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.

She reasoned that pitchblende must contain at least one other radioactive element. Curie needed to refine several tons of pitchblende in order to obtain tiny amounts of radium and polonium, another radioactive element discovered by Curie. One ton of uranium ore contains only about 0.14 grams of radium.
