摘　　要：通过应用放射源241Am发射出来的软γ射线穿过物质时被吸收的原理,分别进行了食用盐水中食用盐含量的测定和泥沙水中泥沙含量的测定两组实验,取得较好的实验效果,得到泥沙水对γ射线的吸收服从指数衰减规律的结论,并依据理论原理编写C语言测试程序,计算出泥沙测量质量,与配制标准质量进行比较,结果基本一致,误差较小。According to the principle that the soft γ ray launched out in Am-241source is absorbed while crossing the material,two groups of experiments of surveying salt content in salt water and surveying silt content in silt water had been carried on.Thus it made good experiment result.And conclusion that γ ray is absorbed in silt water obeys index weaken rule is obtained.And the C language software was compiled with theory principle in order to calculate the silt quality and the configuration quality made the contrast.The result indicated that basic consistent and the error is small.
