Determination of metal elements concentrations in human brain tissues using PIXE and EDX methods
Abstract:
Post-mortem human brain tissues were investigated using PIXE and EDX methods for the presence of iron and other metal elements. Several different human brain samples were irradiated with 3 MeV proton beam to collect X-ray spectra from which distribution and concentration of Fe, Mn, Cr and Zn in brain tissues were determined using GUPIXWIN software. The concentration of iron in the brain tissues varied from about 60 ng/cm2 to ~ 4 μg/cm2. The EDX method showed only a qualitative presence of Fe, Zn, Al and Si in investigated samples
