Radon is radioactive. The alpha particles it emits can break down polymers and degrade plastics.
If it were radioactive enough to do that, you'd have a much bigger problem than some networking flakiness.

Original Gameboys are military grade, and even in the gulf war when they were used, there was one that survived being melted.
Used for what?

I don’t disagree but your comment made it sound impossible which it isn’t.
Coiled up high-speed fiber optic cables suffer data-abrasion due to centrifugal forces. Either reduce data speed or arrange those cables in straight lines with space-grade angle connectors.
Worse still, the loop-de-loops can make your packets dizzy which is an unpleasant experience for anyone doing a video call with you and makes games such as VR chat completely untenable.
If you ever experience this, but can't uncoil the transmission cables, a workaround is to spin your desk chair in the opposite direction of data flow, at about the speed of light (for the respective cable medium). This temporary cancels out the effects of ethernet frame looping induced dizziness. Alternatively, you can treat any sickness symptomatically by chewing on a piece of ginger. The latter also helps with aforementioned data-abrasion in fiber optic cables through means not fully understood, yet.
I’ve had this failure on soft-touch usb cables from the 2000’s, not related to movement, just in a box in room temperature storage they disintegrate like this. It was described to me as thermoplastic elastometer degradation but I’m not really satisfied with that vague of an answer. Main comment thread when I first jumped in to discuss it: https://news.ycombinator.com/item?id=28054090
I have a couple of USB cables from the 2000's like this, some of them original apple cables. But most are fine. While some show brittleless, more plstics goes gooey and tarry - especially some ABS coating that makes the material more grippable,like computer mice or binoculars.
Thanks HN folks for all the comments. To clarify a bit, the cables are pulled through PVC conduits under the flooring before being buried in cement. Currently the hypotheses for why the cable disintegrated so quickly is hydrolysis and paint solvents. Singapore is extremely humid but this doesn't explain why the exposed cabling on the other end is still healthy and not crumbly. The second possibility is that I keep th…
if you're using 25gbps/sfp28 transceivers, you probably have FEC. if so, you probably have both correctable and uncorrectable error counters to look at.

What’s the advantage of using fiber optics for home networking over 10Gbe Ethernet?
For me, I wanted my networking to be future proof over the next 25 years if Im going to be putting all that work in to wire up the house. My ISP already offers 5Gb/s upstream and will most likely offer 10Gb/s in the coming years.
If you buy a consumer product labeled "military grade" you are buying snake oil. And not just snake oil, incredibly over priced snake oil.
Is one supposed to send it back for a refund and order the much thinner, less-durable cable? Or is perhaps the landscape not as black-and-white as your "this is automatically snake-oil"?

Mini Cooper. From what I've heard it's a BMW thing.
BMW and Toyota have famously used bio-derived insulation reported to be like catnip for rodents. The bio-oil plasticizers also migrate out more quickly in thermal cycling than the old dead dinosaurs approach. Hilariously, when I asked my mechanic about getting an M5, he laughed and explained that the radiator components are known to turn brittle and crack after 5-6 years because of this. (I don't envy automotive folk…
