| 摘 要： | 本文介绍了四川原煤及其废渣与制品的γ辐射剂量率、附加γ辐射人均年有效剂量量。同时,用低本底Ge(Li)多道γ能谱仪测定了原煤、矸粉与矸砖,煤渣与煤渣砖、粉煤灰及粘土砖等样品中的天然放射性核素~(238)U,~(232)Th,~(226)Ra,~(40)K的比活度。经比较和研究,找出了这些物质的放射性水平及它们彼此之间的规律。

| Abstract: | The gamma radioactivity dose-rates of mine-run coal, its Spent ersidues and manufactured articles in Sichuan are reported. The natural radionuclide specific activities of natural radionuclide of ~(238)U, ~(232)Th, ~(220)Ra and ~(40)K in samples of mine-runck were measucoal,coal gangue, powdered coal dust and clay brired by low-background Ge(Li) gamma spectrometer. The radioactivity levels of these materials and their relations vre found. |
