Newsweek, Oct 4, 2017 (emphasis added): Radiation From Fukushima Nuclear Disaster Discovered in Sand and Groundwater 60 Miles Away… the beach groundwater is even 10 times more radioactive than the ocean directly next to the Fukushima plant.

Gizmodo, Oct 4, 2017: Fukushima’s Radioactive Waste Is Leaking From an Unexpected Source — A new and unexpected source of radioactive material left over from the 2011 Fukushima nuclear disaster has been found up to 60 miles away along coastlines… The discovery shows that damaged nuclear reactors are capable of spreading radiation far from the meltdown site, and in some surprising ways.

UPI, Oct 3, 2017: Beaches found releasing radioactive cesium into ocean 60 miles from Fukushima… Scientists have discovered a surprising new source of radioactive cesium… [Researchers] found unusually high levels of radioactive cesium-137 in the groundwater beneath several beaches… “No one expected that the highest levels of cesium in ocean water today would be found not in the harbor of the Fukushima Dai-ichi nuclear power plant, but in the groundwater many miles away below the beach sands,” WHO researcher Virginie Sanial said…

Fox News, Oct 3, 2017: Fukushima’s radioactive cesium found an unexpected hiding spot… The find wasn’t just a surprise, but significant. As the researchers write, “Aside from the aquifer beneath [the plant], the highest recorded present-day activities of [cesium-137] in the aqueous environment in Japan are associated with brackish groundwater underneath beaches.”

IFL Science, Oct 2, 2017: Scientists investigating the Fukushima Daiichi nuclear power plant in Japan have found an unexpected source of radioactive material… [It’s] an alarming example of how radiation from the reactor has spread… “It is as if the sands acted as a ‘sponge’ that was contaminated in 2011 and is only slowly being depleted,” said study co-author Ken Buesseler…

Study – Unexpected source of Fukushima-derived radiocesium to the coastal ocean of Japan, Sep 26, 2017: [T]he highest radiocesium (137Cs) activities outside of the power plant site were observed in brackish groundwater underneath sand beaches… During our study period, we found the highest cesium-137 (137Cs) levels (up to 23,000 Bq⋅m−3) outside of the FDNPP site not in the ocean, rivers, or potable groundwater, but in groundwater beneath sand beaches over tens of kilometers away from the FDNPP. Here, we present evidence of a previously unknown, ongoing source of Fukushima-derived 137Cs to the coastal ocean… This estimated ocean 137Cs source (0.6 TBq⋅y−1) is of similar magnitude as the ongoing releases of 137Cs from the FDNPP site for 2013–2016, as well as the input of Fukushima-derived dissolved 137Cs via rivers… This unexpected and ongoing 137Cs source requires further investigation…

KTUU, Feb 14, 2017 (emphasis added): Following last year’s massive die-off of Alaskan seabirds, scientists still looking for answers… “Geographically and that it lasted a year, that’s unprecedented, [Kathy Kuletz, a biologist with US Fish & Wildlife Service]… “it’s certainly well over a hundred thousand and it could go many times that.”… “I would say possibly hundreds of thousands were killed… Almost always it’s been starvation… Sea birds are top predators,” [Heather Renner, biologist with Alaska Maritime National Wildlife Refuge] said. “They’re sort of sentinels for our environment. They have definitely let us know that there’s change going on in the ocean ecosystem”… Renner says [the birds had an] exceptionally low birthing season… This reproductive die-off meant a “total failure” of murre reproduction that year… “The reproductive die off is something we’ve never seen in murres before, widespread. The refuge (AMNWR) has been monitoring these colonies for 4 decades and it’s like nothing we’ve ever observed before,” Renner said…

AP, Feb 10, 2017: [T]ens of thousands of common murres… starved and washed ashore on beaches from California to Alaska… “it’s because there’s no fish out there, anywhere, over a very large area,” [John Piatt, biologist for the U.S. Geological Survey] said. To see such effect over two sizeable marine ecosystems is extraordinary, he said… Common murres eat small forage fish [which] were largely absent when the National Marine Fisheries Service conducted surveys in summer 2015… A conservative extrapolation indicates 500,000 or more common murres died, Piatt said. Nearly all were emaciated… “In 2016, we had widespread breeding failure at all of the colonies in the Gulf of Alaska, as well as the Bering Sea,” Renner said. “It was a highly unusual event. Murres don’t fail regularly.”… “They died of starvation because there was no food,” Piatt said. “There was no food because there was no fish.”…

KYUK, Jan 25, 2017: “The birds were underweight to the point of starvation,” [Shannon Atkinson of the University of Alaska Fairbanks] said. The number of starved murres, and the length of their die-off, was something no one had seen before, but murres in the Gulf of Alaska were not the only seabirds to die in large numbers last year. Tufted puffins in the Bering Sea also showed up on beaches in large numbers… Scientists struggled to understand why a bird that spends most of the winter offshore eating fish would fly to the coast to die of starvation on the beach… research showed a link between the starving birds and trawl surveys that came up empty, or with only a few of the forage fish normally eaten by murres… “The main result to take away from this is the catch per unit effort for all of these species was very close to zero, meaning that the forage fish was simply not there,” Atkinson said.

KUCB, Dec 7, 2016: In the past two months, 300 dead puffins have washed up on St. Paul Island, alarming residents who had only seen six carcasses over the last decade… scientists say it could be the sign of a much larger ecosystem problem… [The co-director of St. Paul’s Ecosystem Conservation Office said] ‘There are dead puffins everywhere.’… The carcasses came ashore in waves… [Lauren Divine, co-director of St. Paul’s Ecosystem Conservation Office] said the extent of the die-off was frightening… “After we opened up the first five, it was very apparent that all of them were emaciated,” she said. “Their muscles were completely atrophied. They had empty stomachs. They had gastrointestinal bleeding, which indicates severe long-term starvation. They were in very, very poor shape… So we started digging into this more,” said Divine. “What is happening? Where is their food?“… [T]he ECO office is also seeing signs of stress in other species. [Divine] said the island’s seabirds laid barely any eggs this season, hunters had a hard time finding sea lions, and crab quotas were cut sharply after a survey showed low numbers.

Dr. Caldicott: The radiation measurement is 530 sieverts, or 53,000 rems (Roentgen Equivalent for Man). The dose at which half an exposed population would die is 250 to 500 rems


HELEN CALDICOTT: The Fukushima nuclear meltdown continues unabated
https://nuclear-news.net/

Dr Helen Caldicott, explains recent robot photos taken of Fukushima’s Daiichi nuclear reactors: radiation levels have not peaked, but have continued to spill toxic waste into the Pacific Ocean — but it’s only now the damage has been photographed.

RECENT reporting of a huge radiation measurement at Unit 2 in the Fukushima Daichi reactor complex does not signify that there is a peak in radiation in the reactor building.

All that it indicates is that, for the first time, the Japanese have been able to measure the intense radiation given off by the molten fuel, as each previous attempt has led to failure because the radiation is so intense the robotic parts were functionally destroyed.

The radiation measurement was 530 sieverts, or 53,000 rems (Roentgen Equivalent for Man). The dose at which half an exposed population would die is 250 to 500 rems, so this is a massive measurement. It is quite likely had the robot been able to penetrate deeper into the inner cavern containing the molten corium, the measurement would have been much greater.

These facts illustrate why it will be almost impossible to “decommission” units 1, 2 and 3 as no human could ever be exposed to such extreme radiation. This fact means that Fukushima Daichi will remain a diabolical blot upon Japan and the world for the rest of time, sitting as it does on active earthquake zones.

What the photos taken by the robot did reveal was that some of the structural supports of Unit 2 have been damaged. It is also true that all four buildings were structurally damaged by the original earthquake some five years ago and by the subsequent hydrogen explosions so, should there be an earthquake greater than seven on the Richter scale, it is very possible that one or more of these structures could collapse, leading to a massive release of radiation as the building fell on the molten core beneath. But units 1, 2 and 3 also contain cooling pools with very radioactive fuel rods — numbering 392 in Unit 1, 615 in Unit 2, and 566 in Unit 3; if an earthquake were to breach a pool, the gamma rays would be so intense that the site would have to be permanently evacuated. The fuel from Unit 4 and its cooling pool has been removed.

But there is more to fear.

The reactor complex was built adjacent to a mountain range and millions of gallons of water emanate from the mountains daily beneath the reactor complex, causing some of the earth below the reactor buildings to partially liquefy. As the water flows beneath the damaged reactors, it immerses the three molten cores and becomes extremely radioactive as it continues its journey into the adjacent Pacific Ocean.

Every day since the accident began, 300 to 400 tons of water has poured into the Pacific where numerous isotopes – including cesium 137, 134, strontium 90, tritium, plutonium, americium and up to 100 more – enter the ocean and bio-concentrate by orders of magnitude at each step of the food chain — algae, crustaceans, little fish, big fish then us.

Fish swim thousands of miles and tuna, salmon and other species found on the American west coast now contain some of these radioactive elements, which are tasteless, odourless and invisible. Entering the human body by ingestion they concentrate in various organs, irradiating adjacent cells for many years. The cancer cycle is initiated by a single mutation in a single regulatory gene in a single cell and the incubation time for cancer is any time from 2 to 90 years. And no cancer defines its origin.

We could be catching radioactive fish in Australia or the fish that are imported could contain radioactive isotopes, but unless they are consistently tested we will never know.

As well as the mountain water reaching the Pacific Ocean, since the accident, TEPCO has daily pumped over 300 tons of sea water into the damaged reactors to keep them cool. It becomes intensely radioactive and is pumped out again and stored in over 1,200 huge storage tanks scattered over the Daichi site. These tanks could not withstand a large earthquake and could rupture releasing their contents into the ocean.

But even if that does not happen, TEPCO is rapidly running out of storage space and is trying to convince the local fishermen that it would be okay to empty the tanks into the sea. The Bremsstrahlung radiation like x-rays given off by these tanks is quite high – measuring 10 milirems – presenting a danger to the workers. There are over 4,000 workers on site each day, many recruited by the Yakuza (the Japanese Mafia) and include men who are homeless, drug addicts and those who are mentally unstable.

There’s another problem. Because the molten cores are continuously generating hydrogen, which is explosive, TEPCO has been pumping nitrogen into the reactors to dilute the hydrogen dangers.

Vast areas of Japan are now contaminated, including some areas of Tokyo, which are so radioactive that roadside soil measuring 7,000 becquerels (bc) per kilo would qualify to be buried in a radioactive waste facility in the U.S..

As previously explained, these radioactive elements concentrate in the food chain. The Fukushima Prefecture has always been a food bowl for Japan and, although much of the rice, vegetables and fruit now grown here is radioactive, there is a big push to sell this food both in the Japanese market and overseas. Taiwan has banned the sale of Japanese food, but Australia and the U.S. have not.

Prime Minister Abe recently passed a law that any reporter who told the truth about the situation could be gaoled for ten years. In addition, doctors who tell their patients their disease could be radiation related will not be paid, so there is an immense cover-up in Japan as well as the global media.

The Prefectural Oversite Committee for Fukushima Health is only looking at thyroid cancer among the population and by June 2016, 172 people who were under the age of 18 at the time of the accident have developed, or have suspected, thyroid cancer; the normal incidence in this population is 1 to 2 per million.

However, other cancers and leukemia that are caused by radiation are not being routinely documented, nor are congenital malformations, which were, and are, still rife among the exposed Chernobyl population.

Bottom line, these reactors will never be cleaned up nor decommissioned because such a task is not humanly possible. Hence, they will continue to pour water into the Pacific for the rest of time and threaten Japan and the northern hemisphere with massive releases of radiation should there be another large earthquake.

Kyodo, Feb 2, 2017 (emphasis added): Radiation level at Fukushima reactor highest since 2011 disaster — The radiation level inside the containment vessel of the No. 2 reactor at the crippled Fukushima Daiichi nuclear complex stood at 530 sieverts per hour at a maximum, the highest since the 2011 disaster, the plant operator said Thursday… The previously highest radiation level monitored in the interior of the reactor was 73 sieverts per hour.
https://english.kyodonews.jp/news/2017/02/456777.html

Kyodo, Feb 2, 2017: Record radiation level detected inside damaged Fukushima reactor… The reading means a person could die from even brief exposure, highlighting the difficulties ahead as the government and [Tepco] grope their way toward dismantling all three reactors that melted down…

Nikkei, Feb 3, 2017: Based on the “noise” in the images, the utility estimated that one area of the containment vessel was emitting radiation at a level of 530 sieverts per hour… Tepco previously believed that most of the reactor’s nuclear fuel had been contained in the pressure vessel, based on last year’s muon tomography inspection… But “it’s highly possible that melted fuel leaked through,” said Yuichi Okamura, a company spokesman for nuclear power.

Japan Times, Feb 2, 2017: Tepco finds gaping hole in grate under containment vessel… The hole could have been caused by melted fuel penetrating the vessel… Tepco plans to deploy a robot at the bottom of the containment vessel… to check out the conditions there… The actual condition of the melted fuel remains unknown because the radiation is too high…

Japan Times, Feb 3, 2017: The new radiation level, described by some experts as “unimaginable,” far exceeds 73 sieverts per hour, the previously highest radiation reading monitored in the interior of the reactor. An official of the National Institute of Radiological Sciences said medical professionals have never considered dealing with this level of radiation in their work.

NHK, Feb 2, 2017: [Tepco] says its latest estimation of the radiation level inside one of the reactors was extremely high and had the potential to be lethal to a human within a short period of time… An analysis of the images found that the radiation was up to 530 sieverts per hour at a concrete cylinder supporting the reactor… In the latest estimation inside the vessel, the area near its opening logged 50 sieverts per hour at maximum. The operator officials say that there are no leaks of gas with radioactive substances from the containment vessel. Officials suspect that fuel… may be emitting strong radiation inside the vessel.

Interview with nuclear engineer Hiroaki Koide (translation by Prof. Robert Stolz, transcription by Akiko Anson), published Mar 8, 2016 (emphasis added):
http://apjjf.org//2016/06/Hirano.html

Now, strontium-90 [Sr-90] has been leaking from Fukushima into the ocean, so it will eventually reach the United States, especially the west coast. This much we are sure of… it is the masses of people who need to realize the impact of the contamination on them. In the case of the Fukushima disaster, for example, they need to be aware that some radioactive material is reaching the North American coast, and the prevailing westerly winds will carry anything released into the atmosphere to the US…

While we are not really sure [how much radioactive material has leaked from Fukushima] we do know that a portion of this material will ride the prevailing winds across the Pacific Ocean. On the other hand, closer to the ground, the winds will be east, south, and north, and therefore this other portion will fall on Japan―and we can investigate the actual levels here: how much fell on this town, on this prefecture? Adding these up, it seems to be only 2.4 PBq. Which is to say of the total fifteen PBq, 2.4, or roughly only 16%, fell on Japanese soil. If the totals are higher, still a smaller share of the total contamination will have fallen on Japan compared with the Pacific, with the largest portion falling on the west coast of the United States.

So why don’t we hear complaints from the US? Why are there no calls for compensation? Whenever someone asks me this, I simply say that there just aren’t any such complaints. Why is this so? Well the levels released by the US during the atmospheric testing were tens of times greater than Fukushima. They are the criminals, so they cannot ask for compensation from Japan. The U.S. government does not want to have to reflect on its own past, and I think they are eager to completely avoid bringing up anything like that conversation.

Washington Post, Feb 10, 2016 (emphasis added): Five years after nuclear meltdown, no one knows what to do with Fukushima… one huge question remains: What is to be done with all the radioactive material?… Tepco has built a 1,500-yard-long “ice wall” around the four reactor buildings… however, Japan’s nuclear watchdog blocked the plan, saying the risk of leakage was still too high… [M]ost problematically, there’s the nuclear fuel from the plant itself… “The biggest challenge is going to be the removal of the nuclear fuel debris,” [Akira Ono, Tepco’s Fukushima Daiichi superintendent] said. “We don’t even know what state the debris is in at the moment.”… one of the options the government is considering is building a nuclear waste dump under the seabed, about eight miles off the Fukushima coast… Many groups… staunchly oppose the idea of burying the radioactive material at sea in such a seismically active area. “At some point it would leak and affect the environment,” said Hideyuki Ban, co-director of the Citizens’ Nuclear Information Center.

Japan Times, Feb 20, 2016: NRA commissioner suggests plan to remove all fuel debris at Fukushima plant may not be best option — A Nuclear Regulation Authority commissioner has suggested that removing all fuel debris from reactors at the meltdown-hit Fukushima No. 1 nuclear power plant may not be the best option. “I wonder if the situation would be desired that work is still underway to extract fuel debris 70 or 80 years after” the nuclear disaster, NRA Commissioner Toyoshi Fuketa told reporters Friday. “There are a variety of options, including removing as much fuel debris as possible and solidifying the rest,” he added… Fuketa said that unlike the disaster at the Chernobyl nuclear power plant, it is “not realistic” to construct concrete buildings to cover reactors at the Fukushima No. 1 plant because the situation is different. The commissioner also questioned whether construction of an underground ice wall around the reactor buildings to prevent radioactive water buildup will prove effective.

Tracking the Fallout and Fate of Fukushima Iodine-129 in Rain and Groundwater

Matt Herod, Univ, of Ottawa Ph.D Candidate, Dec 21, 2015 (emphasis added): A recently published paper (by myself and colleagues from uOttawa and Environment Canada) investigates… [Iodine-129] which was released by the Fukushima-Daichii [sic] Nuclear Accident… Within 6 days of the FDNA 129I concentrations in Vancouver precipitation increased 5-15 times… sampling of groundwater revealed slight increases in 129I… The results in rain show an increase in 129I concentrations of up to 220 million atoms/L… 129I anomalies [in groundwater wells], which occurred exactly when the recharge age predicted they would, suggests that some of the 129I deposited by Fukushima was reaching the wells… [P]ulses of elevated 129I occurred for another several months. Elevated 129I concentrations were measured in two wells… indicating that 129I from Fukushima can be traced into groundwater… [M]odeling has shown that 129I can be rapidly transported to the water table…

Scientists from Univ. of Ottawa’s Dept. of Earth Science and Environment Canada (Government of Canada), Dec 2015: The atmospheric transport of iodine-129 from Fukushima to British Columbia, Canada and its deposition and transport into groundwater

The Fukushima-Daiichi nuclear accident (FDNA) released iodine-129 (15.7 million year half-life)… The mean pre-accident 129I concentration in rain was [31,000,000 atoms/L]… following the FDNA, 129I values increased to [211,000,000 atoms/L]… [P]ulses of elevated 129I continued for several months…
The 129I in shallow… groundwater showed measurable variability through March 2013 with an average of [3,200,000 atoms/L]… coincident with modeled travel times…
Radionuclides released from the FDNA have been detected across the globe… [R]eleases of 129I and 131I… travel great distances…
The Abbotsford-Sumas Aquifer… spans the Canada–U.S. border between [B.C., Canada and Washington, US] and supplies ∼120,000 people with drinking water…
A pulse of 129I in precipitation with maximum concentrations of [211,000,000 atoms/L] in Vancouver and [221,000,000 atoms/L] at Saturna Island was observed 6 days following the FDNA. A value of [311,000,000 atoms/L] was also measured during the first week of July…
The high 129I concentrations while the FDNA was ongoing are attributed to the rapid trans-Pacific transport of 129I from Fukushima… This response in 129I concentrations shows that radionuclides from Fukushima were transported rapidly from Japan to the west coast of Canada and the US… [Sampling from Washington State], which is a composite of rainfall events spanning 15 March 2011 to 16 April 2011 shows a significantly elevated 129I concentration of [95,000,000 atoms/L]…
There was a spike in 129I concentration observed in the precipitation sample from the period of 1 July 2011 to 8 July 2011 [which] rose to [311,000,000 atoms/L]… a substantially higher concentration than any other sample… As monitoring at Fukushima detected no pulse of 129I in precipitation in July… this spike is likely due to a… nuclear fuel reprocessing facility. Modeling of the air parcel back trajectories… for the sampling period shows air mass trajectories from Hawaii, north Japan, and Russia…
The initial increase in 129I concentration at the water table appeared within ∼95 days, with a maximum concentration of [10,500,000 atoms/L]…
In the model cases, 129I reached the water table very rapidly…
Groundwater 129I concentrations in two nearby wells showed minor anomalies over the sampling period which could be due to rapid infiltration of the FDNA atmospheric 129I signal… [M]odeling shows that it was possible for a component of the 129I deposited by the FDNA to be conducted rapidly from the ground surface to the water table… We conclude that it is possible that a fraction of 129I from the FDNA is transported conservatively in this aquifer via preferential flow paths to the water table…
