摘　　要：江西作为石煤资源储量大省,石煤矿的开发与综合利用对环境造成的影响较突出。通过对江西上饶县八都石煤矿区环境天然γ辐射空气吸收剂量率的调查,测量结果表明:区内γ辐射空气吸收剂量率变化范围为47. 2~1151. 1 n Gy/h,平均值为124 n Gy/h,分别是全国、江西省、上饶地区背景值的1. 97、1. 69、1. 78倍。其中下寒武统荷塘组的均值最高为408. 6 n Gy/h,超过江西省及上饶地区背景值的5倍。石煤矿的开发导致区内γ辐射水平有明显的升高。γ辐射水平分布特征主要受控于地质体的分布,高值区集中于赋石煤岩层荷塘组。As a province with large reserves of stone coal resources,Jiangxi has a significant impact on the environment due to the development and comprehensive utilization of stone coal mines.Through the investigation of the natural gamma radiation dose rate in the Badu stone coal mine area of Shangrao County,Jiangxi Province,the measurement results show that the gamma radiation dose rate varies from 47.2 to 1151.1 n Gy/h,with an average of 124 n Gy/h which is 1.97,1.69 and 1.78 times the background values of China,Jiangxi province and Shangrao city respectively.The mean value of the lower Cambrian Hetang formation is 408.6 n Gy/h,which is more than 5 times that of the Jiangxi Province and Shangrao City.The exploitation of the stone coal mine has caused a significant increase in the level of gamma radiation in this area.The distribution of gamma radiation levels is mainly controlled by the distribution of geological bodies,and the high value areas are concentrated in the Hetang formation which contains the stone coal stratum.
