Abstract：
:In this study the runoff of (137)Cs, mainly originated from the Chernobyl fallout, from highly contaminated alpine regions in Salzburg (Austria) is discussed. Twenty-five water-samples and 25 sediment-samples were taken from creeks of different size to determine the runoff of dissolved (137)Cs and Cs-binding characteristics to different particle size classes in the sediments. The hypothesis, that specific activity of the sediments depended on particle size and the surface of the particle, was proved with some modifications. Caesium activity concentration in water showed a negative correlation with electrical conductivity, while no significant correlations were detectable with other variables (pH, temperature, and altitude). Enormous differences and the variations found in the (137)Cs-concentrations in water can be explained by the electrical conductivity without any dependency on the inventory of the catchment. The sediment samples analysed showed a negative correlation between specific activity [Bq/kg] and particle-diameter, mainly explained by (137)Cs-uptake proportional to the particle surface per mass.
