KLÁN J., ŘANDA Z., BENADA J., HORYNA J. (1988): Investigation of non-radioactive Rb, Cs, and radiocaesium in higher fungi. Česká Mykologie 42(3): 158-169 (published: 12th August, 1988)
abstract
The concentration factors for non-radioactive Rb, Cs, and radiocaesium in the fruit bodies of mushrooms were determined. The difference between the concentration factors of non-radioactive and radioactive Cs from the last fallout was one order of magnitude. No significant differences were found between the concentration factors of stable Rb and Cs for mushrooms and vascular plants. The highest accumulation of radiocaesium was observed in Boletus spp., Laccaria spp., Paxillus involutus, Cortinarius armillatus, and Lactarius rufus. The contribution of older weapon-test fallout and the more recent 1986 Chernobyl fallout could be differentiated by isotopic ratio. The radiation dose from consumption of 10 kg fresh mushrooms did not exceed 20% of the dose from natural background radiation in Czechoslovakia.
