Fast quenching was used to create glasses in the xFe2O3·(40x)Ag2O·60P2O5 system (0 ≤ x ≤ 20 mol%). Fourier transform infrared spectrum (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) were used to investigate the structure of the glasses. A gradual increase in Fe2O3 content leads to an increase in P–O–Fe bonds, which increases the durability of the glass structure. The Hardness number (Hv) of the investigated glasses increases with increasing Fe2O3 content. The measured density decreases, and the calculated molar volume increases with increasing iron oxide concentrations. The mass attenuation coefficient was calculated using the WinXCOM program after being measured experimentally. The experimental and theoretical values are in good agreement. The gamma-ray shielding parameter HVL was calculated to understand the radiation shielding performances of the investigated glasses. The results show that as the Fe2O3 content increases, the mass attenuation coefficient (μm) decreases. The glass with the lowest HVL values contains 5 mol% Fe2O3.
