I was able to drill through the crap to get us that link.
I recommend you go to the image link and battle it out for yourself, since the assurances of radiation levels being well below what the EPA deems alarming has always been highly suspect, and is about to reach critical mass.
By measuring the energy of the gamma rays from the filters, [people at University of Washington] have identified exactly which fission products have made their way across the Pacific. And this in turn allows them to make a number of interesting inferences about what has gone wrong at Fukushima. Today, they post the results of the first five days of monitoring on the arXiv.
What they found was small amounts of iodine-131, iodine-132, tellurium-132, iodine-133, cesium-134 and cesium 137.
The first comes from the amount of iodine-131 and tellurium-132 which are both short-lived with half lives of 8 and 3 days respectively. That indicates that they must have come from fuel rods that were recently active rather than from spent fuel.
[T]hese guys speculate that what they're seeing is the result of contaminated steam being released into the atmosphere.
At length, we have come to the point where there is some indication of the claptrap Secretary Chu was on about at least a week ago, and seemed psychedelic at the time. This might mean No. 2, the unit that appears, from the outside, to be in the best shape, had already melted down when he was talking about it and we just didn't get to hear about it for all these days, OR, and you MUST consider this, it's an attempt at misdirection, a bid to get us to take our eyes off their sacred MOX in No. 3, which is now so mangled that it no longer resembles a former building.
