This poster briefly presents the results from a comparison exercise involving Y-90 performed in October 2009 to assess the measurement capability of Medical Physics Departments in the UK and Ireland.

The report shows discrepancies of up to 20 % from the NPL certificated value and highlights issues with measuring 90Y in different geometries. Further details and a full version of the report can be downloaded from the NPL website.
