Today, 117 years after the Curiesâ discovery of Radium, even the public is kept well aware of the potential dangers associated with the exposure of the human body to radioactive elements. Yet, from the very first years during which the scientists and their contemporaries were pioneering the study of radioactivity until the mid 1940s, little was concretely understood about both short and long-term health effects.
Radium was discovered in 1898 by Marie Curie and Pierre Curie. They managed to extract 1 mg of radium from ten tonnes of the uranium ore pitchblende (uranium oxide, U 3 O 8), a considerable feat, given the chemically methods of separation available to them.
