I recently saw a comment chain about nuclear bombs, and that led me to thinking about this. Say there is a nuclear explosion in the downtown of my US city. I survive relatively fine, but obviously the main part of the city has been destroyed, while major zones extending from the center were also badly damaged. What would be a good response to (a) survive and (b) help out the recovery effort?
How long would I have to stay indoors? A week? A month?
Generally, the worst intensity stuff is actually over in the first 48-72 hours depending upon various factors. That’s not to say outside is completely safe after that (it wouldn’t be), but the level of danger is very different.
As long as possible to an indeterminate time and/or when authorities indicate to leave.
