The uncertainty covered by the CMC is the expanded uncertainty with a coverage probability of approximately 95 %. The value expressed as a percentage is a relative measurement uncertainty and refers to a percentage contribution in the value of the measurand. The current limits of the measurement ranges and the corresponding CMC uncertainty values, which change with the activity of the radioactive sources used, are available on request from the accredited body.
