Development of NSC KIPT nuclear microprobe

Development of the microanalysis methods is stimulated by investigations of actual materials. Their properties depend not only on an atomic structure, but also on imperfections of this structure, phase composition, areas of impurity accumulation, various kinds of microinclusions etc. Characteristic sizes of these objects are usually ranged from a few parts of micron to several tens of micron. So, there is need for methods which provide the analysis of chemical elements in samples with the corresponding level of spatial resolution

X,γ,β–spectrometric investigations of Chernobyl “hot particles” nuclide composition

Results of investigation of the radionuclide composition of “hot particles” from Chernobyl “Shelter” Object are discussed. An estimate of radionuclide activity of radioactive pollution levels for some premises of “Shelter” is performed
