Has anyone actually experienced damage to camera film from airport x-ray scanners?

I recently came back from a trip after carrying unexposed film once in my checked hold luggage and once in my hand luggage, so it's been through the regular scanners and also the (apparently more powerful) hold luggage scanners. It's 800 iso, so according to everything I could find online it should've been cooked. But it wasn't: photos came out completely fine.

Has anyone ever actually had a problem with airport x-rays or is this all just a meme?
