%X 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 Ukmerg  city. Kalvi kiai 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.  Article in Lithuanian Nagrin jama radionuklid  137Cs, 40K ir 232Th perna a i  po vaismed iu esan io dirvo emio   tiriamojo vaismed io sandus. Tirti pasirinkti 3 vaismed iai i  dviej  skirting  augimvie i . Pirmoji augimviet  buvo Ukmerg s rajonas, Jogvil  k., kurioje tirtas dirvo emis ir obels sandai. Antroji augimviet  ¨C Visagino sen., Kalvi ki  k., kurioje nagrin ta radionuklid  perna a i  dirvo emio   kriau  s ir obels sandus. Aptariama dirvo emio ir vaismed io sand  paruo imo radiometriniam tyrimui metodika. Pateikta perna os faktori  vertinimo metodika. Analizuojami gauti perna os faktori  tyrimo rezultatai. I nagrin jus rezultatus gauti 137Cs, 40K ir 232Th perna os d sningumai, priklausomai nuo vaismed io r¨± ies ir nuo nagrin jamo sando. Gauta, kad kriau  s vaismedis visus tris nagrin tus radionuklidus kaupia labiau, lyginant su obelimis.  vertinus radionuklid  perna     atskirus vaismed i  sandus nustatyta, kad 137Cs, 40K ir 232Th ma iausiai kaupia vaismed i  vaisiai, labiausiai ¨C  iev , lapai,  aknys.
