On the Stabatishke site near to Ignalina Nuclear Power Plant a near surface repository for low and intermediate-level short-lived
radioactive waste is being constructed to store the waste which was produced during the decommissioning of the Ignalina Nuclear
Power Plant. A possible spread of radionuclides from the near surface repository and the radiation level of expression are
one at the most important aspects while evaluating the safety of the repository. The article examines the specific activity
of artificial (137Cs, 90Sr) and natural (226Ra, 232Th, 40K) radionuclides in the soil of Stabatishke site of Ignalina NPP in pinewood; the spread of these radionuclides is determined
in the system “soil-tree”. The change of long term soil pollution with artificial radionuclides was estimated. This is a background
soil pollution which had been there before the exploitation of the near surface waste repository. The transfer factors of
natural (226Ra, 232Th, 40K) and artificial (137Cs, 90Sr) radionuclides from the 0-to-20-cm soil layer to different annual pinewood rings were measured. After estimation of the
position of pine roots in accordance to the soil vertical and the annual change of the plant biomass, the transfer factor
of 137Cs movement to different annual pinewood rings from the separate 0 to 20-cm soil layers was determined.
A preliminary result employing neutron activation tomography in the study of the diffusion of a preservative in a sample of Scots pine is presented. The ability to determine the spatial distribution of elements within the wood without recourse to destructive sectioning makes this a better technique than others currently available.
