This work explores the impact of the crystal’s unit cell and void volumes on radiation attenuation properties of spinel compounds. Spinel structures, including normal, inverse, and mixed spinels, were investigated for their diverse applications in fields such as γ-ray shielding, nuclear-based facilities including medicine applications. The MAC values of different spinel-based crystals were analyzed in the gamma-rays energy region, revealing that: MACZnFe2O4>MACCoFe2O4>MACFe3O4>MACMnFe2O4 >MACMn3O4 >MACMgFe2O4. The study showed that the MAC behavior was impacted by the spinel-group, unit cell structure, and atoms distribution within the spinel crystal. Additionally, the following relationship between (Spinel, MAC,Vtet, Vocta) was established as: (ZnFe2O4, 48.95, 0.36822, 0.28026), (CoFe2O4,33.24,0.37385, 0.27613), (Fe3O4, 43.25, 0.36264, 0.28442), (MnFe2O4,41.81, 0.34089, 0.29287), (Mn3O4,36.73, 0.34624, 0.27205), (MgFe2O4,40.13, 0.37955, 0.24841). The work has identified the best void volumes and compositions of divalent and trivalent ions for various spinel classifications, which improved radiation shielding effectiveness. These results offer important guidance for developing and refining spinel materials for radiation-related purposes.
