Model for food chain transfer and dose assessment in areas of the Slovak Republic

The radio-ecological model ECOSYS-87 developed for German ecological condit ions, has been adapted to the conditions of two sub-regions in the Slovak R epublic. In particular, the selection of plant varieties used for animal fe eding, the plants' growing cycles and harvests, the animal feeding practice s and the human consumption rates were subjected to adaptation. Measurement s of caesium and iodine radioactivity in soil, plants and animal products t hat have mainly been performed in the vicinity of the Bohunice nuclear powe r plant after the Chernobyl accident, are compared with the results of the adapted model. Data from various locations with dry, mixed or predominantly wet deposition show in general good agreement.
