Title: Radiation image pickup device and radiation image pickup system

Abstract: A large-area and compact radiation image pickup device is provided in whichan imaging optical system is arranged between a solid image pickup elementand a wavelength converting member, and a radiation such as x-rays asconverted into the sensitive wavelength region of the solid image pickupelement by the wavelength converting member is guided by the imagingoptical systems to convert the radiation into an electric signal by aplurality of photosensors. The radiation that has passed through thewavelength converting member is absorbed by a light transmissive member ora unity magnification erectly imaging optical system, thereby reducing orpreventing irradiation of the photosensors or the like with the radiation.
