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 1896, Fleischman read of Wilhelm Röntgen's breakthrough with x-rays in Vienna, Austria: "A new photographic discovery" which sparked her interest in radiography. [7] [8] In August 1896, she attended a public lecture by and presentation on X-ray apparatus by Albert Van der Naillen in San Francisco. [9]
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.
1896 Wilhelm Conrad Röntgen discovers the X-rays while studying electrons in plasma; scattering X-rays—that were considered as 'waves' of high-energy electromagnetic radiation—Arthur Compton will be able to demonstrate in 1922 the 'particle' aspect of electromagnetic radiation.
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. German physicist Wilhelm Wien derives Wien approximation.
