Transfer of radionuclides in natural and semi-natural environmentsFunded under: FP1-RADPROT 6C
The passage of the Chernobyl cloud over Western Europe has potentially contaminated a wide range of natural and semi-natural ecosystems. These include alpine meadows, upland pastures and moorland dominated by heather, the coniferous and deciduous forests of the Boreal and Atlantic types of vegetation and the tundras of the Nordic countries. These areas are very often used as pastures for grazing ruminants such as cows, goats and sheep as well as for hunting. Many of the contaminated areas are associated with soils of poor quality, often waterlogged, and of a high organic content. Agricultural activity is absent or minimal. Relatively little is known concerning the cycling of radionuclides and their bioavailability, their migration in undisturbed natural profiles, and the transfer (runoff, erosion, accumulation in litter) of contamination to adjacent areas under such conditions. Due to the heterogeneity of these systems, problems arise when transfer factors need to be determined. The usual radioecological definition therefore needs to be adapted correspondingly and the extrapolation of laboratory results and those obtained in the agricultural situation have to be investigated.
