摘要：

We present seasonal results of I-129 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/m(2) for Cs-137). I-129 concentrations in the lakes ranged from 2.1 to 15.0 x 10(8) 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 I-129 releases from the reprocessing facilities through precipitation. Desorption or resuspension of I-129 from soils and sediments does not seem to be an active process to increase the concentration of I-129 in the lakes. (C) 2001 Elsevier Science Ltd.
