Please look under my gallery for an image I posted of an ocean scene. It was 100 speed film that went thru the carryon scanner at an airport scanner ONE TIME! It has very distinct scan bars through the whole photograph.

They say it will not hurt anything below 800...WELL IT CLEARLY RUINED A WHOLE BOX OF 8x10 sheet film in 100 speed!

Dont trust those people. Just send your film by mail where it is not scanned with Xrays.
