in france you can request the police to hand check the film I did this very recently.
You can also get a fake sticker that says the film is inferred film which can not go through the x-ray machine. The countries I have had no luck at all with hand checks are England, Italy and Canada. Holland, France, USA, and China were ok (some after a lot of explaining). Heathrow, Manchester and Gatwick were 'no way' even if it was inferred.
In the UK and most places Fed Ex x-ray everything. DHL in the UK if you go directly to the sorting office they hand check as they do not have the x-ray machines (especially in more provincial towns).
I have put film through and it was fine, but the thing is its a risk, and the film that I had fogged was 100 asa.
these stickers are handy http://motion.kodak.com/US/en/motion/Education/Publications/Shooting/xray.htm
