ABSTRAKT

Levels of 137Cs and 90Sr accumulation in wild-growing lygnotrophic macromycetes Trametes versicolor (L.:Fr.) Pilat, Fomes fomentarius (L.:Fr.) Gill. Heterobasidion annosus (Fr.) Bref., Hypholoma fasciculare (Huds.:Fr.) P. Kumm., Piptoporus betulinus (Bull.:Fr.) P. Karst., Pleurotus ostreatus (Jacq.:Fr.) P. Kumm., which grew in the Exclusion Zone (an area ranging 20 km to the south of Chernobyl NPP) and in cultivated Pleurotus ostreatus and Lentinus edodes (Berk.)Singer grown on wood substrates taken from the territory of "Red forest-2" (ranging 4 km to the north of ChNPP) was measured using gamma spectrometry and radiochemical analysis based on the accumulation of 90Y.The ratio of 137Cs/90Sr in mushrooms that grew in natural conditions ranged from 0.5 to 37 (averaging 13.7), and the ratio was generally three times higher than in experiments with cultivation conditions (from 0.085 to 0.169, averaging 0.120). It appears that higher levels of contamination with radiostrontium in cultivated lignotrophs were associated with its higher biological availability in homogeneous and watered substrates. The maximum level (32251 Bq/kg dry weight) of 90Sr was observed for P. ostreatus on pine substrate. Some increase in radiostrontium content in woods observed during the last years in territories contaminated with radioactive Sr will inevitably cause an increased content in lygnotrophic macromycetes. In order to promote ecological safety, the selective monitoring of 90Sr content in fruiting bodies of cultivated lignotroph species even in territories with a low surface contamination is strongly recommended.
