چکیده انگلیسی
The purpose of the work presented here was to find the optimal conditions for micro-PIXE analysis of Ti in thin skin sections. In the skin region where Ti is expected to be found, the naturally occurring major elements phosphorus, chlorine, sulphur and potassium have steep gradients and thus influence the X-ray background in a non-predictable manner. Based on experimental studies of Ti-exposed human skin sections using proton energies ranging from 1.8-2.55Â MeV, the corresponding PIXE detection limits for Ti were calculated. The energy that was found to be the most favourable, 1.9Â MeV, was then selected for future studies.
