Abstract

The effect of magnetite ore rate on the gamma radiation shielding properties of concrete samples have been measured by using the transmission method for 59.54 and 80.99 keV gamma rays with a NaI(Tl) detector. Linear attenuation coefficients of concrete samples including magnetite in different rates were obtained by Lambert law in which measured gamma ray intensities were used. They were compared with theoretical values calculated from WinXCom computer software. It was determined that linear attenuation coefficients increased with increasing magnetite rate in concrete samples.
