Abstract

Device for position determined detection of radioactive radiation, comprising at least one pair of layers (1, 2), one of the layers in the pair here being called the primary layer (1) and the other the secondary layer (2), the layers comprising scintillating elements (3, 4) of some length called primary elements (3) in the primary layer (1) and secondary elements (4) in the secondary layer (2), the two layers (1, 2) being positioned on each other that the direction of the primary elements (3) in the primary layer (1) cross the direction of the secondary elements (4) in the secondary layer (2), the elements (3, 4) being connected to light sensitive means (21, 23, 25, 27, 39), which are arranged to react on light pulses that are generated in the scintillating elements (3, 4) by the radioactive radiation, and the light sensitive means are connected to a logic circuit system (38) for determining of where light pulses have been generated I the detection device. According to the invention a heavy material is arranged in or in the vicinity of the scintillating elements (3, 4), and/or the scintillating elements (3, 4) in the layers (1, 2) are connected to the light sensitive means (21, 23, 25, 27, 39) according to a multiplexing schedule, which will decrease the number of necessary light sensitive means (21, 23, 25, 27, 39).
