Physics - Radioactivity: The Discovery of Radioactivity

This is the 1st lesson in the series, "Radioactivity." This lesson traces the historical journey leading up to the discovery of radioactivity by Becquerel and the isolation of radioactive isotopes by the Curies. It also considers why some isotopes undergo decay and examine alpha, beta and gamma decay. Examples of nuclear reactions are also given to show the relationship between parent and daughter atoms.
