目的了解无锡市放射工作人员受照剂量水平,为辐射防护提供依据。方法采用热释光剂量测量方法对无锡市2008～2010年放射工作人员进行监测,并对结果进行统计分析。结果三年总集体有效剂量为2 209.35man mSv。年人均有效剂量1.70mSv.a-1,99%以上放射工作人员人年剂量小于5mSv。结论无锡市大部分放射工作人员个人人均年有效剂量符合国家标准,同时应重视卫生院与社区卫生服务中心放射工作人员高剂量的情况。
Objective To understand the dose level of radiation workers in Wuxi and provide the basis for radiation protection. Methods The dosage of thermoluminescence was used to monitor the radiation workers in Wuxi from 2008 to 2010, and the results were statistically analyzed. Results The three-year total collective effective dose was 2 209.35man mSv. Annual per capita effective dose 1.70mSv.a-1,99% of the annual dose of radiation workers is less than 5mSv. Conclusion The annual per capita effective dose of most radiological workers in Wuxi meets the national standards, and the radiation dose of health workers in community hospitals and community health centers should be emphasized.
