American Science and Engineering, Inc. Introduces New Gemini Parcel Inspection Systems in a Variety of Sizes for Superior Threat Detection

Gemini's Unique Combination of Z Backscatter and Dual-Energy to be Demonstrated April 1-3 at ISC West 2009 Las Vegas - ISC West 2009 Booth #38026

American Science and Engineering, Inc. (AS&E®) (NASDAQ: ASEI), a leading worldwide supplier of innovative X-ray detection solutions, announced today the introduction of two new Geminiâ„¢ Parcel Inspection Systems: Gemini 7555 and Gemini 100100. These systems along with the Gemini 6040 provide customers with a selection of systems to inspect everything from mail, baggage and break-bulk cargo within mailrooms, lobbies, checkpoints, airports, high threat facilities and other security-sensitive areas. A Gemini multi-technology system will be demonstrated at ISC West 2009 in Las Vegas, April 1-3 2009 in AS&E's Booth #38026.

Gemini continues to be the first and only conventional parcel inspection system to combine multiple technologies — AS&E's proprietary Z Backscatter™ X-ray technology and dual-energy transmission — allowing operators to obtain the most information about the contents of a parcel. Operators simultaneously view two images, a Z Backscatter image and a dual-energy image, dramatically increasing the likelihood of finding hidden illegal materials. Gemini's unique capability to detect both metallic and non-metallic threats — even in cluttered environments — makes it an invaluable inspection tool for security officials.

"With the introduction of additional Gemini systems, we are broadening our offering of the only proven multi-technology X-ray solution for screening parcels," said Anthony Fabiano, AS&E's President and CEO. "We believe that Gemini's combination of Z Backscatter and dual-energy transmission provides the most attractive value proposition for parcel inspection available today."
