核工业系统职业性照射个人剂量监测(1991～2000)

INDIVIDUAL DOSE MONITORING OF OCCUPATIONAL EXPOSURE IN NUCLEAR INDUSTRY SYSTEM (1991～2000)

本文介绍了中国核工业系统1 991～2 0 0 0年职业性照射个人剂量监测情况和主要结果。这1 0年中,除铀矿冶系统以外的核工业职业性照射的被监测总人年数为49899,工作人员所受外照射集体有效剂量为98.48人·Sv ,年人均有效剂量为1 .97mSv。内照射个人剂量监测结果表明,各有关厂、院的年人均待积有效剂量均低于5mSv。还简要介绍了铀矿山、水冶厂个别年份的职业性照射个人剂量监测结果。最后对核工业系统个人剂量监测结果做了初步评价。

The summary and main results of individual dose monitoring (1990～2000) from occupational exposure in China Nuclear Industry System are presented in this paper. During ten years, the external collective effective dose to workers in seven plants (not uranium mines and processing mills) and institutes is 98.48 person·Sv, the per capita effective dose is 1.97 mSv.The general situation for individual dose monitoring from internal exposure is also introduced. The annual average committed effective dose is less than 5.0 mSv. The individual dose monitoring results (1991～1992) for occupational exposure from Uranium mines and processing mills are depicted.In the end,the individual dose monitoring data in nuclear industry system are preliminarily analysed.
