NYPD Radiation Scanners Also Detect Concealed Weapons
High-tech device sees through clothes to highlight guns.
To tackle the problem of illegal handguns, the NYPD has began testing new technology that uses radiation to reveal a concealed weapon from a few meters away. The scanner can detect gun carried by criminals without having to use the pat-down procedure.
The machine is able to read terahertz, which the natural energy emitted by people and inanimate objects. Police Commissioner Raymond Kelly explained that, “If something is obstructing the flow of that radiation, for example a weapon, the device will highlight that object.”
