American Science and Engineering, Inc. Receives First Order for Z Backscatter
Van (ZBV) S-Class System for Spain Customs and Excise

Order Marks First ZBV System Deployment in Spain to be Used for Trade Fraud

BILLERICA, Mass., Jan. 14, 2013 (GLOBE NEWSWIRE) -- American Science and
Engineering, Inc. ("AS&E") (Nasdaq:ASEI), a leading worldwide supplier of
innovative X-ray detection solutions, announced today the receipt of an order
for the Company's top-selling, patented Z Backscatter^™ Van (ZBV) from Indra
Sistemas SA, AS&E's exclusive distributor in Spain, for use by Spain Customs
and Excise, a department within the Spanish Tax Agency. With this order, Spain
will obtain its first ZBV system, which will be used on their borders for
trade fraud interdiction of items such as cigarettes. This also marks the
first order for the recently introduced ZBV S-Class, which offers a reduced
operational footprint and a sleek, contemporary appearance.

"Spain Customs and Excise joins many of the world's most prestigious customs
and government organizations that rely on the ZBV system to regulate trade
fraud across their borders and collect unpaid revenue on smuggled goods," said
Anthony R. Fabiano, President and CEO of AS&E. "Our highly mobile ZBV
screening system has proven time and again its ability to safely and
successfully detect contraband, with many reported seizures of tobacco and
alcohol. With the ZBV S-Class, Spain Customs and Excise will have a more
streamlined chassis that provides added flexibility for scanning objects in
space constrained areas on their borders."

Z Backscatter Van (ZBV): The Number One Selling Cargo & Vehicle Inspection
System in the World

A breakthrough in X-ray detection technology, Z Backscatter Van is the number
one selling cargo and vehicle inspection system on the market, with more than
625 systems sold to more than 125 different customers in 57 countries. Since
its introduction in 2003, the ZBV system has consistently received the highest
marks for quality, reliability, and performance with a proven record of
detection results. The ZBV system is a low-cost, highly mobile screening
system built into a commercially available delivery van. It allows for
immediate deployment in response to security threats, and its high throughput
capability facilitates rapid inspections.

The ZBV system is used by leading government agencies, border authorities,
military bases, law enforcement departments and security agencies worldwide,
including: U.S. Customs and Border Protection on multiple borders; Abu Dhabi
Customs to safeguard borders; NATO Communications and Information Agency at
military checkpoints; Bulgaria Customs combating trade fraud on borders; Dutch
Customs Administration to scan empty airplanes; the Kingdom of Saudi Arabia to
protect a high-level facility; the Port of Venice to perform rapid inspections
of suspect vehicles; Tunisian Customs to combat trade fraud; customs security
for a Port Authority in Asia; and the Democratic Republic of Congo to fight
the illegal export of timber. The U.S. government has deployed hundreds of ZBV
systems for homeland security and force protection applications to detect
VBIEDs (vehicle borne improvised explosive devices), drugs, stowaways and
other contraband in war zones, military bases, and on U.S. ports and borders.

The ZBV system incorporates Z Backscatter technology — pioneered and perfected
at AS&E — and provides a single-sided configuration, small footprint, user
friendly operation, rapid scan speed and varied operating modes to provide
maximum maneuverability and flexibility for multiple applications.

The ZBV system is now available in three configurations — ZBV C-Class, ZBV
R-Class, and ZBV S-Class — to meet the diverse needs of ZBV customers:

  *ZBV C-Class: The original ZBV system built with a custom coach on a
    Mercedes-Benz^® Sprinter cab chassis.
  *ZBV R-Class: Built for rugged terrain, the Ford^® F550^® chassis offers
    4WD, additional ground clearance and a crew cab for extra space.
  *ZBV S-Class: The newest addition to the ZBV line, built in a standard
    Mercedes-Benz Sprinter panel van for a contemporary appearance and with a
    reduced operational footprint for scanning objects in the tightest
