Abstract: We present seasonal results of ¹²⁹I in fresh-water lakes located in central Sweden, an area over which the amount of fallout deposition from the Chernobyl accident varied significantly (2–120 kBq/m² for ¹³⁷Cs). ¹²⁹I concentrations in the lakes ranged from 2.1 to 15.0×10⁸ atoms per liter and did not show elevated concentration in lakes located in regions of high Chernobyl fallout. Apparently, the studied region is strongly influenced by ¹²⁹I releases from the reprocessing facilities through precipitation. Desorption or resuspension of ¹²⁹I from soils and sediments does not seem to be an active process to increase the concentration of ¹²⁹I in the lakes.
