Radioactivity

/ˌreɪdioʊækˈtɪvəti/ noun

Definition

The spontaneous release of energy from atoms as they break apart and transform; a property of certain elements like uranium and radium that emit radiation.

Etymology

From 'radio-' (Latin 'radius,' ray) plus 'activity.' The term was coined by physicist Pierre Curie in 1898 when Marie and Pierre Curie discovered the phenomenon.

Kelly Says

Marie Curie won the Nobel Prize twice for discovering radioactivity, but she died of cancer caused by radiation exposure—her own scientific achievement killed her, which is both tragic and a powerful lesson about the hidden dangers of discovery!
