I'm not sure either. It's not an air tight bomb shelter and it's used like an average storeroom, storing stuff like winter jackets, suitcases and paint. I do use small amounts of Calcium Chloride based dessicants to keep the room dry.
Have you checked for Radon?
Radon is a noble gas and chemically inert. It's radioactive, which is why it's a toxicity worry. But there was enough radiation in that basement to mechanically damage plastic in three years, OP would be long since dead.
Radon and its progenitors won't produce nearly enough radiation to damage plastics like that at naturally occurring levels.
Water based or solvent based paint?
Should be solvent based.
If it's underground at all, check for radon.
Radon is a noble gas. It's not going to affect fiber or wiring... but yes, if you're going to spend much time down there, definitely a good idea to check for it.
Radon is radioactive. The alpha particles it emits can break down polymers and degrade plastics.
