Natural radioactivity is widespread in the earth and is present in different environment geological formations in the soil and rocks. Natural radionuclides in soil originate from the members of 238U and 232Th series, and 40K radionuclide is the main external source of radiation to the human body. In this study, concentrations of the natural radioactivity 226Ra, 232Th, and 40K are measured in soil samples collected along the Ganos fault. The radioactivity levels of the soil samples for the study are determined by scintillation gamma spectroscopy. Concentrations of 226Ra in the soil samples ranged from ND to 24.1 Bq kg−1, 232Th concentrations from ND to 40.2 Bq kg−1, and 40K concentrations from 315.9 to 748.9 Bq kg−1. Obtained results were compared with the literature data.
