========== [♪ INTRO] Let’s start by saying the odds of a nuclear
bomb hitting anywhere near you is very unlikely. But if you’re the type of person
who always wants to be prepared, it might help to know a little bit about
how explosions and radioactivity work. So, even though you probably won’t need
to be hunkering down anytime in the near future, here’s a science-based guide to how to ride
out a nuclear attack. A nuclear detonation releases
a massive amount of energy. And depending on the size of the bomb and how
high it is in the atmosphere when it goes off, that energy can affect you even if you’re
tens of kilometers from the detonation site. The size of nuclear bombs is
measured by kilotons, or how many thousands of tons of TNT you’d have to
blow up to re...
