A penetrating electromagnetic radiation, usually generated by accelerating electrons to high velocity and suddenly stopping them by collision with a solid body, or by inner-shell transitions of atoms with atomic number greater than 10; their wavelength ranges from about 10(-5) angstrom to 10(3) angstroms, the average wavelength used in research being 1 angstrom.
