Yet looking at this site http://www.radiationnetwork.com/ it seems to be down wind from that TN cluster and actually in the middle of quite
a cluster from other states..I didn`t realise they were so many of those things on the east coast.
Yup...there's no escaping them in the Eastern US. and the Western states are already too cold to grow much, plus they've got multiple volcanoes that could blow without much warning, and are actually a worse, long term threat than a reactor.
I tried to put as much distance between us and an active reactor as possible, so we have time to get down into a cave if one blows. Some of the sites on the map you referenced are actually storage sites for spent fuel rods, which aren't as dangerous (from a distance) as an active reactor, but still represent a radiation threat if damaged by a natural disaster.
The disaster in Japan has brought up a lot of fears about nuclear reactors, especially among survivors of the Three Mile Island melt down and the Surry explosion. Risk assessment when a reactor starts to vent radiation is VERY difficult, because the level of risk outside the immediate danger zone is largely dependent on the weather and prevailing winds.
At least now we have MUCH better tools at our disposal for sharing information and predicting the path of a plume. When TMI blew, we only had CB's and a few BBS's, and they were up and down like yoyos because the phone system was overloaded. Government official lied through their teeth (of course) and the ensuing panic caused 100's of thousands of people who were fairly safe where they were to evacuate...directly into the path of the plume. People were hosing refugees down, making them strip to the skin and leave everything they'd brought with them in a big pile ...it was a mess.
A few years later, when Surry had a huge explosion that rocked the whole county, NO ONE believed the government when they said the reactors weren't compromised...and it was actually the truth that time.
What I learned from living through these events is that when a radiation cloud takes to the wind, the only things you can do are get out of its path, or go underground. This latest disaster has also convinced me that I need to replace my 25 year old Geiger counter
