	Roentgen - MSN Encarta
		Roentgen's discovery of X rays was a momentous advance for physics and medicine and earned him the 1901 Nobel Prize in physics.
		Roentgen worked as a laboratory assistant at the University of Würzburg in Germany from 1868 to 1872 and at the University of Strasbourg in Germany from 1872 to 1874.
		Roentgen was using a Crookes tube without an aluminum window and he had surrounded the tube in fl cardboard to better see the tube glow.

		Roentgen called them "X-rays" because their nature was so puzzling, but others were soon calling them Roentgen rays, and he won the very first Nobel prize for physics in 1901.
		Even Roentgen's famous X-ray image of his wife's hand, which he conceived as a sort of tribute, "actually frightened her terribly," according to a Roentgen biographer.
		Roentgen's brilliance was in seizing on a chance observation and recognizing what it meant -- for which he won the Nobel.

	Roentgen And The Disovery of X-Rays
		Roentgen was interested in cathode rays and in assessing their range outside of charged tubes.
		To Roentgen's surprise, he noted that when his cardboard-shrouded tube was charged, an object across the room began to glow.
		Roentgen, who won the first Nobel prize in physics in 1901, declined to seek patents or proprietary claims on the X-rays, even eschewing eponymous descriptions of his discovery and its applications.

		On this date Dr. Roentgen sent copies of his manuscript and some of his x-ray photographs to several renowned physicists and friends.
		Professor Roentgen uses the light emitted from one of Crookes' vacuum tubes, through which an electric current is passed, to act upon an ordinary photographic plate.
		After a discussion of his experiments, Dr. Roentgen invited Dr. Albert von Kolliker, a famous anatomist, who was chairing the session, to have his hand photographed with the new rays.

		An acronym for Roentgen Equivalent Man. A unit which measures radiation in terms of the energy involved (the same as RAD), weighted by a factor related to the type of radiation.
		A unit of biological dose of radiation; the name is derived from the initial letters of the term "roentgen equivalent man (or mammal)." The number of rems of radiation is equal to the number of rads absorbed multiplied by the RBE of the given radiation (for a specified effect).
		Roentgen equivalent man, a unit used in radiation protection to measure the amount of damage to human tissue from a dose of ionizing radiation.

		The roentgen was defined by the 1937 Radiological Congress (Chicago) as the amount of x-radiation or gamma radiation that produces ionization equal to 1 electrostatic unit of charge, either negative or positive, in 1 cubic centimeter of dry air at 0°C and at standard atmospheric pressure.
		At a meeting of the BIPM’s working group for the measurement of X- and gamma-rays in 196X, the roentgen was redefined as 2.58 × 10
		coulomb per kilogram of air, and the symbol as R. Although the roentgen has been discontinued in favor of expressing such measurements in coulombs per kilogram, the CIPM has sanctioned its temporarily continued use.
