The increasing use of positron emission tomography for medical imaging and the availability of short-lived positron emitters has raised concerns about the accuracy of calibration of secondary standard measurement systems and the viability of using a single long-lived positron emitter as a reference calibration source for all positron emitters ...

As part of a BIPM key-comparison of (85)Kr, a primary standardisation using internal gas proportional counting was performed. The supplied activity for the comparison was approximately 40 MBq and a two-stage dilution was required to reduce the activity concentration to a level suitable for gas counting.
