Image of Becquerel's photographic plate which has been fogged by exposure to radiation from a uranium salt. Since protons are positively charged and like charges repel, it is clear that protons cannot remain together in the nucleus unless there is a powerful force holding them there. It is, in essence, an attribute of individual atomic nuclei. stream In 1898, Marie and Pierre Curie isolated and discovered the radioactive element in uranium ore that they named radium. The actual composition of the three types of radiation was still not known. A nucleus (with one exception, hydrogen-1) consists of some number of protons and neutrons pulled together in an extremely tiny volume. Vincent P. Guinn, in Encyclopedia of Physical Science and Technology (Third Edition), 2003. It is also possible for scientists to smash nuclear particles together and cause nuclear reactions between normally stable nuclei. Such disintegrations are referred to as natural radioactivity. 242 Compare the energy released per gram of matter in nuclear reactions to that in chemical reactions. In addition, uses for nuclear radiation also emerged quickly—for example, people such as Ernest Rutherford used it to determine the size of the nucleus and devices were painted with radon-doped paint to make them glow in the dark (Figure $$\PageIndex{1}$$). Comptes Rendus Physique - Vol. Henri Becquerel, Marie Curie, and Pierre Curie shared the discovery of radioactivity. endstream One of the crucial steps in the discovery of radioactivity was achieved by Pierre and Marie Curie in 1898, when they demonstrated the presence, in Uranium minerals, of two new elements which they called Polonium and Radium . endobj Shortly after his discovery George Hevesy enunciated the tracer method leading to the application of radioactivity as a tool in the physical and life sciences.
