Shielding of gamma radiation primarily involves the interaction of gamma radiation with matter. In this measurements have been made to determine the absorption parameters of Carbon, Copper and lead elemental materials of gamma-rays photons from 22Na, 137Cs and 60Co sources using the NaI (Tl) detector. The attenuation in the intensity of the beam will be determined for each varying thickness of absorber materials. Absorption properties were interpreted by means of the linear attenuation coefficient µ, mass attenuation coefficient µm ,half-value layer thickness and ten value layer thickness. Among these the mass absorption coefficients is the most specific parameter because it can be specified only by gamma ray energy.
