Abstract

Detection apparatus for detecting radiation The invention relates to a detection apparatus for detecting radiation. The detection apparatus comprises at least two scintillators (14, 15) having different temporal behaviors, each generating scintillation light upon reception of radiation, wherein the generated scintillation light is commonly detected by a scintillation light detection unit (16), thereby generating a common light detection signal. A detection values determining unit determines first detection values by applying a first determination process and second detection values by applying a second determination process, which is different to the first determination process, on the detection signal. The first determination process includes frequency filtering the detection signal. Since the scintillation light of the different scintilla-tors is collectively detected by the same scintillation light detection unit, detection arrangements with, for example, side-looking photodiodes for separately detecting the different scintillation light of the different scintillators are not necessarily required, thereby reducing the technical complexity of the detection apparatus.
