Abstract

 In this research, concrete with different percentages of 0, 10, 25, 50, 75 and 100 of barite powder and 10% of graphite powder were investigated for the study of gamma protective properties. The transmitted fluxes of gamma-rays that were emitted from Cs-137 source were detected by a NaI(Tl) detector and analyzed by an MCA analyzer. Then, the samples were tested for compressive strength, tensile strength, ultrasonic pulse wave velocity and the linear attenuation coefficients. By comparing the obtained samples, it was observed that a sample containing 10% barite powder plus 10% graphite powder could be used as a protective material against gamma rays.
