What was discovered

Becquerel observes that uranium salts emit spontaneous radiation; Marie Curie shows that it is an atomic property, coins 'radioactivity' and, with Pierre, isolates polonium and radium by chemically separating tonnes of pitchblende.

Nobel Prize in Physics 1903, shared; Marie Curie, Nobel Prize in Chemistry 1911.
