Radionuclide soil-to-plant transfer - experiences from the Chernobyl accident in Austria

摘要

In field studies after the Chernobyl fallout in Austria distinct differences in soil-to-plant transfer of (sup 137)Cs and (sup 90)Sr between crops were observed. However, within single plant species transfer values varied over one to three orders of magnitude. The main influencing factors are the soil properties, the soil adhesion phenomenon and probably the unhomogeneous vertical distribution of the radionuclides after plowing. On the basis of the presented results we should be aware of the uncertainties of the simple soil-to-plant transfer model, which partly mask the influence of soil parameters on root uptake and translocation.
