1. A radiation imaging system comprising:
a radiation imaging apparatus configured to detect radiation emitted from a radiation source; and
a radiation control apparatus configured to control the radiation source, wherein
the radiation imaging apparatus is configured to output dose information, which includes a dose of radiation entering the radiation imaging apparatus and a time at which the dose was detected, to the radiation control apparatus a plurality of times, and
the radiation control apparatus is configured to
set a threshold dose based on a difference between a time included in the dose information from the radiation imaging apparatus and a time at which the radiation control apparatus received the dose information, and
control the radiation source to stop radiation irradiation based on the threshold dose.
