UV Lights Can Scan for Explosives in Baggage

Scientists at the University of Florida in Gainesville have developed an airport baggage scanner that uses ultraviolet (UV) light to help uncover explosives in checked airline baggage. The new system compares the specific colors of UV light absorbed as bags pass beneath the scanner along the conveyor belt. The new technology works with existing airport X-ray conveyor belts and, according to its developer, is able to scan 100 percent of luggage for explosives with 95-percent accuracy.
