For the first time, seaborne radiation from Japan’s Fukushima nuclear disaster has been detected on the West Coast of the United States. Cesium-134, the so-called fingerprint of Fukushima, was measured in seawater samples taken from Tillamook Bay and Gold Beach in Oregon, researchers from the Woods Hole Oceanographic Institution are reporting. Because of its short half-life, cesium-134 can only have come from Fukushima.

Also for the first time, cesium-134 has been detected in a Canadian salmon, the Fukushima InFORM project, led by University of Victoria chemical oceanographer Jay Cullen, is reporting.
Massive amounts of contaminated water were released from the crippled nuclear plant following a 9.0 magnitude earthquake and tsunami in March 2011. More radiation was released to the air, then fell to the sea.
Woods Hole chemical oceanographer Ken Buesseler runs a crowd-funded, citizen science seawater sampling project that has tracked the radiation plume as it slowly makes its way across the Pacific Ocean.
The Oregon samples, marking the first time cesium-134 has been detected on U.S. shores, were taken in January and February of 2016 and later analyzed. They each measured 0.3 becquerels per cubic meter of cesium-134.
Buesseler’s team previously had found the isotope in a sample of seawater taken from a dock on Vancouver Island, B.C., marking its landfall in North America.
Meanwhile, in Canada, Cullen leads the InFORM project to assess radiological risks to that country’s oceans following the nuclear disaster. It is a partnership of a dozen academic, government and non-profit organizations, including Woods Hole.
Last month, the group reported that a single sockeye salmon, sampled from Okanagan Lake in the summer of 2015, had tested positive for cesium-134.
The level was more than 1,000 times lower than the action level set by Health Canada, and is no significant risk to consumers, Cullen said.
Buesseler’s most recent samples off the West Coast also are showing higher-than background levels of cesium-137, another Fukushima isotope that already is present in the world’s oceans because of nuclear testing in the 1950s and 1960s.
New reading taken from Reactor 2 at Fukushima reveals a global problem with “unimaginably high” radiation levels
Radiation at Fukushima’s nuclear power plant is reportedly at its highest level since the event nearly six years ago. It is being said that it will take 40 years to decommission the plant, but even that estimate may be too optimistic.
Tepco (Tokyo Electric Power Company) and its network of partner companies at Fukushima Daiichi have yet to identify the location and condition of melted fuel in the three most seriously damaged reactors.
Professor Christopher Busby from the European Committee on Radiation Risks, gave RT his insight into the recent developments in Japan:
“Of course, it’s time for the Japanese government to take control. But having said that, it’s very hard to know how you could take control of the situation. The situation is essentially out of control,” Busby said.
“I believe personally that it’s a global problem – and not the Japanese government’s problem only.”
It has been reported that TEPCO found an area with higher levels of radiation than they had seen before. To do this, they used a 10.5-meter-long (34.4-foot-long) telescopic arm, examining an area inside reactor 2 called the “pedestal”.
A camera attached to the arm revealed what looks like a grating that had been melted by exposed fuel from one of the reactors. The images show a square hole measuring 1 meter (3.3 feet) on each side, believed to have originated from melted fuel rods from a pressure vessel above.
Earlier this week, the utility released images of dark lumps found beneath reactor No. 2 that it believes could be melted uranium fuel rods – the first such discovery since the disaster. If confirmed, this would be the first melted fuel found from the reactor – an important step towards decommissioning the plant itself.
“Nuclear fuel in the Primary Containment Vessel (PCV) was exposed to the air and melted from the impact of [the] March 2011 Great Earthquake,” TEPCO noted in a media handout.
“As a result of the accident analysis, it was found that a portion of melted nuclear fuel might have been fallen [sic] inside the pedestal.”
The facility’s operator, Tepco, said atmospheric readings as high as 530 sieverts an hour had been recorded inside the containment vessel of reactor No 2, one of three reactors that experienced a meltdown when the plant was crippled in 2011.
The recent reading, described by some experts as “unimaginable”, is far higher than the previous record of 73 sieverts an hour in that part of the reactor.
A single dose of one sievert is enough to cause radiation sickness and nausea; 5 sieverts would kill half those exposed to it within a month, and a single dose of 10 sieverts would prove fatal within weeks.
It is indisputable that there is a daily flow of radioactively-contaminated groundwater into the ocean. The flow is approximately 80,000 gallons per day of relatively low-level radioactive waste water. The storage tanks contain 800,000 tons of highly radioactive water. Every day they pour a hundred tons of water on each of these three melted-down cores. Sometimes they lose those tanks. They leak, they overflow – it is an ongoing catastrophe.
Quantities of melted fuel are believed to have accumulated at the bottom of the damaged reactors’ containment vessels, but dangerously high radiation has prevented engineers from accurately gauging the state of the fuel deposits.
State-of-the-art robotic technology, of which Japan is a leader, can only last so long because the electronics get fried by the gamma radiation and, possibly, the neutron radiation inside. Perhaps future technological developments and robotics can help.
In order to decommission Fukushima, engineers first need to find the melted fuel. TEPCO still don’t know where the cores are. Removing it safely represents a challenge unprecedented in the history of nuclear power.
Once the fuel has been found, it’s thought it will take four decades to completely decommission Fukushima. The total cost of the project is expected to cost an eye-watering 21.5 trillion yen ($188 billion), which is almost double an estimate in 2013.
The official story says that the meltdown at Fukushima was caused when a 9.0-magnitude earthquake off the northeast coast of Japan triggered a tsunami on March 11, 2011. More than 18,500 people were killed, and the backup power supply at Fukushima was destroyed, causing three of its six reactors to fail. About 160,000 people had to be evacuated as a result, with little prospect of ever returning.
Nevertheless, multiple independent journalists suggest the original disaster was a terrorist attack launched against Japan by the New World Order and Israel as a payback because Japan backed the Palestinian right at the UN and also offered to enrich Uranium for Iran in 2010. This version of the events suggests that the NSA/Israel Virus “Stuxnet” was planted at Fukushima together with few mini-nukes and another nuke / HAARP caused the tsunami to cover up the inland explosions and give the impression everything had natural causes.
As Tokyo plans to host the 2020 Olympics which will bring in many millions of extra people into this already densely populated area, TEPCO and the Japanese government must be hoping nothing goes wrong with the radioactive waste storage pools. They could still potentially go up in flames. This would then necessitate the evacuation of all of Northeast Japan – up to 50 million people.
