Abstract
A radiation detector is constituted by: a recording photoconductive layer; and electrodes provided on both sides of the photoconductive layer. Electric charges, which are generated within the recording photoconductive layer when radiation is irradiated thereon while a predetermined biasing voltage is being applied between the electrodes, are read out as electric signals. The recording photoconductive layer is formed by amorphous selenium that contains alkali metal elements within a range from 0.0007 atomic ppm to 0.0035 atomic ppm.
