The photon attenuation parameters were calculated and analyzed using Phy-X/PSD and NGCal software over the range of 0.015–15 MeV. The results, based on the total interaction cross-section of photon–matter interactions, show that all investigated samples exhibit higher attenuation efficiency in the low-energy region due to the dominance of the photoelectric effect, followed by a gradual reduction in shielding performance in the intermediate and high-energy regions, where Compton scattering and pair production prevail. Materials with higher atomic number (Z) and greater density demonstrate superior shielding performance, as reflected by higher MAC and LAC values and lower HVL, TVL, and MFP values. The radiation shielding parameters obtained from the two software tools were in good agreement, with differences within 0.1%. Overall, both perovskite families display promising radiation shielding capabilities, with oxide double perovskite samples showing enhanced attenuation efficiency compared to metal oxide–based perovskite composites, highlighting their greater potential for effective photon radiation shielding applications.
