Data requirements for neutron activation: Part II: Decay data

Existing data libraries such as EAF-2003 contain information for a large number of nuclides. Of these only a proportion makes a significant contribution to quantities such as activity or γ-dose rate at various decay times. These nuclides were identified in a recent extensive set of calculations on all the elements and reported in the ‘Activation Handbook’. These 754 nuclides are considered here and the set of nuclides judged to have poorly known decay data are listed and prioritised. A set of 338 prioritised nuclides are given and the most important of these are recommended for measurement and evaluation work in the foreseeable future.
