Abstract:
    The present inventive radiation image detector improves the travel characteristic of electrons by preventing crystallization at the interface between a photoconductive layer and a lower layer and at the interface between the photoconductive layer and an upper layer, prevent an increase in image defects due to time passage. The present inventive radiation image detector is in a radiation image detector superposed one on another in the order of a first electrode (1) for transmitting an electromagnetic wave for recording that carries a radiation image; a photoconductive layer (3) for recording generates charges by irradiation with the electromagnetic wave for said recording by permeating a first electrode (1) and has amorphous selenium as its major component and further contains alkali metal; the plurality of charge-collecting electrodes (4) and the substrate (5). Further, an amorphous selenium layer is provided as an anti-crystallization layer (2) between the first electrode (1) and the photoconductive layer (3) for recording. The amorphous selenium layer contains at least one element selected from the group consisting of As, Sb and Bi at 5% to 40%.
