目的掌握江苏省省管单位3000多名放射工作人员2009-2011年外照射个人剂量水平及分布情况。方法以2009-2011年我所检测的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H p(10)。结果 2009-2011年我所监测的放射工作人员的年有效剂量均低于5 mSv,其中超过95%的放射工作人员年有效剂量低于1 mSv;2009-2011年放射工作人员的年平均有效剂量分别为0.192 mSv,0.241mSv和0.180 mSv。
Objective To understand the level and distribution of personal radiation dose of more than 3,000 radiation workers in Jiangsu Province from 2009 to 2011. Methods According to the personal exposure dose of radiation workers tested in 2009-2011, the method of thermoluminescence was used to monitor the external radiation of radiation workers according to the requirements of GBZ 128-2002 of “Personal Monitoring Regulations for Occupational Exposed Personals” The dose equivalent H p (10). Results The annual effective doses of the radiation workers I monitored were less than 5 mSv between 2009 and 2011, with more than 95% of the effective doses of radios workers below 1 mSv; the annual average effective dose of radiation workers in 2009-2011 0.192 mSv, 0.241 mSv and 0.180 mSv, respectively.
