Abstract
A new 18F primary standardization carried out at ENEA-INMRI by three different absolute techniques, i.e. 4ÏγNaI(Tl)γ high-efficiency counting, TDCR and 4Ïβ(LS)-γ[NaI(Tl)] coincidence counting method, allowed the calibration of a fixed well-reentrant IG11 ionization chamber (IC), with an uncertainty lower than 1%, and to check the calibration factor of a portable well-type IC NPL-CRC model, previously calibrated. By the new standard the ENEA-INMRI was linked to the BIPM International Reference System (SIR) through the BIPM SIR Transfer Instrument (SIRTI).
