Annual needles of larch and cedar were sampled in the tundra zone of the Arctic part of Western Siberia in order to determine 7Be, 210Pb and 137Cs specific activities. Higher concentrations of 137Cs in the needles of cedar relative to the needles of larch can be associated with a clear difference in...
