I recently came back from India and including internal flights and even an xray scan at tourist site (making a total of 10 passes and making me a nervous wreck worrying about it) my iso 100 b&w and iso 200 slide film showed, to my eyes no sign of damage. My film was always in my hand luggage. I would never check film in as those scanners can be much more powerful. I chose slower film as I knew there would be virtually no chance of a hand check these days and I got the impression that some of the younger staff had no idea what film was. One guy wanted to know how I could see what I`d taken as my cameras had no screens on the back.
Hope this offers a bit of reassurance.
