Abstract: The soil-plant transfer of Cs-137 and Sr-90 in different crops was determined with respect to the presentdayamendment practice of using digestate from biogas fermenters. The studies were performed usinglarge lysimeters filled with undisturbed luvisol monoliths. In contrast to the conservative tracer, Br,neither of the studied radionuclides showed a significant vertical translocation nor effect of the applieddigestate amendment compared to a non-amended control was found. Furthermore, no significant plantuptake was measured for both nuclides in wheat or oat as indicated by the low transfer factors betweensoil-shoot for Cs-137 (TF 0.001e0.010) and for Sr-90 (0.10e0.51). The transfer into nutritionally relevantplant parts was even lower with transfer factors for soil-grain for Cs-137 (TF 0.000e0.001) and for Sr-90(0.01e0.06). Hence, the amendment with biogas digestate is unfortunately not an option to furtherreduce plant uptake of these radionuclides in agricultural crops, but it does not increase plant uptakeeither.
