In this study, shielding properties of granites which are produced in Turkey were studied for gamma ray and neutrons. Linear and mass attenuation coefficients for gamma ray were measured at 1.17 MeV, 1.33 MeV and 0.662 MeV by gamma spectrometry system containing NaI(Tl) detector. Pu-Be source was used in measuring linear neutron attenuation coefficients of the granite samples. Measurements were carried out by using narrow beam geometry by using gamma and neutron transmission technique. The gamma transmission results have been compared with winXCOM calculations and a good correspondence has been obtained.
