Abstract: The necessity for advanced shields in facilities and environment where ionization radiation is encountered and utilized cannot be overemphasized. In the present research, the physical and radiation (photon and neutron) shielding potential of novel tellurite-based glasses with composition (90-x)TeO 2 -10TiO 2 -xWO 3 (where 0≤ x ≤ 30 mol. %, with an interval of 7.5) were evaluated and analysed. The glasses were coded TeTiW1, TeTiW2, TeTiW3, TeTiW4, and TeTiW5, respectively. The physical and photon and neutron shielding attributes of the glasses were then assessed using established procedures The glass density increased with increasing WO 3 with values ranging from 4.622 to 5.863 gcm−3. TeTiW5 showed superior MAC and LAC values between 68.0128 and 0.0408 cm2 g-1 and 398.7593-0.2393 cm−1, respectively compared to TeTiW1 (90TeO 2 :10TiO 2) with values between 39.9775 and 0.0373 cm2 g-1 and 184.7758-0.1724 cm−1for MAC and LAC, respectively at 0.015-15 MeV. Noticeable declined in mean free path and half value layer (HVL) was also obtained with increasing WO 3 across the glass series. Whereas, neutron removal (Σ R) improves across the series with values ranged 0.0897, 0.0929, 0.0984, 0.1038, and 0.1092 cm−1, for TeTiW1, TeTiW2, TeTiW3, TeTiW4, and TeTiW5, respectively. These results highlighted the promising potential of the prepared tellurite-based glass systems as shields for ionization radiation, supporting Sustainable Development Goal 3 (SDG 3).
