That seems incredibly fast for plastic to degrade like that. I wonder if you could have something generating ozone in there.

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 and its progenitors won't produce nearly enough radiation to damage plastics like that at naturally occurring levels.

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.

Water based or solvent based paint?

alienchow 13 hours ago | parent [-]

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.

Interseting - I have high radon (mitigeted in the house via a fan), if I burry fibre what will I need to do to get something that will work? I have an outbuilding that I want to give internet.

No, radiation from radon at naturally occurring levels won't cause any damage to plastics.

If it were radioactive enough to do that, you'd have a much bigger problem than some networking flakiness.

I don’t disagree but your comment made it sound impossible which it isn’t.

CamperBob2 4 hours ago | parent [-]

It absolutely is, for all practical purposes. Alpha radiation won't go more than 100 um or so into plastic.

My first thought exactly. I know someone who inadvertently melted a ton of stuff with overuse of an ozone generator, similar kind of effect
