摘要： A detector for high energy radiation such as X-ray radiation or gamma radiation comprises a layer (1) of scintillator material, an intermediate Mylar layer (2) and a solid state detector array (3) located behind them. The intermediate layer has an atomic number which is less than that of the scintillator material or the radiation sensitive regions of the detector. Hence, secondary electrons produced at the detector region move to the intermediate layer, reducing the dose delivered by X-rays to the sensitive regions and prolonging the life of the detector.
