Abstract. The mass attenuation coefficients μs of various soil samples collected from different areas in Maharashtra State (India) have been studied by using gamma radiation at energy 0.662 MeV for different soil samples. The results have been presented in a graphical form. The increasing linear nature of graphs of number of particles of radiation counted without absorber (I0) per number of particles of radiation counted with absorber (I) vs. the thickness of absorber are fitted by the least square method. The slope of these graphs gives the value of the linear absorption coefficient. The graph of density of the soil samples vs. the mass attenuation coefficient shows that the mass attenuation coefficient decreases exponentially with increasing density and confirms the interaction of gamma radiations with various soil samples of various components.
