铀矿勘探工作人员年有效剂量当量的估算

Estimation on Annual Effective Dose Equivalent for Whole-body Exposed Staff in Uranium Exploration

γ测井仪或物探编录仪野外核查常用的6号或5号226 Ra源及密度测井时所挂137 Cs源发出的核辐射无色无味,若不注意防护会对人体造成伤害。文章介绍了铀矿勘查中放射源γ射线对人的辐射有效剂量当量的估算,为工作人员的安全防护提供指导和参考。

Nuclear radiation from 226Ra radiation sources No. 6 or No. 5 used in 7 logging probe or geo- physical documentation instrument and 137 Cs radiation sources used at density logging may cause harm to the human body without protection. This article systematically introduces the estimation of nuclear radia- tion of 7 radiation sources personal effective dose equivalent to whole body exposed staff in uranium ex- ploration, which will provide a guidance to the radiation protection for the staff. Key words~ uranium; exploration; effective dose; dose equivalent
