目的了解卢湾区2009年至2011年不同工种放射工作人员所受外照射剂量水平,为加强放射防护的科学管理提供数据。方法按GBZ 128-2002《职业性外照射个人监测规范》的要求,采用热释光个人剂量监测。结果 2009年至2011年卢湾区放射工作人员人均年剂量为0.36mSv。不同工种放射工作人员中介入放射学所受剂量水平最高为0.75 mSv;牙科放射学最低仅为0.11 mSv。结论卢湾区放射工作人员的工作环境是安全的。对介入放射工作人员的管理仍是个人剂量监测工作的重中之重。
Objective To understand the external exposure dose of radiation workers of different types from 2009 to 2011 in Luwan District and provide data for strengthening the scientific management of radiation protection. Methods According to the requirements of GBZ 128-2002 “Personal monitoring of occupational external radiation”, personal dose monitoring with thermoluminescence was used. Results The per capita annual dose of radiation workers in Luwan District from 2009 to 2011 was 0.36mSv. Radiation workers in different types of interventional radiology receive the highest dose level 0.75 mSv; dental radiology minimum is only 0.11 mSv. Conclusion Luwan District radiation staff working environment is safe. The management of interventional radiation workers remains the top priority of individual dose monitoring.
