In this study, the activity concentrations of 121 soil samples gathered from diverse places of Sarıkamış of Kars were found out employing NaI (Tl) gamma spectrometry. It was monitored that the concentration of the natural radionuclides 40K, 226Ra and 232Th in the soil samples altered from 148.0±31.2 to 909.2±38.4 Bqkg-1, BDL to 38.1±8.9 Bqkg-1 and 7.6±0.7 to 53.0±7.4 Bqkg-1, respectively. Also relatively low deposits of 137Cs were found in the investigated area, where the activity concentrations ranged from BDL to 21.0±1.1 Bqkg-1. The determined average values of activity concentrations of 226Ra, 232Th and 40K were employed to work out the radiation hazard indices in soil samples. The total observed dose rate in the working area varied from 18.4 to 87.7 nGyh-1 with the mean value of 46.9 nGyh-1 and also the annual effective dose ranged between 22.6 and 107.5 µSv with the average value of 57.7 µSv. It was observed that the values established whenever compared to the world values allowed are under the standard limits for the environment.
