Decay data sublibrary

The decay data sublibrary provides the evaluated nuclear data on decay reactions for 4,071 nuclides from neutron and H-1 (Z=1) to Og (Z=118). This data can be used to evaluate the production of radioactive isotopes (RIs) for use in decommissioning nuclear reactors, as well as in wider applications, e.g. the estimation of RI production by accelerators.
