Calculation the Nuclear Radiation Absorption Parameters in Pb Alloys

Abstract

In this research, various binary alloys were prepared and studied, consisting of lead as the matrix material, with different weight percentages of bismuth and tin added as enhancing elements. The study focused on evaluating the physical properties of these alloys, specifically their ability to attenuate gamma rays. For this purpose, the mass attenuation coefficient () of the prepared alloys was calculated using the Nist-XCom database, over a wide energy range from 0.05953 to 800(MeV). Based on the calculated mass attenuation coefficient values, a set of other important attenuation parameters were derived, including the linear attenuation coefficient (), molecular cross section (), electron cross section (), effective atomic number (Z_eff), electron density (N_ele), mean free path (), half-layer thickness (HVL), and tenth-layer thickness (TVL). In addition, the K-edge absorption edges of the elements in the studied alloys were determined.
