This is a cross post from the other part of the forum - this is so confusing - but EU has not really set limits, they have put some guidelines in places so that more body scanners can be deployed all over Europe. Currently, in most European airports, there are none, just WTMD.
Wall Street Journal:
EU's Airports to Use Full-Body Scans
from the WSJ article:
"The new legislation legally allows member states and airports to replace current security systems with security scanners," the commission said.
from the AP article:
The European Union adopted new guidelines Monday on using body scanners at airports, hoping to address the privacy concerns that have delayed their implementation across the continent.
The only good thing about this is that they are apparently limiting it to MMW:
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.
I guess it depends on your point of view. I like the current system with WTMD much better, thank you.
