In this study the total atomic cross-section (σa), total electronic cross-section (σe), effective atomic number (Zeff) and effective electron density (Neff) of locally developed ilmenite-magnetite (I-M) concrete were calculated analytically for different photon energies from 1 keV to 20 MeV and compared with concretes of different densities and compositions. The effect of Zeff on the mass attenuation coefficient (μ/ρ, σa, σe) is shown graphically. The values of σa, σe, Zeff and Neff of I-M concrete were found to be higher than those of the ordinary concretes and in some cases than those of heavy concretes, which proved I-M concrete’s shielding effectiveness. The results of this study will provide some useful information for a shielding material database for practical shielding calculation.
Key words: atomic cross-section / electronic cross-section / effective atomic number / effective electron density
