American Science and Engineering, Inc. (“AS&E”) (NASDAQ: ASEI), a leading worldwide supplier of innovative X-ray detection solutions, announces today it has secured a multi-million dollar order from Eastern Europe for the Company’s Sentry™ Portal cargo and vehicle screening system, Z Backscatter™ Van (ZBV), and multiple Gemini™ mail, parcel and baggage screening systems. “Using AS&E’s advanced X-ray technologies, security officials can detect a broad range of threats and contraband in a variety of settings and applications,” said Anthony Fabiano, AS&E’s President and CEO. “Working together, these systems provide security officials with an advanced level of security. For maximum flexibility, the ZBV ™ system can easily be deployed to find drugs, contraband, and explosives. The Sentry Portal drive-through system for cargo maintains the flow of traffic, while providing high-quality transmission images. Finally, for effective baggage screening, the Gemini system detects both organic materials such as explosives, and metallic threats with its unique combination of dual-energy and Z Backscatter technology — pioneered and perfected by AS&E.” About Sentry Portal System: High-Throughput, High-Penetration Drive-Through Cargo Inspection AS&E’s Sentry Portal system is an advanced, high-throughput, high-penetration, drive-through cargo inspection solution that delivers a reliable means of detecting threatening materials, weapons, and contraband hidden in cargo containers, tankers, and large vehicles while maintaining the flow of commerce. The system is extremely safe for drivers, operators and cargo, and offers the unique combination of high-throughput capability with unsurpassed image quality. Using a high-energy transmission X-ray source, the Sentry Portal provides high-penetration into inspected objects — up to 300 mm (12 inches) of steel — and unsurpassed image quality, with a throughput of up to 150 trucks per hour. Sentry Portal offers a means of scanning a very high percentage of containers at high volume seaports, border crossings, and security checkpoints. The system features a compact footprint allowing for installation in areas with space constraints. Safety Assured: Employing technology to avoid scanning the cab of the truck, a robust container locating sub-system ensures safe drive-through operation, so that the driver is never exposed to high-energy X-rays. About Gemini : Unique Multi-technology Parcel Inspection System The Gemini parcel inspection system is the lowest cost multi-technology parcel inspection system on the market and the only system to combine AS&E's Z Backscatter technology and dual-energy transmission. AS&E's Z Backscatter technology provides enhanced detection of organic materials such as explosives, drugs, and plastic weapons. Dual-energy transmission provides outstanding image quality, and enables the quick detection of a wide variety of threats such as guns, knives, and wires for improvised explosive devices (IEDs). In addition, dual-energy offers organic and metallic discrimination. Together, the Gemini system's two technologies provide the most information available about the contents of a parcel. The Gemini 6040, Gemini 7555, and Gemini 100100 systems offer multiple tunnel sizes to inspect air cargo, large packages, break-bulk cargo, mail and other small parcels to meet the security requirements for customs checkpoints, high-threat facilities, building lobbies, air-cargo facilities, and mailrooms. Z Backscatter Van (ZBV): Most Maneuverable, Versatile Mobile X-ray Detection System on the Market A breakthrough in X-ray detection technology, AS&E’s Z Backscatter Van is the number one selling non-intrusive mobile inspection system on the market. The ZBV system is a low-cost, highly mobile screening system built into a commercially available delivery van. The ZBV system allows for immediate deployment in response to security threats, and its high-throughput capability facilitates rapid inspections.
