Nuclear war is catastrophic in any case.
Definitely. I live about 15 miles from the centre of London. I'd have died in a nuclear exchange.
Actually, you would have been just fine* (unless there was something in your area worth nuking). cite
*depending on you define "fine" and how big the nukes are of course. The bomb in the link is twice as big as what the Topol M carries. You'd only recieve "Light damage to all structures, and light to moderate damage to ordinary houses, will occur within this ring." On the other hand, if London was anything like high value American targets (which I'm sure it was/is) it wasn't going to get hit with just one. Last I heard the plan was to nuke very high level targets every 5 minutes for an hour. Obviously that would be impossible as the Russians ability to deliver nukes would be virtually nonexistent in short order. I don't know what direction from London you are or what the prevailing winds are....you'd certainly want to be upwind.
I'm ENE from the centre of town.
Not if we're talking the full 20 MT option for the R-36M/SS-18, that's for sure.
