History of Radioactivity Timeline

(1896 - Present)

The history of radioactivity traces the discovery and understanding of spontaneous radiation emitted by certain elements. Beginning with Henri Becquerel's accidental discovery of uranium rays in 1896, the field expanded rapidly through the pioneering work of Marie and Pierre Curie, Ernest Rutherford's identification of alpha and beta particles, and later developments in nuclear fission, leading to applications in medicine, energy, and weapons.

Key Facts

  1. Henri Becquerel discovered natural radioactivity in 1896 when he found that uranium salts emitted rays that could expose photographic plates without sunlight.
  2. Marie and Pierre Curie discovered the radioactive elements polonium and radium in 1898, and Marie Curie coined the term 'radioactivity.'
  3. Ernest Rutherford identified alpha and beta radiation in 1899 and gamma rays were characterized shortly after, establishing the three main types of radioactive emissions.
  4. In 1934, Irène Joliot-Curie and Frédéric Joliot-Curie produced the first artificial radioisotope, opening the door to synthetic radioactive materials.
  5. The discovery of nuclear fission by Otto Hahn, Lise Meitner, and Fritz Strassmann in 1938 transformed radioactivity research into nuclear physics applications, including reactors and atomic energy.
