The present study investigates the gamma-ray attenuation and shielding characteristics of six selected transition-metal salts, designated as CM, SiC, DPt, TClP, LTCl, and PClNb, using experimental measurements and theoretical calculations over the photon-energy range of 122–1330 keV. The experimental mass attenuation coefficients (MACs) were determined from gamma-ray transmission measurements and compared with theoretical values calculated using the NIST XCOM database. The linear attenuation coefficient (LAC), mean free path (MFP), half-value layer (HVL), and tenth-value layer (TVL) were evaluated to provide a comparative assessment of the shielding performance of the investigated materials. The results demonstrate that the MAC and LAC generally decrease with increasing photon energy, whereas the MFP, HVL, and TVL increase, indicating that greater material thickness is required to attenuate higher-energy gamma photons. Among the investigated samples, S3 exhibits the highest MAC and LAC values and the lowest MFP, HVL, and TVL values over the studied energy range, suggesting superior gamma-ray attenuation performance relative to the other samples. The theoretical and experimental MAC values show generally good agreement, although a deviation observed for S5 at 1170 keV requires further verification. The findings highlight the influence of material composition and density on photon attenuation and identify S3 as a promising candidate for further radiation-shielding investigations. Additional experimental validation and assessment of mechanical properties, cost, and practical application requirements are necessary before recommending these materials for specific radiation-protection applications.
