Non-intrusive Inspection

Non-intrusive Inspection (NII) refers to techniques used to examine objects, cargo, or vehicles for security or safety purposes without opening or altering them. These methods include advanced imaging technologies like X-ray or gamma-ray scanners, which create detailed images to detect hidden contraband, explosives, or dangerous materials. NII allows authorities to inspect quickly and safely, minimizing disruption while maintaining security. It is widely used at airports, ports, and border crossings to efficiently screen large volumes of items without intrusive searches.
