Proven to be a highly effective means of detecting dangerous items such as weapons and explosives, the TSA has installed several Advanced Imaging Technology (AIT) machines at OKC Airport. The machines are called millimeter wave and use harmless electromagnetic waves to detect items that could be a threat. The energy projected is thousands of times less than a cell phone transmission. These machines do not display specific images of a passenger’s body, only a generic outline that is the same for everyone.
The millimeter wave technology meets all known national and international health and safety standards. The screening is safe for all passengers, including children, pregnant women, and individuals with medical implants. AIT screening is optional; however, if a passenger chooses not to use the machine, they will receive alternative screening and may include a physical pat-down.
The procedure for using the AIT is simple: A passenger steps into the imaging portal, stands in position for a few seconds while the machine creates an image, then steps out. Should the machine detect an item concealed under a passenger’s clothing, the machine generates a generic image, similar to a gingerbread man, with a box around the area of concern. At that point, a TSA officer determines if additional screening is needed. If the machine detects no anomalies, a green box with the words “OK” appears on the screen. The entire process is conducted in the presence of the passenger.
