Abstract
The research has examined the structure, elasticity, and various radiation shielding properties of a bismuth cadmium borate glass system containing samarium ions using empirical methods. The glass density ( D glass ) was experimentally measured by Archimedes’ principles. When 4 mol% of samarium oxide (Sm 2 O 3 ) was introduced to the host glass, the density of the base (free Sm 2 O 3 ) sample dropped from 5.597 g cm −3 to 5.468 g cm −3 . The Makishima-Mackenzie (M–M) model was used to compute the elastic parameters, including Young’s ( E ), shear ( S ), and bulk ( B ) moduli. These parameters increased from 37.009 to 38.003 GPa, from 14.908 to 15.317 GPa, and from 23.827 to 24.410 GPa, respectively. Exposing the base sample to 8.04 keV yielded a mass attenuation coefficient ( MAC ) of 178.048 cm 2 g −1 . Adding 4 mol% Sm 2 O 3 to glass increased its MAC to 188.797 cm 2 g −1 . If the glass thickness is increased to 3 cm, the high radiation energy of 2.506 MeV can be reduced to half its value ( HVL ). The effective atomic number ( Z eff ) for the base sample at 19.63 keV was 77.957, decreasing to 27.071 at 661.7 keV. A similar trend was observed for all other glass samples. Such calculations reveal a promise in radiation shielding protection.
