Scope

This verification system table is suitable for verifying high-precision activity and photon emission rate measuring instruments in the range of 1×102 to 4×106 s-1. It specifies the use of the national reference for activity units (Bq). With the help of working references, the procedure for transferring the unit values of activity and photon emission rate to working measuring instruments is provided, and the uncertainty and verification methods are specified.
