Abstract

Within the framework of the JRP06 European project Increasing Cancer Treatment Efficacy Using 3D Brachytherapy, a prototype of a graphite standard calorimeter for the measurement of the absorbed dose rate to water, D w, for 192Ir sources used in high dose rate (HDR) brachytherapy has been developed at the Italian National Institute of Ionizing Radiation Metrology (ENEA-INMRI). The calorimeter was tested at the SantAndrea Hospital in Rome, where D w measurements were performed in the quasi-adiabatic mode of operation using an 192Ir MicroSelectron® HDR V2 source. The D w measurements showed a reproducibility of about 1%, while the combined standard uncertainty on the D w value at the distance of 1 cm from the source was estimated as 1.4%, lower than the uncertainty of D w determined from the reference air-kerma rate. © 2012 BIPM & IOP Publishing Ltd.
