Use of the fallout radionuclide cesium-137 (137 Cs) as a tracer has been widely employed for assessment of soil losses and dating of deposited sediment. Mean annual sedimentation rates over the last 20-30 years were determined in the pre-alpine Mondsee (Upper Austria) using Cs-137 and Pb(Po)-210 profiles for.
