Claim:
1. A radiation imaging apparatus comprising: an imaging pixel configured to acquire a radiation image, wherein the imaging pixel includes an imaging switching element for outputting a signal from an imaging conversion element; a detection pixel configured to detect radiation incidence, wherein the detection pixel includes a detection switching element for outputting a signal from a detection conversion element; a first control line electrically connected to a control electrode of the imaging switching element; a second control line electrically connected to a control electrode of the detection switching element; a signal line electrically connected to a main electrode of the detection switching element; a capacitance line arranged to be capacitively coupled with the signal line, wherein the capacitance line is different from the first control line and the second control line; a driving unit electrically connected to the second control line and the capacitance line and configured to apply a voltage to the detection switching element and the capacitance line; and a control unit configured to control the driving unit to apply, in a case where an on-state or off-state voltage is applied to the detection switching element, a voltage having an opposite polarity to that of the on-state or off-state voltage to the capacitance line.
