PIXE-analysis of powder and liquid uranium-bearing samples

The article concerns techniques of sample preparation from powder and liquid uranium-bearing materials for the PIXE analysis. Experiment procedure is described for elemental analysis of samples with proton induced X-ray emission. Advantages, disadvantages, and restrictions for successive X-rays filters for PIXE spectra are enlisted. Results of a quantitative analysis of the samples are reported. Their credibility is proved by analysis performed for a standard liquid sample.
