A/C, you should go yell at whoever put together that map. The figures there include deaths from car crashes, tuberculosis, and lung cancer, not just radiation-related deaths. Terrible garbage science like this is a setback to the state of rational discourse. Yes, I'm actually offended by that graphic.
I've got a link to the live radiation data that The Man is trying to keep quiet:
Monitoring Results from Portland, OR | RadNet | US EPA
I've studied humans long enough to know that the urge to dig a bunker comes first, and information about radiation comes afterward. I can show you that the data doesn't support your conclusion, but I really can't change your mind about the bunker. Well, at least we can exchange tips about where and how to build efficient outbuildings, and how to plant a garden that will keep you well fed throughout the year.
