Full body scanner in millimeter wave scanners technique at Cologne Bonn Airport Image from an active millimeter wave body scanner. A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact.
The efficacy of millimeter wave scanners in detecting threatening objects has been questioned. Formal studies demonstrated the relative inability of these scanners to detect objects—dangerous or not—on the person being scanned. [28] Additionally, some studies suggested that the cost–benefit ratios of these scanners is poor. [29]
In 2009, the US TSA introduced full-body scanners as a primary screening modality in airport security, first as backscatter X-ray scanners, which use ionizing radiation and which the European Union banned in 2011 due to health and safety concerns. These were followed by non-ionizing millimeter wave scanners. [39]
In the wake of the recent incident on a Northwest/Delta flight over the holidays, the Transportation Security Administration (TSA) has been working to develop more comprehensive security scanners.
Airport scanners have come a long way. ... In the future, this technology could be further enhanced by AI to detect threats at a much faster rate. Hypothetically, CT scans could also be used for ...
Two respected scientists say they have discovered a flaw in airport full body scanners that could potentially allow terrorists to outsmart the
Unlike cell phone signals, or millimeter-wave scanners, the energy being emitted by a backscatter X-ray is a type of ionizing radiation that breaks chemical bonds. Ionizing radiation is considered carcinogenic even in very small doses but at the doses used in airport scanners this effect is believed to be negligible for an individual.
