目的掌握上海市黄浦区医疗卫生机构2007～2011年放射诊疗工作人员外照射个人剂量水平。方法采用热释光剂量方法对放射工作人员进行外照射剂量监测,统计并转换为年有效剂量进行分析。结果以年为周期5年共监测1 933人次,人均年有效剂量为0.953 mSv,从事X射线影像诊断和介入放射学的工作人员人均年有效剂量分别为0.858 mSv以及1.478 mSv;三级医院人均年有效剂量最高。结论本区放射工作人员个人外照射剂量水平在安全范围之内,介入治疗放射工作人员是今后管理的重点。
Objective To grasp the individual dose level of radiation exposure staff from 2007 to 2011 in Huangpu District Health Care Institution in Shanghai. Methods The dosage of thermoluminescence was used to monitor the external radiation dose of radiation workers, and the data were analyzed and converted into annual effective dose. Results A total of 1 933 person-times were observed during the five-year annual cycle with an average annual effective dose of 0.953 mSv. The annual average effective doses of X-ray imaging and interventional radiology staff were 0.858 mSv and 1.478 mSv, respectively. The highest effective dose. Conclusion The individual radiation dose level of radiation workers in this area is within the safe range. Interventional radiation workers are the focus of future management.
