Figure 1
Illustration of the primary radiation-damage mechanisms that occur in samples exposed to X-rays. Photoionization typically initiates the damage by removing an inner-shell electron from an atom. Such a photoionized atom exists in an excited state that can relax via one of two pathways: Auger emission or X-ray fluorescence. The first is more probable for lighter elements, whereas the latter is more probable for heavier elements.
