AS&E's OmniView Gantry Deployed at the Port of Charleston will be Featured on a Port Tour and Exclusive Briefing by Port Security Officials

BILLERICA, Mass. -- American Science and Engineering, Inc. (AS&E[R]) (NASDAQ: ASEI), a leader in X-ray detection technology, announced today that it will present a cargo inspection discussion and participate in a product tour at the 6th Annual Maritime Homeland Security Summit, sponsored by the Institute for Defense and Government Advancement (IDGA), to be held March 31st to April 2nd at the Kiawah Island Resort in Charleston, South Carolina.

At the Summit, AS&E's Vice President of U.S. Government Sales, John Chrisos, will discuss "New cargo inspection techniques to improve scanning efficiency, detection and deterrence" in a presentation to be held Wednesday, April 2nd at 1:55 p.m.

In addition, port security officials will demonstrate AS&E's OmniView Gantry cargo inspection system as part of the Summit's Tour and Special Exclusive Briefing at the Port of Charleston on Monday March 31st. The Port of Charleston, considered one of the busiest (by cargo dollar value) and most productive ports in the United States, utilizes the OmniView Gantry to inspect high-risk containers for explosive threats and contraband. The system's high penetration capability enables the port to inspect very dense and complex cargo while providing a rapid cycle-time for inspection.

"AS&E is very pleased to have an active role in an important port security event such as the Maritime Homeland Security Summit," said AS&E's John Chrisos. "We are honored to discuss and demonstrate the best practices and strategies for safe, efficient containerized cargo inspection to secure our nations ports."

OmniView[TM] Gantry Cargo Inspection System

The OmniView Gantry System provides 6 MeV high-energy transmission inspection for high penetration into inspected objects -- up to 14 inches (350 mm) of steel -- yet the system does not require an exterior building or heavy shielding. The OmniView Gantry System's scanning platform operates by moving on rails past stationary vehicles and cargo. The system is bi-directional allowing for a high throughput of approximately 2 trucks per scan, 24 trucks per hour.
