摘要: Abstract Wild growing mushrooms are traditional food items for man and also an important source of nutrients small big wildlife. Nevertheless, they can be species - specifically vulnerable contamination with heavy metals radionuclides. We studied a less known phenomenon accumulation highly toxic, the alpha-radiation emitter such as 210Po beta 210Pb by three Leccinum mushrooms: orange oak bolete L. aurantiacum (Bull.) Gray (previous name aurantiacum var. quercinum Pilat), foxy L. vulpinum Watling slate L. duriusculum (Schulzer ex Kalchbr.) Singer. Fungal soil materials were collected from areas different geochemical composition in northern regions Poland. In parallel evaluated was risk to human consumer due possible intake mushroom meal. Results showed heterogeneous distribution activity concentrations within caps stipes fruiting bodies. Overall concentration whole dried fungi material ranged 0.59 ± 0.38 3.2 ± 0.2 Bq kg−1 0.45 ± 0.04 3.1 ± 0.2 210Pb kg−1. Evaluation that consumed locals typical quantity 0.5 kg (dry biomass) contribute into annual effective radiation dose at 0.90–3.81 μSv decay 0.31–2.14 μSv 210Pb decay, which is portion inhabiting
