12. A radiation imaging apparatus comprising:
a detection unit configured to detect radiation applied by a radiation generating apparatus;
a plurality of memories storing programs; and
at least one processor that executes the stored programs, which cause the at least one processor to:
perform an automatic exposure control to determine whether to stop an application of radiation based on an accumulated dose of the detected radiation and to notify the radiation generating apparatus of an instruction to stop the application of radiation in a case where it is determined to stop the application of radiation; and
store, in a first memory among the plurality of memories, data to be used when the at least one processor makes a determination whether to stop the application of radiation,
wherein the at least one processor stores, in the first memory, in a second memory different from the first memory among the plurality of memories, or in both the first memory and the second memory, data not to be used when the at least one processor makes the determination whether to stop the application of radiation.
