Abstract: Technetium-99m was standardised by the 4π(LS)ce-γ coincidence extrapolation method. Sensitivity of the 4π(LS) channel to two types of radiation, namely conversion electrons and γ-rays, resulted in incorrect activity values being obtained when this was not adequately accounted for. Measurements were more robust when the LS detection efficiency was optimised, and when a γ-window setting was used that monitored the combined LS efficiency for conversion electrons and γ-rays. The primary standard was internationally compared through participation in the BIPM.RI(II)-K4.Tc99m key comparison.

Abstract: In 2017, comparisons of activity measurements of 18 F, 64 Cu, 99m Tc and 11 C using the Transfer Instrument of the International Reference System (SIRTI) took place at the Australian Nuclear Science and Technology Organisation (ANSTO, Australia). Ampoules containing 18 F, 64 Cu and 99m Tc solutions were measured in the SIRTI for about 1.7 to 4 half-lives. The ANSTO carried out the primary standardization of the activity in the oules by 4π(LS)β—γ coincidence measurements. The comparisons, identifiers BIPM.RI(II)-K4.F-18, BIPM.RI(II)-K4.Cu-64 and BIPM.RI(II)-K4.Tc-99m are linked to the corresponding BIPM.RI(II)-K1.F-18, BIPM.RI(II)-K1.Cu-64 and BIPM.RI(II)-K1.Tc-99m comparisons. The BIPM.RI(II)-K1 18 F and 99m Tc key comparison reference values have been updated to include the latest BIPM.RI(II)-K4 linked results and degrees of equivalence for those three comparisons have been evaluated.
