Discovered Spontaneous Radioactivity

In 1897 when Henri Becquerel researched the newly discovered X-rays it led to studies of how uranium salts are influenced by light. By accident, he discovered that the uranium salts spontaneously emitted a penetrating radiation that could be registered on a photographic plate. Further studies made it clear that this radiation was something new - not the same type as X-rays. He had discovered a new phenomenon - radioactivity.
