The newest security screening device, a full-body scanner, is now in use at the airport in Saskatoon.

Travellers who are directed to a secondary screening are being given the option of a pat-down by a security agent or to have their body scanned by the device, which can see through clothing.

"Physical pat-down can be quite intrusive and some people are not very comfortable with that," Bill Restall, president of the Saskatoon Airport Authority, said about the option for a body scan. "Whereas [with] this, you're not touched in any fashion."

The scanned images are reviewed in a separate area of the airport, where an officer looks at the pictures.

"Yikes ... I definitely wouldn't be comfortable with that," traveller Lorie Clark told CBC News when asked about the new system.

Others were not concerned, so long as the picture does not go beyond the security room.

"It's not like they're going to put it on the Internet," Brad Acton, another passenger, noted. "It's not that great of a body, right? So I'm not too worried about it."

According to reports prior to the installation of the devices, the scanners cost $250,000 each, including parts and training.
