All, Here's a question regarding a bit of fiction I am writing as a side project.
What would the radiation effects be of a hypothetical pure-fusion nuclear weapon? That is, a nuclear bomb containing no fissile material whatsoever, triggered by some other means. The following scenarios are used in the storyline, and I'd like to get the physics reasonably correct: 1. Moderately-high altitude detonations over sea and/or largely uninhabited areas, with intent of destroying American, Russian, Chinese launched ICBMs, aircraft squadrons, etc. How much fallout (if any) is produced by the pure-fusion device, and will remains of the intercepted fissile-material-containing missiles cause fallout? I would assume it would. 2. Air blast of pure fusion weapon over land, for example, a city. Fallout? Neutron activation? How bad would this be, and would there be some fusion reaction schemes that could mitigate neutron activation? 3. Same as above, but a ground blast of the fusion weapon. Again, I'd assume neutron activation would be a factor, and is there some way to minimize it? Thanks in advance, --Kyle
