The effective atomic number (Z(eff)) of SixPb0.7-x(Fe2O3)(0.3) ternary alloys was obtained for photons. Rayleigh to Compton scattering ratio (R/C) has been determined to obtain the Z(eff) of SixPb0.7-x(Fe2O3)(0.3) ternary alloys of varying Si and Pb (10 %-60 %) content for scattering of 59.54 keV gamma-rays at an angle of 130 degrees. The theoreticalR/C ratios of elements were plotted as a function of the atomic number and fitted to a polynomial equation. ExperimentalR/C values of alloys were then used to obtain Z(eff) using this fit equation. Also, Z(eff) values of these alloys were determined for the first time by interpolating theR/C of the material using the RIC data of adjacent elements in between the RIC of the alloy lies. The agreement between the interpolation method and the fit equation was quite satisfactory. The obtained Z(eff) for photon scattering were then compared to the Z(eff) for total photon attenuation obtained using the Auto-Zeff program. Significant variations were observed between the Z(eff) for scattering and the total attenuation of gamma rays.
