| Popis: | Environmental samples, such as seawater, seaweed, lake water, lake sediment and grass collected from the Baltic Sea area were analyzed for 129 I and 127 I by radiochemical neutron activation analysis. In 2000, the concentration of 129 I in the seawater from Borholm and Moen in the Baltic Sea has reached 6.0×10 −13 and 16×10 −13 g/l, respectively, these are more than two orders of magnitude higher than the global fallout level. The highest value of 270×10 −13 g/l being found in the seawater from the Kattegat. By comparison of the level of 129 I in the lake water and precipitation in this region, it is estimated that more than 95% of 129 I in the Baltic Sea originates from reprocessing emissions, especially from the French nuclear fuel reprocessing plant at La Hague. More than 30% of 129 I in the south Baltic and 93% in the Kattegat directly originates from the marine discharges of the European reprocessing plants. |
