The study reveals the factors of transferring radionuclides 137Cs, 40K and 232Th from soil under fruit trees to the components of fruit trees. Three fruit trees growing in two different places were chosen. 6 soil samples and apple tree components were taken from Ukmergė city. Kalviškiai near Visaginas town is the second place of growing apple and pear trees to the components of which the transfer of radionuclides was made. The article discusses the methodology of preparing fruit tree components for radiometric research and submits the evaluation methods for transfer factors. The paper analyzes the obtained results of research on transfer factors. The conducted analysis has showed that 137Cs, 40K and 232Th patterns of transfer depend on the type of a fruit tree and on the investigated components. The study has also disclosed that the pear tree collects all examined radionuclides to a greater extent than apple trees. Finally, the evaluation of transferring radionuclides to separate fruit tree components displays that the least amount of 137Cs, 40K and 232Th is found in the fruits of the trees, whereas the biggest - in bark, leaves and roots.
