Does anyone think that the Capital Wasteland was hit by Neutron bombs as opposed to much in the way of traditional atomic weaponry? Neutron Bombs, for those who don't want to research them, are basically a type of nuclear warhead that went out of style due to the fact that it functions basically as a "radiation killer" as opposed to a "explosion killer."
The arguments against them is that they seemed more designed to kill civilian populations than regular nuclear bombs (a bit of a poor argument but I understand people who are horrified by the idea of "Super-Dirty" bombs).
I think this would go a long way to explaining why the Capital Wasteland is still so highly radioactive and yet primarily still intact. All of the populous of DC would have been killed nearly instantly but the structures would have remained largely intact.
What do people think?
