Abstrakt: To determine their transfer factors, activity concentrations of natural radionuclides were measured in the leaves and acorns of holm oak (Quercus ilex L.) trees collected from seven locations with different soil properties and radionuclide activity concentrations. The chemical and mineralogical compositions of the soils were also analysed to investigate the effect these had on radionuclide absorption by the trees. Soil chemistry showed significant effects on radionuclide incorporation into Quercus ilex L. tissues. A significant relationship was established between activity concentrations and soil content of Ca and P with 238 U and 226 Ra in the leaves and acorns of Quercus ilex L. Differentiated transfer was found for 40 K, which showed greater transfer to the leaves than the other radionuclides. The activity concentration of U and 226 Ra was higher in the fruits than in the leaves, with the opposite effect being observed for 40 K. The risk of U and 226 Ra transfer into the food chain through acorn consumption by livestock is predicted to increase in soils poor in Ca and rich in P.
