2010年江苏省部分放射工作人员个人剂量监测结果

Individual dose monitoring results of some radiation workers in Jiangsu Province in 2010

目的掌握江苏省省管单位3 273名放射工作人员2010年外照射个人剂量水平及分布情况。方法以2010年3 273名放射工作人员外照射个人剂量值为研究对象,按照《职业性外照射个人监测规范》GBZ 128-2002的要求,采用热释光方法监测放射工作人员外照射剂量当量Hp(10)。结果 3 273名放射工作人员的年有效剂量均低于5 mSv,其中95.0%的放射工作人员年有效剂量低于1 mSv;放射工作人员的年平均有效剂量为0.243 mSv。结论江苏省省管放射工作人员的放射防护条件良好,其中,医疗照射的放射工作人员防护更值得重视。

[ Objective]To understand the individual dose level of external exposure to radiation and distribution of 3 273 radiation workers from Jiangsu Province control units in 2010. [ Methods] Taking 3 273 radiation workers＇ individual dose level of extemaI exposure to radiation in 2010 as study object, according to requirement of ＂Occupational Monitoring Norms of Individual Dose Level of External Exposure＂, thermoluminescence was adopted to monitor external exposure dose equivalent Hp （ 10） of radiation work- ers. [ Results] The annual effective dose of 3 273 radiation workers was lower than 5 mSv, and 95% workers＇ effective dose was lower than 1 mSv,. The annual effective dose of radiation workers was 0.243 mSv. [ Conclusion] Radiological protection conditions for radiation workers is good in Jiangsu Province. The protection of medical radiation workers is more worthy of attention.
