| Zusammenfassung | The quantity to be measured in dosimetry for radiation therapy is the absorbed dose to water, Dw. At the Physikalisch-Technische Bundesanstalt a water calorimeter is established as the primary standard for Dw in 60Co radiation under reference conditions. The water calorimeter is capable of measuring the absorbed dose to water with a combined standard uncertainty of 0.20%. Some aspects of the design and operation of the water calorimeter are discussed. Detailed experimental and theoretical investigations for the different influence quantities affecting the calorimetric results are presented. |
