In the paper, the character of gamma-ray spectrometry is studied upon the simplex element medium, granite, gritstone, limestone and basalt. We can use the variable of S1/ S2 to distinguish the effective atom number so we can distinguish the lithology.

在考虑大气扰动因素下，对单一元素介质、花岗岩、石灰岩、砂岩和玄武岩上空γ能谱的分布特征进行研究，结果表明利用S1/S2的方法可以定性判别岩石的有效原子序数，进而区分岩石性质。
