Determination of some trace elements in the food chain soil--plant--milk by activation analysis for evaluation of radionuclide transfer

In the study, concentration factors of elements were determined for the transfer in the food chain plant: milk for different ecological conditions, namely for the sandy soils, called geest, and the moor-land. The concentration factors of elements evaluated for both the types of grazing conditions differ only little. Since the concentration of the elements Ca, Fe, Co, and Zn in milk seem to be regulated by a homeostatic control by the animal organism for the given conditions, the differences of the concentration factors of these elements are primarily caused by the different concentrations in plants. Contrarily, the elements Rb and Cs seem to be regulated so weakly that their concentration factors agree well under the different grazing conditions in spite of large differences of the element concentration in plants
