土壤中的氡气（Rn）是研究断裂的一个有效手段,通过氡浓度变化曲线可以大致确定断裂带的位置、范围和产状等。一般而言,断裂带上方呈现Rn峰值异常,远离断裂带逐渐衰减至正常水平。土壤中氡浓度变化取决于断裂的规模、倾角、岩性、破碎带宽度、充填物透气性、覆盖层、地下水、稀释效应和放射性平衡等因素。

Many studies have shown that Radon in soil gas is an effective method in the research of fracture like as a tracer.The location of fracture,scope,occurrence,etc can be roughly determined by the variational curve of radon concentration.Generally speaking,the fault plane shows the peak radon anomalies,then it gradually decays to normal level away from fracture zone.Abnormal types of the variational curve of radon concentration could be rather complex,and depend on the fracture scale,angle,lithology,broken width,filling permeability,cover,groundwater,dilution effects and radioactive equilibrium and other factors.
