Abstract

This paper explains the derivation and application of uncertainty in measurement and related characteristic limits, including decision threshold, detection limit, and upper and lower limits of coverage interval, for low radioactive concentration measurement according to ISO 11929. These concepts are organized especially for clearance measurement, which is performed to evaluate materials to be released from control as radioactive waste.
