JUNEAU -- The Juneau airport this week will join Anchorage and Fairbanks in requiring passengers to go through full-body scanners, according to the Transportation Security Administration.

The new Advanced Imaging Technology scanners will be demonstrated to local news media on Thursday.

As in Anchorage and Fairbanks, the scanners do not produce an actual image of the traveler being scanned. Instead, the scanner's software displays a generic, gray human form and indicates any concealed metallic or nonmetallic objects that might be under the traveler's clothes.
