From Webster's Revised Unabridged Dictionary (1913) [web1913]:
R94ntgen ray \R[94]ntgen ray\ (Physics)       Any of the rays produced when cathode rays strike upon       surface of a solid (as the wall of the vacuum tube).       R[94]ntgen rays are noted for their penetration of many       opaque substances, as wood and flesh, their action on       photographic plates, and their fluorescent effects. They were       called {X rays} by their discoverer, W. K. R[94]ntgen. They       also ionize gases, but cannot be reflected, or polarized, or       deflected by a magnetic field. They are regarded as       nonperiodic, transverse pulses in the ether. They are used in       examining opaque objects, as for locating fractures or       bullets in the human body.
