INVESTIGATION OF TRANSFER FACTORS OF NATURAL RADIONUCLIDES FROM SOIL TO FODDER IN KARS, TURKEY

Abstract

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.
