I was able to avoid X-ray exposure to all of my film (some of which was ISO 1600 that I was pushing to 3200) during a trip to Washington D.C. not long after the 9/11 attacks. At that time, all of the security checkpoints at the airports, monuments, etc. seemed to be on edge. However, by politely requesting hand checks of my camera and film I was always accommodated and never had my equipment X-rayed. Checkpoints that had swab based explosive scanners always utilized them during the manual checks. I was worried about the lower ISO film as well because going to ten different museums/monuments a day meant ten security checkpoints. I didn't want X-ray exposures to accumulate for even the low ISO film.
