Abstract
An apparatus and method for detecting radiation, which can improve the resolution of a radiation image and contribute to the simplification of the manufacture of the apparatus, are provided. The apparatus includes an upper electrode layer transmitting radiation; a first photoconductive layer becoming photoconductive upon exposure to the radiation and thus generating charges therein; a charge trapping layer trapping therein the charges generated in the first photoconductive layer and serving as a floating electrode; a second photoconductive layer becoming photoconductive upon exposure to rear light for reading out a radiation image; a lower transparent electrode layer charged with the charges trapped in the charge trapping layer; a rear light emission unit applying the rear light to the second photoconductive layer via the lower transparent electrode layer in units of pixels; and a data processing unit reading out a signal corresponding to the charges trapped in the charge trapping layer from the lower transparent electrode layer and generating a radiation image based on the read-out signal.
