The interaction of x-rays with matter and radiation safety if that interaction results in the ejection of an outer orbital electron, this lower energy electron moves into the vacated k-shell resulting in the production of an x-ray photon that leaves the atom. Interaction of radiation with matter 1 fig 3 interaction of photons with matter photon matter photoelectric effect compton scatter pair production high speed electrons matter ionization excitation heat also higher atomic number elements are better for x ray production. However, the interaction of x-rays with matter is more complex than simply 'passing through' on reaching a material, some of the x-rays will be absorbed, and some scattered - if neither process occurs it is this x-ray fluorescence which forms the basis of xrf spectroscopy. They can interact with matter they cause compton effect they are of two types viz hard ray soft x-ray they lie above the x - rays in the electromagnetic spectrum and are distinguishable from the x - rays by the source of their origins.
