The study presents a ternary glass series fabricated as a mixture of 60B2O3-(40-x)BaO-xBi2O3, x = 0, 2.5, and 5 wt%. The glass density was measured using the Archimedes method with Xylene as an immerse liquid. The fabricated glass samples' mechanical features and elastic moduli were evaluated utilizing the Makishima-Makenzie (M-M) model based on the fabricated glass chemical composition and density. The elastic moduli were varied in the range between 92.862 and 99.734, 71.142–81.750, 36.208–38.457, and 119.420–133.027 Gpa for Young, bulk, shear, and longitudinal moduli. Other mechanical properties like Poisson ratio, microhardness, fractal bond conductivity, and softening temperature were predicted based on the fabricated glass samples' elastic moduli. Moreover, experimental measurements were applied to evaluate the linear attenuation coefficient at energies 662, 1173, and 1332 keV. The experimental measurements were confirmed with the theoretical XCOM program. Monte Carlo N- particle transport code version 5, XCOM, and BXCOM programs were used to evaluate the fabricated glass samples' radiation shielding properties. •Four Bismuth abased barium borate were fabricated using the melt quenching method.•Samples density increased from 3.15 to 3.28 g/cm3 with raising the Bi2O3 ratio.•The elastic moduli predicted based on the Makishima-Mackenzie model.•The elastic moduli increased with the Gt while they decreased with the Vi values.•Glasses' shielding properties were enhanced with the BaO replacement.
