They’ve talked about it so much I actually looked up what you should do in case of a nuclear attack b/c lord knows I can’t remember what they told me in 2nd grade. Of course the closer you are to it the worse it will be- but you need to stay in your basement (cement walls) and cover the windows with cardboard at least- even mattresses and live there at least 2 weeks. Also depending on how far the nuclear ash would fall - you should immediately place tarps on your lawn so nuclear ash doesn’t sink in so you have somewhere to try & grow food later on. Also there are potassium chloride (?) tablets you should take (Amazon sells them) & hopefully have some clean water stored. If you do go outside you’ll have to strip down your clothes (before going back in) & shower to lessen the exposure. Just some tips that stuck with me!
