| Özet |
| A gamma spectrometric study of distribution of natural and artificial radionuclides in soil samples collected from the terrestrial environment of Gerze counties of Sinop Province in Turkey was performed using a NaI (Tl) γ-ray spectrometer with the aim of estimating the radiation hazard as well as establishing a database for radioactivity levels of the tourist area. The concentrations of primordial (238U, 232Th and 40K) and the fission product (137Cs) radionuclides were determined. The mean activity concentrations of 238U, 232Th, 40K and 137Cs were determined as 63.87±1.09, 72.66±1.70, 609.65±5.92 and 13.58±0.48 Bqkg-1 for soil samples, respectively. Based on the measured concentrations of these radionuclides, the mean absorbed gamma dose in air and the annual effective dose due to terrestrial gamma radiation were calculated. The contribution to the total absorbed gamma dose rate in air in the decreasing order was due to the presence of 232Th (44%), followed by 238U (30%), 40K (25.6%) and 137Cs (0.4%) in Gerze soils. In situ measurements of the gamma dose rate in air were performed in the same 60 locations, soil samples were collected from, using a portable GM tube and the mean gamma dose rate and the annual effective dose were ascertained. |
