ABSTRACT:
A light transmitting member is disposed between a scintillator element array consisting of a plurality of scintillator elements and a multichannel photodiode including a plurality of photodiode elements. Light transmitting elements of the light transmitting member are formed of a material whose light transmission factor is higher than that of the scintillator elements and which absorbs radiation (X-rays). Absorbed by the scintillator elements and the light transmitting elements, therefore, incident X-rays are prevented from being projected on the photodiode. On the other hand, light emitted from the scintillator elements is transmitted through the light transmitting member with high light transmission factor, and detected by the photodiode. Thus, the detectable quantity of light is large.
