| Abstract: | The concentration of naturally occurring40K and137Cs from fallout were determined in various mushrooms as well as in a few samples of forest soil from the same region over
the period of 1984–1988. The137Cs content in mushrooms before the reactor accident at Chernobyl was generally below 500 Bq kg−1 dry matter, except Paxillus involutus /2700 Bq kg−1/. A remarkable increase of the137Cs activity /up to ten times/ was observed in 1986. For almost all examined species this activity remained basically at the
same level for the next two years. No correlation between40K and137Cs in mushrooms has been found. |
