Abstract:
1. A radiation image detector comprising: a radiation image recording medium having a set of layers layered in the order of a first electrode layer which is transparent to radiation carrying a radiation image, a photoconductive layer that generates electric charges when exposed to the radiation transmitted through said first electrode layer, a storage section that stores said charges generated in said photoconductive layer, and a second electrode layer having a first striped electrode composed of a plurality of first wire electrodes disposed in parallel at predetermined intervals, and a second striped electrode composed of a plurality of second wire electrodes disposed between said first wire electrodes; a first detecting section connected to said first striped electrode and detects said charges stored in said storage section using said first and second striped electrodes; and a second detecting section, which is connected to said second striped electrode, that detects the current flowing through said second striped electrode in accordance with the amount of said charges being generated in said photoconductive layer while the radiation image detector is being irradiated with radiation.
