Abstract: A scintillation detector for measuring radioactive particle radiation includes at least one planar detector element made from a scintillator material. Each detector element is provided with a light guide which is placed on at least one planar side of the element, the light guide having two ends that are guided into an evaluation unit and which is configured as a wavelength shifting fibre. The evaluation unit includes one or more photomultipliers and a logic unit to which the signals of the photomultiplier(s) are applied. The two ends of the light guide are respectively connected to a separate photomultiplier or a channel of a photomultiplier and the outputs of the photomultiplier(s) are connected to the logic unit which produces an output signal for a detector element when the signals are substantially simultaneously applied to the ends of the light guide of a detector.
