PhysicsRadioactivity
Quick Answer
Henri Becquerel’s discovery in 1896. He found that uranium salts could fog photographic plates without sunlight.
The Full Story
Henri Becquerel discovered radioactivity in 1896 while investigating phosphorescent materials. He found that uranium compounds emitted penetrating rays on their own, even in the dark. This showed that atoms could spontaneously emit energy, which was a revolutionary idea at the time. Marie and Pierre Curie later expanded the field, but Becquerel is credited with the initial discovery and received the 1903 Nobel Prize in Physics.
