It depends, Ilford SFX 200 could be okay but i wouldn't try Kodak HIE. if you want to get technical, Check the technical data for the film, it will give the sensitivity of the film in nanometers, then check the range of the x-ray. I would just ask for a hand search or carry them in your pocket and put them in the basket when you walk through. Happy shooting.(posted 8663 days ago)Karl
