fukushima is a creeping disaster...,

Spiegel | The technicians had tried for days to restore electricity to the remains of the Fukushima nuclear power plant. But then it was ordinary rubber boots, of all things, that would come to symbolize their desperation, helplessness and defeat.

On Thursday, the three men had made their way into the basement of the turbine building for reactor No. 3 to examine the situation there. When they returned later, they came fully equipped with tools and protective gear that included helmets, masks, rubber gloves and raincoats on top of their radiation suits.

The one thing the men were not prepared for was that suddenly they would be wading through more than a few inches of water. Two of the workers were only wearing ankle-high boots, which allowed the water to seep in. With wet feet, the men spent three-quarters of an hour working on the cables, despite the fact that their dosimeters were beeping for a long time.

The workers are now under observation at the National Institute of Radiological Sciences. The water at Fukushima was so contaminated that radioactive beta radiation burned their skin. In less than an hour, they were exposed to about 180 millisievert of radiation, or nine times as much as one nuclear power plant employee is exposed to in an entire year. "These kinds of burns will be causing problems for the men for a long time to come," says Peter Jacob, director of the Institute for Radiation Protection at the Helmholtz Center in Munich, Germany. Commenting on the exposure, a coworker of the three men said laconically: "We do pay attention. But now we have to be even more careful as we work."

The incident revealed, once again, how little experts know about the dangers that still lurk on the grounds of the ill-fated plant. No one had expected the radiation level in the water in the basement to be as high as it was. The levels of radiation in water in the basement of reactors No. 1, No. 2 and No. 3 reached record highs, with water at No. 2 measuring 1,000 millisieverts per hour. This was due to a partial core melt. Also, the containment vessel for the third reactor was apparently damaged, representatives of the Japanese nuclear regulatory agency concluded. Could this mean that there is a crack in the barrier between the highly radioactive core and the surrounding environment?

The beginning of last week offered grounds for cautious optimism. Power had been restored to the damaged reactor No. 1, a German concrete mixer was pumping water into the dangerously empty pool containing spent fuel rods in Unit 4, and there had been no explosions in the plant for an entire week. Two weeks after the disaster in Fukushima began, all of this sounded like good news.

'An Ongoing, Massive Release of Radioactivity'
Meanwhile, however, the engineers have been forced to realize that they have made almost no headway in restoring the cooling system. By Friday night, pumps were still not working in any of the damaged reactors. Up to 45 tons of sea salt have apparently accumulated in the containment vessels, complicating the cooling effort. The salt is crystallizing in warm spots and creating an unwanted layer of insulation. The engineers planned to start flushing fresh water into the reactors on Friday afternoon. But the reactors are only one problem. There's also the issue of the 3,450 spent fuel rods, which are red-hot, presumably severely damaged and exposed to the air in half-empty pools.

"We are experiencing an ongoing, massive release of radioactivity," says Wolfram König, head of Germany's Federal Office for Radiation Protection. "And everyone should know by now that this isn't over by a long shot." Nuclear expert Helmut Hirsch says: "All I hear is that people are wondering whether this will turn into a meltdown. But the thing is, it already is a partial meltdown." The difference, in this case, is that Fukushima is a creeping disaster.

Forty-four percent of all Americans said that recent natural disasters could be a sign of the Biblical end times, with 67 percent of white evangelicals holding that view. (In comparison, 58 percent of Americans attributed recent severe natural disasters to global climate change, as did 52 percent of evangelicals.)
"If you believe God ultimately is in charge of everything but doesn't control the minutiae of daily life, then I think it's easier to reconcile," Foy said. "God would still care, but did not cause the tsunami to punish people."

Don't know what g_d got to do with it, but it sure shows the power of meme
