On December 28, 1895, the German physicist Wilhelm Conrad Roentgen announced that he had just discovered something which he had baptized X-rays. With these rays, we can see the inside of objects, like bags and suitcases, but if you put your hand in front of them, 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. Despite some warning, the pioneers of radiology were using X-rays without really suspecting the danger in which they were putting themselves. Many fell victim to radiodermatitis – hand burns – which lead to amputations and even death in the most serious cases.
Regulation of the use of X-rays and implementation of radiation protection measures would not come before the late 1920s.
