In this study, three lead-free alloys, CrSbSe3, HfSnS3, and ZrSnS3 were selected to investigate their photon shielding properties using Geant4 MC toolkit. The simulated mass attenuation coefficient (MAC) are then benchmarked with theoretical data obtained from Phy-X software demonstrating excellent agreement between the data set with percentage difference below 2% confirming the consistancy between Geant4 MC toolkit and theoretical data. From the simulated MAC, different key shielding parameters such as linear attenuation coefficient (LAC), half-value layer (HVL), mean-free path (MFP), transmission factor, and radiation protection efficiency (RPE) were derived and analyzed in the incident photon energy ranging from 15 keV up to 15 MeV. The findings indicates that all investigated lead-free alloys exhibited superior performance and are highly promising alternative to lead-based shielding materials, particularly in medical and industrial applications.
