Abstract

Abstract: In this work, mass attenuation coefficients (µ/ρ), effective atomic number (Zeff ), electron density (Ne ), mean free path (MFP), and half-value layer (HVL) of 20 BaO/SrO‒(x) Bi2 O3 ‒(80‒x) B2 O3 glasses (where x=10, 20, 30, 40, 50 and 60 mol%) were calculated using WinXCom program and MCNP5 code. The obtained (µ/ρ) results using both MCNP5 code and WinXCom program were in good agreement. It is found that the addition of Bi2 O3 leads to increase the Zeff values in both BaO/SrO‒Bi2 O3 ‒B2 O3 glass systems. However, the Zeff values of the BaO‒Bi2 O3 ‒B2 O3 glass system are higher than those of the SrO‒Bi2 O3 ‒B2 O3 glasses. The fast neutrons effective removal cross sections (ΣR ) for 20 SrO‒40 Bi2 O3 ‒40 B2 O3 glass is the highest among all studied glasses. The calculated half-value layer values were compared with different glass systems and it was found that the shielding properties of the selected glasses are comparable or even better than other glass systems such as phosphate glasses. Highlights: γ- and neutron radiation shielding parameters of BaO/SrO-Bi2 O3 -B2 O3 glasses are studied. Mass attenuation coefficients (μ/ρ) are evaluated using the MCNP5 simulation code. (μ/ρ) values evaluated by both MCNP5 code and WinXCom program are matched well. (μ/ρ) and Zeff values are increased with an increase in the Bi2 O3 content. Half-value layer of the studied glasses is compared with different glass systems.
