Abstract
This study examined the impact of substituting Li2O with Bi2O3 on the mechanical and radiation shielding capabilities of the Li2O-Bi2O3-CdO-B2O3 glass system. The glasses' Young's (E), bulk (K), shear (S), and Poisson's ratio (ϑ) were computed using Makishima and Mackenzie's known formulae. The ENDF/B-VIII EPICS2017 collection was used to calculate the photon cross section, linear attenuation coefficient (LAC), mass attenuation coefficient (MAC), half-value layer (HVL), mean free path (MFP), and effective atomic number (Zeff) of the sample glasses for photon energies ranging from 122 to 1333 keV. The EPICS2017 was generated using the EpiXS interpolation software. With the addition of Bi2O3, E dropped from 84 to 37 GPa, whereas K dropped from 66 to 20 GPa. With Bi2O3 content, S showed a similar pattern, dropping from 33 to 15 GPa., similar to the E, K, and S trends. The sample glass cross sections are large at lower energies, but as the photon energy increases, they get smaller. As the Bi2O3 is replaced with Li2O oxide, the cross sections decrease. For low energies, the sample glass's MAC and LAC are significant, but as photon energy increases, they become smaller. The sample glasses are more likely to shield lower-energy rays. The gap between its atoms is the closest in Li0 glass, which has the greatest density of the five glass samples. As a result, it has the greatest number of photon interactions and the shortest mean free path. Li0 has the thinnest HVL since MFP is directly related to it.
