An external beam technique of PIXE for uranium determination in environmental objects

The possibilities of the determination of the content of uranium in materials of the nuclear fuel cycle and environmental objects using the nuclear-physical methods of analysis based on registration of characteristic X-rays excited by protons (PIXE) are considered. It is shown that the introduction...

Zusammenfassung:The possibilities of the determination of the content of uranium in materials of the nuclear fuel cycle and environmental objects using the nuclear-physical methods of analysis based on registration of characteristic X-rays excited by protons (PIXE) are considered. It is shown that the introduction to X-ray emission spectrometer the element with a wave dispersion – a pyrocarbon filter, using Bragg-Wulf reflection from the planes of the crystal lattice, makes it possible to reduce the detection limit of uranium in the presence of interfering impurities to a value of 0.0005 mas.%. The proposed approach can be used to determine Th, Pu, and other actinides.
