The total photon interaction cross sections at six energies in the energy range 30–660 keV are determined in ten compounds, (NaNO3, KNO3, Sr(NO3)2, NaCl, SrCl2∙6H2O, BaCl2∙2H2O, NaClO3, (NH4)2SO4, MgSO4∙7H2O, and K2SO4) using a NaI(Tl) scintillation spectrometer in a good geometry setup. Analysis of the experimental data in terms of cross sections and effective atomic numbers is presented.
