The European Union adopted new guidelines Monday on using body scanners at airports.

Under the new EU law, security scanners must not store or copy any of the images, and the security staff analyzing the images will be in a room separate from where the actual screening is conducted. In addition, passengers must be informed and be given the right to choose an alternative method of screening.

And in order not to risk citizens' health and safety, only security scanners that do not use X-ray technology can be used at EU airports.
