Odds are they'll require all devices to go through the scanners, because officially, they cause no damage.
From the TSA's Packing Tips page:
TSA will screen any "Carry-on" baggage that will fit through the x-ray machine;
However, looking at that, there are a few points that some stuff could get damaged:
Don't put film in your checked baggage, as the screening equipment will damage it.
And they have a way around inspection by x-ray for those sensitive items:
Put all undeveloped film and cameras with film in your carry-on baggage. If your bag will pass through the X-ray machine more than five (5) times ask for a hand inspection to prevent damage.
So hand inspections are indeed possible.
Finally, IF by some horrible luck, you get something damaged, they have a page on how to handle this (claims etc). I link to TSA, but assume most screening organisations around the world will be similar.
