The increasing use of brachytherapy sources has highlighted the need to confirm the traceability to national standards of air kerma rate measurements made by suppliers and to provide a simple means for the user to check the activity of such sources. A programme of work, initiated under the EUROMET framework, has confirmed the traceability to NPL of air kerma rate measurements made by Amersham International plc for wire sources of 192Ir. In addition, intercomparison exercises are under way between national laboratories. The wires used in this work have provided the means to calibrate the NPL secondary standard radionuclide calibrator both in terms of air kerma rate and of activity, thus providing the hospital user with the basis of a simple and accurate quality control system for these particular types of wire.
