Zusammenfassung:	A water phantom is described, having a detector that is positionable in a container filled with water for measuring an ionizing radiation. The water phantom has at least one sensor for ascertaining an orientation of a positioning device, relative to a water surface, so that errors in measurement caused by inaccuracy of positioning detector relative to the water surface can be avoided with low time cost. The orientation determination is based either directly on distances relative to the water surface that are measured by at least two spacing sensors or, indirectly on inclinations, each measured by at least one gravity-sensitive inclination sensor.
