Observations following the Chernobyl accident revealed that nutrient cycling and storage leads to a much longer persistence of radionuclides in semi-natural environments in comparison cultivated agricultural land. In 1996 the EC-funded SEMINAT programme was launched to measure and model radionuclide fluxes in forest ecosystems across the European Union. RIFE (Radionuclides in Forest Ecosystems) consists of three models of radionuclide behaviour in forests: one equlibrium distribution model, and two dynamic models with different levels of complexity (SHAW and BELLI 1998). Within this framework besides sites in Germany, Ireland, Italy and the UK, an Austrian Forest site (Weinsberger Wald) was selected for the acquisition of a site-specific data set of radiocaesium fluxes for the calibration of the RIFE model.
