I might absorb a lot of the gamma radiation, but that's going to cause the hull itself to heat up and it can cause it to break apart as well. I'd wager that a kiloton nuke going off 100 meters from your hull is going to cause serious problems to both the hull and the crew inside.

True; the primary killing system is the sleet of radiation the device produces. There was a lot of work done on the design of space-initiated nuclear devices back in the old days of Nike-Zeus. The designs used a lot of tricks to up the radiation yield at the expense of the blast and thermal effects. One of them was to wrap the device in gold foil. The "explosive" effects of an initiation in space are astonishingly limited; 100 meters probably would protect a reasonably heavily-constructed space ship from damage from a 1 kiloton initiation. Unless the warhead was heavily doped using tricks, I believe the hull would provide enough protection to limit radiation damage to the crew. In Balance of Terror, the nuclear device used was IIRC a scuttling charge. So it was probably a pretty conventional device.
By the way. most of the radioactive product from an initiation comes from debris being sucked into the fireball. That ain't going to happen much in space. We never really worried much about gamma. If blast and flash are going to reduce a victim to the size and appearance of a McDonalds hamburger, irradiating them as well isn't a productive use of resources. As a friend of mine put it, it isn't the explosion that kills you, its the fall to the bottom of the crater.
