A preliminary study of the weathering of uranium oxide particles diluted in diamond dust at ambient environmental conditions is presented. The primary weathering reaction is oxidation of the uranium from the +4 to +6 oxidation state, although formation of compounds such as carbonates and hydroxides is possible. Identification of the state of uranium oxides has been attempted using luminescence spectroscopy and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). Luminescence spectra of nominal samples of three common oxides, UO₃, U₃O₈, and UO₂, have been measured showing significant spectral differences in peaks at 494 nm, 507 nm, 529 nm, and 553 nm. DRIFTS spectra of the same three oxides show significant differences in peaks at 960 cm⁻ , 856 cm⁻ , and 756 cm⁻ . The differences in these peaks will allow determination of the oxidation to the +6 state in these compounds.
