Discovery of artificial radioactivity
WebHenry Becquerel discovered radioactivity by accident. A Uranium compound was placed in a drawer containing photographic plates, wrapped in a black paper. When the plates were examined later, it was found that they were exposed! This exposure gave rise to the concept of Radioactive decay. Radioactivity can be seen in such forms WebIn the 1920s, Curie's health began to deteriorate rapidly. While now, it is common knowledge of the noxious nature of radium and the affect radioactivity has on the …
