It looks to me that your film will be safe as long as it's been developed. But read the link for more info.

Best of luck!

that developed slide film would be okay. Maybe it’s implicit but that still seems like a risk.

That's about as close as you can get to a real answer, I think.

damaged by scanners, but I'm going on very old recollection.

Please let us all know what you figure out!

Most undeveloped film is also fine, going through modern American equipment. Some ultra-high ISO films *may* have some fogging problems if they are sent through multiple times (lots of legs of a trip, or taking the same film on multiple trips before processing, or through scanners at foreign airports (that may not be using the very low dosage that US airports use).

Here is an excellent article on the care, handling, and preservation of color slides:

Good info, now I can take these up north to share with my mom.

I haven’t traveled with film in a very long time. What I used to do is request a visual inspection at the checkpoint to avoid scanning. I assume they will still allow this.

If the film has been processed, it isn’t subject to damage from X-ray
