Radiation is the ultimate bane of all organic life. Its particles punch holes in our DNA, causing mutations and giving us cancer. But, is there a way to make an organism that is unable to get radiation poisoning?
I don't want it to have something like the Tardigrade's tun, in which it dehydrates itself and becomes immortal, or some kind of lead scales that block the radiation.
I mean that the organism itself has some kind of natural process or characteristic that resists the effects of radiation entirely. As in, if a chunk of uranium was shoved inside its body, it would suffer no ailments whatsoever (aside from the ailments one would expect from having a large foreign object lodged in your flesh).
It wouldn't have to be an evolved trait, the creature in question could be a genetically modified organism.
Is this possible, or does radiation and life simply not mix?
