No human rights in terrifyingly contaminated Namie in Fukushima
The evacuation orders of the most populated areas of Namie, Fukushima were lifted on March 31, 2017.
We are publishing the most recent soil surface density map of Namie created by a citizen’s measurement group named the “Fukuichi Area Environmental Radiation Monitoring Project“(http://www.f1-monitoring-project.jp/index.html). Their members are mainly from Tokyo metropolitan region.
Their map is simply terrifying. This is far much higher level of radio-contamination than in the Radiation Control Zone. Any area becomes designated as such when the total effective dose due to external radiation and that due to radioactive substances in the air is likely to exceed 1.3mSv per quarter – over a period of three months, or when the surface density is likely to exceed 40,000Bq/m2. In the Radiation Control Zone, it is prohibited to drink, eat or stay overnight. Even adults, including nuclear workers, are not allowed to stay more than 10 hours. To leave the zone, one has to go through a strict screening.
Namie’s radio contamination is far over these figures! The average soil contamination density of the total of 314 points where the soil was collected and measured is 858,143Bq/m². The maximum value was 6,780,000Bq/m², and the minimum was only 31,400Bq/m²!
And people, including infants and pregnant women, are told to go back to these areas to live, because it is supposed to be safe. Basically the Japanese government does not recognize the fundamental human right to live in a healthy environment. The population is facing a tough future, for the compensation will be cut off soon, and the housing aid by the central government finishes at the same time. As for the auto-evacuees who fled from areas which are not classified as evacuation zones but are nevertheless radio-contaminated, they had only very little compensation and the housing aid was cut off at the end of March 2017. Continuing to live as nuclear refugees is becoming more and more difficult. We consider that this is a violation of basic environmental human rights.
Let us not forget to thank the members and volunteers of the Fukuichi Area Environmental Radiation Monitoring Project team. They are mostly elderly people over 60 years old. However, that doesn’t mean that they can be exposed to radiation. We thank them and pray for their health.

You might think that Japanese just endure their fate without complaining. This is not true. Many people are fighting and protesting. Let us cite, among numerous on-going trials, the one called the “Trial to require the withdrawal of the 20mSv dose as the limit for evacuation” filed by residents of Minamisoma city in Fukushima, who are against the lifting of the evacuation order when the radiation dose decreases below 20mSv/year. Let us remind you that the Japanese government has adopted 1mSv/year, the internationally recognized dose limitation for public recommended in 1990 by ICRP (International Commission on Radiological Protection), and this is still the limit for the public all over Japan EXCEPT in Fukushima. This is one of the reasons why many people from Fukushima ask themselves: “Is Fukushima really a part of Japan?” or “Are we the people abandoned by the State?”

An election campaign in an unknown town
31/7/2017 by Mayumi MATSUMURA
Yesterday morning, while I was waiting with my mother-in-law the pickup bus from the Day Care Center for the Elderly, I heard voices approaching. They seemed to say “Good morning” using a loudspeaker attached to an advertising car.
However, the voices were weak, considering that they came from a loudspeaker. They also seemed very reserved and embarrassed to disturb people. (Translator’s note: In Japan during the election time, candidates and their teams roam the streets in vehicles shouting their names and asking for support). I listened. The voices said: “Good morning, I am XXXX, candidate for the election of the mayor of Tomioka”.
The voices were really reserved, weak …
They made me so sad. Profoundly moved, I opened the kitchen window and waved my hands.
The first car stopped.
The voice said, “Oh, thank you, thank you. ”
“Courage and good luck! I’m sorry, I’m not from Tomioka, but … ” I said.
A voice replied, “Thank you, thank you for your words of support.”
I waved my hands and shouted words of encouragement to the second and third vehicle where the candidate was seated.
My eyes were filled with tears.
They run an election campaign in an unknown city, without knowing where the residents of Tomioka are, where their voters took refuge.
If it were their own town, they would campaign with dignity from the electoral car in a loud voice. But they were belittling themselves, roaming through the unknown streets.
Tears have troubled the visions.
However, I continued to wave my hands until the vehicles disappeared.
It has been 6 years and 4 months since we left our home.
There will never be a restful end to our journey.

Footage from reactor 3 may force rewrite of Fukushima road map, officials say
This underwater robot was used in the recent probe of reactor 3 at the Fukushima No. 1 power plant.
The first images of melted fuel from the crippled Fukushima No. 1 power plant indicate that it did not burn through the pressure vessel of reactor 3, but exited through the holes used to insert the control rods, officials say.
While the landmark robot footage from the primary containment vessel of unit 3 is helping Tokyo Electric grasp the reality of the damaged fuel assemblies, it may also force it to rewrite the road map for decommissioning the meltdown-hit plant.
Tokyo Electric Power Company Holdings Inc., better known as Tepco, sent an underwater robot into reactor 3 earlier this month to confirm its hypothesis that the core — the fuel assemblies in the pressure vessel — broke apart and fell to the bottom, letting molten fuel burn through and drip into the primary containment vessel.
According to Tepco spokesman Takahiro Kimoto, however, the images taken beneath the PCV indicate the pressure vessel probably withstood the heat of the molten fuel. He said the fuel apparently seeped through the holes for the control rods.
“We do not presume that the vessel, which is 14 cm thick, melted and collapsed together with the fuel, but that part of the fuel instead made its way down through holes,” Kimoto said. The control rods are used to moderate the chain reaction and are inserted vertically into the core.
Tepco said it estimates reactor 3 has about 364 tons of fuel debris, and that similar amounts will be found in reactors 1 and 2. Removing the fuel from the reactors is the largest challenge in defueling the aged plant — a process that could take up to 40 years to complete.
The camera on the underwater robot also captured images of rubble around the fuel debris, which could slow the removal process. The rubble includes devices for supporting the control rods at the bottom of the PCV and scaffolding for maintenance workers beneath the pressure vessel.
Minister of Economy, Trade and Industry Hiroshige Seko said the government and Tepco will try to draft a plan for removing the melted fuel in September, with an eye to hammering out the specifics in the first half of fiscal 2018 and starting the work in 2021.
But the findings from reactor 3 may force them to alter the state’s road map for decommissioning Fukushima No. 1, officials said.
An entity providing technical support for the project has urged that efforts be made to remove the melted fuel from the submerged lower part of the PCV by keeping air in the upper part, according to a source familiar with the plan.
Although filling the PCV completely with water would largely reduce the radiation risk to the robot probes, the Nuclear Damage Compensation and Decommissioning Facilitation Corp. is reluctant to do so because it is damaged and the toxic water will just leak out, the source said.
At the other two reactors, Tepco thinks most of the fuel in reactor 1 fell to the bottom of the primary containment vessel, and that some of the fuel in reactor 2 remained in the pressure vessel. The company made the estimates based on cosmic ray imaging analysis and by sending robots and endoscopes into the PCVs of the two reactors.

Gov’t says 70% of land suitable for nuclear waste disposal
The Japanese government unveiled Friday a map indicating potential deep-underground disposal sites for high-level radioactive nuclear waste, identifying some 70% of the country’s land as suitable.
Based on the map, the government is expected to ask multiple municipalities to accept researchers looking into whether those areas can host sites to dispose of waste left by nuclear power generation. But the process promises to be both difficult and complicated amid public concerns over nuclear safety following the 2011 Fukushima nuclear disaster.
The nationwide map showed that up to 900 municipalities, or half of the country total, encompass coastal areas deemed “favorable.” Areas near active faults, volcanoes and potential drilling sites such as around oil fields are considered unsuitable.
For permanent disposal, high-level radioactive waste, produced as a result of the process of extracting uranium and plutonium from spent fuel, must be stored more than 300 meters underground so that it cannot impact human lives or the environment.
The government will store the waste in vitrified canisters for up to some 100,000 years until the waste’s radioactivity decreases.
As of March, some 18,000 tons of spent fuel existed in Japan with the figure set to increase as more nuclear plants resume operation. When spent fuel that has already been reprocessed is included, Japan will have to deal with about 25,000 such canisters.
The map, illustrated in four different colors based on levels of the suitability of geological conditions, was posted on the website of the Ministry of Economy, Trade and Industry.
Energy minister Hiroshige Seko said Friday that the unveiling of the colored map is an “extremely important step toward the realization of the final disposal but also the first step of a long road.”
Taking the map as an opportunity, “we hope to have communications (with municipalities) nationwide and earn the understanding of the public,” he said.
“It scientifically and objectively shows nationwide conditions, but it is not something with which we will seek municipalities’ decisions on whether to accept a disposal site,” Seko said.
Areas near active faults, volcanoes and oil fields which are potential drilling sites are deemed unsuitable because of “presumed unfavorable characteristics” and colored in orange and silver.
Areas other than those are classified as possessing “relatively high potential” and colored in light green.
Among the potential areas, zones within 20 kilometers of a coastline, around 30 percent of total land, are deemed especially favorable in terms of waste transportation and colored in green.
The map has also colored as suitable a part of Fukushima Prefecture, where reconstruction efforts are underway from the 2011 massive earthquake and tsunami that led to the Fukushima nuclear plant disaster.
But Seko said the government has no plans at this stage to burden the prefecture additionally with the issue of disposal of high-level radioactive waste.
The minister also indicated that Aomori Prefecture in northeastern Japan, home to a facility to reprocess nuclear fuel, is exempt as the prefectural government and state have agreed not to construct a nuclear waste disposal facility there.
Japan, like many other countries with nuclear plants, is struggling to find a permanent geological disposal repository, while Finland and Sweden are the only countries worldwide to have decided on final disposal sites.
A process to find local governments willing to host a final repository site started in 2002 in Japan, but little progress was made due mainly to opposition from local residents.
In 2015, the government decided to choose candidate sites suitable on scientific grounds for building a permanent storage facility, rather than waiting for municipalities to offer to host such a site.
The government aims to construct a site that can house more than 40,000 canisters, with estimated costs amounting to 3.7 trillion yen ($33 billion).
Fukushima Unit 2 Radiation Readings Revised
TEPCO revised unit 2’s containment inspection radiation readings done earlier in 2017, claiming a set of instrument and calibration errors caused the inaccurate readings.
TEPCO claims that their camera based radiation estimates were too high due to an oversight where they forgot to reset the sensitivity threshold on the equipment that was reading camera interference.
The final claim made in the report for downgrading the radiation readings was that one of the 4 sensors was reading considerably higher than the other 3. When they took that sensor out of the readings the other 3 sensors read considerably lower.

Study: Radioactive Hot Particles Still Afloat Throughout Japan Six Year After Fukushima Meltdowns
Radioactive particles of uranium, thorium, radium, cesium, strontium, polonium, tellurium and americium are still afloat throughout Northern Japan more than six years after a tsunami slammed into the Fukushima Daiichi Power Plant causing three full-blown nuclear meltdowns. That was the conclusion reached by two of the world’s leading radiation experts after conducting an extensive five-year monitoring project.
Arnie Gundersen and Marco Kaltofen authored the peer reviewed study titled, Radioactively-hot particles detected in dusts and soils from Northern Japan by combination of gamma spectrometry, autoradiography, and SEM/EDS analysis and implications in radiation risk assessment, published July 27, 2017, in Science of the Total Environment (STOLEN).
Gundersen represents Fairewinds Associates and is a nuclear engineer, former power plant operator and industry executive, turned whistleblower, and was CNN’s play-by-play on-air expert during the 2011 meltdowns. Kaltofen, of the Worcester Polytechnic Institute (WPI), is a licensed civil engineer and is renowned as a leading experts on radioactive contamination in the environment.
415 samples of “dust and surface soil” were “analyzed sequentially by gamma spectrometry, autoradiography, and scanning electron microscopy with energy dispersive X-ray analysis” between 2011 and 2016. 180 of the samples came from Japan while another 235 were taken from the United States and Canada. The study further clarifies, “Of these 180 Japanese particulate matter samples, 57 were automobile or home air filters, 59 were surface dust samples, 29 were street dusts (accumulated surface soils and dusts) and 33 were vacuum cleaner bag or other dust samples.”
108 of the Japanese samples were taken in 2016, while the other 72 were gathered in 2011 after the meltdowns. Gundersen and Kaltofen tapped 15 volunteer scientists to help collect the dust and soil — mostly from Fukushima Prefecture and Minamisouma City. “A majority of these samples were collected from locations in decontaminated zones cleared for habitation by the National Government of Japan,” the study revealed. For the 108 samples taken in 2016, an “International Medcom Inspector Alert surface contamination monitor (radiation survey meter) was used to identify samples from within low lying areas and on contaminated outdoor surfaces.”
A Fairewinds Associates’ video from 2012 features Gundersen collecting five samples of surface soil from random places throughout Tokyo — places including a sidewalk crack, a rooftop garden, and a previously decontaminated children’s playground. The samples were bagged, declared through Customs, and brought back to the U.S. for testing. All five samples were so radioactive that according to Gundersen, they “qualified as radioactive waste here in the United States and would have to be sent to Texas to be disposed of.” Those five examples were not included as part of the recently released study, but Gundersen went back to Tokyo for samples in 2016. Those samples were included, and were radioactive, and according to Gundersen were “similar to what I found in Tokyo in [2012].”
Furthermore, 142 of the 180 samples (about 80 percent) contained cesium 134 and cesium 137. Cesium 134 and 137, two of the most widespread byproducts of the nuclear fission process from uranium-fueled reactors, are released in large quantities in nuclear accidents. Cesium emits intense beta radiation as it decays away to other isotopes, and is very dangerous if ingested or inhaled. On a mildly positive note, the study shows that only four of the 235 dust samples tested in the United States and Canada had detectable levels of cesium from Fukushima.
Cesium, due to its molecular structure, mimics potassium once inside the body, and is often transported to the heart where it can become lodged, thereafter mutating and burning heart tissue which can lead to cardiovascular disease. Other isotopes imitate nutritive substances once inside the body as well. Strontium 90 for example mimics calcium, and is absorbed by bones and teeth.
“Different parts of the human body (nerves, bones, stomach, lung) are impacted differently,” Kaltofen told EnviroNews in an email. “Different cells have radio-sensitivities that vary over many orders of magnitude. The body reacts differently to the same dose received over a short time or a long time; the same as acute or chronic doses in chemical toxicity.”
In contrast to external X-rays, gamma, beta or alpha rays, hot particles are small mobile pieces of radioactive elements that can be breathed in, drunk or eaten in food. The fragments can then become lodged in bodily tissue where they will emanate high-intensity ionizing radiation for months or years, damaging and twisting cells, potentially causing myriad diseases and cancer. The study points out, “Contaminated environmental dusts can accumulate in indoor spaces, potentially causing radiation exposures to humans via inhalation, dermal contact, and ingestion.”
The study also explains, “Given the wide variability in hot particle sizes, activities, and occurrence; some individuals may experience a hot particle dose that is higher or lower than the dose calculated by using averaged environmental data.” For example, a person living in a contaminated area might use a leaf blower or sweep a floor containing a hefty amount of hot particle-laden dust and receive a large does in a short time, whereas other people in the same area, exposed to the same background radiation and environmental averages, may not take as heavy a hit as the housekeeper that sweeps floors for a living. People exposed to more dust on the job, or who simply have bad luck and haphazardly breathe in hot radioactive dust, are at an increased risk for cancer and disease. High winds can also randomly pick up radioactive surface soil, rendering it airborne and endangering any unsuspecting subject unlucky enough to breath it in.
Hot particles, or “internal particle emitters” as they are sometimes called, also carry unique epidemiological risks as compared to a chest X-ray by contrast. The dangers from radiation are calculated by the dose a subject receives, but the manner in which that dose is received can also play a critical factor in the amount of damage to a person’s health.
“Comparing external radiation to hot particles inside the body is an inappropriate analogy,” Gundersen told EnviroNews in an email. “Hot particles deliver a lot of energy to a very localized group of cells that surround them and can therefore cause significant localized cell damage. External radiation is diffuse. For example, the weight from a stiletto high heal shoe is the same as the weight while wearing loafers, but the high heal is damaging because its force is localized.”
Kaltofen elaborated with an analogy of his own in a followup email with EnviroNews saying:
Dose is the amount of energy in joules absorbed by tissue. Imagine Fred with a one joule gamma dose to the whole body from living in a dentist’s office over a lifetime, versus Rhonda with exactly the same dose as alpha absorbed by the lung from a hot particle. Standard health physics theory says that Fred will almost certainly be fine, but Rhonda has about a 10 percent chance of dying from lung cancer — even though the doses are the same.
External radiation and internal hot particles both follow exactly the same health physics rules, even though they cause different kinds of biological damage. Our data simply shows that you can’t understand radiation risk without measuring both.
Some isotopes, like plutonium, only pose danger to an organism inside the body. As an alpha emitter, plutonium’s rays are blocked by the skin and not strong enough to penetrate deep into bodily tissue. However, when inhaled or ingested, plutonium’s ionizing alpha rays twist and shred cells, making it one of the most carcinogenic and mutagenic substances on the planet.
“Measuring radioactive dust exposures can be like sitting by a fireplace,” Dr. Kaltofen explained in a press release. “Near the fire you get a little warm, but once in a while the fire throws off a spark that can actually burn you.”
“We weren’t trying to see just somebody’s theoretical average result,” Kaltofen continued in the press release. “We looked at how people actually encounter radioactive dust in their real lives. [By] combining microanalytical methods with traditional health physics models… we found that some people were breathing or ingesting enough radioactive dust to have a real increase in their risk of suffering a future health problem. This was especially true of children and younger people, who inhale or ingest proportionately more dust than adults.”
“Individuals in the contaminated zone, and potentially well outside of the mapped contaminated zone, may receive a dose that is higher than the mean dose calculated from average environmental data, due to inhalation or ingestion of radioactively-hot dust and soil particles,” the study says in summation. “Accurate radiation risk assessments therefore require data for hot particle exposure as well as for exposure to more uniform environmental radioactivity levels.”
Muon Scan in Fukushima Unit 3 Finds No Fuel in Reactor Vessel
On July 28 Tepco announced the unit 3 reactor muon scan preliminary results. The muon scan can detect masses of nuclear fuel if over at least a cubic meter.
Tepco declared that they will continue the muon scan, however this continued scan will certainly refine the data but not change much the results.
Tepco admitted finding no significant amount of fuel inside the unit 3 reactor vessel. These muon scans do not quantify possible fuel in the containment structure or in the base mat concrete of the building.
A recently done ROV inspection of the unit 3 containment structure, including the pedestal area below the reactor vessel, clearly located some melted fuel. However as the video and imagery published was limited and heavily edited, it is currently unclear how much fuel was found in that area.

METI Releases Map of Suitable Nuclear Waste Disposal Sites
To be clear ! No place is ‘suitable’ for storing nuke waste, never was, never will be…
Even more in Japan where you can hardly find land without an active fault beneath it, 2000 plus earthquakes per year. Not counting the volcanoes.
Japan Releases Map of Areas Suitable for Nuclear Waste Disposal
Japan released a map identifying areas of the country suitable for nuclear waste disposal as part of a broader plan to figure out what to do with roughly 18,000 tons of highly radioactive nuclear waste.
The map highlights areas that aren’t near fault lines, volcanoes or ground where temperatures are high — thus making them highly likely to be adequate for storing the so-called high-level radioactive waste consisting primarily of used fuel from nuclear facilities.
The map will be used to begin determining the ideal location to store the waste 300 meters (984 feet) underground, according to Hirokazu Kobayashi, director of radioactive waste management at Japan’s Ministry of Economy, Trade and Industry. More than 1,500 of Japan’s 1,800 municipalities have areas suitable for storing nuclear waste, he added.
The map’s release “is the first step on the long road toward disposing of the nation’s highly radioactive nuclear waste,” METI minister Hiroshige Seko told reporters in Tokyo on Friday.
Before storage, the fuel would be reprocessed at facilities designed to separate usable uranium from high-level waste. Construction of the nation’s first large-scale reprocessing plant at the Rokkasho complex in northern Japan is expected to finish in the first half of the next fiscal year.
METI maps out suitable nuclear waste disposal sites
The government on Friday unveiled a nationwide map of potential disposal sites for high-level nuclear waste that identifies coastal areas as “favorable” and those near active faults as unsuitable.
Based on the map, the government is expected to ask the municipalities involved to let researchers study whether sites on their land can host atomic waste disposal sites.
But the process promises to be both difficult and complicated as public concern lingers over the safety of nuclear power since the triple core meltdown in Fukushima Prefecture in March 2011.
The map, illustrated in four colors indicating the suitability of geological conditions, was posted on the website of the Ministry of Economy, Trade and Industry.
Energy minister Hiroshige Seko said earlier Friday that the unveiling of the map is an “important step toward bringing about final disposal sites, but also the first step on a long road.”
“We hope to communicate (with municipalities) nationwide and win over the public,” he said.
“The map is not something with which we will seek municipalities’ decisions on whether to accept a disposal site,” Seko said.
To permanently dispose of high-level nuclear waste, it must be stored at a repository more than 300 meters underground so it cannot harm human life or the environment.
The map identifies about 70 percent of Japan as suitable for hosting nuclear dumps. Up to 900 municipalities, or half of the nation’s total, encompass coastal areas deemed favorable for permanent waste storage.
Areas near active faults, volcanoes and oil fields, which are potential drilling sites, are deemed unsuitable because of “presumed unfavorable characteristics,” and hence colored in orange and silver on the map.
The other areas are classified as possessing “relatively high potential” and colored in light green.
Among the potential areas, zones that are within 20 km (12 miles) of the coastline are deemed especially favorable in terms of waste transportation and colored in green. The ministry formulated the classification standards in April.
Parts of giant Fukushima Prefecture, where decontamination and recovery efforts remain underway from the mega-quake, tsunami and triple core meltdown of March 2011, are also suitable, according to the map. But Seko said the government has no plans at this stage to impose an additional burden on the prefecture.
Seko also signaled that Aomori Prefecture, which hosts a nuclear fuel reprocessing facility, is exempt from the hunt because the prefectural government and the state have agreed not to build a nuclear waste disposal facility there.
Japan, like many other countries with nuclear power plants, is struggling to find a permanent geological site suitable for hosting a disposal repository. Finland and Sweden are the only countries worldwide to have picked final disposal sites.

Fukushima: New Study Shows Full Radiation Risks Are Not Recorded
Today, the scientific journal Science of the Total Environment (STOTEN) published a peer-reviewed article entitled: Radioactively-hot particles detected in dusts and soils from Northern Japan by combination of gamma spectrometry, autoradiography, and SEM/EDS analysis and implications in radiation risk assessment. Co-authored by Dr. Marco Kaltofen, Worcester Polytechnic Institute (WPI), and Arnie Gundersen, Fairewinds Energy Education, the article details the analysis of radioactively hot particles collected in Japan following the Fukushima Dai-ichi meltdowns.
Based on 415 samples of radioactive dust from Japan, the USA, and Canada, the study identified a statistically meaningful number of samples that were considerably more radioactive than current radiation models anticipated. If ingested, these more radioactive particles increase the risk of suffering a future health problem.
“Measuring radioactive dust exposures can be like sitting by a fireplace,” Dr. Kaltofen said. “Near the fire you get a little warm, but once in a while the fire throws off a spark that can actually burn you.”
The same level of risk exists in Japan. While most people have an average level of risk, a few people get an extra spark from a hot particle.
According to Dr. Kaltofen, “The average radiation exposures we found in Japan matched-up nicely with other researchers. We weren’t trying to see just somebody’s theoretical average result. We looked at how people actually encounter radioactive dust in their real lives. Combining microanalytical methods with traditional health physics models,” he added, “we found that some people were breathing or ingesting enough radioactive dust to have a real increase in their risk of suffering a future health problem. This was especially true of children and younger people, who inhale or ingest proportionately more dust than adults.”
Fairewinds’ book Fukushima Dai-ichi: The Truth and the Way Forward was published in Japan by Shueisha Publishing, just prior to the one-year commemoration of the tsunami and meltdowns. “Our book,” Mr. Gundersen said, “which is a step-by-step factual account of the reactor meltdowns, was a best seller in Japan and enabled us to build amazing relations with people actually living in Japan, who are the source of the samples we analyzed. We measured things like house dusts, air filters, and even car floor mats. Collecting such accurate data shows the importance of citizen science, crowd sourcing, and the necessity of open, public domain data for accurate scientific analysis.”
Fairewinds Energy Education founder Maggie Gundersen said, “We are very thankful to the scientists and citizen scientists in Japan, who sought our assistance in collecting and analyzing this data. We will continue to support ongoing scientific projects examining how people in Japan and throughout the world experience radioactive dust in their daily lives.”
The complete peer reviewed report and project audio description by Dr. Kaltofen are available here at the Science of the Total Environment website.

Soil Radioactive Contamination Measurements of Namie, Fukushima.
Some maps of the “Environmental Radioactivity Project around the Fukushima Daiichi Nuclear Power Plant” project, a measurement group of Japanese citizens based in Minamisoma, Fukushima Prefecture, are published in the blog “Fukushima 311 Voices “, https://fukushima311voices.wordpress.com/
Some maps of the “Environmental Radioactivity Project around the Fukushima Daiichi Nuclear Power Plant” project, a measurement group of Japanese citizens based in Minamisoma in Fukushima Prefecture, are published in the blog “Fukushima 311 Voices “.
This is the area in Namie-cho where the restrictions on living were recently lifted by the government (March 31, 2017).
It is the measurement result of Namie Town in the area which was evacuated, from this spring.
About 10 days from April to July, we measured the air dose rate, surface contamination count rate, and soil contamination density of 314 points, which were the approximate center points of the mesh divided into 375 m × 250 m.
But for the soil contamination density, the numerical value was less than 40,000 Bq / ㎡ (which is the designated standard of a radiation control area) at only 3 points.
Incidentally, the average of the soil contamination density is 858,143 Bq / ㎡ (maximum is 6,780,000 Bq / ㎡, the minimum is 31,400 Bq / ㎡), the average of the air dose rate at 1 m above the ground is 1.12 μSv / h, the surface contamination count rate was 1,199 cpm, which was very high.
Even the Japanese government, even radiation workers, have been given restrictions on staying time, meals, age, etc. in the areas of 40,000 Bq / ㎡ or more, but people who were to be affected by even more severely radiation-contaminated areas (including pregnant women and others) were supposed to return home.
I would like many people to know this reality. Furthermore, I would like to ask for such a great support as we share the thought of Minami-soma who are fighting in trials against such a high evacuation standard setting of 20 mSv / yr by the Japanese government.

(S/NF) Background: Over two years ago Russia requested a ten-gram sample of highly enriched uranium (HEU) seized in early 2006 in Georgia during a nuclear smuggling sting operation involving one Russian national and several Georgian accomplices. The seized HEU was transferred to U.S. custody and is being held at a secure DOE facility. In response to the Russian request, the Georgian Government authorised the United States to share a sample of the material with the Russians for forensic analysis.

Change of plan needed for Fukushima reactors cleanup, following underwater images
Footage from reactor 3 may force rewrite of Fukushima road map, officials say, http://www.japantimes.co.jp/news/2017/07/30/national/footage-reactor-3-may-force-rewrite-fukushima-road-map-officials-say/ KYODO The first images of melted fuel from the crippled Fukushima No. 1 power plant indicate that it did not burn through the pressure vessel of reactor 3, but exited through the holes used to insert the control rods, officials say.
While the landmark robot footage from the primary containment vessel of unit 3 is helping Tokyo Electric grasp the reality of the damaged fuel assemblies, it may also force it to rewrite the road map for decommissioning the meltdown-hit plant.
Tokyo Electric Power Company Holdings Inc., better known as Tepco, sent an underwater robot into reactor 3 earlier this month to confirm its hypothesis that the core — the fuel assemblies in the pressure vessel — broke apart and fell to the bottom, letting molten fuel burn through and drip into the primary containment vessel.
According to Tepco spokesman Takahiro Kimo to, however, the images taken beneath the PCV indicate the pressure vessel probably withstood the heat of the molten fuel. He said the fuel apparently seeped through the holes for the control rods.
“We do not presume that the vessel, which is 14 cm thick, melted and collapsed together with the fuel, but that part of the fuel instead made its way down through holes,” Kimoto said. The control rods are used to moderate the chain reaction and are inserted vertically into the core.
Tepco said it estimates reactor 3 has about 364 tons of fuel debris, and that similar amounts will be found in reactors 1 and 2. Removing the fuel from the reactors is the largest challenge in defueling the aged plant — a process that could take up to 40 years to complete.
The camera on the underwater robot also captured images of rubble around the fuel debris, which could slow the removal process. The rubble includes devices for supporting the control rods at the bottom of the PCV and scaffolding for maintenance workers beneath the pressure vessel.
Minister of Economy, Trade and Industry Hiroshige Seko said the government and Tepco will try to draft a plan for removing the melted fuel in September, with an eye to hammering out the specifics in the first half of fiscal 2018 and starting the work in 2021.
But the findings from reactor 3 may force them to alter the state’s road map for decommissioning Fukushima No. 1, officials said.
An entity providing technical support for the project has urged that efforts be made to remove the melted fuel from the submerged lower part of the PCV by keeping air in the upper part, according to a source familiar with the plan.
Although filling the PCV completely with water would largely reduce the radiation risk to the robot probes, the Nuclear Damage Compensation and Decommissioning Facilitation Corp. is reluctant to do so because it is damaged and the toxic water will just leak out, the source said.
At the other two reactors, Tepco thinks most of the fuel in reactor 1 fell to the bottom of the primary containment vessel, and that some of the fuel in reactor 2 remained in the pressure vessel. The company made the estimates based on cosmic ray imaging analysis and by sending robots and endoscopes into the PCVs of the two reactors.
An inconvenient Al Gore: new climate change film
Climate change: Al Gore gets inconvenient again Michael E. Mann, Nature, 27 July 2017
Michael Mann views the US statesman’s second film probing climate change.
An Inconvenient Sequel: Truth to Power
As US vice-president under Bill Clinton, Gore became the figurehead of the movement to combat human-driven global warming. He also became the preferred punchbag for climate-change cynics in search of a straw man. Gore is such a towering, seemingly unassailable figure in this arena that critics have gone after him with all guns blazing. As Tom Toles and I noted in our book The Madhouse Effect (Columbia Univ. Press, 2016; see Nature 538, 34–35; 2016): “They have criticized his weight, his energy bills, and incidents in his personal life — indeed, pretty much anything else they can scrape up.”
There’s one problem with taking on Gore. He punches back, and above his weight. After all, he’s up against arguably the most entrenched, wealthy and powerful industry the world has ever known: fossil fuels. And this pugilist is still very much in the fight. Witness his new film An Inconvenient Sequel: Truth to Power — the follow-up to his 2006 An Inconvenient Truth.
For those fearing a preachy PowerPoint lecture on climate science, be assured: An Inconvenient Sequel isn’t that. Rather, it largely takes the scientific evidence as a given, not least because Gore has already done a whole film on that. This instalment is an attempt to show us how striking climate impacts have become in the decade since his first movie.
Early in An Inconvenient Sequel, there’s a scene on the Greenland ice sheet, where glaciologists Eric Rignot and Konrad Steffen point to the dramatic retreat of ice in recent years. We witness rivers of surface melt water gushing away from the ice sheet to the open water of the North Atlantic Ocean. Gore poses the question: “Where is all of that water going?” He then answers it. We’re transported to Miami Beach, Florida, where we witness the flooding of streets that now comes simply with seasonal high tides. If melting Greenland ice seems distant and abstract, the perennial flooding of Miami and other coastal cities, and low-lying, highly populated countries from Bangladesh to Belgium is anything but.
The drought that has afflicted Syria for more than a decade is the most pronounced and prolonged for at least 900 years (as far back as we have reliable palaeodata). Climate change has undoubtedly had a role. Gore shows us how the impact of the drought on rural farmers led to increased conflict, a civil war, mass exodus, global conflict over immigration and, as a consequence, the emergence of Islamist terrorist group ISIS. If drought in Syria seems distant or even mundane, the threat of terrorism and global political instability is immediate and visceral. Gore has a genius for joining the dots in the global mapping of climate impacts.
In An Inconvenient Truth, Gore showed a version of the famous ‘hockey-stick’ curve that my co-authors and I published in the late 1990s ( et al. Geophys. Res. Lett. 26, 759–762; 1999), revealing a dramatic spike in temperature over the past century. There is a ‘hockey stick’ in the new film, but it charts instead the remarkable global growth in renewable energy over the past decade. Climate change is accelerating; so too is our ability to tackle it. There are reasons for cautious optimism……
Finally, the film casts an inconvenient light on humanity. It is astonishing that we’re still mired in a political debate about whether climate change even exists when, with each passing year of insufficient action, the challenge of averting a catastrophe becomes ever greater. Knowing that Al Gore is still optimistic is a shot in the arm at a time of uncertainty. http://www.nature.com/nature/journal/v547/n7664/full/547400a.html?foxtrotcallback=true
China now out of favour with Donald Trump
Donald Trump says China does ‘nothing’ to thwart North Korea’s nuclear quest Trump has previously used conciliatory and at times fawning language to refer to China’s President Xi, but the honeymoon appears to be over, Guardian, Tom Phillips 30 July 17, Donald Trump has launched his latest Twitter assault on China, accusing its Communist party leaders of doing “NOTHING” to help the United States thwart North Korea’s quest for nuclear weapons.
“I am very disappointed in China,” Trump wrote. “Our foolish past leaders have allowed them to make hundreds of billions of dollars a year in trade, yet … they do NOTHING for us with North Korea, just talk.
“We will no longer allow this to continue. China could easily solve this problem!” he added.
The comments came after Kim Jong-un celebrated his country’s second intercontinental ballistic missile (ICBM) test late on Friday, in what North Korean state media described as a warning to the “beast-like US imperialists”.
On Saturday, the US secretary of state, Rex Tillerson, accused Russia and China of being North Korea’s “principal economic enablers” and claimed they bore “unique and special responsibility” for its “belligerent” pursuit of nuclear weapons.
Conservative news outlets in the US appeared to relish Trump’s decision to assail Beijing for its alleged role in North Korea’s missile and nuclear programs.
“Trump rips China on Twitter,” ran a Fox News headline……..
There were reports, later, that two US B-1 bombers fly over the Korean peninsula in response to North Korea’s missile test. https://www.theguardian.com/us-news/2017/jul/30/donald-trump-says-china-does-nothing-to-thwart-north-koreas-nuclear-quest
