Actually, the expression RIG refers to the blue bar that tracks Isaac's health, but that's neither here nor there. Like i said in my second reply to this, each suit is protective against whats its designed for. And the suits DO provide radiation protection considering that they all can go into vacuum, where there's a lot more radiation then on Titan Station or Tau Volantis.
