Last month I travelled from Dresden to London Heathrow and back to Frankfurt. I had a piece of Neopan 1600 film with me which shows a gray horizontal line, about 5-6 mm wide, told the security stuff, what I would have high speed films with me, not suitable for X-ray. In Dresden they had a quick look in this small plastic bag, because they have never heard of 3200 films. At London one officer opened every plastic canister one by one, but not removing the film from it.(posted 9000 days ago)In my cameras I had Plus-X and 200 colour slide, which went thru the hand lugguage X-ray. No problems.
Konica 750 and SFX 200 are not that sensitive to light, so try a hand check. Kodak I would rather risk the hand lagguage X-ray, than open the box in bright light.
I suppose the X-rays in Germany are not that strong.
