Abstract: Study mass attenuation coefficient of new chemical compound C28H24N6O6Cu by using gamma ray radiation (γ), emitted from deferent sources Co57, Ba133, Na22 , Cs137, Mn54 and Co60 with energies from 122-1330 keV. The compound was subjected to gamma radiation and detector density of radiation that across the sample, used scintillation NaI(Tl) detector with resolution 8.2% (at 662 keV) to detector beam of gamma ray. The attenuation coefficient data has used to obtain the effective atomic numbers (Zeff) and effective electron densities (Neff), atomic cross-section (бt) and electronic cross-section (бe) of dinitratobis. It was observed that the effective atomic number (Zeff) and effective electron densities (Neff) initially decrease and tend to be almost constant as a function of gamma-ray energy. Zeff and Neff experimental values showed good agreement with the theoretical value which took from XCOM program of Hubbell J.H.for the individual elements.
