摘　　要：本文介绍了核工业系统职业性照射个人剂量监测(1985—1990年)的概况和主要结果。统计结果表明,核工业各厂、院、所等单位放射性工作人员1985—1990年的外照射年集体剂量当量分别为29.88、26.95、19.16、14.26、9.08和9.22人·Sv;年人均剂量当量分别为4.98、4.66、3.65、2.79、2.40和2.27 mSv。对内照射个人剂量监测情况进行了简要介绍,给出了部分单位铀、钚、氚等核素的内照射剂量监测数据,各有关厂、院的年人均待积有效剂量当量均低于5.0 mSv。还概述了铀矿山职业性照射个人剂量监测结果。最后,对个人剂量监测数据作了初步的评价分析。The summary and main results of individual dose monitoring(1985—1990)fromoccupational exposure in nuclear industry are presented in this paper.The statistical resultsshow that the annual collective dose equivalent from external exposure to workers in sixplants and institutes in 1985—1990 are 29.88,26.95,19.16,14.26,9.08 and 9.22man·Sv,respectively.The annual average dose equivalent are 4.98,4.66,3.65,2.79,2.40 and 2.27 mSv,respectively.The general situation for individual dose monitoring from in-ternal exposure is briefly introduced.The internal exposure dose from Uranium,plutoniumand Tritium in some facilities are given.The annual average committed effective dose equiv-alanet are less than 5.0 mSv.The individual dose monitoring results for occupational expo-sure from Uranium Mining are depicted.The individual dose monitoring data are analysedpreliminarily.
