Cel The major objectives of this project, which will be carried out in natural and semi-natural environments within the 30 km zone around Chernobyl, are i) the determination of the long-term behaviour of caesium, strontium and actinides in meadow and forest environments with particular emphasis on the physical, chemical and biological factors that affect transfer through the wildlife-plant-soil systems, and ii) the determination of the role of these environments in the transfer of the radionuclides to the neighbouring systems. Radionuclide behaviour in forest ecosystems. Studies carried out after the Chernobyl accident have shown the interception of airborne radionuclides by tree canopies is an initial and important processes in the transfer of radionuclides to these environments. The following investigations of the behaviour of caesium, strontium and actinides should be made in coniferous and deciduous forests: their vertical migration in soil as a function of their physico-chemical forms; their availability for transfer between soil layers on the basis of their physico-chemical forms in soil solution; the role of soil and soil solution characteristics on their uptake by different vegetation species (tree, herbaceous plants, shrubs, mushrooms, etc); the role of the litter decomposition on their migration in soil; the role of micromycetes on radionuclide migration; intake by and transfer within wild animals; the role of soil intake in their transfer to animals and the significance of hot particles. Radionuclides behaviour in meadow ecosystems The profile of radionuclides, deposited during the Chernobyl accident, in soil appears to be strongly influenced by the soil type and its water content. In the well drained soils in the Chernobyl area the radionuclides are mainly retained in the soil layers; in wet areas higher mobility has been observed in peat soil. The following investigations should be made of the behaviour of caesium, strontium and actinides in semi-natural meadows and bogs: vertical and lateral migration in soil as a function of their physico-chemical forms; availability for transfer between soil layers as a function of their physico-chemical forms in soil solution; role of micromycetes on their migration between soil horizons; role of soil and soil solution characteristics on their uptake by different species of vegetation; role of fertilisers on their uptake by different species of vegetation.
