Hello to all,
In a week from now I'll be going for a long trip across Eastern Europe and will be carrying close to 100 rolls of film. My worry is how to protect film from x-ray machines at the airport (3 flights to get there then 3 flights back). Most of my film will be T-max 400 but I'll have around 20 rolls of Ilford Delta 3200.
What do I do? Those protection bags are apparently good for up to 400ASA?
Any tip would be highly appreciated.

Thanks a lot,
