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.
