Özet

In this study, the gamma-ray energy-dependent mass and linear attenuation coefficients of various granite and Turkish marble species have been experimentally obtained. Radionuclides (Ba-133, Cs-137, Co-60 and Na-22) with point geometry were used as gamma-ray sources. The absorption capacity of each sample at nine.-ray energies was measured using a high resolution gamma-ray spectrometer equipped with a high purity germanium (HPGe) detector. To obtain the precision of the results (1s standard deviation of the single value), this procedure was repeated six times for each species of granite and marble, respectively. The energy-dependent mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), the half (HVL) and the tenth value layer (TVL) were calculated following that the MAC and LAC results were compared to the literature values.
