BIPM.RI(II)-K1.Ba-133 and APMP.RI(II)-K2.Ba-133
MEASURAND SIR equivalent activity of Ba-133
The key comparison reference value xR for this radionuclide is estimated to be
xR = 43 899 kBq with a standard uncertainty uR = 59 kBq
Degrees of equivalence represented by Di = (xI - xR) and its expanded uncertainty Ui at a 95 % level of confidence are both expressed in MBq, 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.
