So I called the Athens airport and spoke to their security people who

A field test with voluntary checks of some 793000 passengers using
"naked scanners" in Hamburg, Germany, has just ended. The result, though
not officially reported yet, seems to be simply that the devices are
still expensive crap, at least those by L3.

The first software version showed the persons sort of naked, which is
not acceptable and was other than promised by L3. Next software version
showed only a symbol, but the alarms were anything but helpful. Too much
wardrobe, even long boots: Alarm. Passenger slightly moving: Alarm.
Two out of three scanned passengers had to be checked by hand, half of
those more than once (and nothing found, of course). L3 was not able to
deliver better software.

So, for the time being, no body scanners in Germany.
