目的对广东省核电站维修人员2006~2007年的个人剂量监测资料进行总结分析。方法用LiF(Mg,Cu,P)热释光剂量计对核电站维修人员进行个人剂量监测。结果两年共监测1 686人次,受照剂量小于5mSv的人员占总监测人数的93.6%,实测集体剂量当量2.83人.Sv,人均年剂量1.68mSv,没有人员受照剂量超过国家标准限值。结论核电站维修人员由于其工作环境的特殊性应成为防护与监测的重点对象。
Objective To summarize the personal dose monitoring data of maintenance personnel of nuclear power stations in Guangdong Province from 2006 to 2007. Methods LiF (Mg, Cu, P) thermoluminescence dosimeters were used to monitor the personal dose of maintenance personnel in nuclear power stations. Results A total of 1 686 people were monitored during the two years, 93.6% of the total number of people undergoing radiation exposure was less than 5mSv, the measured total dose equivalent was 2.83 persons, the average annual dose of Sv was 1.68mSv, and no dose of personnel exceeded the national standard limit. Conclusions Nuclear power station maintenance personnel should be the focus of protection and monitoring due to the special nature of their work environment.
