2014年许昌市职业外照射个人剂量监测

Personal dose monitoring of occupational exposure in Xuchang city in 2014

目的:掌握许昌市2014年从事放射工作的有关人员接收外照射剂量的水平及相关防护措施情况。方法:对相关人员进行接收放射剂量的测定,根据从事行业,接收放射类型及所从事工种不同等条件进行分类,对结果进行统计、分析。结果:从事医学辐射类的人均年有效剂量平均值(0.083±0.003)m Sv/a,从事工业辐射类的人均年有效剂量平均值(0.096±0.004)m Sv/a。结论:2014年许昌市所有从事放射类相关行业的人员,其机体所接受的放射的剂量均低于国家规定的标准,但从事工业辐射类的人员接触放射剂量相对较高。

Objective:To grasp the level of external exposure dose and relevant protective measures for the relevant persons who are engaged in radiation work in Xuchang in 2014.Methods:We measured the radiation dose to the relevant personnel,according to the industry,the types of received radiation and the different types of jobs,and the results were statistically analyzed.Results:The average annual effective dose for medical radiation was(0.083±0.003)mSv/a,and the average annual effective dose of industrial radiation was(0.096±0.004)mSv/a.Conclusion:The dose of all engaged in the radiation related industries received by the radiation is lower than the national standards in Xuchang city in 2014,but the exposure to radiation dose is relatively high for workers engaged in industrial radiation.
