Protecting small electrical appliances from solar radiation?

Question

Electronics

Hey! It is said that in the near future the planet may suffer from cosmic radiation. In addition, the Earth's magnetic field will probably weaken, for example, there is a lot of information about the same inversion of the Earth's poles.
I want to create something like a camera that would protect small appliances from electromagnetic radiation in the house. What will be effective for this? Useful articles, real examples?
I think this is a do-it-yourself question. Please do not write about the stupidity of the idea and other things, everyone decides for himself. I would be grateful for any hints
Thanks in advance

Answer 1

Cosmic rays and gamma particles can be protected by digging deep underground, but there will be no 100% protection. The safest thing for electronics is to just turn it off for the duration of the flash so it doesn't set itself on fire. And turn it off completely, de-energize.

Answer 2

foil hat.
literally and figuratively.
