INFLUENCE OF BORON ON GAMMA-RAY SHIELDING EFFICIENCY OF CLAY MATERIAL‏

Abstract

"In the present study, the gamma radiation shielding capability of clay as well as doped by boron was systematically investigated involving the measurement of linear attenuation coefficient and subsequently determination of shielding parameters at energy of 0.662 MeV for 137Cs. These include mass attenuation coefficient, mean free path, half layer value, tenth layer value, effective atomic number and electron density. In particular, it was noticeably found that increasing the prepared samples thickness leaded to higher values of mass attenuation coefficient (0.1065 cm2 g-1). Furthermore, samples treated with boron showed considerably higher mass attenuation coefficient values. In the free mean path, half layer values and tenth layer value profiles, the prepared materials showed an increased trend in conjunction with the thickness profile. The present work presents a new approach towards available, eco-friendly, cost-effective and efficient gamma radiation shielding materials"
