放射線透視検査装置。、A fluoroscopic image of the object placed within the field of view of the radiation generator is converted into a visible image by the visible image converter, and this visible image is captured by a television camera and displayed on a monitor to detect defects in the object. In a radiographic inspection apparatus for inspecting a radiographic image, a normally closed shutter is movably arranged between the radiation generator and the visible image converting section and prevents direct irradiation of the visible image converting section with radiation; a position detector for detecting that the tip of the subject has reached a predetermined position within the field of view for radiation irradiation; A shutter drive circuit that opens the shutter, selects one scanning line of the television camera, detects the difference between the signal value and the peak value of the fluoroscopic image portion of the subject of the video signal, and when the difference is within a predetermined value, the A radiation fluoroscopic inspection apparatus comprising: a shutter control circuit that supplies a signal to the shutter drive circuit to stop the shutter from running. ,
