Abstract

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.
