To improve our understanding of the mechanisms governing the transfer of radionuclides to plants, we will apprehend mainly the role of the biological elements (plants, mycorrhiza, microbes) involved in this transfer: radionuclides sorption/desorption in soils and radionuclides uptake/release by the plants. Because of the importance of the chemical nature of the involved radionuclides, we follow the bioavailability of four different radionuclides: caesium, strontium, technetium, and uranium. Exact role of additional pollutants will be scrutinised. To improve existing predictive models of radionuclides contamination of soils, we will incorporate knowledge acquired from the experimental results into 2 mechanistic models. Finally, we will extract from the experimental results some scientific bases for the development of bioremediation methods of radionuclides contaminated soils and apprehend the role of additional non-radioactive pollutants on radionuclide bioavailability.
