The application of the Guide to Uncertainty in Measurements in safeguards

Project ID: PA 73
Funded under: FP5-JRC

Abstract

Since the "Guide to the Expression of Uncertainties in Measurements" (GUM) was published in 1993, the application of the new uncertainty concept has spread widely in the analytical chemistry community. Its acceptance in the nuclear field in general has been more hesitant however, despite a long history of accurate measurements in this area. The definition of uncertainty given in the GUM is associated with the measurement or the measurement process and recognises that the uncertainty of a measurement is an integral part of the measurement result. We find a change in emphasis in the GUM away from evaluation of measurement errors through repeated measurements at the same or different laboratories, towards the evaluation of a single measurement by the compilation and addition (by the propagation of uncertainties) of the individual uncertainty components in the measurement process.
