Abstract
Provided is a radiation imaging apparatus, including: a first conversion element arranged to convert a radiation ray into electric charge in order to obtain a radiographic image; a first amplifier arranged to output a voltage corresponding to the electric charge of the first conversion element; a second conversion element arranged to convert the radiation ray into electric charge in order to detect radiation irradiation; a second amplifier arranged to output a voltage corresponding to the electric charge of the second conversion element; and a control circuit configured to control the first amplifier and the second amplifier, in which the control circuit is capable of controlling the second amplifier independently of control that is exerted over the first amplifier.
