Feasible mutant superpowers in a nuclear apocalypse setting

Hey guys, ive been thinking about making a setting with mutant superpowers as a result of radiation. Now I was thinking of making these powers not too fantastical and within some realm of possibility.

So far I have enhanced adrenal glands, poison immunity and emission, beneficial physical mutations such as claws and an extra eye.

What other somewhat feasible mutation based superpowers you think there are?
