U.S. Customs and Border Protection Places $9.1 Million Order for AS&E`s New MobileSearch HE Systems

CBP Orders First MobileSearch HE Systems for Port and Border Security
Applications
BILLERICA, Mass.--(Business Wire)--
American Science and Engineering, Inc. (AS&E®) (NASDAQ: ASEI), a leading
worldwide supplier of innovative X-ray detection solutions, announced today the
receipt of a $9.1 million order from U.S. Customs and Border Protection (CBP)
for multiple MobileSearch™ HE (High-Energy) cargo and vehicle inspection systems
equipped with both high-energy transmission and proprietary Z Backscatter™ X-ray
imaging for detecting threats and contraband including weapons, explosives,
drugs, and currency.

"We are pleased to provide CBP with AS&E`s MobileSearch HE systems to support
their counter-drug and anti-terrorism programs," said Anthony Fabiano, AS&E`s
President and CEO. "MobileSearch HE offers flexible and rapid response at
seaports, border crossings, and other high threat checkpoints. The system`s
combination of technologies offers the unique capability to simultaneously
detect both metallic and organic threats in cargo - providing detailed
information about the contents of the cargo."

This contract was funded by the Department of Homeland Security (DHS) American
Recovery and Reinvestment Act (ARRA) for Non-Intrusive Inspection (NII)
equipment - enhancing border security by expanding U.S. Customs and Border
Protection (CBP) capabilities to scan commercial traffic for contraband through
X-ray and other imaging technologies.

AS&E`s MobileSearch HE Cargo and Vehicle Inspection System:
High-Energy Inspection Plus Z Backscatter Imaging in Highly Mobile Configuration

The MobileSearch HE system offers two complementary imaging technologies
integrated in one system. Its 4.5 MeV high energy transmission X-ray generates
high penetration and high resolution images for the inspection of densely loaded
cargo, with typical penetration over 12 inches (300 mm) of steel. The system
also utilizes Z Backscatter X-ray imaging to assist in the identification of
organics for improved detection of explosive threats and other organic
contraband. Z Backscatter technology offers the additional benefits of
photo-like images and improved image analysis time, as well as a wide field of
view with no tire or ground cutoff unlike transmission X-rays - allowing for the
effective scanning of passenger vehicles and tires.

For added flexibility, the system offers multiple scan modes for high speed
scanning of passenger vehicles or oversized or odd-shaped cargo, allowing the
operational flexibility of the Z Backscatter™ Van - in either "drive-by" mode to
scan stationary objects, or "portal" mode to scan vehicles as they drive past
the system. The MobileSearch HE system also features a unique integrated cab
design that enables the drivers and operators to be in the same spacious cabin
for improved communications and comfort.
