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.
In early 1896, there was a wave of excitement following Wilhelm Conrad Röntgen's discovery of X-rays on 5 January. During the experiment, Röntgen "found that the Crookes tubes he had been using to study cathode rays emitted a new kind of invisible ray that was capable of penetrating through black paper". [9]
[10] [11] Fleischman quickly exhibited a keen interest and became proficient with the various apparatus that were necessary to produce the X-rays. By 1897, one year after the discovery of X-rays by Röntgen, she had established an X-ray laboratory on Sutter Street in San Francisco. [12] There she examined patients on behalf of local physicians.
Wilhelm Conrad Röntgen (/ ˈ r ɛ n t ɡ ə n,-dʒ ə n, ˈ r ʌ n t-/; [4] German: [ˈvɪlhɛlm ˈʁœntɡən] ⓘ; often rendered Roentgen in English; 27 March 1845 – 10 February 1923) was a German physicist, [5] who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the inaugural ...
January 12 – H. L. Smith takes the first X-ray photograph. March 1 – French physicist Henri Becquerel discovers the principle of radioactive decay when he exposes photographic plates to uranium .
He opened the first x-ray laboratory in the United States in Chicago, and had completed over 1400 x-ray examinations by 1896. His work was critical to the history of radiation protection. [citation needed] He was the father of Arthur Wolfram Fuchs (1895 - 1962), the inventor of the fixed kilovoltage technique of radiography.
