Nuclide chart - Enhanced knowledge of the elements' radioactivity

Jul 11 2012

An updated edition of the "Karlsruhe nuclide chart" has been published today by the JRC. This chart is an extended periodic table of the elements displaying all known atoms of any element and their radioactive data. An explanatory booklet is available in English, German, French, Spanish, Chinese and Russian. The 8th edition contains new and updated radioactive decay data on 737 nuclides not available in the previous edition, dating from 2007. In total, nuclear data on 3847 nuclides are presented.

This new edition includes the new element names copernicium (symbol Cn element 112), flerovium (symbol Fl, element 114) and livermorium (symbol Lv, element 116), as recently approved by the International Union of Pure and Applied Chemistry (IUPAC). It also provides the most recent values of the atomic weights and isotopes abundances and other various nuclear parameters.

This publication supports the JRC's particular focus on the education and training of present and future scientists and engineers in the nuclear domain, as demanded by the Euratom Treaty. Beyond the more traditional physical sciences such as health physics and radiation protection, nuclear and radiochemistry, and astrophysics, the chart is also widely used in the life and earth sciences (biology, medicine, agriculture, geology, etc.).

Since its first edition in 1958, the Karlsruhe nuclide chart has provided scientists and students with structured, accurate information on the half-lives and decay modes of radionuclides, as well as the energies of emitted radiation.
