Not if you bury it in regolith. That’s an idea for a Lunar base too. The design is called “Hobbit holes.” Bury the occupied structures in piles of basically any local mass you can bury them in.

It’s another huge problem for orbit though. Shielding would add a ton of mass and destroy the economics.

We will need to develop very robust, space-worthy electronics eventually. We can't rely on natural magnetic fields forever.
