Japan will test new Hitachi walk-through bomb detectors that can pick up minute traces of explosives when the country hosts the Asia-Pacific Economic Cooperation summit next month.
The system blows warm air at passing passengers, and the air is captured by a suction device for chemical analysis of airborne particles. Explosives particles can be recognized within two or three seconds.
Still in the test phase, the system will be installed on November 12-14 at a train station in Yokohama near Tokyo. Passengers will be asked to help test the system.
