Intercomparison of radionuclide calibrator measurements in U.K. hospitals.

The Life Sciences Working Group of the International Committee for Radionuclide Metrology had received various reports of users of radionuclide calibrators experiencing problems in obtaining accurate measurements of radionuclide activity. Working Group members were encouraged to initiate surveys in their own countries to assess the magnitude of these problems. The results of the survey in the United Kingdom are given.
