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?

    Assuming your home isn’t on fire. Seal everything, do not go outside! If possible, stay inside for as long as possible. Fill everything with water your bathtub, every cup, bucket, etc. Monitor the radio for emergency broadcasts for what to do next. AM stations are more likely to work. If you have a CB radio handy, (depending on your country) you can talk to authorities on Channel 9.

      There is also amateur radio (aka ham radio), which can legally and practically operate at higher output powers if necessary, and on far more frequencies than CB. Although doomsday people often say to just buy a ham radio and use it without a license, I don’t advise that, simply because having the radio is only half the challenge.

      The other half is the ability to competently operate the radio to effectively communicate and organize aid. And this only comes with practice by talking to others, in the form of regular participation in radio nets and/or emcomm activities. Emergency radio isn’t even limited to voice transmissions, with digital modes and even fax modes being an option that can transmit quicker and farther. Having a legit call sign will make it easier for rescuers to identify your transmissions, as well as figuring out if you’ve been located.

      While some people will make ham radio a lifelong hobby, others obtain their license simply for small-talk, or for a SHTF scenario, or as longer-distance walkie-talkies when camping in heavily wooded forests. The possibilities are endless, but it all starts with a first radio and some basic training on radio handling.

      Ham radio clubs across the USA and the world are generally very welcoming of new folks, so it’s worth looking up your nearby club or dropping in on an in-person club meeting.

    Say there is a nuclear explosion in the downtown of my US city.

    If it’s that close you then essentially you’ll need to decide whether to die quick or slow :/

    If you’re actually planning on surviving you’d need to stay in an underground bunker or something similar for at least 3-5 weeks to be safe enough to travel outside (and we’re assuming you have clean sources of food/water, bathroom, etc, during that time). If you make it that far then afterwards you’d likely want to go outside & get as far away from the radiation zone as possible.

    Coincidentally the basement of my work building actually has a fallout shelter sign from back in the day so the basement might survive a blast but I don’t see how I’d make it 3-5 weeks without being extra prepared for that beforehand.

      It really depends.

      Scale of bomb

      Design of bomb.

      Distance from epicenter

      Ground explosion or atmospheric

      Prevailing winds

      City construction

      Etc, etc.

      It’s nowhere near as simple as we’ve been taught.

      I’ve looked at the bomb simulator linked above, and for me and my city, and where I live, prevailing winds, etc, only the two largest warheads would have direct effect on me, and fallout isn’t a concern for the rest (distance and prevailing winds).

      Now after that, it would surely be a complete shit show. I’d likely have no water (or maybe I would, this suburb isnt tied to the city). Power would certainly be an issue, as would telephone/cell, radio would be problematic for a short while. Food would be a problem, of course.
