Disaster Ratings

Chernobyl and Fukushima now have the same rating for nuclear disasters. Seven is the highest disaster rating and is correct for Fukushima, based of the state of the plant. However, as this Wired article points out, there is order of magnitude difference between Chernobyl and Fukishima. It is an excellent example of how a simple rating system "dumbs down" a complex problem to the point where it is meaningless to the people the system was meant to inform.
