For the purposes of discussion in the Japan Disaster threads, I’ve made a graphic that very roughly approximates the zone of likely future very high rates of cancer if the Fukushima nuclear power plant were located where our (somewhat similar but smaller) plant is located, upwind during the winter of the Twin Cities. The lightened up area (circular) would be the zone in which agriculture would probably cease. Anyone who knows this area knows that the main outputs are electricity and produce!
This is not meant to represent what would happen here … different plants, different conditions, etc. The idea is just to make it easier for people from the area to understand the scale of space we are talking about here.
