Cesium in Pacific likely to flow back to Japan in 20-30 years

TOKYO (Kyodo) -- Radioactive cesium that was released into the ocean in the nuclear accident at the Fukushima Daiichi power plant is likely to flow back to Japan's coast in 20 to 30 years after circulating in the northern Pacific Ocean in a clockwise pattern, researchers said Wednesday.

Researchers at the government's Meteorological Research Institute and the Central Research Institute of Electric Power Industry disclosed the findings at a meeting of the Geochemical Society of Japan, an academic association, in Sapporo.

The researchers estimated that the amount of radioactive cesium-137 that was directly released into the sea came to 3,500 terabecquerels over the period from March to the end of May, while estimating that roughly 10,000 terabecquerels fell into the ocean after it was released into the air.

One terabecquerel equals 1 trillion becquerels. Cesium-137, which has a relatively long half life of about 30 years, can accumulate in the muscles once it is in the body and can cause cancer.

A total of 13,500 terabecquerels of radioactive cesium-137 is slightly more than 10 percent of that of the residual substance left in the northern Pacific after previous nuclear tests, according to the researchers.

The researchers, including chief researcher Michio Aoyama of the Japan Meteorological Agency's research institute, analyzed how the radioactive material dispersed in the sea during the latest accident, using data on radioactive materials detected after the nuclear tests.

According to the analysis, the cesium is expected to first disperse eastward into the northern Pacific from the coast of Fukushima Prefecture, northeast of Tokyo, via relatively shallow waters about 200 meters deep or less.

The cesium will then be carried southwestward from the eastern side of the International Date Line at a depth of 400 meters before some of it returns to the Japanese coast carried northward by the Japan Current from around the Philippines.

The analysis showed that some of the cesium will flow into the Indian Ocean from near the Philippines, and in another 40 years will reach the Atlantic, while some will turn westward south of the equator after reaching the eastern end of the Pacific and crossing the equator.

Tokyo Electric Power Co., the operator of the crisis-hit plant, said about 1,000 terabecquerels of radioactive cesium had leaked into the sea from cracks at the plant.

The researchers' estimate, which was calculated using the density of cesium detected in seawater, is more than triple that.

"To get a complete picture of cesium-137 released in the accident, we need highly precise measurements across the Pacific," Aoyama said before Wednesday's meeting.

More like 50%

:(

Add in the Cs-134, with a 2 year half-life to boost the total cesium in the North Pacific by another 10% for a total of 20%.

Add in the radioactive Iodine, which quite possibly (probably) doubled the radionuclides again.

Then throw in the Plutonium, transuranics and all the rest ...

Fukushima probably boosted the radionuclide stew concentration in the North Pacific by about 50%. This would include industrial dumping, military dumping, Chernobyl and ALL weapons tests ever conducted.

Of course, within a 500 mile radius of Honshu Island, the total is probably more like 75%...

Enjoy the diseased, distressed and mutant seafood ...

Peta-Becquerals

:(

The Japanese people will not have to wait for the slow drift to return the sewage. Peta-Becquerals of radionuclides are suspended in their coastal waters. Additional Peta-Becquerals are deposited on the sea floor, ready to be stirred into action.

Peta-Becquerals of land deposited Fukushima Daiichi radionuclides wash into the sea with each rain shower. Peta-Becquerals are suspended in the Fukushima groundwater; also drifting into the Japanese Coastal waters, in every direction.

PETA ... for when a trillion (Tera) is too small a number ...

PETA-Becquerals working their way into a food chain near you.

Link to MRI and CRI report on cesium circulation in the Pacfiic?

Somebody have a link to the report from the Meteorological Research Institute and the Central Research Institute of Electric Power Industry?

Ah, lovely ... this

Ah, lovely ... this cancer-causing poison now swirling around in the oceans ... and getting into the food chain ... for decades.

Brilliant decision to build these nuclear hell-holes in such earthquake and tsunami prone areas.

Well done Japan........................

:( The Soviet Union lied

:(

The Soviet Union lied about the Chernobyl contamination.

TEPCO, General Electric, Hitachi, Siemens, Areva, ... Japan and the USA have lied about the Fukushima Daiichi contamination.

Perhaps occupational exposure to radionuclides adversely affects the veracity sectors of human grey-matter.

I'd like to get more

I'd like to get more information about expected concentrations on the northwest coast of Canada and the US. Again, this research underlines the need to test our ocean-going Pacific salmon--and not just this year!

Fish biomagnifacation

“Depending on the species, fish have been known to accumulate as much as 100 times the amount of pollutants in the environment,” Jota Kanda, a professor at Tokyo University of Marine Science and Technology specializing in marine environment, said by phone yesterday.

“The scope of testing needs to increase, especially in the neighboring prefectures of Miyagi and Iwate,” Kanda said. “In Chernobyl's case, it took about six months to a year for cesium concentrations in fish to peak.”

“Depending on the species,

“Depending on the species, fish have been known to accumulate as much as 100 times the amount of pollutants in the environment,”

Does it happen, or at least does it happen at the same rate, with Cesium too? Since it's water soluble I think it would be a bit different than Methylmercury for example.
