Abstract: Radiologically-contaminated forest and natural ecosystems contribute significantly to the human radiation dose in the intermediate (several years) and long (several decades) terms following the radionuclide release. As a result of the Chernobyl nuclear power plant accident in 1986, extensive forested areas in Europe were significantly contaminated with cesium, strontium, plutonium and other radionuclides. This study develops a dynamic model that describes the pathways of radionuclides which undergo complex transfer processes in forests and natural ecosystems. This generic model, FORESTRATH, calculates time-dependent radionuclide concentrations in forest compartments based on the information available on residence half-times. Because of the high complexity, traditional sampling programs often provide only limited and fragmented information for the ecosystem to be modeled. A model-directed sampling program was initiated which implies close feedback between ecosystem sampling and modeling of the radionuclide pathways using the FORESTPATH model. This program is now being applied by an international team of USA, European Union (EU) and Newly Independent States (NIS) members in the Chernobyl Nuclear Power Plant (NPP) Exclusion Zone.

Abstract: Chernobyl accident has influenced greatly all spheres of life of the affected territories, changing the life-style of the local population. [1, 2]. Investigation of the radionuclides behavior in natural conditions becomes more and more important which is connected with the fact that radionuclides are drawn into substances rotation and are actively accumulated by the plants and animals, that means that they become integral link of the food chains and are of a great importance in the functioning of the ecosystems. Deposition of radionuclides in the forest system is often higher than in agricultural arrears. Specific ecological features of the forests often lead to the high degree of accumulation of contaminating radionuclides. Organic matter high content in the forest soil and its stability increase the transfer of radionuclides from soil into plans which lead to high content of radionuclides in lichens, mosses, mushrooms and berries. Radionuclides transfer to game in such conditions could bring to the situation when some people actively consuming game meet will be highly exposured

Abstract: In an attempt to understand the mechanisms governing the transfer and retention of radiocaesium in the understorey vegetation, 39 macromycetes species and 33 plant species, together with humus samples, were systematically collected from the undercover vegetation in a boreal coniferous forest. The results indicate that the main factors determining interspecific differences in contamination level are the rooting depth in plants, the depth of mycelium in fungi, and the ecophysiological behaviour of fungi, mycotrophism or plant parasitism.
