This manuscript has investigated the radiation absorption properties of some industrial materials. The most widely used for industrial purposes gamma radioisotope source is Co-60. In this study, the linear attenuation coefficients of some industrial steel samples have been measured at 1773, and 1332 keV photon energies using a gamma spectrometer that contains a 3”x3” NaI (Tl) detector and connected to Multi-Channel Analyzer (MCA). These results have been used to calculate the obtained radiation shielding parameters. As a result of this study, it was seen that industrial steels were more suitable among radiation shielding materials than the granite and concrete samples studied.
