what day was radioactivity discovered
This discovery of spontaneous âradioactivityâ (a term coined by Becquerelâs doctoral student, Marie Curie) eventually earned Becquerel a Nobel Prize for Physics in 1903, which he shared with Marie Curie and her husband Pierre Curie.enchmarks: Henri Becquerel discovers radioactivity on February 26, 1896.
