Abstract In the present investigation we have measured here the mass attenuation coefficients (μm) of six oxides such as aluminum, manganese, copper, nickel magnesium for 122–1330 keV. Photons are measured using the radioactive sources Co57, Ba133, Cs137, Na22, Mn54 and Co60. To detect gamma rays NaI(Tl) scintillation detection system was used. The investigated attenuation coefficient values were then used to determine the other important parameters like linear attenuation coefficient (μ), total atomic cross sections (σt), molar extinction coefficients (ε), electronic cross sections (σe), effective atomic numbers (Zeff) and effective electron densities (Neff) of these oxide. Graphically it is observed that the variations of μm, σt, ε, σe, Zeff, and Neff with energy The values of μm, μ, σt, ε, σe are higher at lower energies and they decrease sharply as energy increases. The XCOM data is used to calculate Theoretical values. We were observed that the Theoretical and experimental values are found to be in a good agreement (error < 4%).
