Simulation model of 137Cs dynamics content in food chain components of terrestrial ecosystem

Abstract

Some aspects of application of simulation modeling of radionuclide behavior in food chains of terrestrial ecosystems are discussed. The model of behavior of ¹³⁷Cs in the system of type soil-vegetation-herbivores-predators is described. The results of modeling, including the calculation of the dynamics of dose load on animals, are presented. It is shown that in the simplified “Chernobyl” scenario of the radiological situation, dose loads on herbivores are significantly lower than on predators. In general, in animals in the first 10 years, the main contribution to the dose load is made by external irradiation. Then the external and internal dose loads become approximately equal.
