UPDATE: I'm cleaning house... Previously I had the full context of a great article by Shane Conner of ki4u.com posted on here. I was happy to share it and still recommend you read it. However, due to the length and amount of graphics included in the article I have trimmed it down to just an introduction to the article followed by a link to the actual article itself...
This guide 'When An ill Wind Blows From Afar! (Like from Japan Fukushima reactor)' deals specifically with radioactive fallout that originated from afar, like a Chernobyl in the past,
or Iran in the future that's had its nuclear facilities bombed, releasing radioactive contamination into the atmosphere, or a North Korea gone mad, etc.
This guide provides panic dispelling knowledge so people downwind can more promptly initiate appropriate protective actions, as required.
This is the third in the series that begins with The Good News About Nuclear Destruction! at www.ki4u.com/goodnews.htm
that debunks the myths of nuclear un-survivability and What To Do If A Nuclear Disaster Is Imminent! at www.ki4u.com/guide.htm
that details the practical methods for American families to protect themselves from nuclear explosion(s) and fallout originating here.
You can read the full article here.
I do reccommend going to the site even if you're not in a current "danger zone" because education and knowledge are good to have. Especially in a situation that can be life threatening. My prayer is that you will seek the guidance of the Lord in these matters and learn without undue fear. Fear of the Lord is the only fear we should carry, all else is just fluff.
14"Now therefore fear the LORD, and serve him in sincerity and in truth: and put away the gods which your fathers served on the other side of the flood, and in Egypt; and serve ye the LORD." Joshua 24:14 KJV
