UKPADD6.11 - The UK Activation Product Decay Data LibraryRelease NotesThe latest version of the UK Activation Product Decay Data Library (UKPADD6.11) was assembled for general use in March 2012, and is described in the report JEF/DOC-1424 (see below). The decay data of various radionuclides have been evaluated on the basis of a series of well-defined specifications. These radionuclides are predominantly activation products of immediate relevance to the European Fusion Programme and to the operation, decommissioning and disposal of fission-based reactor facilities, along with various standards that are commonly used to calibrate gamma-ray spectrometers. Recommended data include half-lives, branching fractions, alpha, beta and gamma-ray energies and emission probabilities, total decay energies, mean alpha, beta and gamma energies, internal conversion coefficients, internal-pair formation coefficients, and all associated uncertainties. Computer based files have been generated, including lists of the references used to produce the proposed decay schemes and comments that identify any observed inadequacies. The evaluated data have been processed through the COGEND code to yield complete and verified evaluated decay data files in ENDF-6 format. Verification has included processing with the codes STANEF, CHECKR and FIZCON, and confirming the overall consistency of the energy release by summing the emission by quanta and comparing with the total emission by decay mode. All evaluations for UKPADD6.11 were carried out by Dr A.L. Nichols whilst COGEND processing and verification were performed by SERCO. Data for five nuclides have been newly evaluated or re-evaluated for UKPADD6.11 during the course of 2011/12: 36-Kr-90, 37-Rb-90, 38-Sr-94, 53-I-136, 53-I-136M. Contents
