Abstract

PURPOSE:To reduce the energy dependence of detection efficiency, by providing parts different in emission quantity corresponding to the energy of radiation or combining a scintillator of a separate body with a radiation detector detecting light and radiation. CONSTITUTION:Two scintillators a4, b5 different in energy dependence are bonded to the N-layer 2 of a semiconductor radiation detector and covered with reflecting films 6. Further, the whole of the N-layer 2 and the scintillators 4, 5 are covered with a light blocking film. The peak set to a peak discriminator is appropriately set corresponding to an energy band to be measured. Further, the scintillators are brought to one and films partially different in transmissivity or irises partially changed in the quantity and size of a hole may be provided between the N-layer and the scintillator. By this method, detection can be performed in the energy band being an object to be detected with uniform detection efficiency.
