X-Ray Damage to 500T in Film Stocks & Processing Posted December 7, 2005 I shot about (6) 100' rolls this Thanksgiving of family stuff. (3) Vision2 500T, (2) Vision2 50T and (1) B&W Negative. I was visiting relatives in North Carolina so I had to fly from Dallas. I shipped the film there with DO NOT X-RAY all over it. After shooting, I was in a hurry and threw the film into my suitcase thinking that maybe the whole X-Ray thing was a myth anyway. Boy was I wrong. The 500T came back with a pulsing fog. Since I shoot with a K-3 I'm never quite sure if it's the film or the camera but the lab guys looked at the transfer and agreed it was probably X-ray damage. The 50D came back fine and looked truely amazing... the colorist said it was the first time she worked with this stock and it was wonderful. No damage was visable. So, if the bags did get zapped by a powerful x-ray, what would be the general limit to the speed of film so it wouldn't show damage? Of course in the future I will send everything FedEx with DO NOT X-RAY all over it.
