Abstract
A method and apparatus for screening an object for the presence of an explosive, chemical warfare agent, biological warfare agent, drug, metal, weapon, and/or radioactive material. The apparatus includes a portal through which the object is arranged to pass, the portal including a housing equipped with an ion mobility spectrometer and a surface acoustic wave device for detecting explosives, drugs and chemical warfare agents. In another embodiment the housing is equipped with a biological warfare agent detector, chemical warfare agent detector, metal detector, x-ray system, and/or radiation detector.
