Summary:
An optical system for detecting the single-shot fluorescence spectrum from a single flowing particle was built. With this system, the single-shot fluorescence spectrum was observed from an individual UO3 particle around 50 um in diameter. The fluorescence spectra from UO2, UO3, U3O8 were centered around 520 nm when excited by a 266 nm or 355 nm laser. The fluorescence spectra from UOx showed different peak wavelengths and different spectral profiles from those of SiO2, Al2O3, CaO, CdO, CrO3, Cr2O3, FeO, Fe2O3, Li2O, PbO, PbO2, and Pb3O4, which could be the main interfering mineral-oxide particles. These differences provide the possibility of a quick and simple method for distinguishing UO2, UO3, U3O8, and other uranium oxide particles from many common mineral-oxide particles. By measuring single-shot, single-particle fluorescence spectra, it also may be possible to monitor the ambient aerosols that are contaminated with uranium oxide in the respiratory size aerosols (1-10 um in diameter).
