Abstract

We obtained the radionuclide concentrations of ²³⁸U, ²³²Th, and ⁴⁰K in various samples of the granite stones by measuring with a high efficiency NaI(Tl) (10.16 cm ´ 10.16 cm) scintillation detector. The activities of ²³⁸U, ²³²Th, and ⁴⁰K were recorded and determined by a full-spectrum analysis. The concentrations of radionuclides were found to be in ranges of 32.3-92.6 Bqkg^-1, 23.9-52.2 Bqkg^-1, and 796.5-2018.4 Bqkg^-1 for ²³⁸U, ²³²Th, and ⁴⁰K, respectively. The radiological dose rates and the hazard indices were also calculated in this analysis.

Key words: g-ray spectrometry, NaI(Tl), radioactivity, dose characteristic, granit, MCNPX
