TSA will make additional airport announcements as plans are finalized. Many factors are taken into consideration before AIT units are deployed including airport readiness and checkpoint infrastructure.

AIT is designed to enhance security by safely screening passengers for metallic and non-metallic threats — including weapons, explosives and other objects concealed under layers of clothing.

Imaging technology screening is safe for all travelers, and the technology meets all known national and international health and safety standards. In fact, the energy emitted by millimeter wave technology is 1000 times less than the international limits and guidelines.

In September 2011, TSA purchased 300 millimeter wave units, which are being deployed in the coming months. Currently, there are nearly 500 AIT units at 78 airports nationwide. President Obama’s fiscal 2011 budget included the purchase of 500 units, and the President’s fiscal 2012 budget requests funding for an additional 275 units.
