Abstract: The paper presents some recent results of the Radionuclide Metrology Laboratory (RML) from IFIN-HH, concerning the assurance of the international traceability for the measurement of (131)I solution aimed to continue the national chain for nuclear medicine applications in Romania. The following sequences of the traceability are presented: the absolute standardization of solution by the 4pibeta-gamma coincidence, efficiency extrapolation method and participation in the BIPM.RI(II)-K1.I-131 key comparison; and recalibration of the CENTRONIC IG12/20A ionization chamber secondary standard. The participation in the IAEA/SSDL (SSRL) (131)I comparison is also presented.
