Summary: Glasses with different BaO content in the formulation 15TiO2-70P2O5-(15-x)Li2O-xBaO (0 < x < 10 mol. %) were fabricated using the melt quenching procedure.

BaO content was found to be the only factor affecting the radiation shielding phenomenon in the glasses. BaO reinforcement not only increased the density of the glass compositions, but also enhanced their mechanical and gamma-ray shielding properties.
