Same as storage: keep humidity and temperature low.

POP emulsions use very fine grain emulsions, which have a
particularly poor sensitivity to x-ray, gamma ray, cosmic ray,
beta particles, etc. I can imagine the emulsion may print out
if you irradiate with low energy electron beam or alpha
particles of any energy level, or a very high flux of any
radiation, but otherwise, these radiations do not print out
image like UV light.

I don't want to be held responsible, but I don't think this is
an issue. I would not put any material for development process
to a powerful x-ray scanner, though.
