data of medical workers were collected and analyzed statistically.Results Altogether,data for 214,860 persons have been collected in 2015.The average annual individual effective dose was 0.429 mSv.The average annual individual dose of diagnostic radiology,dental radiology,nuclear medicine,radiotherapy,interventional radiology and others,six categories of occupational groups were 0.423 mSv,0.326 mSv,0.538 mSv,0.321 mSv,0.542 mSv and 0.407 mSv,respectively.The difference of average annual individual effective dose of six categories of occupational groups was statistically significant（P〈0.001）.The average annual individual dose of nuclear medicine and interventional radiology were significantly higher than those of other occupational categories（P〈0.05）.Conclusion The average annual individual effective dose of radiation workers meets the national standards.The exposure dose of nuclear medicine and interventional radiation workers is relatively high.To protect their occupational health,the relevant radiation protection measures and facilities should be strengthened.
