Abstract
A radiation detector, which can reduce power consumption of a read-out module, comprises: a radiation detection unit which includes a plurality of pixels connected to a plurality of gate lines and a plurality of data lines that intersect and arranged in a matrix form, and which store, in the plurality of pixels, charges generated in proportion to radiation dosage; a gate module for selecting at least one of the plurality of gate lines and controlling the selected gate line; the read-out module for selecting at least one of the plurality of data lines, and reading charges stored in at least one exposure detection pixel determined by the selected data line and the selected gate line; and an automatic exposure detection unit for determining whether the radiation detection unit is exposed to radiation by using a charge quantity read by the read-out module from the exposure detection pixel in every preset period.
