thinking about entering the vault 34, but boone is wearing my space suit and i want to wear it when entering it, so i don't know if boone can get radiation poisoning. my guess is that companions can't get radiation poisoning?

Nope, companions can't receive radiation poisoning. So you're all set to use that space suit.

Sadly, no.

cheers guys. guess i gotta get well stocked up for the vault 34 battle

all you need is rad x and radaway you find these items in vault 34 anyway i didnt need the space suit
