本工作采用低本底Ge(Li)γ谱仪、低本底HPGeγ谱仪,对来自我国24个省(自治区)91个(矿)矿务局的862个煤矸石样品中天然放射性核素含量进行了测定,并对煤矸石综合利用的辐射影响进行了评价,主要结果如下:(1)煤矸石样品中~(226)Ra,~(232)Th和~(40)K含量的频率分布介于正态分布和对数
In this work, we used low background Ge (Li) γ spectrometer and low background HPGe γ spectrometer to analyze the content of natural radionuclides in 862 coal gangue samples from 91 (mine) mining bureau of 24 provinces (autonomous regions) The main results are as follows: (1) The frequency distribution of ~ (226) Ra, ~ (232) Th and ~ (40) K in gangue samples Normal distribution and logarithm
