Japan is to invest hundreds of millions of dollars into building a frozen wall around the Fukushima nuclear plant to stop leaks of radioactive water.

Government spokesman Yoshihide Suga said an estimated 47bn yen ($473m, £304m) would be allocated.

The leaks were getting worse and the government “felt it was essential to become involved to the greatest extent possible”, Mr Suga said.

Way too late, government.



Now TEPCO is lining its radioactive waste pools with quilts

The biggest scare at the plant in recent days has been the discovery that at least three of seven underground storage pools are seeping thousands of gallons of radioactive water into the soil. On Wednesday, Tepco acknowledged that the lack of adequate storage space for contaminated water had become a “crisis,” and said it would begin emptying the pools. But the company said that the leaks will continue over the several weeks that it will likely take to transfer the water to other containers.

Plant workers dug these underground ponds about six months ago to store the ever-growing amount of contaminated water at the plant. There is about 400 tons daily from two sources: runoff from a makeshift cooling system rigged together after the site’s regular cooling equipment was knocked out by the earthquake and tsunami in March 2011, and a steady stream of groundwater seeping into damaged reactors.

Tepco stores more than a quarter-million tons of radioactive water at the site and says the amount could double within three years.

But as outside experts have discovered with horror, the company had lined the pits for the underground pools with only two layers of plastic each 1.5 millimeters thick, and a third, clay-based layer just 6.5 millimeters thick. And because the pools require many sheets hemmed together, leaks could be springing at the seams, Tepco has said.

“No wonder the water is leaking,” said Hideo Komine, a professor in civil engineering at Ibaraki University, just south of Fukushima. He said that the outer protective lining should have been hundreds of times thicker.

Remember when we thought Japan was leading the world into a utopia of capitalist industrial perfection?



American babies and Fukushima

Mangano and Sherman, “Elevated airborne beta levels in Pacific/West Coast US States and trends in hypothyroidism among newborns after the Fukushima nuclear meltdown” Open Journal of Pediatrics, Volume 3, Number 1, March 2013.

1.2. Exposure to Radioactive Iodine as a Factor
in Congenital Hypothyroidism

Another potential environmental risk factor is prenatal
exposure to radioactive iodine isotopes, which seek out
the susceptible fetal thyroid gland. For decades radioactive
iodine has been recognized to cause adverse effects
(including hypothyroidism) to the thyroid gland. The
fetal thyroid, the first glandular structure to appear in the
human embryo [14], begins to concentrate iodine and
produce thyroid hormones by the 70th day of gestation
[15]. In the mid-1950s, during the period of atmospheric
nuclear weapons tests, I-131 produced by fission was
first detected in the adult human thyroid [16,17]. I-131
concentrations were calculated to be about 10 times
higher in the human fetal thyroid vs. the human adult or
hog thyroid [18], and maximum elevations in fetal thy-
roids were detected approximately one month after nuclear
explosions [19]. The main path of exposure to shortlived
isotopes such as I-131 is via dairy products due to
radioactive fallout deposition on forage [20].

It gets all over the grass, the cows eat the grass, and the I-131 and Cesium are thus concentrated in cheese and milk.

…Large amounts of fallout disseminated worldwide from the meltdowns in four reactors at the Fukushima-Dai-ichi plant in Japan beginning March 11, 2011 included radioiodine isotopes. Just days after the meltdowns, I-131 concentrations in US precipitation was measured up to 211 times above normal. Highest levels of I-131 and airborne gross beta were documented in the five US States on the Pacific Ocean. The number of congenital hypothyroid cases in these five states from March 17-December 31, 2011 was 16% greater than for the same period in 2010, compared to a 3% decline in 36 other US States (p < 0.03). The greatest divergence in these two groups (+28%) occurred in the period March 17-June 30 (p < 0.04). …

Radioactive bluefin tuna crossed the Pacific to US

Five months after the Fukushima disaster, Fisher of Stony Brook University in New York and a team decided to test Pacific bluefin that were caught off the coast of San Diego. To their surprise, tissue samples from all 15 tuna captured contained levels of two radioactive substances—ceisum-134 and cesium-137—that were higher than in previous catches.

[...]

The results “are unequivocal. Fukushima was the source,” said Ken Buesseler of the Woods Hole Oceanographic Institution, who had no role in the research.

Bluefin tuna absorbed radioactive cesium from swimming in contaminated waters and feeding on contaminated prey such as krill and squid, the scientists said. As the predators made the journey east, they shed some of the radiation through metabolism and as they grew larger. Even so, they weren’t able to completely flush out all the contamination from their system.

“That’s a big ocean. To swim across it and still retain these radionuclides is pretty amazing,” Fisher said.

All well below “safe levels,” of course, according to govt. agencies. That’s fine, I won’t be eating any. More for you!



Radionuclide contamination in Fukushima and adjacent prefectures

The outside annual radiation dose due to the radionuclides from the Fukushima accident is estimated to be 10 mSv in Naka-Dori, 40 mSv in Iitate, 0.2 mSv in the region between northern Ibaraki and eastern Saitama, and 2 mSv in southern Ibaraki and northern Chiba prefectures (note that the present estimate does not include the doses from short-lived radionuclides). No internal dose contribution is assumed in these estimations.
