  • The operator of the Fukushima Daiichi nuclear power plant says it will extract air from troubled reactors at the plant to measure the amount of radioactive substances. [...] The operation is intended to obtain accurate data on what kind of radioactive substances are being released and in what quantity. The air extraction is expected to begin later on Friday for the No.1 reactor and in early August for the No.2 unit. No plans have been decided for the No.3 reactor due to high radiation levels in part of its building.
  • that TEPCO doesn’t know where the melted fuel is or the actual level of radioactive particles still being released: TEPCO hopes the findings may also help the company grasp the extent of leakage of nuclear fuels into the containment vessels. Up to around one billion becquerels of radioactive substances arebelieved to be released every hour from reactors No.1, 2 and 3. It isnot known how accurate this figure is because it was worked out bytaking readings of the air on the plant’s premises.

"My university is annoyed with me" - Air filter from Japan so radioactive, it must be b... - 0 views

  • A professional video of Marco Kaltofen’s presentation to the American Public Health Association was recently made available to Fairewinds. Kaltofen states that hot particles are contaminating portions of northern Japan. He also states that auto air filters from Fukushima, that he tested in his Massachusetts laboratory, are so radioactive that they have to be disposed of in a buried radioactive waste disposal site in the US. Additionally, he expresses concerns for the mechanics who work on cars in Fukushima Prefecture.
  • At 12:30 in And also we have Fukushima’s which is about 65 kilometers away from the site. This automobile air filter is actually hazardous. My university is annoyed with me because we have to contract to have this filter disposed of as radioactive waste. Unfortunately, you can just imagine what this means to the people in Fukushima City which is not evacuated, and even for the (automobile) mechanics who are changing these air filters.

RADIOACTIVE Los Angeles AIR [16Nov11] - 0 views

  • Disturbing readings from one of Radiation Station Central's HEPA filters after just 30 days of use: 308% of normal background higher. Alpha and beta radiation captured by the filter can be attributed to the triple Fukushima Japan meltdowns, melt-throughs and melt-outs and the decision to begin burning 550,000 tons of radioactive debris in Tokyo from October to March, sending a double dose of radioactive fallout on the Jet Stream over the Pacific to land on America, Canada and beyond. Finding this high a level of radiation is considered dangerous by the United States Environmental Protection Agency. Ingested alpha particles can be up to 1,000 times more dangerous than their beta and gamma counterparts.

#Fukushima I Melted Fuel Probably No Longer in Containment Vessel Reactor 2 [09Aug11] - 0 views

  • Half life of xenon-131m is about 12 days. The measurement of density of radioactive materials in the air inside the Reactor 2 Containment Vessel was delayed because there was water in the temporary sampling instrument that TEPCO installed outside the CV. It looks like they decided to measure the water anyway, as well as the air. According to the measurement, the air is more radioactive than the water inside the Containment Vessel, but less radioactive than the air inside the Reactor 1 CV.
  • So the melted fuel is probably not even inside the Containment Vessel in Reactor 2 either. But what's with krypton and xenon? I also read a tweet by one of the workers at the plant who said there is still radioactive iodine being released, even though TEPCO's monitoring says iodine-131 is not detected at the plant any more. From TEPCO's handout for the press on August 10:

Build baby build - new nuclear power plants[25Jul11] - 0 views

  • CBS News aired a short piece titled US heat wave causes new look at nuclear energy that is worth a look. Though it includes the obligatory appearance of a professional antinuclear activist – in this case, Dr. Edwin Lyman of the Union of Concerned Scientists – the story provides some encouraging clips of the massive quantities of dirt being moved by thousands of workers who are making preparations for Vogtle Units 3 and 4 in eastern Georgia.
  • The story also reminds people why some of us are so interested in building new nuclear power plants – we know how vital reliable electricity is. That knowledge is reinforced when power grids are stressed and when people die due to complications associated with heat exposure. We know that nuclear plants have a far better chance of being available when needed than the wind turbines that were AWOL during the heat wave because, darn it, when the heat domes hover, the air is still and muggy. If there was a reliable breeze we would not be so dependent on our air conditioners!
  • a comment that I provided to CBS regarding their story:Nuclear power plants have proven that they are safe neighbors. In more than 50 years of commercial operation, the total number of deaths from exposure to radiation from nuclear power plants around the entire world is less than 100. In contrast, thousands of people die every year from exposure to the hazardous waste products that fossil fuel plants dump into our atmosphere as a routine part of their operation.I like having the ability to use electricity on demand. I like having clean air. I like the idea that building new nuclear plants that can operate reliably for 60-80 years is resulting in new jobs for thousands of American mechanics, electricians, construction workers, engineers and procedure writers. (Disclosure: I fall into that last category and am currently part of a large team that is designing another version of a reactor that can keep itself under control for at least three days without any sources of electricity.)

  • Dr. Lyman is a professional antinuclear activist who has never actually operated a plant. He has a PhD in nuclear physics, but that does not mean that he ever studied anything about engineering or operations. It might not even mean that he studied anything about nuclear fuel.

How I spent my Sunday in Fukushima » Safecast [08Aug11] - 0 views

  • 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.
  • ...14 more annotations...
  • Another bit worth noting here in case you haven’t been following along with the work Safecast has been doing so far, surface contamination is much higher than air contamination. There are two main reasons for this – “Fallout” literally means this radioactive crap fell out of the sky and found it’s new home on the ground, and much of contents of said crap are beta emitters. Beta radiation is lower energy than gamma so you need to get close to it to measure it – which in this case is the ground. If you only measure the air you miss the betas all together. Anyway. Surface is higher than air, and around 3000 CPM on the ground in the parking lot here is 10X the air levels. As occasionally happens when we are measuring out in public, people approach us to find out what we’re doing.
  • People are curious, and often they are concerned. Hiroko Ouchi was both. On top of that she was upset. She said that she hasn’t been able to get any information about the levels around them, the levels they are living in from the government or TEPCO. She said at first she wasn’t concerned because residents were told everything was fine and not to worry, but over time people started taking readings on their own and hearing about readings taken by others that suggested things weren’t all fine and this really stressed her out. This area is far enough away from the plant that no one is being officially evacuated, which means anyone who wants to leave has to do it on their own and pay for it themselves. This has caused a lot of trauma in the community as some people leave and some people stay. Ouchi-san said it is very upsetting for people to be in this position and have their questions go unanswered.
  • Once back in the car we decided to head east and see how close we could get to the exclusion zone. We watched the readings rise and fall, though generally increase on the whole the further we went. We have a device outside of the car, and several inside taking readings. At many points we would see a 25% increase depending on which side of the car we pointed a device towards. Very quick changes in very small areas here. At one point things seemed to be increasing very rapidly and at much higher jumps than we’d seen previously. We were so distracted by the drastic readings that we almost ran right into a roadblock staffed by several police officers who were standing around in the street. We turned past them and drove down the road a short ways and then stopped to look at our devices which were completely blowing up.
  • On my last transatlantic flight I measured over 800 CPM on the flight. Seeing over 1000 CPM in the car was a bit shocking, opening the door and putting the device on the ground in the middle of the street and seeing it climb, in a matter of seconds, to almost 16,000 CPM was, well, I still don’t even know how to describe it. I was completely taken aback by this. We were maybe one city block from where the officers were standing – outside and unprotected and decided we needed to go back and talk to them.
  • We measure radiation all the time, and were noticeably shaken after seeing the readings we just had, and these guys were being told there was nothing to worry about. Suddenly some sort of commanding officer arrived and told us we had to leave and everyone stopped talking to us. Like turning off a switch.
  • The officers were very polite and happy to talk to us. We asked them if they were concerned that they were standing outside all day with no protective gear and they told us their bosses have assured them it is perfectly safe and so they have to trust them. We told them about the readings we’d taken just steps from where they were and offered to show them personally that the levels were incredibly high – they declined saying they needed to trust the authorities. Which was weird, because to most people – they are the authorities
  • We got back in the car and drove about 1km away the other direction away from the roadblock.
  • There was a small restaurant that was closed up and seemed like a good place to stop, take some measurements and talk about what had just happened
  • This restaurant had signs taped in the window saying basically “Sorry we are closed for an undetermined period of time. Will try to reopen in the spring.”
  • It was here that we took our highest and most concerning readings of the day. The parking lot of the restaurant was active, but less than we’d just seen. But when we walked across the street – maybe 10 feet away, we measured over 20,000 CPM and 9 µSv/hr. We pulled out our SAM 940 to try and identify the isotopes and found things we weren’t expecting at all. So we grabbed some samples to send to a lab for professional analysis and got out of there quick.
  • As we were starting to wrap up a car drove by and came to a quick stop. Two gentlemen got out, one of them was a reporter for Asahi TV and the other was Tadao Mumakata, a resident of Koroyama who is working on a way to produce geiger counters locally. They knew about Safecast and were excited to run into us. We talked for a while and then decided to go get some food before heading back to Tokyo. We stopped at a smallish family restaurant and talked about our plans and goals, geiger counts and what we’d learned – hoping to pass some of this on and hopefully help someone skip over some of the early mistakes we’d made ourselves. They were happy for the info and we exchanged contacts for further discussion.
  • around 2:30 am we made it back and started dropping people off at their respective houses/hotels. But no spare moment could be wasted. At the final stop we uploaded the log files from the bGeigie – the geiger counter we had mounted outside of the car all day logging radiation and mapping it against GPS points. This produces a map of the whole drive, and dumps the data into our full database, filling in a few more pieces of the big picture.
  • And it really is a big picture. These places have never had the kinds of detailed measurements we’re taking, and the measurements that have happened haven’t been shared openly with the residents – who without question are the ones who need to have that info the most. I’ve known this since we started the project but seeing it first hand today and hearing people thank us for trying and for caring was heavy. This project is important and I’m so honored to be a part of it, and so glad to have others involved who have done the impossible to get us this far already.
  • Please contact Japan cat network (www.japancatnet.com)( my friends David/Susan) and /or JEARS (Japan earthquake animal rescue) on FB as they are doing great work in that evacuated area and perhaps would be interested in a collaborative effort to get data and ensure animal safety.

The Environmental Case for Nuclear Energy - Korea [26Sep11] - 0 views

  • Six months after the Fukushima disaster, the repercussions of history’s second-largest nuclear meltdown are still being felt, not only in Japan but around the world. Predictably, people are rethinking the wisdom of relying on nuclear power. The German and Swiss governments have pledged to phase out the use of nuclear power, and Italy has shelved plans to build new reactors. Public debate on future nuclear energy use continues in the United Kingdom, Japan, Finland, and other countries.So far, it is unclear what the reaction of the Korean government will be. Certainly, the public backlash to nuclear energy that has occurred elsewhere in the world is also evident in Korea; according to one study, opposition to nuclear energy in Korea has tripled since the Fukushima disaster. However, there are countervailing considerations here as well, which have caused policy-makers to move cautiously. Korea’s economy is often seen as particularly reliant on the use of nuclear power due to its lack of fossil fuel resources, while Korean companies are some of the world’s most important builders (and exporters) of nuclear power stations.
  • There are three primary reasons why nuclear power is safer and greener than power generated using conventional fossil fuels. First ― and most importantly ― nuclear power does not directly result in the emission of greenhouse gases. Even when you take a life-cycle approach and factor in the greenhouse gas emissions from the construction of the plant, there is no contest. Fossil fuels ― whether coal, oil, or natural gas ― create far more global warming.
  • The negative effects of climate change will vastly outweigh the human and environmental consequences of even a thousand Fukushimas. This is not the place to survey all the dire warnings that have been coming out of the scientific community; suffice it to quote U.N. Secretary General Ban Ki-moon’s concise statement that climate change is the world’s “only one truly existential threat … the great moral imperative of our era.” A warming earth will not only lead to death and displacement in far-off locales, either. Typhoons are already hitting the peninsula with greater intensity due to the warming air, and a recent study warns that global warming will cause Korea to see greatly increased rates of contagious diseases such as cholera and bacillary dysentery.
  • ...5 more annotations...
  • As the world’s ninth largest emitter of greenhouse gases, it should be (and is) a major priority for Korea to reduce emissions, and realistically that can only be accomplished by increasing the use of nuclear power. As Barack Obama noted with regard to the United States’ energy consumption, “Nuclear energy remains our largest source of fuel that produces no carbon emissions. It’s that simple. (One plant) will cut carbon pollution by 16 million tons each year when compared to a similar coal plant. That’s like taking 3.5 million cars off the road.” Environmentalists have traditionally disdained nuclear power, but even green activists cannot argue with that logic, and increasing numbers of them ― Patrick Moore, James Lovelock, Stewart Brand and the late Bishop Hugh Montefiore being prominent examples ― have become supporters of the smart use of nuclear power.
  • Second, the immediate dangers to human health of conventional air pollution outweigh the dangers of nuclear radiation. In 2009, the Seoul Metropolitan Government measured an average PM10 (particulate) concentration in the city of 53.8 g/m3, a figure that is roughly twice the level in other developed nations. According to the Gyeonggi Research Institute, PM10 pollution leads to 10,000 premature deaths per year in and around Seoul, while the Korea Economic Institute has estimated its social cost at 10 trillion won. While sulfur dioxide levels in the region have decreased significantly since the 1980s, the concentration of nitrogen dioxide in the air has not decreased, and ground-level ozone levels remain high. Unlike fossil fuels, nuclear power does not result in the release of any of these dangerous pollutants that fill the skies around Seoul, creating health hazards that are no less serious for often going unnoticed.
  • And third, the environmental and safety consequences of extracting and transporting fossil fuels are far greater than those involved with the production of nuclear power. Korea is one of the largest importers of Indonesian coal for use in power plants, for example. This coal is not always mined with a high level of environmental and safety protections, with a predictable result of air, water, and land pollution in one of Asia’s most biologically sensitive ecosystems. Coal mining is also one of the world’s more dangerous occupations, as evidenced by the many tragic disasters involving poorly managed Chinese mines. While natural gas is certainly a better option than coal, its distribution too can be problematic, whether by ship or through the recently proposed pipeline that would slice down through Siberia and North Korea to provide direct access to Russian gas.
  • What about truly green renewable energy, some might ask ― solar, wind, geothermal, hydroelectric, and tidal energy? Of course, Korea would be a safer and more sustainable place if these clean renewable resources were able to cover the country’s energy needs. However, the country is not particularly well suited for hydroelectric projects, while the other forms of renewable energy production are expensive, and are unfortunately likely to remain so for the foreseeable future. The fact is that most Koreans will not want to pay the significantly higher energy prices that would result from the widespread use of clean renewables, and in a democratic society, the government is unlikely to force them to do so. Thus, we are left with two realistic options: fossil fuels or nuclear. From an environmental perspective, it would truly be a disaster to abandon the latter.

  • Yokohama, Oct. 15 — Mochizuki of the Fukushima Diary website is reporting on a June 2011 document that has been “leaked on the internet” which reveals that Plutonium-238, -239, -240, and -241 were released “to the air” from Fukushima Daiichi during the first 100 hours after the earthquake. The amount of plutonium released is said to be 120 billion Becquerels. It also states there was a release of 7.6 trillion Becquerels of Neptunium-239. Mochizuki says this report was made by Tepco for a press conference on June 6 and the media knew and “kept concealing the risk for 7 months and kept people exposed”.

Ministry of Education's Quick Learning Curve on Kashiwa's Radioactive Dirt [23Oct11] - 0 views

  • First it was "it cannot be from Fukushima I Nuke Plant" when the radiation measured was 57.5 microsieverts/hour.Then it was "it may be from Fukushima I Nuke Plant, and it may not be" when the density turned out to be 276,000 becquerels/kg of radioactive cesium. But since the density was very high, the suspicion was voiced all around (including me) that someone secretly dumped the radioactive sludge or dirt, possibly from cleaning out his yard, onto that location.The Ministry's current position: "It is highly likely that radioactive cesium is from Fukushima I Nuke Plant, and radioactive cesium has been condensed at that particular location because the storm drain nearby was broken."So radioactive cesium from Fukushima I Nuke Plant has been naturally concentrated by elements, 200 kilometers away from the plant, to the density level on par with those found in Fukushima. The Kashiwa City's dirt contains almost as much radioactive cesium in the dirt in the location in Watari District (link is in Japanese) in Fukushima City where 300,000 becquerels/kg of radioactive cesium was found (also near the drain).
  • Points from the Ministry's announcement on October 23, 2011 "Result of the investigation of Kashiwa City's location with high air radiation" (my translation, not the Ministry's):On receiving the result of the soil analysis on October 22 where maximum 276,000 becquerels/kg of radioactive cesium was detected, the Ministry sent two officials, along with three experts from Japan Atomic Energy Agency on October 23 to Kashiwa City to consult with the local officials in charge of radiation countermeasures.The Ministry's survey of the location included measuring air radiation levels at the location and nearby, and investigating the surroundings to figure out what caused the high radiation level.Survey result:Maximum 2.0 microsieverts/hour 1 meter off the groundMaximum 4.5 microsieverts/hour 50 centimeter off the groundMaximum 15 microsieverts/hour on the ground
  • Typical air radiation levels in the surrounding area at 1 meter off the ground was 0.3 microsievert/hour.A 50-centimeter wide breach was found in the side drain (30-centimeter deep) next to the location with the high air radiation. This breach was close to the spot where cesium-134 (half life 2 years) was detected. We therefore presume that the rainwater containing radioactive cesium that came from the Fukushima I Nuclear Power Plant accident flowed in from the breach in the side drain, and radioactive cesium was condensed and accumulated in the soil at that particular location.Asahi Shinbun (10/23/2011) has the picture of the broken side drain.

Fukushima Update: Why We Should (Still) Be Worried [20Jan12] - 0 views

  • you would think the Japanese government would be doing everything in its power to contain the disaster. You would be wrong—dead wrong.
  • nstead of collecting, isolating, and guarding the millions of tons of radioactive rubble that resulted from the chain reaction of the 9.0 earthquake, the subsequent 45- to 50-foot wall of water that swamped the plant and disabled the cooling systems for the reactors, and the ensuing meltdowns, Japanese Environment Minister Goshi Hosono says that the entire country must share Fukushima’s plight by accepting debris from the disaster.
  • an estimated 20 million tons of wreckage on the land, much of which—now ten months after the start of the disaster—is festering in stinking piles throughout the stricken region. (Up to 20 million more tons of rubble from the disaster—estimated to cover an area approximately the size of California—is also circulating in the Pacific.)
  • ...9 more annotations...
  • the sheer amount of radioactive rubble is proving difficult to process. The municipal government of Kashiwa, in Chiba Prefecture to the west and south of Tokyo, recently shut down one of its main incinerators, because it can’t store any more than the 200 metric tons of radioactive ash it already has that is too contaminated to bury in a landfill.
  • According to the California-based Fukushima Fallout Awareness Network (FFAN), burning Fukushima’s radioactive rubble is the worst possible way to deal with the problem. That’s because incinerating it releases much more radioactivity into the air, not only magnifying the contamination all over Japan but also sending it up into the jet stream. Once in the jet stream, the radioactive particles travel across the Northern Hemisphere, coming back down to earth with rain, snow, or other precipitation.
  • Radiation used to be a word that evoked serious concern in a lot of people. However, the nuclear industry and its supporters have done a masterful job in allaying public fears about it. They do this in significant part by relying on outdated and highly questionable data collected on Japanese atom bomb survivors, while at the same time ignoring and dismissing inconvenient but much more relevant evidence that shows the actual harmful effects of radiation exposure from nuclear accidents. Author Gayle Greene explains this well in a recent article here. In their attempt to win the public over to their viewpoint, nuclear proponents even trot out the dubious theory of radiation hormesis, which says that low doses of radiation are actually good for you, because they stimulate an immune response. Well, so does something that causes an allergic reaction. But I digress…
  • “Plutonium is biologically and chemically attracted to bone as is the naturally occurring radioactive chemical radium. However, plutonium clumps on the surface of bone, delivering a concentrated dose of alpha radiation to surrounding cells, whereas radium diffuses homogeneously in bone and thus has a lesser localized cell damage effect. This makes plutonium, because of the concentration, much more biologically toxic than a comparable amount of radium.”
  • different radioisotopes give off different kinds of radiation—alpha, beta, gamma, X ray, or neutron emissions—all of which behave differently. Alpha emitters, such as plutonium and radon, are intensely ionizing but don’t penetrate very far and generally can’t get through the dead layers of cells covering skin. But when they are inhaled from the air or ingested from radiation-contaminated food or water, they emit high-energy particles that can do serious damage to the cells of sensitive internal soft tissues and organs. The lighter, faster-moving beta particles can penetrate far more deeply than alpha particles, though sheets of metal and heavy clothing can block them. Beta particles are also very dangerous when inhaled or ingested. Strontium-90 and tritium, a radioactive form of hydrogen, are both beta emitters. Gamma radiation is a form of electromagnetic energy like X rays, and it passes through clothing and skin straight into the body. A one-inch shield of either lead or iron, or eight inches of concrete are needed to stop gamma rays, examples of which include cobalt-60 and cesium-137—one of the radionuclides of most concern in the Fukushima fallout
  • The behavior of radioisotopes out in the environment also varies depending on what they encounter. They can combine with one another or with stable chemicals to form molecules that may or may not dissolve in water. They can combine with solids, liquids, or gases at ordinary temperature and pressure. They may be able to enter into biochemical reactions, or they may be biologically inert.
  • In her book No Immediate Danger: Prognosis for a Radioactive Earth, Bertell notes that if they enter the body either through air, food, water, or an open wound, “They may remain near the place of entry into the body or travel in the bloodstream or lymph fluid. They can be incorporated into the tissue or bone. They may remain in the body for minutes or hours or a lifetime.”
  • radioactive elements, also known as radioisotopes or radionuclides, are unstable atoms. They seek stability by giving off particles and energy—ionizing radiation—until the radioisotope becomes stable. This process occurs within the nucleus of the radioisotope, and the shedding of these particles and energy is commonly referred to as ‘‘nuclear disintegration.’’ Nuclear radiation expert Rosalie Bertell describes the release of energy in each disintegration as ‘‘an explosion on the microscopic level.” This process is known as the “decay chain,” and during their decay, most radioactive elements morph into yet other radioactive elements on their journey to becoming lighter, stable atoms at the end of the chain. Some of the morphed-into elements are much more dangerous than the original radioisotope, and the decay chain can take a very long time. This is the reason that radioactive contamination can last so long
  • the EPA was so confident that Fukushima fallout would not be a problem for U.S. citizens that it stopped its specific monitoring of fallout from Fukushima less than two months after the meltdowns began. But neglecting to monitor the fallout will not make it go away. In fact, another enormous problem with radioactive contamination is that it bioaccumulates in the environment, which means it concentrates as it moves up the food chain.

#Radioactive Compost Has Already Spread Wide [27Jul11] - 0 views

  • From the press release by Akita prefectural government on July 25:A resident in Akita Prefecture alerted the authorities when the bag of leaf compost that he purchased from a local garden/home center measured high in radiation with his portable survey meter. The authorities tested the content of the bag, and it had 11,000 becquerels/kg of cesium.
  • At the garden/home center (2 locations) the air radiation 1 meter from the pile of the leaf compost bags measured as high as 0.48 microsievert/hr.
  • The press release is somewhat misleading, as it says the air radiation 1 meter from one bag of the leaf compost is 0.06 microsievert/hr. If you measure in front of the pile of the same bags, the radiation is as high as 0.48 microsievert/hr. Akita's air radiation level (which the prefectural government measures only at 2 locations) is between 0.04 and 0.06 microsievert/hr.According to Yomiuri Shinbun (7/27/2011), these bags were packed in Tochigi Prefecture, and 20,000 bags have already been sold in Akita Prefecture alone.

  • Shimotsuke Shinbun (local Tochigi paper; 7/27/2011) reports that Tochigi Prefecture tested the leaves that went into the leaf compost bags, and they found 72,000 becquerels/kg of radioactive cesium. The leaves were collected in the northern Tochigi in April, and was sold outside the prefecture from mid June to early July. The Tochigi prefectural government ordered the two sellers of leaf compost in Tochigi to recall what's been sold and refrain from shipping "voluntarily" (i.e. at the sellers' own cost, with no support from the government).Leaf composts are mainly used by the home gardeners. There may be many who hoped to grow their own, radiation-free vegetables and bought these bags to amend the soil for better growth of the seedlings. Well, that hope is dashed. The home gardeners may have ended up contaminating their own soil which may not have been contaminated before they put in the compost.
  • The Ministry of Agriculture, Forestry and Fisheries couldn't even figure out that cattle farmers feed their cows with rice hay. What the individual home gardeners use for their small gardens was probably none of their concern, as the Ministry is there for the producers.
  •  
    By allowing contamination to spread to the entire island, if not the country, epidemiological studies of the impact on health in the medium and long-term will be made impossible, as there will be no "control" group with which to compare that has not been exposed. The risk, of course, is to the export economy as eventually export products will become contaminated also and international trade with Japan may suffer. Who is going to buy a Japanese car, if they think it is likely to glow in the dark (for example)? And radioactive electronics will show higher failure rates. - comment from reader

Canada: Japan's Fukushima Catastrophe Brings Big Radiation Spikes to B.C. [04Aug11] - 0 views

  • After Japan's Fukushima catastrophe, Canadian government officials reassured jittery Canadians that the radioactive plume billowing from the destroyed nuclear reactors posed zero health risks in this country.
  • In fact, there was reason to worry. Health Canada detected massive amounts of radioactive material from Fukushima in Canadian air in March and April at monitoring stations across the country.
  • For 22 days, a Health Canada monitoring station in Sidney detected iodine-131 levels in the air that were 61 percent above the government's allowable limit. In Resolute Bay, Nunavut, the levels were 3.5 times the limit.
  • ...4 more annotations...
  • Meanwhile, government officials claimed there was nothing to worry about. "The quantities of radioactive materials reaching Canada as a result of the Japanese nuclear incident are very small and do not pose any health risk to Canadians," Health Canada says on its website. "The very slight increases in radiation across the country have been smaller than the normal day-to-day fluctuations from background radiation." In fact, Health Canada's own data shows this isn't true. The iodine-131 level in the air in Sidney peaked at 3.6 millibecquerels per cubic metre on March 20. That's more than 300 times higher than the background level, which is 0.01 or fewer millibecquerels per cubic metre.
  • "There have been massive radiation spikes in Canada because of Fukushima," said Gordon Edwards, president of the Canadian Coalition for Nuclear Responsibility. "The authorities don't want people to have an understanding of this. The government of Canada tends to pooh-pooh the dangers of nuclear power because it is a promoter of nuclear energy and uranium sales."
  • Edwards has advised the federal auditor-general's office and the Ontario government on nuclear-power issues and is a math professor at Montreal's Vanier College.
  • It's not the risk to an individual that's the problem but how much society is at risk. When you are exposing millions of people to an insult, even if the average dose is quite small, we are going to see fatal health effects," he said.

Nevada Nuclear Test Site Operation Continuation [29Jul11] - 0 views

  • SUMMARY: The National Nuclear Security Administration (NNSA), a separately organized semi-autonomous agency within the U.S. Department of Energy (DOE), announces the availability of the Draft Site-Wide Environmental Impact Statement for the Continued Operation of the Department of Energy/National Nuclear Security Administration Nevada National Security Site and Off-Site Locations in the State of Nevada (Draft SWEIS, DOE/EIS-0426D) for public review, as well as the locations, dates and times for public hearings. The Draft SWEIS for the continued management and operation of the Nevada National Security Site (NNSS) (formerly known as the Nevada Test Site) and other NNSA-managed sites in Nevada, including the Remote Sensing Laboratory (RSL) on Nellis Air Force Base, the North Las Vegas Facility (NLVF), and the Tonopah Test Range (TTR) on the U.S. Air Force Nevada Test and Training Range, analyzes the potential environmental impacts for three alternatives: No Action Alternative, Expanded Operations Alternative and Reduced Operations Alternative. Each alternative comprises current and reasonably foreseeable activities at the NNSS and the three offsite locations.
  • The Council on Environmental Quality's (CEQ) National Environmental Policy Act (NEPA) implementing regulations allow an agency to identify its preferred alternative or alternatives, if one or more exists, in a draft EIS (40 CFR 1502.14[e]). NNSA has not currently identified a preferred alternative; however, a preferred alternative will be identified in the Final SWEIS. The U.S. Air Force, U.S. Bureau of Land Management, and Nye County, Nevada, are cooperating agencies in the preparation of this Draft SWEIS. In addition, the Consolidated Group of Tribes and Organizations, which include representatives from 17 Tribes and organizations, participated in its preparation.
  • DATES: NNSA invites comments on the Draft SWEIS during the public comment period which ends October 27, 2011. NNSA will consider comments received after this date to the extent practicable as it prepares the Final SWEIS. NNSA will hold five public hearings on the Draft SWEIS. Locations, dates and times are provided in the SUPPLEMENTARY INFORMATION portion of this notice under ``Public Hearings and Invitation To Comment'

The Intermittency of Fossil Fuels & Nuclear [19Aug11] - 0 views

  • You’ve likely heard this argument before: “The wind doesn’t always blow and the sun doesn’t always shine, so we can’t rely on renewable energy.” However, a series of recent events undermine the false dichotomy that renewable energies are unreliable and that coal, nuclear and natural gas are reliable.
  • There are too many reasons to list in a single blogpost why depending on fossil and nuclear energies is dangerous, but one emerging trend is that coal, natural gas and even nuclear energy are not as reliable as they are touted to be. Take for instance the nuclear disaster still unfolding in Japan. On March 11, that country experienced a massive earthquake and the resulting tsunami knocked out several nuclear reactors on the coast. Three days later, an operator of a nearby wind farm in Japan restarted its turbines - turbines that were intentionally turned off  immediately after the earthquake. Several countries, including France and Germany, are now considering complete phase-outs of nuclear energy in favor of offshore wind energy in the aftermath of the Japanese disaster. Even China has suspended its nuclear reactor plans while more offshore wind farms are being planned off that country’s coast.
  • In another example much closer to home, here in the Southeast, some of TVA’s nuclear fleet is operating at lower levels due to extreme temperatures. When the water temperatures in the Tennessee River reach more than 90 degrees, the TVA Browns Ferry nuclear reactors cannot discharge the already-heated power plant water into the river. If water temperatures become too high in a natural body of water, like a river, the ecosystem can be damaged and fish kills may occur. This problem isn’t limited to nuclear power plants either.

  • Texas has been experiencing a terrible heat wave this summer - along with much of the rest of the country. According to the Dallas Morning News, this heat wave has caused more than 20 power plants to shut down, including coal and natural gas plants. On the other hand, Texan wind farms have been providing a steady, significant supply of electricity during the heat wave, in part because wind farms require no water to generate electricity. The American Wind Energy Association (AWEA) noted on their blog: “Wind plants are keeping the lights on and the air conditioners running for hundreds of thousands of homes in Texas.”
  • This near-threat of a blackout is not a one-time or seasonal ordeal for Texans. Earlier this year, when winter storms were hammering the Lone Star State, rolling blackouts occurred due to faltering fossil fuel plants. In February, 50 power plants failed and wind energy helped pick up the slack.
  • Although far from the steady winds of the Great Plains, Cape Wind Associates noted that if their offshore wind farm was already operational, the turbines would have been able to harness the power of the heat wave oppressing the Northeast, mostly at full capacity. Cape Wind, vying to be the nation’s first offshore wind farm, has a meteorological tower stationed off Nantucket Sound in Massachusetts. If Cape Wind had been built, it could have been using these oppressive heat waves to operate New England’s cooling air conditioners. These three examples would suggest that the reliability of fossil fuels and nuclear reactors has been overstated, as has the variability of wind.
  • So just how much electricity can wind energy realistically supply as a portion of the nation’s energy? A very thorough report completed by the U.S. Department of Energy in 2008 (completed during President George W. Bush’s tenure) presents one scenario where wind energy could provide 20% of the U.S.’s electrical power by 2030. To achieve this level, the U.S. Department of Energy estimates energy costs would increase only 50 cents per month per household. A more recent study, the Eastern Wind Integration and Transmission Study (EWITS), shows that wind could supply 30% of the Eastern Interconnect’s service area (all of the Eastern U.S. from Nebraska eastward) with the proper transmission upgrades. As wind farms become more spread out across the country, and are better connected to each other via transmission lines, the variability of wind energy further decreases. If the wind isn’t blowing in Nebraska, it may be blowing in North Carolina, or off the coast of Georgia and the electricity generated in any state can then be transported across the continent. A plan has been hatched in the European Union to acquire 50% of those member states’ electricity from wind energy by 2050 - mostly from offshore wind farms, spread around the continent and heavily connected with transmission lines.
  • With a significant amount of wind energy providing electricity in the U.S., what would happen if the wind ever stops blowing? Nothing really - the lights will stay on, refrigerators will keep running and air conditions will keep working. As it so happens, wind energy has made the U.S. electrical supply more diversified and protects us against periodic shut downs from those pesky, sometimes-unreliable fossil fuel power plants and nuclear reactors.

Tweets from Fukushima worker: "It's so scary" - Normal air contains enough oxygen to ca... - 0 views

  • Breaking News: High level of radiation is making hydrogen from H2O, Fukushima Diary by Mochizuki, September 26, 2011:
  • These are the tonight’s tweets of actual Fukushima worker called Happy20790 I managed to come back safely today. We couldn’t work at reactor 1 today, again. Last week, they said they detected 4% of hydrogen but it turned out to be over 100%. The current measurement tool is to detected only flammable gas, but Tepco says probably it is all hydrogen. [...] We would have been all dead if we cut of the pipe [reportedly using blow torches]. Unbelievable story, but as our original schedule, we didn’t plan to check the presence of flammable gas. The process was added the day before the day. It’s so scary. [...] [T]hen we are going to inject nitrogen to cut out to pipes. but normal air contains 18% of oxygen, which is enough to cause a hydrogen explosion even without fire. It’s so scary. Injecting nitrogen may also cause lack of oxygen. [...] It’s probably that high radiation is producing hydrogen out of H2O. [...] From his valuable statements, we can tell the hydrogen is still being produced by the very high radiation hitting H2O in the reactor. Nobody has seen it by their own eyes, but the melted fuel rods must be very active still.

Radioactive Cesium from Shiitake Mushrooms Grown Indoors in Date City, Fukushima [16Jul11] - 0 views

  • (Update: 28 kg of Date City shiitake were sold within Fukushima. 129 kg of Motomiya City shiitake went to the fresh produce wholesale market in Tokyo, according to Asahi.)1,770 becquerels per kilogram. That's the first since the government started the sample testing of food items. Date City is more than 50 kilometers northwest of Fukushima I Nuclear Power Plant.From Yomiuri Shinbun (10:08AM JST 7/16/2011):
  • The Ministry of Health, Labor and Welfare announced on July 15 that 1,770 becquerels/kg of radioactive cesium was detected from shiitake mushrooms grown indoors in Date City, Fukushima Prefecture. The provisional safety limit is 500 becquerels/kg. Shiitake mushrooms grown in Motomiya City in Fukushima also tested 560 becquerels/kg of radioactive cesium. Already, 16 municipalities in Fukushima Prefecture restrict the shipment of shiitake mushrooms grown outdoors. This is the first time that shiitake mushrooms that were grown indoors tested above the safety limit. The national government will consider the shipment restriction.Where did this cesium come from, if the mushrooms were grown indoors? Is the indoor air just as contaminated as the outdoor air in Date City? Or was it the mushroom substrate blocks (for indoor cultivation) that were contaminated?
  • In the meantime, the minister in charge of the Fukushima nuke accident and the assistant of PM Kan apparently told the governor of Fukushima that the so-called "step 1" (stable cooling of the reactors, among others) of the so-called "roadmap" by TEPCO has been "successfully completed" (link is in Japanese).July 17 is the so-called "deadline" to so-called "complete" the so-called "step 1". Upon the so-called "completion", the government is set to announce the reduction and/or elimination of the "emergency evacuation-ready zone". Never mind that is where the radioactive cows that ate the radioactive rice hay come from.Date City was not even in the "emergency evacuation-ready zone" until June 30, even though the air radiation level had consistently measured high, the level of "planned evacuation zone".
