Narrator: This is Science Today. In an effort to protect the nation from radiological or nuclear attack, physicists at the Lawrence Livermore National Laboratory have developed a portable radiation monitoring system. Nuclear physicist Dan Archer, says the Adaptive Radiation Area Monitor, or ARAM, can detect small amounts of radioactive materials from a distance and at speeds up to 60 miles per hour.
Archer: We developed the radiation detector system such that you could scan for radioactive material moving at highway speeds or pedestrian carry speeds or toll booth type speeds or packaged speeds on a conveyor belt, but the real novelty in this is being able to find very, very small amounts of radioactive material moving at sixty miles per hour down the road without ever having to slow the traffic down.
Narrator: The system was demonstrated successfully at Federal Express in Denver , and used to scan traffic in a major city. It has also been used as part of a larger network.
Archer: It's a commercially-available technology being used across the country, from coast-to-coast.
