Marie Curie and the Discovery of Radium
نویسنده
چکیده
Marie Curie gave outstanding contributions to science and society that were recognized still in her lifetime. In particular, the discovery of radium completely changed the therapeutic methods for treatment of cancer and other diseases, and allowed the development of radiotherapy and nuclear medicine. Radium was also used in many non-medical applications. Radium applications fostered the growth of uranium mining industry during the first half of 20th century. During the second half of the past century, with developments of artificial radionuclides production and particle physics, radium was gradually replaced by shorter-lived radionuclides and electron and photon beams in cancer therapy. In the 70s and 80s most radium sources in cancer hospitals were replaced while in non-medical applications radium had been substituted already. Notwithstanding, the avenue for medical use of radioactivity and radionuclides opened with Marie Curie discoveries and radium applications still goes on. This avenue is currently pursued in curietherapy and nuclear medicine.

متن کاملPierre Curie, 1859–1906
The year 2006 marked 100 years since the death of Pierre Curie. It is therefore appropriate that we remember his life and his work, which was cut short by his untimely death from an accident on the Pont Neuf, Paris, on April 19, 1906. He had already accomplished much during his life, both before the discovery of radium with Marie Curie, in work co-authored with his brother Jacques on piezoelect...

At the end of 19th century a few fundamental discoveries changed diagnostic and therapeutic possibilities in medicine and, particularly, in oncology: in 1895 Wilhelm Roentgen from Germany discovered X-rays, in 1886 Henry Becquerel described the phenomenon of radioactivity of uranium, and in 1898 Marie and Pierre Curie discovered radium and polonium. In 1903 the Nobel Prize for Physics was award...
