    While the application of scientific knowledge creates technology, sometimes the technology is later redefined by science. Such is the case with terahertz (THz) radiation, the energy waves that drive the technology of the TSA: back scatter airport scanners.

    Emerging THz technological applications

    THz waves are found between microwaves and infrared on the electromagnetic spectrum. This type of radiation was chosen for security devices because it can penetrate matter such as clothing, wood, paper and other porous material that’s non-conducting.

    This type of radiation seems less threatening because it doesn’t penetrate deeply into the body and is believed to be harmless to both people and animals.
