| Zusammenfassung | After the implementation of a water calorimeter as a primary standard for absorbed dose to water, DW, in Co-60 radiation, efforts are being made at PTB to extend the application possibilities of water calorimetry for radiotherapy dosimetry in various irradiation conditions and in various radiotherapy beams. In addition to the determination of DW in high-energy photon- and electron radiation, this covers also the application in 70 kV, 100 kV and 150 kV medium energy x-rays, in a scanned 280 MeV carbon ion beam and in close proximity to a 350 GBq Ir-192-brachytherapy source, respectively. For the latter-mentioned applications, first experiments performed with different water calorimeters are presented and emphasis is placed on discussing the heat conduction effects occurring during the different measurements.
