Matveeva I. Modeling of radioecological processes by a method of box models at an estimation of ecological situation for local ecosystems

In dissertation the results of the analysis of flows of radionuclides Cesium 137 on an example of village Galusiya of Volunsk area and village, contaminated by Strontium-90 (village Kozubinchiki of Ternopil area). The analysis is carried out by a method of box models. The block schemes of ecosystems were created, and the mathematical models by a method of box models are developed. It has allowed to estimate ways of formation of doze loadings from inner irradiation at the expense of the use of products of meal for different cohort of the population working, pensioners and children, and thus to prognoses dynamics of these doze loadings the next years after Chernobyl accident. Is established, that of doze loading in these villages are formed on any other ways depending on a kind of radionuclide, structure of pastures and levels of their pollution. As a result of researches we create the simplified system type of radioecological research local ecosystems of the occupied items, which include the basicparts of trophic chain: ground, hay, cow, milk, forest's products, and people.
