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?
The frustrating thing is that masks don’t protect you particularly well. What they do is protect others from any infection you are carrying. This is why it was more important to provide them to those interacting with infected or vulnerable people. It limited the risk of spreading it further.
