Uncertainties in nuclear decay data evaluations

International audienceOver the years, scientists have compiled and evaluated experimental results and combined these with theoretical studies with the goal of obtaining the best values, and their uncertainties, for the quantities related to radioactive decay. To meet the demand, an international group, the Decay Data Evaluation Project, was organised in 1995. The methodology adopted by this group is detailed. Some examples are given explaining how the final uncertainties are assessed from the experimental results and their uncertainties
