I've requested hand inspection at British airports recently (Heathrow and Birmingham) and been refused. At Heathrow a few years ago they even asked me to remove the film from the 'film safe' bag and insisted on putting every film through the scanner individually. I objected and the security guard chucked a photocopy of a "which?" magazine article at me which claimed the scanners did no damage. I explained that they tested 100 and 200 ISO 35mm film - in metal cans. I had some Delta 3200 roll films with just backing paper. I would have had more luck trying to explain this to my cat. He can't speak English - but would at least have done me the courtesy of trying to listen...

So, be prepared in some airports to have everything put through the scanner. Bin Laden has a lot to answer for...

Having said that - I couldn't see any bad effects at all on my film afterwards
