Nonfiction books on what happens after a nuclear bombing / disaster.

I read Nuclear War: A Scenario by Annie Jacobsen recently, and while I really enjoyed it, I was looking for more nonfiction on this subject that would focus more on a civilian perspective, rather than the inside baseball of governmental strategies. I'm waiting for The Doomsday Machine by Daniel Ellsberg at my library.

Is there anything else that talks about what would happen after a nuclear blast from the perspective of a civilian population? Basically I want the nonfiction version of Threads. Accounts of Hiroshima / Nagasaki / Chernobyl are fine too, though again I want to focus less on the government perspective.

Thanks!
