American Science and Engineering, Inc. Awarded IDIQ Contract from TSA For SmartCheck Personnel Screening System

American Science and Engineering, Inc. (AS&E®) (NASDAQ: ASEI), a leader in X-ray detection technology, announced today it has been awarded an Indefinite Delivery Indefinite Quantity (IDIQ) contract from the Transportation Security Administration (TSA) for its SmartCheck™ personnel screening system. With a maximum value of $10.8 million, the first phase of the IDIQ has been funded for the lease of five (5) SmartCheck Personnel Screening Systems with an option to purchase. The IDIQ contract also provides TSA with an option to purchase an additional seventy-five (75) SmartCheck systems over the next two years. The IDIQ contract includes warranty, service and training. "We are extremely proud to assist the TSA with their mission to safeguard air travel,” said Anthony Fabiano, President and CEO. "This IDIQ offers TSA the ability to deploy our SmartCheck personnel screening system on a broad basis for use as a safe and effective tool for aviation threat detection. SmartCheck provides the most comprehensive personnel screening technology available for detecting a broad range of potential threat items while ensuring the privacy of the traveling public. We look forward to our continued work with the TSA on this critical mission.” About SmartCheck SmartCheck is a safe, non-intrusive personnel screening system that allows operators to detect threats and contraband hidden on a person while ensuring privacy. AS&E’s patented Z® Backscatter™ X-ray technology displays both organic and inorganic materials, revealing objects such as guns and knives, explosives, composite weapons, and other hidden threats and contraband. The software provides a sketch outline of the passenger with information for the security operator to identify the nature and location of threats, thus eliminating the need for intrusive and time-consuming pat-down searches. For added privacy, the system is not capable of storing, exporting, printing, or transmitting images. All images are automatically deleted from the system immediately after they are reviewed by the operator who is located in a remote, secure area away from the screening process. About SmartCheck’s Z Backscatter X-Ray Technology Z Backscatter X-ray technology displays threats by reflecting a low-energy X-ray beam from a person to a detector on the near side. AS&E's SmartCheck system utilizes this patented technology based on the X-ray Compton Scattering effect. The system is able to display organic and metallic threats and contraband concealed on a person's body. Safe for All Screened Individuals and Operators Since the SmartCheck system uses Z Backscatter X-ray technology, it is safe for both operators and scanned individuals, with the radiation dose from a single scan equivalent to the radiation received from two minutes of airplane flight at altitude, or less than 10 microrem (0.1 microsieverts) per scan. SmartCheck meets the manufacturer’s requirements of the American National Standards Institute (ANSI) standard N43.17, which is the standard that the Center for Devices and Radiological Health (CDRH) references for systems such as SmartCheck.
