Novel quaternary glasses with varying compositions of x Bi 2 O 3 -(75- x )TeO 2 - 20Li 2 O-5Al 2 O 3 were synthesized using a melt -quenching method to analyze their physical, elastic properties and to evaluate their potential as radiation shielding materials. The X -Ray Diffraction (XRD), Fourier Transform Infrared (FTIR) and ultrasonic measurement were utilized to study those properties. The radiation shielding properties of the glass samples were determined for 0.01-10000 MeV photon energy range by using Phy-X/PSD software. The incorporation of Bi 2 O 3 , ranging from 0 mol% to 5 mol%, led to an increase in density which is measured by Archimedes' principle, ascending from 4.68 to 5.06 g/cm 3 . The longitudinal, bulk, shear, and Young's modulus, displayed a non-linear decline from 63.41 to 61.44 GPa, 33.52 to 33.20 GPa, 22.41 to 21.18 GPa, and 54.99 to 52.39 GPa. Furthermore, the inclusion of Bi 2 O 3 up to x = 5 mol% produce mass attenuation coefficient (MAC) of 14.892 cm 2 /g at x-ray energy of 40 KeV, surpassing that of commercial RS360 and RS520 radiation shielding glasses by 577% and 323%, respectively. When subjected to gamma ray of 662 KeV the MAC is 0.08 cm 2 /g which was also accompanied by a reduction in the half -value layer (HVL) to 1.58 cm where it surpassed the concrete by 38% and linear attenuation coefficient (LAC) of 0.38 cm - 1 . The effective atomic number (Z eff ) and effective electron density (N eff ) reach maximum value of 59.74 and 7.88 x 10 23 electrons/g at 0.02 MeV respectively. These results highlight the suitability of the glass composition with x = 5 mol% as an exceptional choice for employment as to shield against both X-rays and gamma rays.
