Introduction
When X-ray radiation from the portable XRF (pXRF) excites atoms in the sample, the atoms release fluorescent X-rays. The energy level of each fluorescent X-ray created is characteristic of the element excited; as a result, one can tell what elements are present. The Bruker Tracer 5 pXRF detects and determines the fluorescent X-ray energies produced. As the pXRF emits radiation (from 4 to 50 kV), a comprehensive knowledge of radiation safety and procedures is needed.
