In this paper, measurements were carried out of the calculated attenuation of the ranges gamma rays energy(279,356,479,662) KeV and using radioactive sources (Hg^203, Ba^133, W^189, Cs^137). In the current results has determined (μ_L, μ_m) by using Monte Carlo simulation (i.e. through the account of each of the intensity falling and intensity transmit in samples proposed in search ) .permission has been drawing relationship graphs between the logarithm of the absorbance and thickness proposed for each of the ionic crystals (CsI, CdTe), hence slope graphs relationship represents attenuation coefficient linear and thereafter are calculated attenuation coefficient mass through during the relationship the following (μ_m = μ_L / ρ), and the results showed the current search using the Monte Carlo that the values of coefficients mass attenuation of gamma rays in crystals (CsI, CdTe) converge and overlap with each other at high energies the fact that the attenuation depends vitally on Compton scattering , either the values of attenuation coefficients linear showed a variation the obvious fact that the attenuation coefficient depends on the density of the absorbed . Addition, the study was examine to calculate the total atomic cross section and electron density, and the results of this study showed good agreement with the XCOM package.
