When the lead bag goes through the x-ray (checked luggage) and they can't see inside, they crank the machine up as high as it will go. These machines are quite powerfull. They can see inside then and these is a good chance it will cause some fogging on any film.
If it is in the carry-on luggage, they will stop you and make you open the bag to show them whats in it.
