SAN LUIS, Ariz. - There's a new screening process coming to the Port of San Luis.
U.S. Customs and Border Protection is making a technology upgrade and has begun construction on the new Z-Portal.
CBP says Z-Portal drive-through inspection imaging system quickly produces images from three sides: left, right and top-down. This examines the vehicle and results in a comprehensive and improved capability to detect suspicious items while helping the flow of traffic.
The technology uses inspection tools including gamma-ray and X-ray non-intrusive inspection technologies.
CBP says a person would have to go through the Z-Portal more than 2,000 times to get the radiation exposure of one medical chest X-ray.
In comparison to the technology currently being used by CBP, the Z-portal gives a much clearer image of low density objects that could be hidden in car fenders, tired, trucks, gas tanks or under the hood.
