<p>Provided is a radiological image pickup apparatus capable of obtaining more suitable radiological images by reducing the influence of noise generated at a current detecting means which detects current carried by applying radiation. The radiological image pickup apparatus (1) includes a plurality of radiation detection elements (7) two-dimensionally arranged in each region (r) defined by a scanning line (5) and a signal line (6), a switch means (8) the state of which is switched between on and off states depending on voltage applied to the connected scanning line (5), a scan drive means (15) having a gate driver (15b) that applies on voltage and off voltage to the switch means (8) through the scanning line (5) and a power supply circuit (15a) that supplies on voltage and off voltage to the gate driver (15b), a current detecting means (41) for detecting current carried between the power supply circuit (15a) and the gate driver (15b) or current carried through the scanning line (5), and a control means (23) for detecting at least the start of applying radiation on the basis of the value of the current detected by the current detecting means (41).</p> |
