This morning Pieter, Xeni and I (pictured above) set out with Miles, along with father/son superteam Joe and Bryan Moross. The plan was to drop off a few Geiger counters with volunteers and try to cover some some new ground, perhaps near the exclusion zone. But it ended up being so much more.

The day began in Shinjuku around close to 7:30am when we picked up a rental car, this was a large group with a lot of gear so we had a need for two vehicles and the usual Safecast car on it’s own wasn’t quite enough. We wasted no time and started driving north. Depending on where you are in the city, background radiation levels in Tokyo hover right around 50 CPM which is only slightly higher than what we believe they were prior to 3/11 though we weren’t measuring things then so can’t be positive. For our purposes we are assuming the average around the country was 35 CPM which is worth noting before I start mentioning numbers going forward. It wasn’t too long in our trip before we hit our first hotspot in Nasu.

Our first stop was Nihonmatsu which is not too far from Koriyama to meet up with some volunteers in the area and hand out a few new sensors for them to take measurements with. We met at restaurant and of course started measuring things the moment we set foot in the parking lot. Levels were noticeably higher than we’d seen just a few hours prior in Tokyo.

The reading is also higher than levels measured recently at Iitate, an area in Fukushima prefecture that has been evacuated. The reading in Setagaya was taken one metre above the ground near a hedge, national broadcaster NHK said, while other parts of the same sidewalk showed lower readings. The reading came after ward authorities said Wednesday that levels of 2.7 microsieverts per hour had been detected on October 6, higher than levels of less than 0.1 microsieverts in other parts of Setagaya according to official data.

The higher readings come as more tests illustrate how far fall-out from the Fukushima disaster have spread, with elevated levels of radioactive caesium recently found as far away as Yokohama, more than 241 kilometers (150 miles) from the plant.

Setagaya ward did not immediately confirm Thursday's reading. "We don't know the cause (of the high radiation levels) yet. We are asking experts to find it urgently and decontaminate the area," a spokeswoman said. She added that the high readings have been shown only in a two-meter long area and below 1.5 meters from the ground. "We also plan to check sand in the ward's 258 parks over one month from late October," she told AFP. Radiation levels in the area have not fallen since the ward's efforts to decontaminate it on October 6, and authorities are instructing children to avoid the walkway as they go to school.

Scientists and doctors are calling for a new national policy in Japan that mandates the testing of food, soil, water, and the air for radioactivity still being emitted from Fukushima's heavily damaged Daiichi nuclear power plant."How much radioactive materials have been released from the plant?" asked Dr Tatsuhiko Kodama, a professor at the Research Centre for Advanced Science and Technology and Director of the University of Tokyo's Radioisotope Centre, in a July 27 speech to the Committee of Health, Labour and Welfare at Japan's House of Representatives. "The government and TEPCO have not reported the total amount of the released radioactivity yet," said Kodama, who believes things are far worse than even the recent detection of extremely high radiation levels at the plant. There is widespread concern in Japan about a general lack of government monitoring for radiation, which has caused people to begin their own independent monitoring, which are also finding disturbingly high levels of radiation. Kodama's centre, using 27 facilities to measure radiation across the country, has been closely monitoring the situation at Fukushima - and their findings are alarming.According to Dr Kodama, the total amount of radiation released over a period of more than five months from the ongoing Fukushima nuclear disaster is the equivalent to more than 29 "Hiroshima-type atomic bombs" and the amount of uranium released "is equivalent to 20" Hiroshima bombs.

Kodama, along with other scientists, is concerned about the ongoing crisis resulting from the Fukushima situation, as well as what he believes to be inadequate government reaction, and believes the government needs to begin a large-scale response in order to begin decontaminating affected areas.Distrust of the Japanese government's response to the nuclear disaster is now common among people living in the effected prefectures, and people are concerned about their health.Recent readings taken at the plant are alarming.When on August 2nd readings of 10,000 millisieverts (10 sieverts) of radioactivity per hour were detected at the plant, Japan's science ministry said that level of dose is fatal to humans, and is enough radiation to kill a person within one to two weeks after the exposure. 10,000 millisieverts (mSv) is the equivalent of approximately 100,000 chest x-rays.

t is an amount 250 per cent higher than levels recorded at the plant in March after it was heavily damaged by the earthquake and ensuing tsunami. The operator of Japan's crippled Fukushima Daiichi nuclear power plant, Tokyo Electric Power Company (TEPCO), that took the reading, used equipment to measure radiation from a distance, and was unable to ascertain the exact level because the device's maximum reading is only 10,000 mSv. TEPCO also detected 1,000 millisieverts (mSv) per hour in debris outside the plant, as well as finding 4,000 mSv per hour inside one of the reactor buildings.

Areas around the crippled Fukushima nuclear plant could remain uninhabitable for 20 years, Japan warned yesterday.The plant is still leaking low-level radiation nearly six months after the earthquake and tsunami triggered a nuclear meltdown.About 80,000 people were evacuated and many are still living in shelters.   

A ban on going within 12 miles of the plant remains in place. At a meeting with local officials yesterday, the government said it could take 20 years for residents to return to areas with higher radiation readings and a decade to return to areas with half those levels of radiation. Experts estimate the decontamination fight could cost Japan £80 billion.The Fukushima disaster released about 15 per cent of the radiation that escaped from the Chernobyl reactor in Ukraine in 1986. A vast area is still uninhabitable around the plant.

The Japanese government unveiled guidelines this week with the aim of halving radiation in problem areas in two years, but for spots with very high readings it could take much longer to reach safe levels.         'I can't deny the possibility that it could be a long time before people can return to and live in regions with high radiation levels,' outgoing Prime Minister Naoto Kan was quoted by domestic media as telling Fukushima Governor Yuhei Sato. 

In KING 5 TV's report Tuesday on high levels of radiation detected in Northwest rainwater, the United States government is accused of continuing to fail to tell the public about Fukushima dangerous radiation blanketing parts of the United States, a coverup that led grassroots projects and independent reporters to gather and present data for public well-being.

I have been rereading a 1982 book by Bertrand Goldschmidt titled “The Atomic Complex: A Worldwide Political History of Nuclear Energy.”

The two self-assigned homework projects are as part of a reflective effort to understand more about how human society moved from a period of optimism based on a vision of “Atoms for Peace” to a period where someone reading the advertiser supported press would believe that sensible people would logically consider giving up the whole technology out of fear of radiation and its health consequences.One of the hopeful lessons I have learned so far is that the initial conditions of our current fight to defend and expand the safe use of atomic energy are far different from those that faced the people engaged in the earliest battles against a well organized opposition to nuclear technology development. We have a much better chance of success now than we did then – and there are several reasons why that is true.

One condition that is vastly different is the ability of nuclear professionals to have their voices heard. No longer are most people who understand nuclear energy isolated in small communities with few media outlets. In the 1970s, a large fraction of nuclear professionals were located near remotely sited national laboratories or power stations. Today, though many still work at national labs or in small market communities like Lynchburg, VA, we are all globally connected to a vast network on the Internet. We have Skype, YouTube and blogs. Some of us know that major decision makers and journalists read or listen to our words on a regular basis. We are no longer shy about responding to misinformation and unwarranted criticism.

As blogger on nuclear energy for the past five years, I realize I’m writing on a niche subject that isn’t going to pull in millions of readers. Unlike some entertainment blogs, a site on nuclear energy is never going to be able to link the words “reactor pressure vessel” with the antics of a Hollywood celebrity at a New York night club. So, what can be said about the use of social media and how it has evolved as a new communication tool in a mature industry?

Evidence of acceptance of social media is widespread, with the most recent example being the launch of the Nuclear Information Center, a social media presence by Duke Energy (NYSE:DUK). Content written for the Nuclear Information Center by a team of the utility’s employees is clearly designed to reach out to the general public. This effort goes beyond the usual scope of a utility Web site, which includes things like how to pay your bill online, where to call when the lights go out, and so forth.

Tokyo Shinbun is a regional newspaper covering Kanto region of Japan. It has been reporting on the Fukushima accident and resultant radiation contamination in a more honest and comprehensive manner than any national newspaper. (Their only shortcoming is that their links don't seem to last for more than a week.)Their best coverage on the subject, though, is not available digitally but only in the printed version of the newspaper. But no worry, as there is always someone who transcribes the article and post it on the net for anyone to see.

In the 2nd half of the January 27 article, Tokyo Shinbun details what kind of workers are currently working at Fukushima I Nuclear Power Plant: migrant workers young (in their 20's) and not so young (in their 60's), untrained, $100 a day. Some of them cannot even read and write.

Right now, 70% of workers at the plant are migrant contract workers from all over Japan. Most of them have never worked at nuke plants before. The pay is 8000 yen to 13,000 yen [US$104 to $170] per day. Most of them are either in their 20s who are finding it difficult to land on any job, or in their 60s who have "graduated" from the previous jobs."

Vienna, Sept 14, IRNA – Non-Aligned Movement in a statement read out at the meeting of International Atomic Energy Board of Governors on Wednesday underlined countries’ indisputable right to the development, research and use of nuclear energy for peaceful purposes.

The statement read by Egyptian envoy Khaled Sham’e said that NAM believes that all countries are entitled to the peaceful use of nuclear energy without any discrimination. Therefore, no country should be deprived of nuclear development for peaceful purposes. The countries’ decisions in the nuclear field such as Iran’s policies on fuel cycle should be respected, it noted.

NAM recognizes International Atomic Energy Agency (IAEA) as the only qualified authority to verify commitment of the member states to the Safeguard Agreement and believes that it should not come under pressure in the process, the statement said. NAM considers building a region free of nuclear weapon in the Middle East as a positive step in line with the materialization of global nuclear disarmament and will extend its support to this end.

There is a computer simulation system called SPEEDI, which the national government has spent 13 billion yen to develop. If you input the amount of radiation, topography, weather, wind direction, etc., the system will calculate where the leaked radioactive materials may go.

On March 12, two hours before Reactor 1 had a hydrogen explosion, the SPEEDI simulation was carried out by Nuclear Safety Technology Center under the jurisdiction of the Ministry of Education and Science.

Radioactive radium-226 was the source of a high radiation reading in Tokyo’s Setagaya district yesterday, officials said, ruling out the possibility it may have come from the crippled Fukushima nuclear reactors. An investigation of a house near the contaminated area turned up two boxes of bottles containing radium-226, Takao Nakaya, head of the Science Ministry’s office of the radiation regulation, said by phone today. “The high readings have nothing to do with Fukushima,” Nakaya said. Investigators found the radium under the floor of the house in Tsurumaki 5-chome and readings suggested an elderly woman who had been living there until February may have been exposed to radiation 30-times safety levels, Nakaya said. The ministry is investigating where the radium came from, according to another ministry official Tomokazu Ueda.

The decommissioning process at the Fukushima No. 1 nuclear power plant faces a further obstacle after Tokyo Electric Power Co. said radiation readings in the containment vessel of the No. 2 reactor were at fatal levels on March 27. It said readings were detected as high as 72.9 sieverts per hour, which would be fatal to humans in the event of a leak. That is also enough to affect electronics in robots or other remote-controlled equipment used to probe the reactor ahead of final decommissioning. Junichi Matsumoto, acting general director of TEPCO's Nuclear Power and Plant Siting Division, said, "We believe it is the effect from the fuel (that melted) and leaked into the containment vessel. For the decommissioning operation, we will need to develop equipment that can withstand high radiation levels."

All areas of Japan should be tested to assess how radioactive the soil and water are because the winds can blow the radioactive pollution hundreds of miles from the point source at Fukushima. Under no circumstances should radioactive rubbish and debris be incinerated as this simply spreads the isotopes far and wide to re-concentrate in food and fish. All batches of food must be adequately tested for specific radioactive elements using spectrometers. No radioactive food must be sold or consumed, nor must radioactive food be diluted for sale with non-radioactive food as radioactive elements re-concentrate in various bodily organs. All water used for human consumption should be tested weekly. All fish caught off the east coast must be tested for years to come. All people, particularly children, pregnant women and women of childbearing age still living in high radiation zones should be immediately evacuated to non-radioactive areas of Japan. All people who have been exposed to radiation from Fukushima – particularly babies, children, immunosuppressed, old people and others — must be medically thoroughly and routinely examined for malignancy, bone marrow suppression, diabetes, thyroid abnormalities, heart disease, premature aging, and cataracts for the rest of their lives and appropriate treatment instituted. Leukemia will start to manifest within the next couple of years, peak at five years and solid cancers will start appearing 10 to 15 years post-accident and will continue to increase in frequency in this generation over the next 70 to 90 years. All physicians and medical care providers in Japan must read and examine Chernobyl–Consequences of the Catastrophe for People and the Environment by the New York Academy of Sciences to understand the true medical gravity of the situation they face. I also suggest with humility that doctors in particular but also politicians and the general public refer to my web page, nuclearfreeplanet.org for more information, that they listen to the interviews related to Fukushima and Chernobyl on my radio program at ifyoulovethisplanet.org and they read my book NUCLEAR POWER IS NOT THE ANSWER. The international medical community and in particular the WHO must be mobilized immediately to assist the Japanese medical profession and politicians to implement this massive task outlined above. The Japanese government must be willing to accept international advice and help. As a matter of extreme urgency Japan must request and receive international advice and help from the IAEA and the NRC in the U.S., and nuclear specialists from Canada, Europe, etc., to prevent the collapse of Fukushima Dai-ichi Unit 4 and the spent fuel pool if there was an earthquake greater than 7 on the Richter scale.As the fuel pool crashed to earth it would heat and burn causing a massive radioactive release 10 times larger than the release from Chernobyl. There is no time to spare and at the moment the world community sits passively by waiting for catastrophe to happen. The international and Japanese media must immediately start reporting the facts from Japan as outlined above. Not to do so is courting global disaster.

The impacts on the ocean of releases of radionuclides from the Fukushima Dai-ichi nuclear power plants remain unclear. However, information has been made public regarding the concentrations of radioactive isotopes of iodine and cesium in ocean water near the discharge point. These data allow us to draw some basic conclusions about the relative levels of radionuclides released which can be compared to prior ocean studies and be used to address dose consequences as discussed by Garnier-Laplace et al. in this journal.(1) The data show peak ocean discharges in early April, one month after the earthquake and a factor of 1000 decrease in the month following. Interestingly, the concentrations through the end of July remain higher than expected implying continued releases from the reactors or other contaminated sources, such as groundwater or coastal sediments. By July, levels of 137Cs are still more than 10 000 times higher than levels measured in 2010 in the coastal waters off Japan. Although some radionuclides are significantly elevated, dose calculations suggest minimal impact on marine biota or humans due to direct exposure in surrounding ocean waters, though considerations for biological uptake and consumption of seafood are discussed and further study is warranted.

there was no large explosive release of core reactor material, so most of the isotopes reported to have spread thus far via atmospheric fallout are primarily the radioactive gases plus fission products such as cesium, which are volatilized at the high temperatures in the reactor core, or during explosions and fires. However, some nonvolatile activation products and fuel rod materials may have been released when the corrosive brines and acidic waters used to cool the reactors interacted with the ruptured fuel rods, carrying radioactive materials into the ground and ocean. The full magnitude of the release has not been well documented, nor is there data on many of the possible isotopes released, but we do have significant information on the concentration of several isotopes of Cs and I in the ocean near the release point which have been publically available since shortly after the accident started.

We present a comparison of selected data made publicly available from a Japanese company and agencies and compare these to prior published radionuclide concentrations in the oceans. The primary sources included TEPCO (Tokyo Electric Power Company), which reported data in regular press releases(3) and are compiled here (Supporting Information Table S1). These TEPCO data were obtained by initially sampling 500 mL surface ocean water from shore and direct counting on high-purity germanium gamma detectors for 15 min at laboratories at the Fukushima Dai-ni NPPs. They reported initially results for 131I (t1/2 = 8.02 days), 134Cs (t1/2 = 2.065 years) and 137Cs (t1/2 = 30.07 years). Data from MEXT (Ministry of Education, Culture, Sports, Science and Technology—Japan) were also released on a public Web site(4) and are based on similar direct counting methods. In general MEXT data were obtained by sampling 2000 mL seawater and direct counting on high-purity germanium gamma detectors for 1 h in a 2 L Marinelli beaker at laboratories in the Japan Atomic Energy Agency. The detection limit of 137Cs measurements are about 20 000 Bq m–3 for TEPCO data and 10 000 Bq m–3 for MEXT data, respectively. These measurements were conducted based on a guideline described by MEXT.(5) Both sources are considered reliable given the common activity ratios and prior studies and expertise evident by several Japanese groups involved in making these measurements. The purpose of these early monitoring activities was out of concern for immediate health effects, and thus were often reported relative to statutory limits adopted by Japanese authorities, and thus not in concentration units (reported as scaling factors above “normal”). Here we convert values from both sources to radionuclide activity units common to prior ocean studies of fallout in the ocean (Bq m–3) for ease of comparison to previously published data.
