Development of a Traceable Calibration Methodology for Solid⁶⁸Ge/⁶⁸Ga Sources Used as a Calibration Surrogate for¹⁸F in Radionuclide Activity Calibrators

Abstract

The ability for NIST to calibrate these epoxy-based mock syringes enabled, for the first time to our knowledge, the direct traceability to the national (68)Ge standard to be established for this type of source. Through a direct comparison with the NIST (18)F standard, the determination of the relative response ratios in activity calibrators enabled the equivalent (18)F activity to be determined in a way that was also traceable to the national (18)F activity standard.
