For the film industry I'd be more worried about Strontium-90 [2] that has a half life of 29 years, so it can survive long enough to get collected, processed and used.
<<Tim, Thanks for this article and I think you did a great job on a very important but little known topic. I've researched this quite a bit and I'm certain it was cerium-141, not iodine-131, that was lodged in Kodak's packing material that fogged their film, and the packing material was strawboard, not corn husks. (There's some disagreement on the internet - even a U.S. senator who had misspoken on the facts - but if you really dig deep, you'll find it was strawboard.) >>

"American children were actually exposed to 15 to 70 times as much radiation as had been previously reported to Congress."
The same article mentions the Kodak story ("The physicist's knowledge of the secret project was not altogether surprising: the Kodak Company ran the Tennessee Eastman uranium processing plant at the Oak Ridge National Laboratory") and has many more valuable and relevant details.
