Had Little Boy and Fat Man burst at ground level, the situation in
Hiroshima and Nagasaki would not have been nearly so mild.

If it had been a surface detonation, the damage would have been
substantially LESS.



Damage maybe, but not future liveability.

Hiroshima and Nagasaki were liveable after 5 years.

Chernobyl reportedly wasn't even a nuclear explosion, just a steam
explosion... but it carried nuclear material from the surface over a wide
area, and is still basically unliveable 20 years later.
