A radiation imaging system comprises a sensor unit of a radiation imaging device, detecting an incident radiation R irradiated from a radiation generator; an arithmetic unit calculating an accumulated dose of the radiation detected by the sensor unit; and an imaging control unit outputting an irradiation stop signal for stopping the irradiation of the radiation R to the radiation generator when the accumulated dose reaches a threshold or more, wherein the imaging control unit sets the threshold based on a dose rate of the radiation R determined based on a relationship between the accumulated dose and a time, and a delay time from a time of outputting the irradiation stop signal to a time of stopping the irradiation of the radiation of the radiation generator.

A radiation device is wirelessly connected to a radiography device that generates dynamic image data and which controls sequential radiation. The radiation device includes a signal generator and a first determiner. The signal generator generates (i) first pulse signals emitted by the radiography device, (ii) second pulse signals synchronized with a first count value obtained by counting up the first pulse signals, and (iii) a second count value obtained by counting up the second pulse signals. The first determiner determines whether to start radiation based on a delay time which is a difference between a first time point count value and a second time point count value. The first time point count value indicates a time point at which a radiation permission signal is transmitted. The second time point count value indicates a time point at which the radiation permission signal is received.
