BIPM.RI(II)-K1.Ag-110m
MEASURAND SIR equivalent activity of Ag-110m
The key comparison reference value xR for 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) /xR and its expanded uncertainty Ui at a 95 % level of confidence, both expressed in kBq/MBq.
