Guam's International airport will this week get two advanced body imaging technology machines to screen passengers boarding airplanes
Brian Cahill of the Transportation Security Administration says passengers can expect to be screened soon after the scanners arrive.
He says the goal is scan as many arrivals as possible.
Mr Cahill says some passengers can opt out of using the scanner but they would have to submit to a pat-down.
There are about 540 imaging technology units at more than 100 U.S. airports, according to the Transportation Security Administration website.
