Abstract: A control unit of an electronic cassette switches the power supply state of a plurality of blocks BL which share a signal processing of a signal processing circuit between an operating state and a non-operating state. The control unit switches the block BL from the non-operating state to the operating state before a predetermined time TW necessary for stable operation of the block BL from a timing when the reading of charge starts in the block BL.

Abstract: In a case in which an imaging mode continuously acquiring a plurality of energy subtraction images is performed, a radiation source control unit of a control device performs radiation source control for performing a one-shot imaging operation, in which only one of first radiation and second radiation is emitted, at least once for one two-shot imaging operation in which the first radiation and the second radiation are continuously emitted. In a case in which the imaging mode is performed, a detector control unit performs detector control to direct a radiation detector to output a first radiographic image based on the first radiation and a second radiographic image based on the second radiation.

The radiation detection system includes a radiation output device having an output control unit, and a radiation detection device having a recognition unit that recognizes whether radiation has been output from the radiation output device on the basis of a radiation detection signal. The output control unit causes radiation to be output at a first intensity from a time point of the start of outputting of radiation, and then causes the radiation to be output at a second intensity. The first intensity is an intensity higher than the second intensity and satisfying a threshold value condition set in advance in the recognition unit. The recognition unit recognizes that a detection signal of the radiation with the first intensity satisfies the threshold value condition, thereby recognizing the start of outputting of the radiation.
