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. [1] [2] [3]

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 ...
Taking an X-ray image with early Crookes tube apparatus, late 1800s. Radiography's origins and fluoroscopy's origins can both be traced to 8 November 1895, when German physics professor Wilhelm Conrad Röntgen discovered the X-ray and noted that, while it could pass through human tissue, it could not pass through bone or metal.

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.
