Definition & Explanation
Depth cargo scanning security systems are non-intrusive inspection technologies that use penetrating radiation – typically X-rays, gamma rays, or computed tomography – to image the interior of containers, vehicles, and consignments without physically opening them. Customs and border agencies deploy them to detect contraband, weapons, explosives, and radioactive materials that would escape visual inspection. Modern installations produce high-resolution cross-sectional images, analysed by trained operators or AI-assisted software. Widely used at seaports, land border crossings, and air cargo facilities, they enable risk-based screening with minimal disruption to cargo flow. Unlike baggage X-ray units, freight scanners are engineered for full-size shipping containers and loaded heavy goods vehicles.
