There are no fusion only bombs. (To be fair, there are a few designs for them, but those are theoretical. The so called neutron bombs).
This is what I said. Hydrogen bombs use the energy from the atomic bomb for a fusion reaction, which produce the thermonuclear explosion. I have a bit of doubt about from what reaction comes the most power, because that's not exactly what tells me other sources, nor correspond with the development "booster" and "super" design. But there's no really public studies about it.
Actually, I've been surprised to find out that neutrons bombs exists, but are not as inefficient. They use the same design as hydrogen bombs (so, with an atomic bomb too), but release the neutrons which makes it more aggressive towards organic and electronic, but with smaller explosion.
Now, deuterium-tritium reaction, which is the considered reaction (I've seen nowhere talking about H² He-3 reaction, nor about "catching electron from reaction").
Deuterium : 1 proton, 1 neutron
Tritium : 2 neutron, 1 proton
When combined, they'll form a 2 neutrons, 2 protons (Helium), and a free neutron. The helium is not radioactive. But the neutron (not radioactive in itself), if absorbed by other particles,
can often make the said particles radioactive, like the inner plating (which will then be radioactive waste).
Neutrons in itself are not radioactive. Of course, it's dangerous for (as said), organics, as if you become radioactive yourself (do not try this at home), but on other materials, it change them into radioactive waste (most are not very dangerous, but some can be nasty).
For more things about radioactive effects of neutrons.From what I saw about tritium, there is currently an unused stock from current nuclear (fission) plants which will not be enough for future or electricity use. That's why they are trying with ITER, to produce tritium, within the reactor, with lithium and the help of said neutrons.
Fakedit : I'd rather be pessimist and surprised, than be optimistic and dissapointed.
