Radioactivity removal and transport processes from soil to Adriatic sea water deriving from Chernobyl fall-out deposition

The radionuclide contamination of the Po river valley, the largest Italian area affected by the fallout deposition due to the Chernobyl nuclear accident, may be defined taking into account the extent of radionuclide depositions, the soil sorption characteristics and the successive transfer processes from soil to the Po river system. On the basis of three months investigations to evaluate the fall-out deposition, it was possible to work out the analysis of the radionuclide transfer from soil to surface waters and to verify the laws governing such a process
