It is possible to reliably avoid a problem that radiation irradiation does not stop even when an accumulated radiation dose reaches a target radiation dose. An AEC unit starts monitoring an integrated value of a radiation dose detection signal from a detection pixel and an output of an irradiation continuation signal at the same time, and continuously transmits the irradiation continuation signal in a predetermined period while the integrated value does not reach a threshold value. When the integrated value reaches the threshold value, the output of the irradiation continuation signal is stopped. The irradiation continuation signal is transmitted to an irradiation signal I/F of a radiation source control device through an irradiation signal I/F by wireless. The radiation source control device stops X-ray irradiation by an X-ray source when the irradiation signal I/F does not receive the irradiation continuation signal.
