Short-lived radionuclide F-18 - BIPM
The most recent results of BIPM.RI(II)-K4.F-18 have been published in the KCDB, now including results obtained by ANSTO (Australia). This is a continuous comparison of radioactivity using a transfer instrument for the International Reference System (SIR), in which 11 institutes presently have valid linked data from participation. F-18 has a very short half-life of less than 2 h where the use of a transfer instrument is of particular interest. F-18 is notably used in medical diagnostics.
