Proton-Induced X-Ray Emission in the Trace Analysis of Human Tooth Enamel and Dentine

Ahlberg, Mats and Akselsson, Roland LU (1976) In International Journal of Applied Radiation and Isotopes 27(5-6). p.279-290
Abstract
In this study the feasibility of applying proton-induced X-ray emission spectroscopy (PIXE) to the trace element analysis of human tooth enamel and dentine is investigated. Detection limits on the order of 1–10 ppm are obtained. Depth yields for different elements and proton energies are discussed. Enhancement calculations show that the effect for PIXE analysis is less important than for X-ray induced X-ray analysis. However, for elements with an absorption edge just below an intense X-ray line from a major element the enhancement effect is significant, and, due to the 40% calcium in the enamel matrix, it is estimated to be 15% for potassium. The importance of a smooth sample surface is discussed.
