After the first peak of the radioactive cesium in the milk at the middle of May 1986 there has been occurred à second one during the winterseason. To describe these two peaks in the milk we have taken into consideration that the radioactivity of the fresh animal feed decreases exponentially and of the dry one is constant, exept the first year when it increases due to the storage of the most contaminated dry feed, The consumption rate of the freshes is derived as a proportional amount of the agricultural productivity that has been given by a Fourier series. The total consumption rate has been kept constant during the whole year. By use of the model it can be calculated the concentrations in milk for several years even by taking into consideration the root uptake of the pasture forage. The uncertatinty analysis has given confidence ranges of about one magnitude of the cesium content in the milk.
