Radiation detector

Abstract

Abstract PURPOSE:To achieve transmission of light generated from the interaction with radiation at a high efficiency to a light detector with a higher light emission efficiency by arranging a scintilator to act not only as a light emitting section but also serve as a light waveguide path. CONSTITUTION:An internal light reflecting thin film (covered layer) 5 is formed with a circumferential surface of a plastic scintilator 4 shaped in a fiber by evaporation so that the plastic scintilator 4 acts as light waveguide path. A scintilator fiber thus arranged in housed in cases 6 arrayed two dimensionally. Light transmitting through the scintilator 4 is detected with a light detector 3 and the detection signal is fed to a data processing section. With such an arrangement, internal light reflection by the internal light reflecting thin film 5 eliminate the cross talk of light. In addition, the scintilator 4 itself acts as light waveguide path thereby permitting a larger effective sectional area of thereof with respect to incident X rays.
