Abstract: A gamma radiation detector, wherein it comprises a xenon crystal, a xenon atmosphere above said xenon crystal, a pair of electrodes comprising two metallic electrodes on either side of the xenon crystal, the first electrode being brought to negative potential (cathode) and located in the vicinity of one face of the xenon crystal and the second electrode brought to positive potential (anode) is placed parallel to the cathode in the xenon atmosphere and visualization device of the photons emitted in the gaseous xenon, whereby the face of the xenon crystal in the vicinity of the cathode is arranged in such a way that it receives the gamma radiation to be measured.

Abstract: The camera comprises an emitting section and a receiving section which are both located on the surface of a portion of a cylinder. The receiving section consists of juxtaposed and parallel strips located in the central part of the portion of cylinder. The emitting section consists of two groups each constituted by a band of parallel strips which is placed on each side of the receiving section. Each emitter is constituted by a pair of strips having parallel sides each forming part of a directrix of the cylinder. Electronic means are provided for exciting the different emitting strips and collecting the signals received by the different receiving strips.
