<p>PROBLEM TO BE SOLVED: To provide an inspecting method for a radiation image photographing device which can easily detect abnormality of a light convergence unit of the radiation image photographing device and an abnormality notification system for the radiation image photographing device which can speedily report the detected abnormality. SOLUTION: The irradiating light of a blue LED 10bk can be transmitted through a cut filter l0bj and the possibility that blue LEDs 10bk become abnormal at the same time is low, so the abnormality of the light convergence unit (the exiting light cut filter 10bj, an acryl aggregation, and a photomultiplier 10bd) can be detected by using an output signal value of relatively high reliability obtained by reading test light emitted by the blue LED 10bk. Further, a sign of abnormality occurrence can be read by periodically performing inspection, the abnormality occurrence of the radiation image photographing device can be predicted, and countermeasures can be taken.</p> |
