MEASURAND        Activity concentration of a solution

NOMINAL VALUE      100 kBq/g

 

The key comparison reference value xR and its associated standard uncertainty uR are computed from a power moderated mean of the reported results, see CCRI(II)-K2.Fe-55 Final Report where

 

        xR = 101.49 kBq/g         uR = 0.23 kBq/g

 

The degree of equivalence of laboratory i relative to the key comparison reference value xR is given by a pair of terms, both expressed in kBq/g.
