Bryophytes and lichens as fallout originated radionuclide indicators in the Svalbard archipelago (High Arctic)
Arctic environment is very sensitive to anthropogenic pollutants, especially in terms of radionuclide contamination which persists in polar regions due to very slow biological turnover rate. The main aim of the study was to determine concentrations of 137Cs in selected cryptogamic species (bryophyte...
