German scientist discovers X-rays. On this day in 1895, physicist Wilhelm Conrad Rontgen (1845-1923) becomes the first person to observe X-rays, a significant scientific advancement that would ultimately benefit a variety of fields, most of all medicine, by making the invisible visible.
Medical x-ray machines in hospitals use the same principle as the Crookes Tube to produce x-rays. The most common x-ray machines use tungsten as there cathode, and have very precise electronics so the amount and energy of the x-ray produced is optimum for making images of bones and tissues in the body.Here is a good page that shows how x-rays are formed. 1  Go on to page 7. 2  Go back to page 5.3  Return to the table of contents. 4  Return to the Radiation Information Network's HomePage.ere is a good page that shows how x-rays are formed. 1  Go on to page 7. 2  Go back to page 5. 3  Return to the table of contents. 4  Return to the Radiation Information Network's HomePage.
