AS&E X-ray inspection systems are used by governments and corporations around the world to combat terrorism, drug and weapons smuggling, illegal immigration, and trade fraud. AS&E specializes in detection technologies that can uncover dangerous and elusive threats, including explosives, plastic and metal weapons, and radioactive devices, such as dirty bombs and nuclear WMD. AS&E systems also detect commonly smuggled goods, such as drugs and alcohol. These X-ray systems are deployed worldwide at ports and borders, and military and high-threat facilities.

AS&E's signature technology - Z(R) Backscatter - offers unparalleled detection capabilities, making it the technology of choice when the highest levels of security are required.

AS&E's line of Mail, Parcel and Baggage (ParcelSearch(TM)) systems offers varying tunnel sizes and configurations to fit your specific application and inspection environment. Compact X-ray units screen smaller items, including mail and briefcases; while larger, open-tunnel systems inspect oversized baggage and small cargo.

AS&E systems for Cargo and Vehicles (CargoSearch(TM)) - available in mobile, relocatable, and fixed-site configurations - can be customized to meet specific inspection requirements and integrated into existing security operations. CargoSearch systems are ideal for inspecting cars, vans and trucks, as well as palletized cargo, and air and sea cargo containers. AS&E's Radioactive Threat Detection (RTD) technology is an option for some of these systems.
