If you are refering to the mini nukes then no. They are roughly at my best guess about 1/4 to 1/2 megaton charge. to do full square city blocks it would have to be about 10 to 20 kilotons IMO only..........CAPITAL :nuke: WASTELAND
as for the topic well I am still finding out things about FO3 even after my 5th character..........:fallout:
Actually, 20 kilotons is less then half a megaton, 1000 kilotons in every megaton. Such as the Hiroshima bomb at 13 kilotons, so a mininuke mat be less then 0.0001 kilotons,
As for this you can see the discrepancy in "Megaton" when you set off the bomb, in reality a megaton sized explosion ( 76 times larger then the Hiroshima explosion which leveled an entire city ) would have made D/C a glass crater.
Now only if they had the tsar bomba. Russian nuke, largest ever detonated, at 50 megatons, or 3846 times larger then the Hiroshima bomb.
That explosion would have wiped the island of japan from existence.
And that was scaled back from the planned 100 megatons to minimize fallout.
