Mechanical moduli, such as Young’s modulus (E), Bulks modulus (B), Shear modulus (S), longitudinalmodulus (L), Poisson’s ratio (s) and micro Hardness (H) were theoretically calculated for (100-x)TeO2þxMgO glasses, where x ¼ 10, 20, 30, 40 and 45 mol%, based on the MakishimaeMackenzie model. Theestimated results showed that the mechanical moduli and the microhardness of the glasses wereimproved with the increase of the MgO contents in the TM glasses, while Poisson’s ratio decreased withthe increase in MgO content. Moreover, the radiation shielding capacity was evaluated for the studied TMglasses. Thus, the linear attenuation coefficient (LAC), mass attenuation coefficient (MAC), transmissionfactor (TF) and half-value thickness (D0.5) were simulated for gamma photon energies between 0.344 and1.406 MeV. The simulated results showed that glass TM10 with 10 mol % MgO possess the highest LACand varied in the range between 0.259 and 0.711 cm 1, while TM45 glass with 45 mol % MgO possess thelowest LAC and vary in the range between 0.223 and 0.587 cm 1 at gamma photon energies between0.344 and 1.406 MeV. Furthermore, the BXCOM program was applied to calculate the effective atomicnumber (Zeff), equivalent atomic number (Zeq) and buildup factors (EBF and EABF) of the glasses. Theeffective removal cross-section for the fast neutrons (ERCSFN,PR) was also calculated theoretically. Thereceived data depicts that the lowestPR was achieved for TM10 glasses, wherePR ¼ 0.0193 cm2 g 1,while TM45 possesses the highest ERCSFN wherePR ¼ 0.0215 cm2 g 1.
