Oceanus Magazine has done a very interesting series on the Fukushima disaster. Written in May 2013, the information is obtained from the marine scientists at Woods Hole and elsewhere--highly trained people who have first-hand knowledge of what's actually going on, as opposed to the many nonsensical, fear-mongering articles currently circulating on the Net. The information is both distressing and reassuring, as one might expect. There are enough links and sections to keep a true Fukushima junkie occupied for hours.
