Abstract

The variation of absorption coefficient with different soil samples of various chemical compositions and physical properties has been investigated, using gamma radiation method. For this work, soil Samples were collected from different locations of Nanded and Latur district from Maharastra and Bidar district from Karnataka states of India and Photon absorption coefficients of soils were determined by performing experiment of gamma irradiation on soil samples. The ratio of transmission intensity (I/I) is found to increase as the thickness of soil increases. The linear and mass attenuation coefficients due to soil density are as shown graphically. Graphs of energy in keV v/s mass attenuation coefficient due in cm2/gm to various soil densities are plotted, exponential decay observed. Mass attenuation coefficient depends on soil compositions and its physical properties.
