A REVIEW ON THE POSSIBLE ROLE OF ORGANIC SPECIES IN THE GROUND WATER ON THE MIGRATION BEHAVIOUR OF RADIONUCLIDES IN THE GEOSPHERE IS REQUIRED.
CONSIDERABLE AMOUNTS OF DATA ARE AVAILABLE. THEY ARE, HOWEVER, RATHER SCATTERED THROUGHOUT THE LITERATURE.
AN EXPERIMENTAL STUDY AS WELL AS THEORETICAL CONSIDERATIONS IN THE INFLUENCE OF ORGANIC COMPLEXING AGENTS ON THE SORPTION, AND HENCE MIGRATION BEHAVIOUR OF RADIONUCLIDES ARE OF FUNDAMENTAL INTEREST IN ATTEMPTS TO EVALUATE THE POSSIBLE TRANSPORT OF RELEASED RADIOACTIVE WASTE WITH GROUND WATER.
CHARACTERIZATION OF NATURALLY OCCURRING ORGANICS, E.G. HUMIC AND FULVIC ACIDS IS OF GENERAL INTEREST DUE TO THESE POLYMERIC SPECIES OMNIPRESENCE IN THE TERRESTRIAL ENVIRONMENT AND TO THEIR KNOWN COMPLEXING ABILITIES TOWARDS METAL IONS.
B.1. REVIEW OF AVAILABLE LITERATURE ON THE INFLUENCE OF ORGANIC COMPOUNDS INCLUDING EXPERIMENTAL AND THEORETICAL DATA OBTAINED AT RISO
B.2. BATH-TYPE EXPERIMENTS TO ELUCIDATE THE INFLUENCE OF ORGANICS ON RADIONUCLIDE SORPTION
B.3. COLUMN-TYPE EXPERIMENTS TO ELUCIDATE THE INFLUENCE OF ORGANICS ON RADIONUCLIDE MIGRATION
