MEASURAND Equivalent activity of F-18
The key comparison reference value xR for this radionuclide is estimated to be
xR = 15 293 kBq with a standard uncertainty uR = 19 kBq
(see Section 7 of the BIPM.RI(I)-K4.F-18 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.
