Abstract
The present invention provides radiation detector, radiographic imaging device and radiographic imaging system that may detect irradiated radiation while maintaining quality of radiographic image. The radiation detector has: pixels having a sensor portion that generates charges in accordance with light converted from irradiated radiation, TFT switch that outputs, to a signal line, charges read-out from the sensor portion, and radiation detection TFT switch that is not connected to a signal line; and radiation detection pixels that have the sensor portion, the TFT switch, and radiation detection TFT switch that is connected to a signal line and that outputs, to the signal line, charges read-out from the sensor portion. The radiation detection TFT switches are connected to radiation detection scan lines, and ON/OFF states are controlled by scan signals that are outputted from a radiation detection control circuit.
