Pretty sure he was just linking for the picture on that page which is a full vehicle x-ray produced from a system like https://www.smithsdetection.com/products/hcvg/ https://www.smithsdetection.com/products/hcvg/ > The system’s high-performance imaging capability provides the operator with detailed radioscopic images of container or vehicle and its contents, with organic and inorganic material discrimination and colourisation based on atomic number, allowing for rapid and reliable results in a single scan. It colorizes the x-ray based on the atomic composition of the materials so this system could probably detect a bunch of solid gold parts.
