Including the radioactive zombies, spreading nuclear fallout all over the place isn't worth killing off only 7.84% of the US population, but it is an interesting thought experiment. That is if the explosion kills them, but anyone outside the blast radius would basically be a radioactive zombie. Which is WAY worse than a regular zombie.
