目的调查2011年江西省医院放射工作人员不同工种的外照射个人剂量水平。方法依据GBZ128-2002《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监测。结果江西省2011年医院放射工作人员个人剂量监测的周期依从性合格率仅为77.05%;总集体年有效剂量为1.061人.Sv,人均年有效剂量值为0.534 mSv,99.35%的医院放射工作人员年剂量低于5 mSv。结论江西省医院放射工作人员个人剂量监测的周期依从性有待进一步提高;年有效剂量均低于国家标准限值,符合安全标准[1]。
Objective To investigate the personal radiation dose levels of different types of radiation workers in Jiangxi Provincial Hospital in 2011. Methods According to the requirements of GBZ128-2002, “Occupational exposure to external personal monitoring standards”, the dosage of thermoluminescence was used to monitor the dose of external exposure. Results The compliance rate of periodic compliance of individual dose monitoring for radiation workers in Jiangxi Province in 2011 was only 77.05%, the total effective dose for the collective was 1.061, the annual effective dose per capita was 0.534 mSv, and 99.35% of the hospital radiologists The annual dose is less than 5 mSv. Conclusion The periodic compliance of individual dose monitoring for radiation workers in Jiangxi Provincial Hospital needs to be further improved. The annual effective dose is below the national standard limits and meets the safety standards [1].
