Determination of the characteristic limits (decision threshold, detection limit and limits of the coverage interval) for measurements of ionizing radiation – Fundamentals and application

Part 4: Guideline to applications

(ISO 11929-4:2020)
Class/Status: Standard, valid
Released: 2021-06
VDE Art. No.: 0400448

This International Standard specifies a procedure, in the field of ionizing radiation metrology, for the calculation of the "decision threshold", the "detection limit" and the "limits of the confidence interval" for a nonnegative ionizing radiation measurand, when counting measurements with preselection of time or counts are carried out, and the measurand results from a gross count rate and a background count rate as well as from further quantities on the basis of a model of the evaluation. The present part 4 gives a practical guideline to the application of the standard series ISO 11929.
