X-Rays
(Grenz Rays; Roentgen Rays)
Penetrating electromagnetic radiation emitted when the inner orbital electrons of an atom are excited and release energy - in the same energy range as gamma rays (0.010-10 Mev), but of non-nuclear origin, of shorter wavelength than ultraviolet; soft x-rays or Grenz rays are less penetrating and longer in wavelength than hard x-rays.
