On the late Friday evening of 8. November 1895, Röntgen discovered for the first time the rays which penetrate through solid materials and gave them the name X-rays.He presented this in a lecture and publication On a new type of rays - Über eine neue Art von Strahlen on 23 January 1896 at the Physical Medical Society of Würzburg.

Unprotected experiments in the U.S. in 1896 with an early X-ray tube (Crookes tube), when the dangers of radiation were largely unknown.[1]The history of radiation protection begins at the turn of the 19th and 20th centuries with the realization that ionizing radiation from natural and artificial sources can have harmful effects on living organisms.
On 11 January 1896 he made the first use of X-rays under clinical conditions when he radiographed the hand of an associate, revealing a sterilised needle beneath the surface. [4] A month later on 14 February he took the first radiograph to direct a surgical operation. He also took the first X-ray of the human spine.
Macintyre's X-Ray Film is an 1896 documentary radiography film directed by Scottish medical doctor John Macintyre. The film shows X-ray images of a frog's knee joint and an X-ray radiograph of an adult's heart and digestive tract (using bismuth as contrast). Each image was captured in 1/300th of a second.
Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
On January 27, 1896, Wright produced an X-ray photograph, barely a month after Wilhelm Röntgen's seminal paper On A New Kind Of Rays was published on December 28, 1895. This was the first X-ray image produced in the country. [9] He contributed numerous scientific papers, chiefly on astronomical and electrical subjects, to various publications.
