Abstract
A radiation imaging apparatus comprises an imaging unit including an effective region including pixels for generating a radiation image based on irradiated radiation and a receptor field region including pixels for measuring a dose of the radiation, and a control unit configured to output a signal for controlling irradiation of the radiation by comparing the measured dose with a threshold. An effective region index representing the effective region and a receptor field index representing the receptor field region are identifiably formed on a radiation incident surface of the imaging unit.
