X-rays (aka Röntgen rays, after their discoverer Wilhelm Conrad Röntgen) are an ionizing type of electromagnetic radiation in the frequency range of 3×1016Hz to 3 × 1019Hz. They can be divided into the more energetic hard x-rays (3×1018Hz to 3 × 1019Hz) adjacent to gamma rays, and into soft x-rays (3×1016Hz to 3 × 1018Hz), adjacent to ultraviolet light. They are widely used for structural investigations in all parts of materials science, though care has to be exerted for uses on living tissue, since ionizing radiation can cause cell damage.
