Sort of like a fusion bomb, the fusion bomb doesn't produce radioactive fallout, but the fission bomb necessary to start the fusion bomb does.

Aneutronic fusion is possible, but requires collision energies much higher than what ITER is designed to create.
EDIT: I do wonder if there's a danger of nuclear proliferation with using fusion reactors to breed plutonium from natural uranium, though.
If you set it off near the ground many of the escaping neutrons will interact with things that get very angry when activated by a stray neutron. A big bomb detonated near the ground, to crack open a bunker for instance, can send stupendous amounts of fallout into the air and kill people hundreds of miles down wind of acute "vomit now and die in a week" radiation poisoning.
EDIT: see other comment, DT produces neutrons which can be bad, I still think the amount nastiness is small compared to say Chernobyl.
Tritium is something like 10 orders of magnitude more radioactive than uranium (in terms of its specific activity). Uranium itself is so low in radioactivity that the bigger risk when handling it is heavy metal poisoning. The by-products of fissions are much more radioactive, though.
