The best solution is to do what we can to raise awareness of photographic film and it's ability to be damaged by the new CT scanners, and thus have hand inspection of photosensitive materials standard across all civil airports in all countries.
I agree... since my main issue with hand checks has been the security personnel looking at me, and my ziplock baggie, with with eyes full of wonder, ignorance and suspicion. "Film?" "Pelicula?"
I assume the guys minding the line are not always in the same line, and most airports I go through frequently enough to notice still have both machines (CTs in whichever line was renovated most recently). For the sake of social engineering if all of us film travelers ask for hand checks every time, regardless of machine in that line, we will create awareness sooner...
And if it's more convenient, buy/process film on site, mail it home if domestic (radiography of international items is unpredictable), leave it in a vehicle you are shipping, etc.
*(I just realized that Spanish is the only language that I frequently encounter that has a different word. French, American, English, German, Romanian. Convenient, that!)
