American Science & Engineering ( ASEI ) announced today that the government has awarded it an optionable contract to service and maintain, and provide spare parts for, its fleet of X-ray detection systems. These systems include airport devices for examining passengers prior to boarding, cargo inspection systems for use at ports, and even the company's Z Backscatter vans for mobile inspection of suspicious objects. The company said that if all options are exercised, the contract should be worth up to $12.4 million to the company. That would work out to about 6.8% of the company's annual revenues. link
