Trying to figure out the most rational thing to do at each distance. In fireball, say goodbye. Sounds like shock wave isn't that big of a deal on its own far beyond the fireball region, beyond eardrums, but obviously shrapnel and collapses will get you indirectly. But thermal radiation seems to extend much farther per the website and there's no escape. So is that what actually kills the most people? (Though it's 2017, who ever goes outside anymore?) And then of course fallout, but I guess you can flee or shelter from that.
