1. A radiation imaging apparatus comprising:
a sensor configured to detect radiation from a radiation generation apparatus;
a processor; and
a memory storing a program which, when executed by the processor causes the radiation imaging apparatus to:
transmit a signal for stopping irradiation of radiation to the radiation generation apparatus using a cumulative dose of the radiation detected by the sensor, an irradiation time for the radiation, an irradiation start threshold, and an irradiation stop threshold,
wherein, after the cumulative dose reaches the irradiation start threshold which can be changed by an operator's operation, the signal for stopping irradiation of radiation is transmitted to the radiation generation apparatus based on the irradiation stop threshold obtained by using the irradiation time and the irradiation start threshold.
