Description
This teaching unit aims to better understand the chemical behavior of radionuclides under environmental conditions. To this end, the notion of speciation in different environmental compartments will be introduced, as well as the different techniques allowing to contribute to the global analysis. A focus will be put on X-ray absorption, X-ray fluorescence imaging, transmission electron microscopy and SIMS. Speciation results will then be correlated to potential environmental impacts.

CM : 12h
TD : 8h
Objectives
The objective of this teaching unit is to understand the chemical behavior of radionuclides in the environment by studying their speciation by different techniques. It will allow to evaluate the environmental impact linked to the presence of radionuclides in different compartments of the environment.
Necessary pre-requisites
Solution chemistry applied to actinides
Knowledge control
Continuous control
Syllabus
- Definition of the issues related to measurement under environmental conditions
- Actinide speciation:
- Definitions, issues and measurement implications
- Examples of actinide speciation under environmental conditions (redox, hydrolysis, complexation)
- Examples of speciation in complex media
- Techniques associated with the study of speciation under environmental conditions
- Molecular speciation by X-ray absorption
The lectures and tutorials will be supplemented by group case studies and bibliographic tutorials on real cases.
