Comprehensive X-ray analysis of foreign bodies in the human tissues

Abstract

For the first time, a complex of X-ray methods: XRD, XRF absorption analysis and the Compton scattering method – was used to study foreign bodies in human tissues. The surface of the fragments on opposite sides was visually significantly different: on one side it was smooth, on the other – rough. At the same time, no differences in the structure of the crystal lattice and the composition of the main impurities were revealed by the XRD and XRF methods. Both methods certified the material of the objects as aluminum alloy AMC. The Compton scattering method showed a change in the effective atomic number of the surface: Zeff =13.15±0.55 on the smooth side and Zeff =11.27±0.46 on the rough side, which corresponds to aluminum (Zeff=13) and its oxide Al2O3 (Zeff=10). The thickness of the oxide layer of 4 μm was determined by the absorption of the Al-Kα line. The fluorescence emission spectrum of the rough side revealed the Br-Kα line. It has been suggested that it is the increased bromine content (20-50 ppm) that promotes additional formation of sulfylamine to increase the tensile strength of the collagen IV molecular corset. This leads to accelerated restoration of the architecture of the cell basement membrane and tissue development.
