Mineral and colloid surface phenomena in the final disposal of radioactive wastes

When assessing the safety of final disposal sites for radioactive wastes, the transport of radionuclides in groundwater must be evaluated. Adsorption onto the walls of water-conducting fractures and microfractures is an important factor in farfield radionuclide transportation. Adsorption mechanisms, various adsorption models, adsorbent surface characterization and colloids are examined particularly from the perspective of the final disposal of radioactive wastes. The report also covers factors associated with the use of the commonly applied mere distribution coefficient, the applicability of actual adsorption models, the problems caused by natural materials, the difficulties of experimental laboratory work and the sorption of colloidal particles on solid surfaces
