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