Abstract

The parameter attenuation coefficient usually depends upon the energy of radiations and nature of the material. The variation of linear and mass attenuation coefficient with different soil samples having chemical and Physical properties containing microelements has been investigated, using gamma radiation method. A scientific study of interaction of radiation with matter demands a proper characterization and assessment of penetration and diffusion of gamma rays in the external medium. The study of attenuation coefficient of various materials has been an important part of research in radiation chemistry, Physics, agriculture and human health. The soil sample is placed between collimated gamma source and NaI (Tl) with suitable geometric arrangement. The numbers of counts were counted with and without sample by varying the thickness of the sample. For this work, soil Samples were collected from different locations of Latur district and Osmanabad district from Maharashtra state of India and the parameters attenuation coefficients of soils were determined by performing experiment of gamma irradiation on soil samples. The results are represented in graphical forms. The Experimental measured values of linear and mass attenuation coefficient are in good agreement with standards which validates the gamma absorption law.
