Abstract: A radiation detector is disclosed for X- or gamma rays. In at least one embodiment, the radiation detector includes an array of scintillation detectors and a reflector layer separating these from one another. The reflector layer includes a binder matrix and particles of a light-reflecting material embedded therein, the surfaces of the particles being coated at least partially with a dispersant.

Abstract: A radiation detector for X-rays or gamma rays is disclosed. In at least one embodiment, the radiation detector includes an array of scintillation detectors and a reflector layer that separates the latter from one another and is formed essentially by a binding agent matrix and particles, incorporated therein, of a light-reflecting material. Further, the reflector layer is interspersed with microcavities.

Abstract: A radiation detector is disclosed for X radiation. In at least one embodiment, the detector includes a detector array that has a multiplicity of scintillators separated from one another by partition walls, and a photodiode array that is arranged on the side of said detector array averted from the radiation. In at least one embodiment, electronic subassemblies are arranged in an insensitive region of the photodiodes that is covered by the partition walls, and the partition walls include a material that has an X-ray absorptivity of more than 50%.
