摘要
本文报道北京市从事125I标记的工作人员和各类型医院从事核医学的放射工作人员的内照射个人监测及剂量估算方法和结果。共监测了28个单位的231人,其中,从事核医学的放射工作人员152人,从事125I标记的79人。监测结果表明,受到内污染者共138人,占总监测人数的59.7%;受到污染的138名放射性工作人员的年个人待积有效剂量当量在2.2×10-3~2.2mSv范围内;被监测的全体人员的集体待积有效剂量当量为2.2×10-2人·Sv;人均待积有效剂量当量为9.5×10-2mSv;被监测的全部放射工作人员年待积有效剂量当量均在2.2mSv以下。
The methods, and results of internal individual dose monitoring of radiation workers in Beijing are reported in this paper. 213 workers in 28 laboratories have been monitored, of which 138 workers presented a significant internal contamination. Personal annual committed effective dose equivalent is within the range of 2.2×10 -3 mSv~2.2 mSv for the 138 contaminated workers. Collective committed effective dose equivalent is 2.2×10 -2 man·Sv and the per capita annual committed effective dose equivalent is 9.5×10 -2 mSv for the 231 workers. (
