Compositional Impact of Cerium Oxide on the Gamma Radiation Shielding Properties of Bismuth-Boro-Tellurite Glass

Gamma radiation is prevalent in various industrial, medical, and research applications. Developing glass materials that provide effective shielding can contribute to safer environments for workers and the public exposed to radiation. The objective of this research is to explore how the incorporation of cerium oxide into the bismuth-boro-tellurite glass system influences its effectiveness in shielding gamma radiation. Glass samples, characterized by the chemical composition {[(TeO2)0.7(B2O3)0.3]0.75(Bi2O3)0.25}1-y(CeO2)y, were fabricated using the melt quenching technique. Lead equivalent thickness (LET) measurement has been used to determine the linear attenuation coefficients for gamma ray photon energy of 662 keV. The mass attenuation coefficients (MAC), mean free path (MFP), half-value layer (HVL), and effective atomic number were calculated using these coefficients. The 25BiBTe glass with the highest amount of cerium was found to have the highest MAC values and exhibit superior HVL and MFP values compared to several common radiation shielding materials and ordinary concrete.
