| Zusammenfassung | A large air-filled parallel-plate extrapolation chamber (GROVEX) with thin graphite front and back electrodes is used as a primary standard measuring device for low-energy photon brachytherapy sources from which the unit of air kerma strength or reference air kerma can be derived. The setup of the extrapolation chamber is described together with the method of evaluation of the extrapolation curves. Initial air kerma rate measurements with this chamber of previously NIST calibrated 125I seeds are presented. |
