Abstract: Comparing the radionuclide inventories of sediment (90Sr,137Cs,230,240Pu,2,0Pbex,7Be) with the inventories expected from atmospheric fallout records, we find that the ratios are between 0.38-1.3 in the sediment core GR-83-11 of Lake Greifen. On the basis of the erosion in drainage basin and of the retention in laker a model is made from measured quantities to predict the radionuclide inventory ratio in this paper. The best agreements between calculated and observed inventories were obtained for the nuclides. For the calculated error. we would easily be explained by different mechanism of additional removal for individual nuclide.
