50 years of the Karlsruhe Nuclide Chart
The Karlsruhe Nuclide Chart, a form of extended periodic table of the elements that displays all known atoms of any element and their radioactive data, is 50 years old today. To celebrate the occasion, the JRC Institute for Transuranium Elements (ITU) in Karlsruhe is hosting selected guests including Members of European Parliament, politicians and Nobel prizes laureates, for a discussion of its history and use since its creation in 1958. The event will also serve as the launch of a book specially prepared for the chart's anniversary.
The first edition of the Karlsruher Nuklidkarte was edited in 1958 by Walter Seelmann-Eggebert together with Gerda Pfennig (who was also involved in the current edition) at what was to become today’s Forschungszentrum Karlsruhe, which hosts JRC-ITU.
The latest (7th) edition, published in 2006, contains new and updated radioactive decay data on 618 nuclides not found in the previous (1998) edition. In total, nuclear data on more than 2962 experimentally observed nuclides and 692 isomers are presented.
What are nuclides and why do we chart them?
The Karlsruhe Nuclide Chart has provided scientists and students all over the world with structured, accurate information on the half-lives and decay modes of radionuclides, as well as the energies of emitted radiation. In science, the term nuclide is used to categorise an atom (stable or unstable) characterised by the number of protons and the number of neutrons in its nucleus. All isotopes of an element contain the same number of protons but different numbers of neutrons in the nucleus. Nuclide charts hence offer a full description of the radioactive attributes of an element and its isotopes, providing a unique overview of current knowledge in nuclear science.
The chart is used today in health physics and radiation protection, nuclear and radiochemistry, astrophysics and life and earth sciences (biology, medicine, agriculture, geology, etc.)
