Abstract

Annual needles of larch and cedar were sampled in the tundra zone of the Arctic part of Western Siberia in order to determine Be, Pb and Cs specific activities. Higher concentrations of Cs in the needles of cedar relative to the needles of larch can be associated with a clear difference in the properties of accumulation and translocation of caesium among these species. Higher concentrations of Be and Pb in the needles of larch relative to cedar needles and close isotopic ratios (Be/Pb) are probably due to more efficient aerosol deposition on vegetative canopies of larch.
