| Popis: | Determinations made after the Chernobyl accident on rain water collected under spruce and oak trees show that there is a good correlation between the deposition fluxes of both radiocaesium and stable potassium, at least under spruces, suggesting that potassium could be used as an indicator of the behaviour of Cs-137 in contaminated trees. Four years after the accident, it seems that a short-term (1-3 y) equilibration has been reached in the contaminated trees and that radiocaesium is now transferred by trees to the soil mainly via throughfall. |
