Effect of humic substances on the environmental migration of radionuclides

Migration of radionuclides in environmental media and in engineered barriers has long been studied with the aim to understand and predict the movement of radionuclides from their sources and the environmental effects of radionuclides. Humic substances affect transport of radionuclides either by formation of complexes with radionuclides in water, thereby changing their speciation and behavior in migration (diffusion, dispersion and uptake by solid phase), or by adsorption on the solid phase of the migration medium, whose sorption properties toward radionuclides are thus changed. Quite a number of data were obtained and many papers were published on these phenomena.

The project aims at critical evaluation of the state of art of knowledge in this field. The following main topics will be analyzed:
