Most of the Quora discussion seems reasonable for the safest locations. But it is a pretty big sacrifice to change countries just because of the threat of nuclear war. So I am looking at lower cost options. Also, being outside the target countries even in the northern hemisphere would generally not be too bad because the radiation largely rains out within a few days. And even within the target countries if you are not hit by the blast/​fire, you’re most likely to survive. I believe the radiation exposure would be lower than Chernobyl, which took about one year of life off the people nearby.
