The chances are extremely low. FCO is running a current short term test using the 'new' technology which does not show the images the previous poster stated. http://www.flyertalk.com/forum/trave...pting-out.html In HAM (where there is an optional test) and at AMS one does not have to use the scanner if selected.

There are no scanners at FRA and MUC. Here is an example of what security is like in Germany. http://www.flyertalk.com/forum/archive/t-1215641.html

Canada does have scanners at some airports for international departures, but I have never seen them in use, and there is the option on the very low chance if one is selected to take the very tame pat down instead. It is nothing like the US pat down.
