Özet:

In this research work, the activity concentrations of 40K, 232Th and 226Ra in fodder plant samples such as wheat, barley, oats, corn slices, sainfoin and vetch grown in Kars region used for animal feeding have been determined. For this purpose, fodder samples were taken from different agricultural fields in Kars region, where the cows, sheep and poultry breeding were made. All samples were analyzed by means of gamma-ray spectrometer using NaI(Tl) detector. The average activity concentrations of 40K, 232Th and 226Ra were found to be 484.25±23.2, 35.25±7.2 and 28.95±7.0 Bqkg-1, respectively, in soil samples. In the fodder samples examined according to soil samples, the average activity concentration of 40K, 232Th and 226Ra were found to be 463.94, 59.45 and 16.20 Bqkg-1, respectively. The mean soil to plant transfer factors of these natural radionuclides for fodder samples were determined 0.95, 1.77 and 0.55, respectively.
