BIPM.RI(II)-K1.Ag-110m

 

MEASURAND    SIR equivalent activity of Ag-110m

 

The key comparison reference value xfor this radionuclide is estimated to be

 

xR = 5980.8 kBq with a standard uncertainty, uR = 6.4 kBq                  (see Section 4.1 of the Final Report).

 

Degrees of equivalence represented by Di = (xI - xR) and its expanded uncertainty Ui at a 95 % level of confidence are both expressed in kBq, where xi is the equivalent activity for laboratory i.

The Degrees of equivalence are also given in relative terms by Di = (xI - xR) /xand its expanded uncertainty Ui at a 95 % level of confidence, both expressed in kBq/MBq.
