Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

X-rays : Man becomes transparent

On December 28, 1895, the German physicist Wilhelm Conrad Röntgen announced he had discovered rays which he called X. With these rays, we can see inside objects, and when the hand is interposed, it is the bones that appear!

For the public, these rays are a source of entertainment. For doctors, they offer a revolutionary technique for exploring the human body. Many of these pioneers who use X-rays are victims of radiation dermatitis, or burns to the hands that, in the most severe cases, lead to amputations and even death.

Regulation of the use of X-rays and implementation of radiation protection measures would not come before the late 1920s.
