Abstract: With the extensive applications of radioactive materials, it is necessary to look for locally available and cheep materials to be efficient absorbers appropriate for shielding from radiation hazards. The attenuation and scattering coefficients of gamma-rays of different energies in thirty samples from two igneous rocks: diorite and andesite, the effects of sample density, ρ, with radiation energy (E) ranging from 0.36 to 1.33 MeV, were investigated by using a scintillation detector NaI (Tl). The chemical composition of major elements is measured by X-ray fluorescence (XRF). The results showed an inverse proportionality between the linear attenuation coefficient μ and E, and μ has a direct proportionality with the sample density, ρ. The side scattering coefficient φ, is directly proportional to E, but at the same time φ has an inverse proportionality with the sample density. The results showed an inverse proportional between the half value layers and the sample density ρ.
