Laboratory migration experiments with radionuclides and natural colloids in a granite fracture

摘要

Natural colloids in groundwater could facilitate radionuclide transport, provided the colloids are mobile, are present in sufficient concentrations and can adsorb radionuclides. This paper describes the results of a laboratory migration study carried out with combinations of radionu- clides and natural colloids within a fracture in a large granite block to experimentally determine the impact of colloids on radionuclide transport.
