Study of photon attenuation coefficient of soil samples from Maharashtra and Karnataka states (India) at gamma ray energies from 122 keV to 1330 keV

摘要

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 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. For this work, Soil Samples were collected from different regions of Maharashtra and Karnataka states of India and the parameters attenuation coefficients of soils were determined by performing experiment of gamma radiation on soil samples. The result represented in graphical forms. The Experimental measured values are in good agreement which validates the gamma absorption law.
