Abstract
Shortly after the Chernobyl accident, resuspension factors for 137Cs were determined in Hannover, Germany. In the first few weeks after deposition a clear dependence of airborne 137Cs concentration, which ranged between 0.5 and 10 m BQ m-3, on wind speed was observed. Best fit to the data was obtained for a power exponent close to unity. After a few months, even during strong wind periods with appreciable dust resuspension, radioactivity concentrations were below the detection limit.
