This work intends to assess the gamma-ray shielding performance of newly fabricated glasses with diversified content of PbO and B2O3, as well as compare the results with those of previously reported glasses from different authors. The outcome of this work exposed that, the Half Value Layer (HVL) of glass samples Pb45B35, Pb40B40, Pb35B45, and Pb30B50 were determined in order to ascertain the radiation attenuating ability. Comparatively, our fabricated glass samples Pb45B35 (0.50 cm), Pb40B40 (0.55 cm), and Pb35B45 (0.62 cm) had lower values of the HVL than glass samples reported in previous studies where Pb45B35 exhibited the superior performance in terms of gamma ray shielding, resulting from the presence of high content of PbO which advances the power of attenuation of the sample. The results showed that our glass samples outperformed all other previously reported glasses used in comparison in terms of gamma ray protection ability.
