X-ray machines affect your film. It’s good to keep it in your carry-on instead of checked baggage, but the best option is to ask a security team member for a hand-check instead.
Film in checked-in luggage will be most likely affected.
In the past, the carry-on x-ray scanners did not damage the film. But since the end of 2019, new scanners are being installed in certain airports. These scanners damage the film as they do a 360° scan using a higher radiation dose. Therefore, we recommend having the film hand-checked. This will guarantee that the film is not damaged by the radiation.
Damaged film typically shows a pinkish hue and a washed-out, foggy look throughout the photo. Great if you’re a fan of all things pink, but not so much for everyone else.
A note about exposed film (film you’ve already exposed) is completely unaffected by x-rays, so it will be fine in any baggage.
