[The contamination of food trout and carp from Bavarian fish farms with radiocesium (Cs-137 + 134) 1986 to 1989 as the result of the nuclear power plant accident at Chernobyl].

After the nuclear power station accident of Chernobyl at 26. 4. 86 Southern Bavaria was contaminated with radionuclides as J-131, Cs-137 and Cs-134. After three months only the Cesium nuclides had bearing on food, accordingly for fish. The accumulation of total Cesium (137 + 134) in the muscle of trout and carp had reached levels of 30 and 80 Bq/kg on an average and levels for 300 and about 800 Bq/kg were determined as maximum. The more naturally fed carps had have in the first two years a higher accumulation than the trout. Then the accumulation was equally on a low level near zero.
