Abstract

Concerns have been raised within the nuclear medicine field about the accuracy of measurements of the activity of 89Sr. Measurements of 89Sr activity at NPL have found that the 85Sr impurity, that is present in the 89Sr solution, has a significant effect on the response of radionuclide calibrators routinely used in UK hospitals.
To assess the magnitude of these effects on the accuracy of clinical measurements of the activity of 89Sr, a comparison was conducted between the National Physical Laboratory (NPL) and the UK hospital physics community.
93 results were reported for this comparison. Only 58 % of these results were within 5 % of the NPL value. There were also a small number of results reported with large discrepancies (up to 82 % in error). All results are for 10 R Schott vials only.
This comparison has revealed that there is still room for improvement in measuring this radionuclide and, to this end, NPL has derived correction factors for the NPL secondary standard radionuclide calibrator and Capintec systems.
