Glass with composition of 60TeO2−(30-x)ZnO–10PbO–xTiO2 (x = 0, 1, 2, 3, and 4 mol%) has been fabricated using melt quenching method at 900oC for 35 minutes. The glasses were characterized for gamma shielding properties using Phy-X PSD Lab software to obtain the Mass Attenuation Coefficient (MAC), Linear Attenuation Coefficient (LAC), Half Value Layer (HVL), Mean Free Path (MFP), and Tenth-Value Layer (TVL). Simulations were carried out within gamma photon energy ranging from 0.015 - 15 MeV. LAC and MAV values change dramatically within gamma photon energy range less than 1 MeV. At higher gamma photon energy range, the LAC and MAC tend to be constant. The HVL, which is the thickness of a material that can reduce the gamma ray intensity passing through it by one, increases as more TiO2 molecules are introduced into the glass to substitute ZnO.
