Estimation of the oxidation state of uranium in microparticles by using scanning electron microscope in the backscattered electrons mode

This paper considers the results of applying of scanning electron microscopes in the backscattered electron mode for the specifying of the contents of multielemental samples and minerals, which are presented in publications. This approach is used for estimation of oxidation state of uranium in microparticles. The possibility of this goal achieving is demonstrated on the example of the analysis of the UO2 and U3O8 microparticles and the samples of In, Sn, Pt and Pb.
