Dosimetrie an HDR-Afterloading-Geräten mit Ir-192- und Co-60-Strahler: Vergleich verschiedener internationaler Dosimetrieprotokolle

We have shown that the standard deviations of the measured air kerma rate for the Co-60 source are generally larger than those of the Ir-192 source. The measurements with the well chamber had the lowest deviation from the certificate value. In all protocols and methods the deviations stood for both nuclides by a maximum of about 1.2% for Ir-192 and 2.5% for Co-60-sources respectively.
