Abstract
A solution of 59Fe was standardized in the frame of a Bureau International des Poids et Mesures (BIPM) international key-comparison piloted by Asian Pacific Metrology Program (APMP) regional metrology organization. The method used was the live-timed 4πβ-γ anticoincidence counting with extended dead-time with efficiency extrapolation method. The confirmation of these results was performed by conventional 4πβ-γ coincidence counting with efficiency extrapolation and CIEMAT/NIST liquid scintillation counting methods. The value of the evaluated anticoincidence measurement was used to calibrate the LNMRI second standard ionization chambers for providing 59Fe solutions to nuclear medicine canters in the procedures of anaemia diagnosis. Besides this value was adopted as the comparison value of LNMRI and sent to APMP organization. The half-life of 59Fe was determined following the decay of one ampoule sample with 59Fe solution in an ionization chamber (Centronic model IG12).
