Résumé

Predicting the behavior and reactivity of radioactive "hot" particles in the geosphere requires their thorough characterization, if possible in their native environment. Research progress on Pu(IV) colloids is particularly challenging because of the complex chemistry of the element Pu and the high radioactivity of all of its isotopes. Within this framework, researchers from Marcoule Institute for Separation Chemistry (ICSM), CEA/DMRC and SOLEIL/MARS beamline, have combined synchrotron SAXS (Small Angle X-ray Scattering) and XAS (X-ray Absorption Spectroscopy) techniques to decipher the multi-scale structural properties of Pu(IV) intrinsic colloids prepared by hydrolysis or sonolysis.
