Carry film through electronic airport inspections?

In two weeks, I will be flying to Alaska from Baltimore, with two stops in between. This means I might have to pass through electronic inspection points three times. How do these inspections affect photographic film? I will be carrying rolls of Kodak ISO400 & 800 film and Kodak Portra 400 film.

Thanks, in advance,

Roy

400, 800, speed film is a bit more sensitive. I think there is a sign that 400 is Okay, but I would not trust it if you need absolutely clean film. It would be better to have it hand inspected. It would probably be okay for most purposes to just let it go through, but just to be safe, hand it to the folks at the check-in.
