You might find they are no good.(posted 9236 days ago)Not based on personal experience, but I have read that with its high speed, this film is very suceptable to natural background radiation of some sort.
Supposedly (and take this with a grain of salt...), all these sensitive emulsions and papers are stored by Kodak in an abandoned salt mine, where they are protected from whatever effects. They are shipped out at peak condition and don't last too long.

Run some tests?
