Radioactive Water From Fukushima Is Systematically Poisoning The Entire Pacific Ocean





Right now, a massive amount of highly radioactive water is escaping into the Pacific Ocean from the ruins of the destroyed Fukushima nuclear facility in Japan. This has been going on all day, every day for more than two years. The enormous amounts of tritium, cesium and strontium that are being released are being carried by wind, rain and ocean currents all over the northern Hemisphere. And of course the west coast of the United States is being hit particularly hard. When you drink water or eat seafood that has been contaminated with these radioactive particles, they can stick around for a very long time. Over the coming years, this ongoing disaster could potentially affect the health of millions upon millions of people living in the northern hemisphere, and the sad thing is that a lot of those people will never even know the true cause of their health problems.

For a long time, the Japanese government has been trusting Tepco to handle this crisis, but now it has become abundantly clear that Tepco has no idea what they are doing. In fact, the flow of radioactive water has gotten so bad that authorities in Japan are now calling it an “emergency”…


Highly radioactive water seeping into the ocean from Japan’s crippled Fukushima nuclear plant is creating an “emergency” that the operator is struggling to contain, an official from the country’s nuclear watchdog said on Monday.

This contaminated groundwater has breached an underground barrier, is rising toward the surface and is exceeding legal limits of radioactive discharge, Shinji Kinjo, head of a Nuclear Regulatory Authority (NRA) task force, told Reuters.

The amount of water that we are talking about is absolutely enormous. According to Yahoo, 400 metric tons of water is being pumped into the basements of destroyed buildings at Fukushima every single day…

The utility pumps out some 400 metric tons a day of groundwater flowing from the hills above the Fukushima Daiichi nuclear plant into the basements of the destroyed buildings, which mixes with highly irradiated water that is used to cool the reactors in a stable state below 100 degrees Celsius.

Tepco is trying to prevent groundwater from reaching the plant by building a “bypass” but recent spikes of radioactive elements in sea water has prompted the utility to reverse months of denials and finally admit that tainted water is reaching the sea.
And of course all of that water has to go somewhere. For a long time Tepco tried to deny that it was getting into the ocean, but now they are finally admitting that it is…


Tepco said on Friday that a cumulative 20 trillion to 40 trillion becquerels of radioactive tritium had probably leaked into the sea since the disaster. The company said this was within legal limits.

Tritium is far less harmful than cesium and strontium, which have also been released from the plant. Tepco is scheduled to test strontium levels next.
40 trillion becquerels of radioactive tritium have gotten into the Pacific Ocean?

And that is what they are publicly admitting. The reality is probably far worse.

And all of that tritium is going to be around for a very long time. You see, the truth is that tritium has a half-life of about 12 years.

But strontium is even worse. Strontium can cause bone cancer and it has a half-life of close to 29 years.

And now Tepco is admitting that extremely dangerous levels of strontium have been escaping from Fukushima and getting into the underground water. And of course the underground water flows out into the Pacific Ocean…

Tepco said in late June that it had detected the highly toxic strontium-90, a by-product of nuclear fission that can cause bone cancer if ingested, at levels 30 times the permitted rate.

The substances, which were released by the meltdowns of reactors at the plant in the aftermath of the huge tsunami of March 2011, were not absorbed by soil and have made their way into underground water.

Subsoil water usually flows out to sea, meaning these two substances could normally make their way into the ocean, possibly affecting marine life and ultimately impacting humans who eat sea creatures.

Cesium has an even longer half-life than strontium does. It has a half life of about 30 years, and according to samples that were taken about a month ago levels of cesium at Fukushima have been spiking dramatically…

Samples taken on Monday showed levels of possibly cancer-causing caesium-134 were more than 90 times higher than they were on Friday, at 9000 becquerels per litre, Tokyo Electric Power (Tepco) revealed.

Levels of caesium-137 stood at 18 000 becquerels per litre, 86 times higher than at the end of last week, the utility said.

“We still don’t know why the level of radiation surged, but we are continuing efforts to avert further expansion of contamination,” a Tepco spokesperson stated.
When cesium gets into your body, it can do a tremendous amount of damage. The following is an excerpt from a NewScientist article that described what happens when cesium and iodine enter the human body…

Moreover the human body absorbs iodine and caesium readily. “Essentially all the iodine or caesium inhaled or swallowed crosses into the blood,” says Keith Baverstock, former head of radiation protection for the World Health Organization’s European office, who has studied Chernobyl’s health effects.

Iodine is rapidly absorbed by the thyroid, and leaves only as it decays radioactively, with a half-life of eight days. Caesium is absorbed by muscles, where its half-life of 30 years means that it remains until it is excreted by the body. It takes between 10 and 100 days to excrete half of what has been consumed.
And it is important to keep in mind that it has been estimated that each spent fuel pool at the Fukushima nuclear complex could have 24,000 times the amount of cesium that was produced by the nuclear bomb that the U.S. dropped on Hiroshima at the end of World War 2.

Overall, the Fukushima nuclear facility originally contained a whopping 1760 tons of nuclear material.

That is a massive amount of nuclear material. Chernobyl only contained 180 tons.

And of course the crisis at Fukushima could be made even worse at any moment by a major earthquake. In fact, a magnitude 6.0 earthquake hit northern Japan on Sunday.

This is a nightmare that has no end. Every single day, massive amounts of highly radioactive water from Fukushima is systematically poisoning the entire Pacific Ocean. The damage that is being done is absolutely incalculable.

If people are worried now, they should have been worried for the last 50 years. Read the bold.

Here is what you need to know about the radioactive water leaking from Japan’s Fukushima nuclear plant into the Pacific Ocean.

Scientists on both sides of the Pacific have measured changing levels of radioactivity in fish and other ocean life since the March 2011 earthquake and tsunami triggered a nuclear meltdown at Japan’s Fukushima Daiichi nuclear plant. On Aug. 2, 2013, when Japan’s Tokyo Electric Power Co. (TEPCO) gave its first estimate of how much radioactive water from the nuclear plant has flowed into the ocean since the disaster, the company was finally facing up to what scientists have recognized for years.

"As an oceanographer looking at the reactor, we've known this since 2011," said Ken Buesseler, a marine chemist at the Woods Hole Oceanographic Institute in Woods Hole, Mass. "The news is TEPCO is finally admitting this."

TEPCO estimated that between 20 trillion and 40 trillion becquerels (units of radioactivity representing decay per second) of radioactive tritium have leaked into the ocean since the disaster, according to the Japanese newspaper Asahi Shimbun. The Fukushima plant is still leaking about 300 tons of radioactive water into the ocean every day, according to Japanese government officials. [Infographic: Inside Japan's Nuclear Reactors]

Japan is haunted by two lingering questions from this aftermath of the disaster: First, how the radioactivity might seriously contaminate ocean life that represents a source of seafood for humans; second, whether it can stop the leaks of radioactive water from the Fukushima plant.

Radioactivity is not created equal

The Fukushima plant is leaking much less contaminated water today compared with the immediate aftermath of the nuclear meltdown in June 2011 — a period when scientists measured 5,000 to 15,000 trillion becquerels of radioactive substances reaching the ocean. Even if radioactivity levels in the groundwater have spiked recently, as reported by Japanese news sources, Buesseler expects the overall amount to remain lower than during the June 2011 period.

"The amount of increase is still much smaller today than it was in 2011," Buesseler told LiveScience. "I'm not as concerned about the immediate health threat of human exposure, but I am worried about contamination of marine life in the long run."

The biggest threat in the contaminated water that flowed directly from Fukushima's reactors into the sea in June 2011 was huge quantities of the radionuclide called cesium. But the danger has changed over time as groundwater became the main source for leaks into the ocean. Soil can naturally absorb the cesium in groundwater, but other radionuclides, such as strontium and tritium, flow more freely through the soil into the ocean. (TEPCO is still coming up with estimates for how much strontium has reached the ocean.)

Tritium represents the lowest radioactive threat to ocean life and humans compared with cesium and strontium. Cesium’s radioactive energy is greater than tritium, but both it and tritium flow in and out of human and fish bodies relatively quickly. By comparison, strontium poses a greater danger because it replaces the calcium in bones and stays for much longer in the body.

Not fishing for trouble

A number of fish species caught off the coast of the Fukushima Prefecture in 2011 and 2012 had levels of cesium contamination greater than Japan's regulatory limit for seafood (100 becquerels per kilogram), but both U.S. and Japanese scientists have also reported a significant drop in overall cesium contamination of ocean life since the fall of 2011. The biggest contamination risks came from bottom-dwelling fish near the Fukushima site. [In Photos: Fukushima Butterflies Plagued With Defects]

The radioactive groundwater leaks could still become worse in the future if TEPCO does not contain the problem, U.S. scientists say. But they cautioned against drawing firm conclusions about the latest impacts on ocean life until new peer-reviewed studies come out.

"For fish that are harvested 100 miles [160 kilometers] out to sea, I doubt it’d be a problem," said Nicholas Fisher, a marine biologist at Stony Brook University in Stony Brook, N.Y. "But in the region, yes, it's possible there could be sufficient contamination of local seafood so it'd be unwise to eat that seafood."

The overall contamination of ocean life by the Fukushima meltdown still remains very low compared with the effects of naturally occurring radioactivity and leftover contamination from U.S. and Soviet nuclear weapons testing in the 1960s. Fisher said he’d be "shocked" if the ongoing leaks of contaminated water had a significant impact on the ocean ecosystems.

Source of radioactive water

TEPCO is facing two huge issues in stopping the radioactive water leaks. First, groundwater from nearby mountains is becoming contaminated as it flows through the flooded basements of the Fukushima plant's reactor buildings. The water empties into the nuclear plant's man-made harbor at a rate of about 400 tons per day — and TEPCO has struggled to keep the water from leaking beyond existing barriers into the ocean.

"This water issue is going to be their biggest challenge for a long time," said Dale Klein, former head of the U.S. Nuclear Regulatory Commission. "It was a challenge for the U.S. during Three Mile Island [a partial nuclear meltdown in Pennsylvania on March 28, 1979], and this one is much more challenging."

Second, TEPCO must also deal with contaminated water from underground tunnels and pits that hold cables and pipes for the Fukushima nuclear plant’s emergency systems. The underground areas became flooded with highly radioactive water during the initial meltdown of the Fukushima plant’s reactors, and have since leaked water into the ocean despite TEPCO’s efforts to seal off the tunnels and pits.

TEPCO has also been racing to deal with the problem of storing hundreds of thousands of tons of radioactive water from the Fukushima plant, said Hiroaki Koide, a nuclear engineer at Kyoto University in Japan. The Japanese utility is testing a water decontamination system called ALPS that can remove almost all radioactive substances except for tritium, but has put much of the contaminated water in storage tanks in the meantime.

"The tanks are an emergency solution that is not suitable for long-time storage," Koide said. "Water will leak from any tank, and if that happens, it will merge with the groundwater."

What must be done

So what solutions exist beyond building more storage tanks? Klein reviewed a number of possible solutions with TEPCO when he was picked to head an independent advisory committee investigating the Fukushima nuclear accident.

One possible solution involves using refrigerants to freeze the ground around the Fukushima plant and create a barrier that stops the inflow of groundwater from the mountains. TEPCO is also considering a plan to inject a gel-like material into the ground that hardens into an artificial barrier similar to concrete, so that it can stop the contaminated groundwater from flowing into the ocean.

Such barriers could help hold the line while TEPCO pumped out the water, treated it with purification systems such as ALPS, and then figured out how to finally dispose of the decontaminated water.

"My priority would be stop the leak from the tunnel immediately," Klein said. "Number two would be to come up with a plan to stop the inflow and infiltration of groundwater. Number three is to come up with an integrated systematic water treatment plan."

Meanwhile, both Japanese and U.S. scientists continue to gather fresh scientific data on how the radioactivity impacts ocean life. Despite low contamination levels overall, studies have shown great differences in certain species depending on where they live and feed in the ocean.

"The most straightforward thing the Japanese can do now is measure the radionuclides in fish tissue, both at the bottom of the ocean and up in the water column at different distances from the release of contaminated groundwater," Fisher said.
