to the present invention is produced it should be noted that the figure depicts only a small part of a complete radiation detector which typically comprises a much larger number of detector cells fig1 a shows the first step of the procedure in which two scintillator elements 110 110 u2032 as well as an associated pda 120 are provided the two scintillator elements 110 110 u2032 are disposed adjacent to each other lined up in z direction which is the direction of radiation incidence during the later operation of the radiation detector the scintillator elements are typically cuboid blocks of a material like gos csi znse or cwo that generate secondary photons from incident high energy primary photons the two scintillator elements are preferably separated from each other by a reflective layer 111 to prevent cross talk effects the pda 120 typically consists of a plate of a semiconductor material for example of silicon with in this example two photodiodes 122 formed on its surface by appropriate doping in the regions facing the scintillator elements furthermore electrical leads 123 are provided on said surface of the pda 120 which are connected to the aforementioned photodiodes 122 and which extend into a lower part 121 of the pda additional wires 131 have.
