Biomonitoring 137Cs in raised bog ecosystem by fruit bodies of Leccinum holopus — the Birch mushroom marsh

Abstract

For biomonitoring ¹³⁷Cs in the raised bog ecosystem the phenomenon of hymenophore layer morphological attribute changing of Leccinum holopus — the Birch mushroom marsh — in reply to accumulation of radionuclide in fruit bodies has been used. It is established that concentration of radionuclide in fruit bodies of Leccinum holopus, in all points of gathering located on a route, exceeds the limits of admissible values by 3,0–3,9 times. In fruit bodies of Suillus variegatus, Suillus flavidus, Lactarius helvus, Russula emetica, collected on a route, the excess of admissible values by 1,8–2,6 times is also established.
