What did Marie Curie discover about the atom? She discovered radioactivity a term that she coined, which is a condition resulting from changes to the nuclei of atoms. Marie Curies efforts have been monumental in discovering different facets of radioactivity. She defined radium, to be the gamma ray source on x-ray machines. It was later renamed in her honor after World War II. For this reason and because of its comparative cheapness and simplicity, the second of the Curies . Marie Sklodowska Curie (1867 - 1934) was a Polish-born French scientis t, who is one of the most famous women in the field of science.

(Photo ACJC), You can exit this site to an exhibit Curie's pioneering work on the theory of radioactivity and subsequent discovery of radium won her many accolades, but the financial cost of continuing her research on an element that had quickly become popular for its therapeutic properties was a formidable obstacle. For example, a procedure known as Brachytherapy involves the plantation of a small amount of radioactive material in the tumor. They were awarded the Nobel Prize in Physics . Her contributions are not only limited in the laboratory and not many are aware of the important role she played in the First World War. The Curies also found that radium was almost a million times more radioactive than uranium. She shared the prize with Pierre Curie, her husband and lifelong fellow researcher, and with Henri Becquerel. Her work paved the way for the discovery of the neutron and artificial radioactivity. the number of atoms present in the sample. How did Henri Becquerel discover radioactivity? It is presently called Maria Skodowska-Curie Institute of Oncology. In 1902, along with her assistant, Marie Curie was able to successfully isolate a tenth of a gram of pure Radium Chloride from tons of pitchblende mineral. But nobody grasped the complex inner structure or the Thus she theorized correctly that the rays were coming from within uranium atoms and not from a chemical reaction.
