This study aims to investigate the ability of as-prepared PbSn 3 Sbx( x  = 0.0, 0.5, 1.5, and 2.5 wt.%) alloys for shielding against gamma-rays, the relationships between the mechanical properties and gamma-ray shielding parameters for four types of alloys have been studied and analyzed. Gamma-ray interaction with the as-prepared alloys has been discussed mainly in terms of total mass attenuation coefficient ( µ m), linear attenuation coefficient ( µ ), half value layer (HVL), and mean free path ( X m). From X-ray analysis, a crystalline intermetallic compound phase of SnSb is detected. The formation of the intermetallic compound phase and refinement of evaluated particle size causes a pronounced enhancement in internal friction, dynamic elastic modulus, and microhardness indentation. Attenuation shielding parameters of as-prepared alloys with free antimony are measured and calculated. It is noticed that the obtained results showed desirable values of shielding parameters. Mechanical properties and Vickers microhardness, H v  are critically evaluated and sensitive to changes in temperature and Sb antimony additions. Thus, the study indicates that 2.5 wt.% Sb alloy sample has a distinguished protection ability to attenuate the gamma-ray radiation. It can be concluded that the Sb additive for this type of binary alloys at content 2.5 wt.% can help to increase the shielding gamma-ray performance.
