Today, we talk about radioactivity and radioactive elements. But do you know who coined the term 'radioactivity''? Yes, it was the Nobel Prize winning Marie Curie. She discovered two important elements - Radium and Polonium, which you will be able to easily spot in the periodic table. Marie Curie dedicated her entire life for research on radioactive elements.
Frederic Joliot-Curie and Irene Joliot-Curie were both French scientists. Husband and wife, they were jointly awarded Nobel laureates in 1935 for their joint discovery of new radioactive isotopes which they prepared artificially. They are also known for their contribution towards the discovery of the neutron.
Irene Joliot-Curie and Frederic Joliot Curie jointly discovered artificial radioactivity. These isotopes rapidly became important tools in biomedical research and in the treatment of cancer and related diseases.
