Results: Reference and measured dose-rate values for applicator CCA are shown in Fig 2, with C G ranging from 1.16 to 1.08, more correction needed near the applicator surface. The C G factor variation is the largest for applicator CCX because of applicator’s smallest size and curvature. For three applicators CCX, CCA and CCB the measured dose rates were 6 % smaller on average than reference values.
