Security inspection apparatus designed for the safe, efficient and rapid inspection of products to detect the presence of objectionable X-ray detectable items. The apparatus comprises a source of continuous X-rays of sufficiently low intensity that conventional photographic film is insensitive thereto, a fluoroscopic screen, a television camera adapted to transmit electrical impulses which provide a visual picture of the images on the fluoroscopic screen to a television monitor and means for intensifying the electrical impulses transmitted by the camera so that the image on the monitor is clearly visible. The apparatus also comprises means for continuously moving products such as baggage between the X-ray source and the screen at a uniform speed within a shielded compartment so that a continuously changing visual picture of the contents of the baggage is displayed on the monitor, providing a three-dimensional picture of each detectable item in the baggage and an indication of its relative location therein.
