Level and origin of Iodine-129 in the Baltic Sea.
Original language description
Environmental samples, such as seawater, seaweed, lake water, lake sediment and grass collected from the Baltic Sea area were analyzed for I-129 and I-127 by radiochemical neutron activation analysis. In 2000, the concentration of I-129 in the seawater from Borholm and Moen in the Baltic Sea has reached 6.0x10(-13) and 16x10(-13) g/l, respectively, these are more than two orders of magnitude higher than the global fallout level. The highest value of 270x10(-13) g/l being found in the seawater from the Kattegat. By comparison of the level of I-129 in the lake water and precipitation in this region, it is estimated that more than 95% of I-129 in the Baltic Sea originates from reprocessing emissions, especially from the French nuclear fuel reprocessing plant at La Hague. More than 30% of I-129 in the south Baltic and 93 % in the Kattegat directly originates from the marine discharges of the European reprocessing plants.
