Evaluation of Cu in hepatocellular carcinoma by particle induced X-ray emission

Journal of Trace Elements in Medicine and Biology, 2007
copper, zinc, iron, and other nine trace elements (TEs) in 30 patients with hepatocellular carcinoma (HCC) were determined from the HCC itself and the surrounding liver parenchyma (SLP) using particle induced X-ray emission (PIXE). The result showed that the level of Zn, Fe, Co, Ca, Mn, Rb, and Cl in HCC significantly differed from that in the SLP ...

Analytical Applications Of Particle-Induced X-Ray Emission (PIXE)

AIP Conference Proceedings, 2007
In this paper a complex study of the capabilities of Particle‐Induced X‐ray Emission (PIXE) technique for the determination of major, minor and trace constituents of metallurgical, biological and environmental samples has been done. The elements identified in the metallurgical samples (steels) using PIXE were: K, Ca, V, Cr, Mn, Fe, Co, Cu, Ni, Zn, W ...

A REVIEW OF PARTICLE-INDUCED X-RAY EMISSION IN GEOLOGY

International Journal of PIXE, 1991
Particle-induced X-ray emission is very well suited for the analysis of geological samples. This review discusses the characteristics for such analyses. For light-element analysis, the complimentary technique of particle-induced gamma ray emission is also discussed since the emission of gamma rays occurs simultaneously with the X-rays.

Angular distribution of particle-induced X-ray emission

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1984
Abstract The angular distribution of the continuum radiation in the energy range 2–15 keV for angles 30–160° has been investigated, both experimentally for 1.5, 2, 3, and 4 MeV protons on Al, and theoretically for secondary electron bremsstrahlung, emphasizing the electron bremsstrahlung angular distributions.

Analytical application of particle induced X-ray emission

Nuclear Instruments and Methods, 1976
This review article deals with the X-ray emission induced by heavy, charged particles and the use of this process as an analytical method (PIXE). The physical processes involved, X-ray emission and the various background reactions are described in some detail. A theoretical discussion of the sensitivity is given. Experimental arrangements are described

Surface sensitive particle-induced X-ray emission

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2002
A technique for quantitative and non-destructive surface spectroscopy using charged particle X-ray production at grazing exit angles is described. The enhanced surface sensitivity derives from: (i) the effect of refraction which increases the probability for emission near the critical angle, and (ii) self-absorption for those photons emitted at depth ...
