| 1. A radiation imaging apparatus comprising:
a conversion circuit unit in which a plurality of pixels including conversion elements are arranged into an array on a substrate;
a reading circuit unit that reads signals from said conversion circuit unit;
a controller for controlling said radiation apparatus to take a radiation image in a radiographic operation period, the radiographic
operation period comprising an idling operation period alternately including a wait period and a non-read period prior to
emission of radiation and a reading operation period subsequent to emission of radiation; and
a radiation-induced signal generating unit to generate a radiation-induced signal to a radiographer during the idling operation
period except for the non-read period for synchronizing the operation of said radiation imaging apparatus with the emission
of radiation.
