Abstract

Suicide bomber attackers with improvised explosive devices hidden inside their body cavities may be a new danger to air transport security. Metal detectors, passive and active millimeter or terahertz waves imaging, x-ray backscatter imaging and portals for race particles detection are not sufficient for detection of explosives concealed under thicker layer of material with density and dielectric properties like human body. Through x-ray imaging is problematic for public health regulations and so only nuclear quadrupole resonance seems to be the solution.
