concentration, whereas molar volume decreased. Additionally, the ranges of longitudinal and shear velocities are 4730 to 5085 m/s and 2685–2895 m/s, respectively. The elastic moduli for longitudinal range between 71.9–154.3 GPa, shear range between 23.2–50 GPa, bulk range between 23.2–50 GPa, and Young’s range between 58.5–126 GPa, respectively. The study employed Phy-X/PSD code to examine the radiation attenuation behaviour of magnesium beryllia-borosilicate, also known as (BMBSLa) glasses, at varying concentrations of La

. We examined the relationship among the half value layer (HVL) and density. HVL values at a density of 3.213 g/cm

range from 0.0087 to 11.746 cm and at density of 5.967 g/cm

range from 0.02 to 5.727 cm at (0.015–15 MeV). Tenth value layer (TVL) and mean free path (MFP) are evaluation and comparison between HVL, TVL and MFP for the same glass at specific energy were also conducted. The glass samples under investigation are excellent candidates for usage in the field of shielding radiation because they are more transparent.
