We have successfully completed a proof-of-concept, one-year grant on a three-year proposal from the former NABIR program. Using a state-of-the-art 300-kV, atomic resolution, Field Emission Gun Transmission Electron Microscope (TEM), we have successfully identified three categories of mineral hosts for uranium in contaminated soils from the Oak Ridge FRC: (1) iron oxides: (2) mixed manganese-iron oxides; and (3) uranium phosphates.
