Profiting from Wrongful Deception: Lamar Smith’s Attacks on Climate Science are Paid for by the Fossil Fuel Industry
George Orwell could not have dreamed up a more sinister and underhanded abuse of government and monetary power than the present brazen attempt by fossil fuel industry funded politicians to kill off today’s most important scientific messengers. But that’s exactly the intent Lamar Smith telegraphed last week in his most recent address to the anti-science Heritage Foundation when he said:
“Next week we’re going to have a hearing on our favorite subject of climate change and also on the scientific method, which has been repeatedly ignored by the so-called self-professed climate scientists.”

Oceanic dispersion of Fukushima-derived radioactive cesium: a review
This paper focuses on the radioactive Cs in seawater and summarizes estimates of the total amount of released radioactive Cs from the FNPP site, spatio–temporal changes in the concentrations of 134Cs and 137Cs not only off the coast of Fukushima and adjacent prefectures, but also in the North Pacific, and adjacent seas such as Japan Sea, East China Sea, based on measurement results and simulation models published during 4 years since the FNPP accident.

Oceanic dispersion of Fukushima-derived radioactive cesium: a review
Abstract
This review summarizes the more than 70 papers published during the 4 years since the Fukushima Dai-ichi nuclear power plant accident that occurred on 11 March 2011, and details the radioactive cesium dispersion pattern in the North Pacific and adjacent seas. The total amount of Fukushima-derived radioactive cesium released into the North Pacific via atmospheric deposition and direct release, spatial and temporal changes in the Pacific coast around the accident site, and the concentration levels of radioactive cesium around the Japanese Islands, not only the Pacific coast but also in adjacent seas, such as Japan Sea, East China Sea are summarized. Based on observational data mostly obtained during 2 years since the accident, and simulation results, oceanic dispersion of radioactive cesium in the entire area of the North Pacific is described. The Fukushima-derived radioactive cesium dispersed eastward as surface water and extended to the eastern side of the North Pacific in 2014, and was also observed via a southward intrusion to subsurface waters as Subtropical Mode Water and Central Mode Water. The radioactive cesium movement related to mode water is important in terms of the circulation of cesium into the ocean interior. Some new technologies and techniques concerning emergency monitoring of radioactivity in the ocean environment are also reported, the effectiveness of which has been demonstrated by use in relation to the Fukushima accident.
Introduction
On 11 March 2011, the Great East Japan Earthquake (Mw 9.0) occurred at the plate boundary off the coast of Tohoku, northeastern Japan. A huge tsunami was generated and caused 15 729 fatalities and 4539 missing in the Hokkaido, Tohoku and Kanto regions (The National Police Agency, as of 24 August 2011). Preliminary surveys reported tsunami waves with run-up heights exceeding 30 m (Mori et al., 2011). The tsunami also hit the Fukushima Dai-ichi Nuclear Power Plant (FNPP) sites located at 37˚25’N, 141˚02’E, and a loss of electric power at FNPP resulted in overheated reactors and hydrogen explosions. Radioactive materials were then released into the ocean through atmospheric fallout (such as aerosols and precipitation) and as direct releases (controlled releases related to safety issues at FNPP) as well as uncontrolled leaking of the heavily contaminated coolant water (Buesseler et al., 2011; Chino et al., 2011; Takemura et al., 2011). This accidental release of anthropogenic radionuclides (mostly iodine-131, cesium-134 and -137; 131I, 134Cs and 137Cs) resulted in severe elevations of these radionuclides in fisheries products in the coastal areas of Fukushima and adjacent prefectures (Buesseler, 2012; Yoshida and Kanda, 2012; Wada et al., 2013; Nakata and Sugisaki, 2015). Owing to its relatively long half-life (2.07 years for 134Cs and 30.07 years for 137Cs), the evaluation of these radioactive Cs isotopes in the marine environment is important for addressing risks to both marine ecosystems and public health through consumption of fisheries products. Generally, cesium is a conservative element and mostly occurs in the dissolved phase in the marine environment. The concentration of radioactive cesium in marine organisms is strongly affected by its concentration in the surrounding seawater. Actually, temporal changes in radioactive Cs concentrations of many pelagic fish species in the near coastal area off Fukushima and adjacent prefectures were associated with those in seawater after the FNPP accident (e.g., Wada et al., 2013; Takagi et al., 2015; Morita et al., unpublished data). Kaeriyama et al. (2015) and Morita et al. unpublished data revealed the time-lagged temporal changes in radioactive Cs in organisms (zooplankton and Pacific saury) and seawater under non-steady-state conditions after the FNPP accident, and showed that the concentration ratios in these organisms had been elevated when compared with those before the FNPP accident. With regard to zooplankton, Baumann et al. (2015) discussed the possible uptake of Fukushima-derived radioactive Cs from phytoplankton dominated suspended particles. As a consequence, radioactive Cs would be transferred to the higher trophic level not only via surrounding seawater but also by prey-predator interactions in the pelagic ecosystem. Shigenobu et al. (2014) reported the radioactive Cs concentrations of fat greenling (Hexagrammos otakii) caught off the coast of Fukushima Prefecture, and reported two outlier specimens caught in August 2012 and May 2013 which had ambiguously high 137Cs concentrations of more than 1000 Bq/kg-wet. Probability analysis indicated that the two outlier fat greenlings had migrated from the port of FNPP. In the port of FNPP, extremely high 137Cs concentrations were reported from Japanese rockfish (Sebastes cheni), brown hakeling (Physiculus maximowiczi) and fat greenling (H. otakii) caught during January and February 2013 (Fujimoto et al., 2015). The maximum concentration of 137Cs (129 kBq/kg-wet) was detected from fat greenlings. Wada et al. (2013) with the corrigendum (Wada et al., 2014) summarized the monitoring results of radioactive Cs concentrations in fisheries products from Fukushima Prefecture and revealed time-series trends. Clear trends include a slower decrease of radioactive Cs in demersal fish compared to pelagic fish as well as spatial heterogeneity; specimens sampled in the area south of FNPP tended to have higher concentrations of radioactive Cs than those caught in the area north of FNPP. Sohtome et al. (2014) reported the time-course trends in concentration of radioactive Cs in invertebrates in the coastal benthic food web near the FNPP. The difference in decreasing trends observed within the organisms and the concentrations of radioactive Cs in some of the sea urchins (Echinocardium cordatum and Glyptocidaris crenularis) were clearly affected by the contaminated sediments taken into their digestive tract.
This paper focuses on the radioactive Cs in seawater and summarizes estimates of the total amount of released radioactive Cs from the FNPP site, spatio–temporal changes in the concentrations of 134Cs and 137Cs not only off the coast of Fukushima and adjacent prefectures, but also in the North Pacific, and adjacent seas such as Japan Sea, East China Sea, based on measurement results and simulation models published during 4 years since the FNPP accident.
Total Amount of FNPP–Released Radioactive Cesium
Information on the total amount of the FNPP-released radioactive Cs into the North Pacific is critical information to enable effective monitoring and resource management. However, despite its importance, estimation of atmospheric deposition is complex due to lack of the observational data in the oceanic environment. The activity ratios of 134Cs/137Cs, decay corrected to March–April 2011, were reported to be almost 1.0 for the entire North Pacific (e.g., Buesseler et al., 2011, 2012; Kaeriyama et al., 2014). This ratio means an equivalent amount of 134Cs and 137Cs was released into the ocean. Under the limitation of data concerning not only the amount of radioactive Cs in aerosols but also on precipitation in the North Pacific, estimation of atmospheric deposition remains a source of considerable uncertainty (5–15 PBq of 134Cs and 137Cs; 1 PBq = 1015 Bq, Table 1). In contrast, the direct release of radioactive Cs (134Cs and 137Cs) into the ocean as uncontrolled leaking of the heavily contaminated coolant water is well estimated as approximating the value of 3.5 PBq, with the exception of Bailly du Bois et al. (2012) and Charette et al. (2013) (Table 1). Dietze and Kriest (2012) discussed the possible overestimates by Bailly du Bois et al. (2012) as a result of methodological issues. Charette et al. (2013) estimated the direct release inventory from the observational data of radioactive Cs with radium isotopes in May–June 2011, and no atmospheric deposition was assumed. Their estimates of direct releases may be included in the atmospheric deposition. Tsumune et al. (2012) clearly showed that direct releases started on 26 March 2011 using 131I/137Cs activity ratios, which varied much more before 26 March 2011 when the atmospheric deposition was the major source. The most recent estimations have revealed that 3–4 PBq of 134Cs and 137Cs were directly released into the ocean and 12–15 PBq of 134Cs and 137Cs were deposited on the surface seawater in the North Pacific (Aoyama et al., 2015a).

The Nos. 3 and 4 reactors at the Takahama nuclear power plant
Japan court rules in favor of restart of Kansai Elec’s Takahama reactors
A Japanese high court on Tuesday overturned a lower court’s order to shut two reactors operated by Kansai Electric Power, a company spokesman said, potentially ending a drawn-out legal battle and helping the utility to cut fuel costs.
The decision, while positive for Kansai Electric, is not likely to speed the broader process of getting reactors back online nationally after the Fukushima nuclear disaster of six years ago, said a former advisor to the government and others.
“The future of nuclear power is still uncertain. The decision does not mean that the courts will give a ‘yes’ to other legal cases. Political uncertainty remains strong, too,” said Tatsujiro Suzuki, a former vice chairman of the Japan Atomic Energy Commission, a government body.
The Osaka High Court overturned the first court-ordered shutdown of an operating nuclear plant in Japan. The lower court had decided last year in favor of residents living near the Takahama atomic station west of Tokyo after they had petitioned for the reactors at the plant to be shut.
Kansai Electric, Japan’s most nuclear-reliant utility before the disaster, estimates it will save 7 billion yen ($63 million) per month in fuel once it restarts both reactors.
The restart schedule for the reactors, however, is still uncertain because the utility has been conducting safety checks requested by local authorities after a large crane toppled onto another reactor building at the site due to strong winds in January, a Kansai Electric spokesman said earlier.
There are four reactors at the Takahama plant, with the earlier court order covering the two newest ones.
The company released a profit forecast after the verdict on Tuesday saying it estimates net income of 133 billion yen ($1.2 billion) in the year through March 31, 2017.
The Kansai case was one of many going through the courts after the Japanese public turned away from nuclear power following the Fukushima meltdowns of 2011, the world’s worst nuclear calamity since Chernobyl in 1986.
Just three out of Japan’s 42 operable reactors are running and the pace of restarts has been protracted despite strong support from Prime Minister Shinzo Abe’s government, which is keen to restore a power source that provided about a third of electricity supply before the Fukushima disaster.
Residents have lodged injunctions against nuclear plants across Japan and lower courts have been increasingly siding with them on safety concerns.
Contentious verdicts are usually overturned by higher courts, where judges tend to be more attuned to government policy, judicial experts say.
“We are going to win some and we are going to lose some, but the political and social situation is such that unstable prospects for restarts are here to stay,” Aileen Mioko Smith, an advisor to the plaintiffs and a co-plaintiff in other lawsuits, told Reuters by phone from Osaka.
There are more than 30 cases going through Japan’s courts in which communities are seeking to stop reactors from operating, she said.
Kansai Electric shares had ended trading before the court decision was released. They closed 0.3 percent higher on Tuesday at 1,283 yen, while the broader market rose more than 1 percent.

Columban missionary backs bishops against nuclear industry after harrowing visit to Fukushima clean-up
Evacuated: An evacuee rests in a gymnasium serving as an evacuation centre in Yamagata, Japan, in March 2011. Residents from the vicinity of Fukushima Dai-ichi nuclear power plant were sheltered at the gym, as officials and workers struggled to contain the situation at the badly damaged nuclear facility.
A COLUMBAN missionary has witnessed a massive contamination clean-up in the Japanese region surrounding Fukushima, where a 2011 earthquake and tsunami triggered a nuclear power plant meltdown.
Fr Paul McCartin, recently visited the Fukushima region, six years after the nuclear disaster, and ahead of a government evacuation order being lifted at the end of this month, which will allow people to return home.
Arriving by bullet train at the town of Kouriyama, 60km west of Fukushima Number One Nuclear Power Plant, Fr McCartin said the first surprise was the large radiation monitor in front of the station.
“Over the next three days I saw similar monitors in cities, beside country roads and along expressways,” Fr McCartin, the Columban Justice, Peace and the Integrity of Creation co-ordinator in Japan, said.
He has worked in Japan since 1979 and visited the Fukushima last September.
“I had taken face masks but our guides gave us better ones,” he said.
“We were told to make sure we washed our hands and around our mouths before eating.
“I was given a small radiation monitor to wear around my neck.
“Over the two-and-a-half days I was exposed to 8.1 micro Sieverts, an ‘acceptable’ amount.”
The Sievert is a measure of the health effect of low levels of ionising radiation on the human body.
As Fr McCartin drove through the Fukushima countryside, he found houses barricaded, roads closed and warnings from officials amidst a massive clean-up.
“I was restricted. There were roadblocks with security personnel,” he said.
“I was advised not to hike in Fukushima as there is a lot of radiation in the mountains, especially at the base of mountains as rain washes it down.
“Buildings and roads are being washed down, and contaminated soil and vegetation being removed.”
He said topsoil to a depth of five centimetres was being removed and replaced with soil from unaffected areas.
“There are large collections of industrial waste bags all over the place. There must be hundreds of thousands, if not millions,” he said.
At the end of March, Japan is set to lift evacuation orders for parts of Namie, located 4km from the wrecked Fukushima Daiichi nuclear plant, as well as three other towns.
More than half of Namie’s former 21,500 residents have decided not to return.
Namie, and other nearby centres are now ghost towns, dilapidated, and for many, they conjure horrific memories.
Tsunami damage: Facilities near the seawater heat exchanger building at Tokyo Electric Power Company’s Fukushima Daini nuclear power plant Unit 3 reactor on April 2, 2011, days after an earthquake and tsunami hit the area in north-east Japan.
A government survey showed last year, there were lingering concerns over radiation and the safety of the nuclear plant, which is being decommissioned.
Beyond radiation risks, an unexpected nuisance looms – hundreds of wild boars have descended from surrounding hills and forests into the deserted towns.
The creatures have roamed across the radioactive contaminated region.
In Namie, wild boars occupy the empty streets and overgrown backyards foraging for food.
In the nearby town of Tomioka, local hunters have captured an estimated 300 boars.
Following his visit last September, Fr McCartin is concerned about the spread of contaminated material.
“Low-level waste is being recycled,” he said.
“Highly contaminated waste is being burned.
“So far only one per cent of high-level waste has been burned.
“More incinerators are being constructed.
“Contaminated waste is being used in the wall being built along the shore to prevent another tsunami hitting the area.
“In fact, there is so much radioactively contaminated waste that local facilities can’t handle it, so ‘low-level waste’ is being transported to many distant places for disposal.
“Contaminated fishing gear and nets are being disposed of in the town where I live.
“In this way, radiation is being spread to many parts of the country.
“It would seem to make sense to keep it where it is and avoid unnecessarily contaminating the rest of the country.”
Fr McCartin said the Japanese media was muzzled from challenging the government on Fukushima and the hazards of nuclear power.
The efforts of individual journalists reporting on the issue were often dismissed.
“A Catholic in Yokohama told me last year that after his daughter wrote a piece on Fukushima for the newspaper she works for, her boss told her, ‘No more on Fukushima’,” he said.
“The government has threatened to shut down any media organisation that publishes something the government doesn’t like.
“In the last year or so three forthright and prominent media personalities have been sacked or not had their contracts renewed.”
Fr McCartin said he supported a call by Japanese Catholic bishops to abandon the nuclear power industry.
“I believe that if the government transferred a small fraction of the trillions of dollars it throws at the nuclear industry to the renewable energy industry, the country would be awash in safe energy in a very short time,” he said.
Some Fukushima municipalities lack nuclear evacuation plans as no-entry orders lifted
Of the 11 municipalities in Fukushima Prefecture which came under evacuation orders after the 2011 Fukushima No. 1 nuclear plant meltdowns, five do not have evacuation plans in case a nuclear accident occurs again, even though no-entry orders are gradually being lifted.
The central government requests local municipalities located near nuclear power plants to draw up evacuation plans in case of a nuclear emergency. According to central government policy, local governments should issue immediate evacuation orders to residents living within 5 kilometers of a plant in case of a “full-scale emergency” — situations including the loss of cooling power at nuclear reactors.
As a basic rule, those living between 5 and 30 kilometers from a plant are subject to indoor evacuation, and when a radiation dose of 20 microsieverts per hour is detected, evacuation should be completed within one week. Immediate evacuation is recommended when the dose hits 500 microsieverts per hour.
A representative of the village of Katsurao, whose residents have started moving back, told the Mainichi Shimbun that the municipal government has not created its evacuation plan because “there are only two officials in charge of the matter.” The official added, “We don’t have expert knowledge (about nuclear evacuations) and we can’t handle it with all the other work we have to do. Neither the state nor the Fukushima Prefectural Government is giving us advice.”
An official from the village of Iitate, where the evacuation order will be lifted at the end of March, said in addition to a workforce shortage, “it’s difficult to make a plan before examining how many residents will come back.” The city of Tamura, whose residents have started coming back, and the towns of Futaba and Okuma, where it remains unknown when residents will be able to return, do not have evacuation plans.
Meanwhile, the towns of Namie and Tomioka have mapped out their plans, which take the basic principle of evacuating all townspeople in case of a full-scale emergency — more drastic measure than central government policy requires — saying that just following the state’s evacuation policy will not protect their residents’ safety. Namie Mayor Tamotsu Baba told the Mainichi, “Residents don’t believe they would be safe if they remain inside a building.”
With regard to local evacuation plans, a support team for nuclear accident victims at the Cabinet Office points out that while such plans are not requirement for the state to lift evacuation orders, local governments should prepare disaster prevention measures.
The stricken Fukushima No. 1 nuclear plant is different from other nuclear stations in the country as decommissioning work is in progress for all its six reactors. At the same time, a rough road is expected for the project to remove melted fuel, and the estimated hourly radiation dose inside No. 2 reactor is as much as 650 sieverts.
According to an opinion poll by the Reconstruction Agency targeting residents of the city of Tamura, 61.5 percent of those who said they wanted to live in other municipalities than Tamura cited concerns over decommissioning work and management of the nuclear plant as reasons for not wanting to come back.
Hirotada Hirose, professor emeritus at Tokyo Woman’s Christian University and an expert in nuclear disaster prevention, commented, “The condition of melted nuclear fuel (at the Fukushima plant) is unknown and aftershocks are still continuing in Fukushima Prefecture. It’s a problem that evacuation orders are being lifted while local governments have not come up with their evacuation plans.”

A-bomb survivor calls for nuclear arms ban
A survivor of the 1945 atomic bombing of Hiroshima has called for the creation of a new global treaty to prohibit nuclear weapons.
Toshiki Fujimori spoke in New York on Sunday at a meeting of the International Campaign to Abolish Nuclear Weapons. The NGO group held the meeting ahead of the start of UN negotiations on a legally binding international nuclear ban treaty.
Fujimori experienced the bombing when he was 16 months old. He is scheduled to speak on the first day of the UN negotiations.
Fujimori expressed hope for the talks, which he referred to as an attempt to draw up a treaty that has yet to arrive due to strong pressure from nuclear powers.
He said the voices of atomic bomb survivors and their numerous supporters have spurred momentum to ban the weapons. He said such voices remind the world of the inhumanity of nuclear weapons, which cause indiscriminate mass destruction of human life and inflict radiation on survivors.
He stressed that while their exposure problems are at different stages, each of the 170,000 survivors still alive in Japan has a cross to bear until death.
He urged people to listen to the cries of survivors and move a step forward toward achieving a world free of nuclear weapons
Japan ponders recycling Fukushima soil for public parks & green areas
Workers move big black plastic bags containing radiated soil. Fukushima prefecture, near Fukushima Daiichi nuclear power plant.
Soil from the Fukushima prefecture may be used as landfill for the creation of “green areas” in Japan, a government panel has proposed, facing potential public backlash over fears of exposure to residual radiation from the decontaminated earth.
The advisory panel of the Environment Ministry on Monday proposed reusing soil that was contaminated during the Fukushima nuclear meltdown of 2011 as part of future landfills designated for public use, Kyodo news reported.
In its proposal, the environmental panel avoided openly using the word “park” and instead said “green space,” apparently to avoid a premature public outcry, Mainichi Shimbun reported.
Following an inquiry from the news outlet, the Ministry of the Environment clarified that “parks are included in the green space.”
In addition to decontaminating and recycling the tainted earth for new parks, the ministry also stressed the need to create a new organization that will be tasked with gaining public trust about the prospects of such modes of recycling.
To calm immediate public concerns, the panel said the decontaminated soil will be used away from residential areas and will be covered with a separate level of vegetation to meet government guidelines approved last year.
In June last year, the Ministry of the Environment decided to reuse contaminated soil with radioactive cesium concentration between 5,000 to 8,000 becquerels per kilogram for public works such as nationwide roads and tidal banks.
Under these guidelines, which can now be extended to be used for the parks, the tainted soil shall be covered with clean earth, concrete or other materials.
Such a landfill, the government said at the time, will not cause harm to nearby residents as they will suffer exposure less than 0.01 mSv a year after the construction is completed.
The Fukushima Daiichi nuclear power plant suffered a blackout and subsequent failure of its cooling systems in March 2011, when it was hit by an earthquake and a killer tsunami that knocked out the facility, spewing radiation and forcing 160,000 people to flee their homes. Three of the plant’s six reactors were hit by meltdowns, making the Fukushima nuclear disaster the worst since the Chernobyl catastrophe in 1986.

Gov’t proposes reusing Fukushima’s decontaminated soil on green land
The Environment Ministry on Monday proposed reusing decontaminated soil from disaster-hit Fukushima Prefecture as landfill for parks and green areas.
At a meeting of an advisory panel, the ministry also called for launching a new organization to map out plans on how to gain public understanding about the reuse of decontaminated soil, ministry officials said.
The proposals come at a time when Fukushima Prefecture faces a shortage of soil due to the decontamination work following the 2011 nuclear meltdown.

State to appoint Tepco’s new president
TEPCO to reshuffle top managers
Some big changes are in store for the boardroom of the company that operates the Fukushima Daiichi nuclear plant. A planned reshuffle at Tokyo Electric Power Company Holdings is aimed at speeding up work at the crippled plant and moving ahead with business reforms.
The government owns a majority of the shares in TEPCO Holdings, giving it effective control. The company faces a decades-long task of decommissioning the melted down reactors and paying compensation.
Sources say government officials are now putting the finishing touches on a plan to replace Chairman Fumio Sudo. Taking his place will be Takashi Kawamura, chairman emeritus of electronics-maker Hitachi.
TEPCO Holdings President Naomi Hirose will become vice chairman and he’s going to focus on efforts to help revitalize Fukushima Prefecture.
Tomoaki Kobayakawa, who heads the group’s retail unit, will be taking over his job.
TEPCO plans to hold a board meeting as early as Friday to formally approve the new lineup.

State taps director Kobayakawa to become Tepco’s next president
The government plans to appoint Tomoaki Kobayakawa, a director on the board of Tokyo Electric Power Company Holdings Inc., as president of the nationalized utility, it was learned Sunday.
Kobayakawa, 53, is president of Tepco Energy Partner Inc., a retail subsidiary.
The government plans to have Tepco President Naomi Hirose, 64, step aside to take the post of vice chairman so he can concentrate on decommissioning the disaster-stricken Fukushima No. 1 nuclear plant and compensating the people and businesses affected by the March 2011 triple core meltdown, informed sources said.
To replace Tepco Chairman Fumio Sudo, 76, the government has already asked Takashi Kawamura, 77, honorary chairman of Hitachi Ltd.
Tepco plans to adopt the appointments this month. The new management team is expected to be launched after a shareholders meeting in June.
Tepco is expected to invite Shoei Utsuda, 74, who advises trading house Mitsui & Co., and Kazuhiko Toyama, 56-year-old chief executive officer of Industrial Growth Platform Inc., as outside board members.
By revamping Tepco’s top management, the government hopes to speed up its reform mainly through operational realignment that may involve other companies. This is aimed at improving its competitiveness and raising funds to finance the enormous costs of dealing with the man-made nuclear accident triggered by the March 2011 earthquake and tsunami, according to the sources.
The leaders of Tepco’s subsidiaries are also expected to be replaced.
With Kobayakawa at the helm, the holding company plans to rejuvenate its management team and promote rehabilitation under the leadership of Kawamura, who engineered the drastic recovery of Hitachi’s earnings.
The new Tepco team will face the challenge of balancing work to address the consequences of the world’s worst nuclear disaster since Chernobyl and boosting its earnings capacity.
Tepco plans to draw up soon a new business reconstruction program calling for, among other steps, the integration of its electricity transmission and nuclear businesses with other companies.
