摘要: Abstract Empirical data on the 137 Cs activity concentration in meat of roe deer (C apreolus capreolus ) roaming 3 spruce forest areas and one peat bog area are presented compared. They cover time series nearly 20 years after a spike contamination 1986 originating from Chernobyl. A model is which considers three soil compartments to describe change availability with time. The time-dependency combination two components: (1) an exponential decay (2) peak second half each year during mushroom season. over can be described by sum functions. additional transfer into season depends precipitation. On higher more persistent than forest.
