As per X-ray Fluorescence theory, when material particle is irradiated with X-ray the electron of innermost orbital of that element atom is exited and emits outside of the atom as photoelecrons, living behind a hole in innermost orbital . This hole is filled by outer orbital electrons. The question is that finely what happens to that photo electon which is emitted outside of the atom?
