Page contents Page contents Course objective The objective of this course is to explain how to use the Karlsruhe Nuclide Chart (KNC), what types of data are presented, and how to interpret its characteristic colour-coding system.The course is intended for students and professionals working with radionuclides. The KNC provides scientists and students with comprehensive nuclear data on all experimentally observed nuclides, including ground states and isomers, as well as the most recent values of atomic weights, isotopic abundances, and cross sections.The chart has strong didactic value and is widely used for education and training in nuclear sciences.See the Karlsruhe Nuclide Chart on the Nucleonica website. Scope The course consists of lectures and a practical session.The lectures cover the following topicsstable and radioactive nuclides and decay modesisotopic abundancescolour codes in the chart and decay chainshalf-life and radiation datathermal neutron cross-section datamass-chain fission yield datareduced decay schemessources of nuclear data Course organisation The Karlsruhe Nuclide Chart training can also be integrated into other nuclear-related courses offered by the JRC (e.g. gamma spectrometry, nuclear security) upon request.The duration of the training is approximately 2 hours.OrganiserThe course is delivered by the European Commission Joint Research Centre (JRC), Nuclear Science and Innovation for Energy and Health Unit (G.5).Course LanguageEnglishContactFor further information contact: Zsolt [dot] Sotiec [dot] europa [dot] eu (Zsolt[dot]Soti[at]ec[dot]europa[dot]eu) Latest edition of the Karlsruhe Nuclide Chart The Karlsruhe Nuclide Chart presents nuclear data for approximately 4 200 experimentally observed nuclides, including the most recent values of atomic weights, isotopic abundances and cross sections.It provides structured and reliable information on radionuclide half-lives, decay modes, and the energies of emitted radiation.Beyond its traditional use in physical sciences, such as health physics, radiation protection, nuclear and radiochemistry, and astrophysics, the chart is now widely used in life and earth sciences. It also offers significant didactic value for education and training in nuclear sciences.The online edition of the Karlsruhe Nuclide Chart and printed versions are available on the Nucleonica website.
