Abstract:At the occasion of the Consultants Group Meeting held to review the “International Target Values 2010 for Measurement Uncertainties in Safeguarding Nuclear Material” [3], discussions between experts highlighted the need to improve communication between different safeguards measurement communities, e.g. laboratory analysts, non-destructive assay specialists, safeguards data evaluators, and to reconcile their approaches to estimating measurement uncertainties. The purpose of this paper is to contr ibute to reaching a common understanding of the terminology and methodologies used by different professional groups in the field of uncertainty quantification.
