Special attention is given to his work in life science which he had done in the second half of his scientific career and was the base of the development of nuclear medicine. Keywords: George de Hevesy; Radionuclides; Nuclear Medicine Introduction George de Hevesy has founded Radioanalytical Chemistry and Nuclear Medicine, discovered the element hafnium and first separated stable isotopes. He was an inventor in many disciplines and his interest was not only focused on the development and refinement of methods, but also on the structure of matter and its changes: atoms, molecules, cells, organs, plants, animals, men and cosmic objects. He was working under complicated political situation in Europe in the 20th century. During his stay in Germany, Austria, Hungary, Switzerland, Denmark, and Sweden he wrote a lot papers in German. In 1962 he edited a large part of his articles in a collection where German papers are translated in English [1].

    Nuclear Science—A Guide to the Nuclear Science Wall Chart ©2018 Contemporary Physics Education Project (CPEP) Appendix E Nobel Prizes in Nuclear Science Many Nobel Prizes have been awarded for nuclear research and instrumentation. The field has spun off: particle physics, nuclear astrophysics, nuclear power reactors, nuclear medicine, and nuclear weapons. Understanding how the nucleus works and applying that knowledge to technology has been one of the most significant accomplishments of twentieth century scientific research. Each prize was awarded for physics unless otherwise noted.

In 1996 the Editors of Radiochimica Acta brought out a special volume of the journal to celebrate the hundredth anniversary of the discovery of radioactivity [1]. On the occasion of the 50th anniversary of Radiochimica Acta, which follows closely upon the centenary of Marie Curie’s second Nobel Prize in 1911, the author has the privilege to informally review “Radiochemistry and Nobel Prize Awards”, including discoveries of radioelements and new fields in chemistry based on radiochemical methods. 1.

    List of Nobel laureates 1 List of Nobel laureates The Nobel Prizes (Swedish: Nobelpriset, Norwegian: Nobelprisen) are awarded annually by the Royal Swedish Academy of Sciences, the Swedish Academy, the Karolinska Institute, and the Norwegian Nobel Committee to individuals and organizations who make outstanding contributions in the fields of chemistry, physics, literature, peace, and physiology or medicine.[1] They were established by the 1895 will of Alfred Nobel, which dictates that the awards should be administered by the Nobel Foundation. Another prize, the Nobel Memorial Prize in Economic Sciences, was established in 1968 by the Sveriges Riksbank, the central bank of Sweden, for contributors to the field of economics.[2] Each prize is awarded by a separate committee; the Royal Swedish Academy of Sciences awards the Prizes in Physics, Chemistry, and Economics, the Karolinska Institute awards the Prize in Physiology or Medicine, and the Norwegian Nobel Committee awards the Prize in Peace.[3] Each recipient receives a medal, a diploma and a monetary award that has varied throughout the years.[2] In 1901, the recipients of the first Nobel Prizes were given 150,782 SEK, which is equal to 7,731,004 SEK in December 2007. In 2008, the winners were awarded a prize amount of 10,000,000 SEK.[4] The awards are presented in Stockholm in an annual ceremony on December 10, the anniversary of Nobel's death.[5] As of 2011, 826 individuals and 20 organizations have been awarded a Nobel Prize, including 69 winners of the Nobel Memorial Prize in Economic Sciences.[6] Four Nobel laureates were not permitted by their governments to accept the Nobel Prize.

    GEORGE DE HE V E S Y Some applications of isotopic indicators Nobel Lecture, December 12, 1944 The method of isotopic indicators had its ultimate origin in the Institute of Physics at the University of Manchester, which then was under the inspiring leadership of that great physicist the late Lord (then Professor) Ernest Rutherford. The cradle of radium is the Czecho-Slovakian town Joachimstal; it was from Joachimstal pitchbl en de ore that Professor and Madame Curie isolated that element. The Austrian Government, the owners of these mines, gener- ously supplied Professor Rutherford not only with radium, but also with the by-products of radium production, equally important for the worker in the field of radioactivity. One of the most significant by-products is radium D, which has a half-life period of 20 years and is found associated with the very substantial amounts of lead present in pitchblende. The Austrian Govern- ment presented to Professor Rutherford several hundred kilograms of such "radio-lead". In view of its association with very large amounts of lead, which absorb the radiation emitted by radium D, this precious radioactive material nevertheless proved to be almost useless. When I met Professor Rutherford one day in 1911 in the basement of the laboratory where the radio-lead was stored, he addressed me in his friendly and informal way, saying: "My boy if you are worth your salt, you try to separate radium D from all that lead". In those days, I was an enthusiastic young man and, on immediately starting to attack the problem suggested to me, I felt quite convinced that I would succeed.

Jamir Governor, Odisha Raj Bhawan Bhubaneswar-751 008 August 13, 2013 EMSSSEM I am glad to know that the School of Chemistry, Sambalpur University, like previous years is organizing a Seminar on "Nobel Prize" on August 24, 2013. The Nobel Prize instituted on the lines of its mentor and founder Alfred Nobel's last will to establish a series of prizes for those who confer the “greatest benefit on mankind’ is widely regarded as the most coveted international award given in recognition to excellent work done in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace. The Prize since its introduction in 1901 has a very impressive list of winners and each of them has their own story of success. It is heartening that a seminar is being organized annually focusing on the Nobel Prize winning work of the Nobel laureates of that particular year. The initiative is indeed laudable as it will help teachers as well as students a lot in knowing more about the works of illustrious recipients and drawing inspiration to excel and work for the betterment of mankind. I am sure the proceeding to be brought out on the occasion will be highly enlightening.

    Radioactivity

    Radioactivity Lecture 3 The Discovery of Radioactivity Science and Applications First Indications of new Phenomena • Henri Becquerel discovered 1896 that Uranium blackens a photographic film or silver-photo emulsion. He concluded that there must be a kind of unknown light • Marie and Pierre Curie looked for other materials that may emit this new kind of light. They found Pitchblende. They discovered a time dependence of the emitted radiation and a change of nature of radiation that they saw as indication for new elements, Radium and Polonium, which they extracted by chemical methods. • They developed new experimental methods to detect radiation, they coined the term Radioactivity and introduced a unit for the intensity “Curie”, which represents the number of emitted radiation by 1 g of Radium. It corresponds to 3.71010 events/s, but says nothing about the origin or nature of the radiation. Observations • Radioactivity produces heat (decay heat) • Radioactivity can emanate as gas (Radon) • Radioactivity darkens chemical emulsions • Radioactivity generates fluorescence • Radioactivity generates thermoluminescence • Radioactivity causes chemical reactions • Radioactivity causes burns and other physiological changes • Radioactivity can kill (bacteria, mice) • Radioactivity is temperature independent Discovery Conclusions Curies expectation and explanation of chemical conversion Four times higher activity than Uran, suspicion was there must be something else, a different element? Pitchblende Uraninite UO2 The Curie analyzed and converted several tons of Pitchblende a highly radioactive material that was a left-over from uranium mining. A tedious chemical effort to extract Radium and Polonium as decay products from the Uranium in the material. During that process they were exposed to enormous amounts of radiation, still observed on their notes, working and living quarters, even in the kitchen.
