Are there any in-lore examples of extremely ghoulish features with minimal physical mutations?

I would say your character could get by just being lucky. If there's anything more lore friendly to fallout it would be that you were lucky enough to have resistant genes.

I'd go all out and say my family had been uranium miners for generations and were pioneers to the industry. That had phenomienal effects on your family mostly via the luck of the draw. This could also make you a desirable partner romantically (though I know thats not the perrogative during most rp sessions) and could play into other paycological attributes your characters has like bravery or endurance or general know how (common sense).

I love hearing about original characters! It's even more fun when you get to play in a familiar place! I hope this helps a tiny bit in making it all feel more immersive.
