摘要 对龙门山山前断裂带两侧表土中氡活度浓度进行了检测。结果表明,不同地层中,由于铀、钍等放射性元素含量的不同,其土壤中氡浓度也存在着明显的差异;在第四纪地层中,氡活度浓度的变化视表土的干湿程度、空隙度等而论,其变化范围存在很大差异。 The radon concentration in two - side surface soil of Longmen mountain's piedmont fault zone was measured. The result shows that there is a clear difference of radon concentrations in the soil because of the content of radioactive elements such as uranium, thorium and other radioactive elements are different in different strata. In the quaternary strata, radon concentration changes depending on the degree of dry and wet, surface soil porosity and other factors are also concerned. Its range has a big difference.
