Abstract
This work investigates the radiation shielding properties of MgB2, CrAs0.45Sb0.55, and FeAs polycrystalline alloys synthesized by a conventional solid-state reaction method. The structural properties of the prepared alloys were reported by X-ray diffraction using the Rietveld refinement available in Match 3 software. The densities for the prepared alloys were measured experimentally to explore the radiation shielding properties. The mass attenuation coefficient (MAC) and different radiation shielding were determined using Phy-X software for each studied sample in the energy range of 0.015–15 MeV. The XRD results manifested P 6 2 space group for the MgB2 sample, P 6c 2c for CrAs0.45Sb0.55 sample, and P 2c 2 ab for the FeAs sample. The density values for MgB2, CrAs0.45Sb0.55 and FeAs are 1.9041, 3.9482, and 5.6934 g/cm3. The MAC values at 0.015 are 3.59 cm2/g for MgB2 sample, 44.04 cm2/g for the CrAs0.45Sb0.55 sample, and 80.84 cm2/g for the FeAs sample. The results revealed that the FeAs sample has the best ionizing radiation shielding properties among all investigated samples. These findings suggest that this alloy can be used in ionizing radiation shielding applications.
