目的 估算非铀矿山工作人员经由矿石样品外照射途径所致γ外照射年有效剂量.方法 现场采集非铀矿山矿工工作场所矿石样品,利用γ能谱仪测量矿石样品中放射性核素活度浓度,进而估算采矿工作场所矿工所受年有效剂量.结果 在全国7个省区13个矿区共采集、分析了32个矿石样品,其中有2种矿石活度浓度较高,所致矿工的年有效剂量超过1 mSv.结论 γ能谱测量分析方法可以较好地应用于非铀矿山矿石放射性核素分析,其结果可用来估算矿工所受的γ外照射剂量.

Objective To estimate the dose to non-uranium miners from external exposure.Methods Ore samples of non-uranium mines were collected in site and analyzed with gamma spcetrometry,then annual dose to the miners was estimated based on the measured radioactivities of radionuclides.Results Thirty-two ore samples in thirteen mines in seven provinces were collected and analyzed.Among them,radioactivity concentrations in two samples were higher than others,and the annual doses from external exposure to the radionuclides in the two ore samples were estimated to be higher than 1 mSv/a.Conclusions Gamma spectrometry is fit for determining the radionuclides concentrations and its results can be used for estimating dose from external exposure in non-uranium mines.
