目的调查2012年江西省部分医院不同工种放射工作人员的外照射个人剂量水平。方法根据GBZ 128-2002《职业性外照射个人监测规范》的要求,采用热释光剂量方法对个人外照射剂量进行检测。结果江西省2012年医院放射工作人员剂量监测的合格率为86.93%,人均年有效剂量值为0.366 m Sv,98.23%的医院放射工作人员年剂量低于2 m Sv。结论江西省医院放射工作人员个人剂量监测率有待进一步提高;年有效剂量均低于国家标准限值,符合放射卫生防护标准。
Objective To investigate the personal exposure dose of radiographers in different types of work in some hospitals in Jiangxi Province in 2012. Methods According to the requirements of GBZ 128-2002 “Occupational Exposure to External Personal Monitoring Standards”, the dosage of thermoluminescence was used to measure the dose of external exposure. Results In 2012, the qualified rate of dose monitoring for radiation workers in hospitals in Jiangxi Province was 86.93%. The annual average effective dose per person was 0.366 m Sv. The annual dose of 98.23% of hospital radiologists was less than 2 m Sv. Conclusion The monitoring rate of personal dose of radiation workers in Jiangxi Provincial Hospital needs to be further improved. The annual effective dose is lower than the national standard limits and meets the standards of radiation protection.
