What waves are used for security checks?

There are two types of full-body security screening systems currently (September 2010) used by the U.S. Transportation Security Administration (TSA) at airports: general-use x-ray and millimeter wave. With each of these products, a person enters an inspection zone and remains still while the images are created.

What electromagnetic wave is security inspection?

Millimeter wave security screening systems use non-ionizing electromagnetic radiation. There are two types of millimeter wave security systems: active systems that emit small amounts of millimeter wave energy and passive systems that sense naturally-occurring millimeter waves from warm bodies.

What waves are used in airport security checks?

As mentioned above, the United States uses millimeter-wave technology in airport security scans. This form of technology uses low-energy non-ionizing radiation that releases thousands of times less energy than a cell phone.

What waves do security scanners use?

Active scanners emit radio waves to produce an image. Passive scanners detect natural radiation emanating from the person. The main scanners in the active scanner category are millimetre wave scanners, which emit radio frequencies within the 24–30 GHz frequency range.

What frequency do airport scanners use?

These scanners typically operate in 10 GHz to 40 GHz range, and sometimes as high as 60 GHz to 80 GHz range as well.
