In glasses with the composition 45P 2 O 5 –45PbO 2 − ( 10 - x ) CdO– x MoO 3 , x = (0 ≤ x  ≤ 5 mol%), melt quenching technique was used to fabricate these samples. The structural characteristics of the proposed glasses were determined using X-ray diffraction. Fabricated glasses were found to have a higher density and refractive index. The spectroscopic characteristics of fabricated glasses were evaluated using UV–VIs. Energy bandgap increases as the content of MoO 3 increases, while Urbach energy decreases. Phy-X/PSD has been used to investigate radiation shielding properties. Mass attenuation coefficient values are positively affected by increases in the MoO 3 ratio. G1 has the maximum half-value layer value, whereas G5 has the minimum. The exposure and energy absorption build-up factor (EBF and EABF) values decreased slightly as the MoO 3 content increased. As a result, among all other glasses, G5 glasses have the best shielding capacity.
