High-tech science combats environmental hazards
U.S. Air Force Capt. John Lever, 446th Aerospace Medicine Squadron, bioenvironmental engineer out of McChord Field, Wash., analyzes a powdery substance with a hi-tech portable HAZMATID unit. HAZMATID bombards an unknown solid or liquid with infrared radiation and uses a database of 5,000 chemical makeups to identify a substance placed on it, delivering fast, dependable on-site analysis in the field. Bioenvironmental engineers can use these to provide incident commanders with immediate laboratory test results they can then use to make decisions that save lives. (U.S. Air Force photo by Staff Sgt.
