重庆地区煤矸石放射性分析

Analysis of the radioactive of gangues in Chongqing area

依据重庆市2007年伴生放射性矿物调查,对重庆地区煤矸石表面γ照射量率和天然放射性核素含量进行调查研究,初步分析了矸石与煤的放射性核素含量的相关性,在此基础上评价了重庆市矸石放射性对建筑材料生产的影响。

Based on the survey of minerals associated with radionuclides in 2007 in Chongqing,this paper describes the survey results of natural radionuclide concentrations and γ radiation dosage on gangue in Chongqing area.The correlation between natural radionuclide concentrations of gangue and coal is primarily analyzed.The evaluation for the effect of gangue natural radionuclide to building materials is proposed in this paper too.
