Latest radiation tests in Tokyo raise "unprecedented concerns" about Fukushima aftermat... - 1 views

  • Tokyo, Oct. 14 — Tokyo radiation measurements “raise major and unprecedented concerns about the aftermath of the Fukushima nuclear disaster.” -Robert Alvarez, a nuclear expert and a former special assistant to the United State Secretary of Energy “Radioactive substances are entering people’s bodies from the air, from the food. It’s everywhere. But the government doesn’t even try to inform the public how much radiation they’re exposed to.” -Kiyoshi Toda, a radiation expert at Nagasaki University’s faculty of environmental studies and a medical doctor“Everybody just wants to believe that this is Fukushima’s problem. But if the government is not serious about finding out, how can we trust them?” -Kota Kinoshita, one of the citizen groups’ leaders and a former television journalist

Rice Farmers in Japan Set Tougher Radiation Limits for Crops [14Oct11] - 0 views

  • Rice farmers near Japan’s crippled Fukushima nuclear plant will impose radiation safety limits that will only clear grains with levels so low as to be virtually undetectable after government-set standards were viewed as too lenient, curbing sales. Farmers now completing the harvest in areas affected by fallout from the nuclear station are struggling to find buyers amid doubts about cesium limits, which are less stringent than in livestock feed. No samples have been found exceeding the official limits. A self-imposed, near-zero limit on radiation in rice may help spur sales from Fukushima, which was the fourth-largest producer in Japan last year, representing about 5 percent of the total harvest. The prefectural office of Zen-Noh, Japan’s biggest farmers group, plans to only ship cesium-free rice to address safety concerns, as does the National Confederation of Farmers Movements, which includes about 30,000 producers nationwide.
  • “We advise our members to test their rice for radiation and sell only if results show no cesium is detected,” said Yoshitaka Mashima, vice chairman of the confederation. The government has tried to “hide inconvenient information, which is deepening consumer distrust.” The near-zero limit was set as very low levels of cesium are hard to detect. Testing equipment in Japan is unable to verify levels of cesium in food below 5 becquerels a kilogram, according to Mashima.
  • Fukushima Rice Japan set the maximum allowed level of cesium in food about a week after the March 11 earthquake and tsunami, based on recommendations from the International Commission on Radiological Protection. The health ministry set the rice ceiling at 500 becquerels a kilogram, while the agriculture ministry’s limit for feed is 300 becquerels. The agriculture ministry allowed rice planting in Fukushima and neighboring prefectures in April, excluding paddy fields containing more than 5,000 becquerels of cesium per kilogram.

  • Prefectural governments began approving farmers to ship their harvest if test results showed samples from their produce did not show cesium exceeding the limit. Still, rice millers are concerned about buying new crops from areas near the plant as the current cesium standard, applied to brown rice, doesn’t ensure the safety of its by- products, including bran.
  • Rice Bran Cesium levels in rice bran, an ingredient used in Japanese compound feed for livestock, is about seven times as high as brown rice, said Ryo Kimura, the chairman of Japan Rice Millers and Distributors Cooperative. Because of this, feed makers are reluctant to buy bran made from brown rice that may contain more than 40 becquerels a kilogram of cesium, he said. Brown rice is polished to produce milled rice for sale to retailers and by-products are shipped to makers of cooking oil, pickles and animal feed.
  • Demand for this year’s rice crop has also been weakened as consumers hoarded last year’s crop amid radiation concerns, Kimura said. Domestic food-rice inventories, excluding the government’s reserve, fell 16 percent to a three-year low of 1.82 million metric tons in June as consumers boosted purchases after the disaster. The volume is equal to 22 percent of Japanese rice demand in the year ended June 30.
  • Lower Prices “Consumers who see the current cesium standard as lenient won’t buy rice from polluted areas,” said Nobuyuki Chino, president of Continental Rice Corp. in Tokyo. “Wholesalers are seeking rice that tested negative for cesium as they know grain containing radioactivity, even if the amount is smaller than the official standard, won’t sell well.” Stockpiles may increase by more than 100,000 tons by next June because of a weak demand and a good harvest this year, dragging down prices, said Chino.
  • Low demand for rice harvested in eastern Japan, affected by radiation fallout from the Fukushima plant, is reflected in a price gap between Tokyo and Osaka grain exchanges, Chino said. Rice for November delivery on the Tokyo Grain Exchange settled at 14,400 yen ($184) a bag on Oct. 12, 4 percent cheaper than the price on the Kansai Commodities Exchange in the western city of Osaka. The Kansai exchange trades rice produced in western Japan, while the Tokyo bourse handles rice grown in the east, including Fukushima prefecture.
  • Stricter Control The government has been slow to take measures to ease safety concerns as tighter regulation will boost costs for radiation testing, adding troubles to the nation struggling with swelling fiscal deficits, said Naoki Kazama, an upper-house lawmaker from the ruling Democratic Party of Japan. Stricter control may also increase a ban on shipments of local farm products and cause shortages, sending producers out of business and boosting compensation payments by Tokyo Electric Power Co., operator of the Fukushima nuclear plant.
  • “The government should put a priority on protecting human health, especially of our children,” Kazama said in an interview in Tokyo. “Now they are paying consideration to the interests of various parties evenly.” Kazama has proposed that all foods be tested for radioactive contamination and their radiation levels be labeled. The health ministry, which rejected the proposal as unfeasible, plans to revise cesium standards in food in line with recommendations from the Food Safety Commission.
  • Health Effects An expert panel on the commission compiled a report in July that said more than 100 millisieverts of cumulative effective doses of radiation over a lifetime could increase the risk of health effects in humans. The amount doesn’t include radiation from nature and medical exposure, it said.

Fukushima victims: homeless,desperate and angry[18Oct11] - 0 views

  • They are furious at the red tape they have to wade through just to receive basic help and in despair they still cannot get on with their lives seven months after the huge quake and tsunami triggered the world's worst nuclear disaster in 25 years.Shouts fill a room at a temporary housing complex where seven officials, kneeling in their dark suits, face 70 or so tenants who were forced to abandon their homes near the Fukushima nuclear plant after some of its reactors went into meltdown after the March 11 quake struck.
  • e don't know who we can trust!" one man yelled in the cramped room where the officials were trying to explain the hugely complex procedures to claim compensation."Can we actually go back home? And if not, can you guarantee our livelihoods?"About 80,000 people were forced to leave their homes by the nuclear crisis.While the owner of the plant, Tokyo Electric Power Co, has made temporary payments to some victims, it was only last month that it finally began accepting applications for compensation.
  • But the procedure is so complicated that it seems to just make things worse.After claimants have read a 160-page instruction manual, they then have to fill in a 60-page form and attach receipts for lodging, transportation and medical costs."It's too difficult. I'm going to see how it goes. I don't want to rush and mess up," said Toshiyuki Owada, 65, an evacuee from Namie town, about 20 km (12 miles) away from the plant.Owada is one of many who still has not applied for compensation even though they have lost jobs or businesses and are running out of cash.COMPLEX AND UNFAIRThe complexity of the task is one deterrent.

  • There is another -- the perception that Tepco is not playing fair.Confidence in the authorities is low. The government is seen as having bungled its early response to the crisis and being secretive about what was really happening.Tepco is accused of failing to take sufficient safety measures at the Fukushima plant even though it knew the risks and then deliberately underplaying the extent of the accident.
  • It is also seen as insensitive.One clause in the original instruction booklet telling victims they would have to agree to waive their right to challenge the compensation amount in order to receive payment provoked a public uproar
  • Chastised by the government, the company promised to drop the clause, issued a simplified 4-page instruction booklet and assigned 1,000 employees to Fukushima prefecture to help victims with the process."There may be times when the content is difficult to understand or in some cases our employee in charge may not grasp it fully, but we would like to explain and respond as carefully as possible," said Tepco spokesman Naoyuki Matsumoto.A government panel overseeing the compensation scheme estimates claims are likely to reach 3.6 trillion yen ($46.5 billion) in the financial year to next March.FEW CLAIMANTSBut so far just 7,100 individuals have applied to Tepco for compensation out of the 80,000 it send forms to.
  • And of the 10,000 businesses in the Fukushima area, a mere 300 have submitted claims.The company expects a total of 300,000 claims from businesses given that the impact of the radiation crisis has been so widespread.Victims can sue but that is rare.Junichi Matsumoto, a Tepco official, said the utility faces about 10 lawsuits so far. He declined to disclose details but said some were seeking more than the firm deemed appropriate.
  • uichi Kaido, an attorney and the secretary-general of the Japan Federation of Bar Associations, said lawsuits are considered a last resort in conservative rural northeast Japan."In the end, many lawsuits could take place," he said.
  • But the majority is thinking of first speaking with Tokyo Electric or seeking mediation."

Kashiwa City's Radioactive Dirt: 276,000 Bq/Kg of Cesium [22Oct11] - 0 views

  • The highly radioactive dirt in Kashiwa City in Chiba, which measured 57.5 microsieverts/hr 30 centimeters below the surface, was not from radium after all or any other nuclides that are used in industrial or medical use (some suggested cobalt-60, for example). It was from radioactive cesium.On October 22 Kashiwa City announced the result of the analysis of three dirt samples from the location at different depth (one on the surface, two at 30 centimeter deep). The analysis was done on October 22. The unit is becquerels per kilogram:Sample A (surface dirt)Radioactive iodine: NDCesium-134: 70,200Cesium-137: 85,100Total cesium: 155,300
  • Sample B1 (30 centimeters below the surface)Radioactive iodine: NDCesium-134: 87,000Cesium-137: 105,000Total cesium: 192,000Sample B2 (30 centimeters below the surface)Radioactive iodine: NDCesium-134: 124,000Cesium-137: 152,000Total cesium: 276,000The address of the location is announced by the city as: 柏市根戸字高野台457番3地先. According to the residents, the place is a strip of open space between the residential area and the industrial area, and is used as playground by many residents, young and old.
  • On receiving the result of the analysis, the Ministry of Education and Science, who had expressed doubt that this high radiation spot in Kashiwa had anything to do with the Fukushima I Nuclear Power Plant accident, now says it cannot deny that it is the result of the accident. The ratio of cesium-134 and cesium-137 is consistent with the radio from the accident.Some speculate that someone in the city cleaned out his house and dumped the resulting radioactive sludge and dirt in this location.What I find it odd is the mismatch of the radiation on the dirt surface, 57.5 microsieverts/hour, and the density of radioactive cesium, maximum 276,000 becquerels/kilogram. The density is too low to account for the extremely high radiation. Cesium alone may not account for the high radiation, but There's no mention in the city's announcement whether it is going to test for other gamma nuclides not to mention alpha and beta.

We may be too late to evacuate [15Oct11] - 0 views

  • In Chernobyl, 0.09 uSv/h → Children started having symptoms. (near radiation level as westen Tokyo) 0.16 uSv/h → Adults got leukemia within 5 years. (near radiation level as Adachiku) 0.232 uSv/h → Mandatory evacuation area in Cheronobyl. (near radiation level as Asakusa or Tokyo Disneyland) I received a lot of queries. I would like to add some more explanation to this. This is a lecture of Ms. Noro Mika, who runs the NPO “Bridge to Chernobyl”
  • Annotator’s comment: Because I believe that breast-feeding has a tremendous influence not only on nutrition, but also on the mental aspect; that’s why I hope that the mothers who are breast-feeding their children pay strict attention also to the their level of internal exposure and evacuate as soon as possible. Because the danger of the radioactive substances is known well enough, the world is watching the way Japan is dealing with the situation. A country which abandons its children and doesn’t value their lives is not a country worthy of trust.
  • In Chernobyl, an area 30 km from the nuclear plant, where the radiation level was 0.232 μSv/hour, was declared “no-entry zone”. In Chernobyl, in area where radiation levels were daily even 0.16 μSv/hour have been admitted as being dangerous, and in fact, adults got leukemia and died. Annotator: In case, in Kamakura, were I live, the level is 0.16 μSv/hour. Concerning the gamma dose rate in a certain spots one meter above the ground level, the radiation levels declared officially for Kamakura city are generally between 0.11〜0.14 μSv/hour. Radioactivity, in case of of iron, concrete, etc causes the oxidation and corrosion, but in humans accelerates the aging process and cause them sickness.

  • And the effects start appearing in 2~3 years. We didn’t understand from the beginning where the hot spots were. But after checking later the areas where a lot of children got sick, in Belarus probably the radioactive substances were easily carried by the wind because the flat level ground, but it became clear that in areas 20~30 km from the plant there were places contaminated about just as much as Chernobyl. Kamakura is about 300 kilos away from Fukushima in a straight line. Based on the results of the investigations made after the nuclear accident in Chernobyl, in Europe the fact of assuming that 800km from the nuclear plant might be contaminated has been made taken into consideration as a basic rule for safety.
  • In Chernobyl, because contaminated farm products were made served in school lunches, about 70% of the children suffered from various kinds of health damages. Those (health problems) were not limited to their generation, and when those children became parents their problems passed to their children too. Because radioactive substances have similarities with nutrients like calcium, the mammals will feed a lot of them to their babies. Radioactive substances get easily out of their bodies by milk – hence, there were many cases when after giving birth to their first baby, a large quantity of radioactive substances were passed to the (first born) child and the mother’s health improved, but those children had serious congenital disorders (became people with serious disabilities).
  • She has been visiting Chernobyl for 25 years and help children to accept in Hokkaido for one month etc.. Currently, the radiation levels in some parts of Kanto area are 3 mSv/year. Annotator’s comment: According to the Ministry of Education, Culture, Sports, Science and Technology, the numerical values announced by the local government prove only the emission of gamma rays. The iodine and the cesium decay while emitting beta rays. If we have to deal strictly with gamma rays emissions, the degree of contamination can be understood, but we can’t measure the level of individual external exposure. Besides, the numerical values detected at the monitoring posts are measured at 10m above the ground level or even more.
  • Besides, there is no country who would buy things from a country that loosens it’s standards. The gov and Tepco spread misinformation (misinform the population). They should think about requesting the farmers give up growing farming products which are contaminated, give them compensation, and provide them new and safe farmlands.
  • n case of Chernobyl, party members, doctors and a nurses, teachers could afford to evacuate, because they could keep sustaining themselves even if they moved, but the poor people could not afford to evacuate. The symptoms which appeared at children who remained were the following: Headache nosebleed diarrhea thyroid problems not growing taller hard to recover after catching a cold swelling of the lymphatic glands, easily get sick with pneumonia kidney pain renal cancer
  • [that I have a] (because while radioactivity leaves the body, the urinary tract is affected) pain in the back side of the knee arthralgia wounds that take a long time to cure asthma hair loss problems with their hair growing alteration in visual acuity poor appetite poor concentration fatigability/easily getting tired cardiac pain (cardialgia) low resistance to diseases. The school lessons were shortened to 25 minutes, and because their kidneys became week, there are primary school children who wet their beds.
  • Even after becoming adults, the following cases were recorded: increase of myocardial infarcts an increase in the nr of sudden deaths death of young people in their 30th Accumulation of cesium in heart – even if eliminate from their bodies it (cesium) enters the body again after eating being exempted from the military service for having small holes in their hearts Regarding their children, the following medical cases were recorded - Brain damage, proved by the fact that they were slow in eating their meals.
  • Mothers of many children who were different from the other normal children give them to adoption, even if they didn’t have renal surgery or health problems, or a handicap. This kind of things are happening. (Source) German Translation

#Fukushima I Nuke Plant: Mountains of Tyvek Suits at J-Village[17Oct11] - 0 views

  • Discarded Tyvek suits, 480,000 of them, which TEPCO would have to treat as low-level radioactive waste and dispose accordingly (unlike regular garbage or sewer sludge ash in Tokyo, which may be more contaminated than the Tyvek suits in Fuku I):
  • New Tyvek suits being distributed. Inventory at J-village, about 500,000:
  • A Tyvek suit costs about 1,000 yen (US$13) average in Japan, so it is costing TEPCO 1 billion yen ($13 million). As is usual for a big corporation like TEPCO, cost-cutting always starts at the bottom; the company is asking the Fuku I workers not to take more than one Tyvek suit.According to one of the workers who tweet from Fukushima I Nuke Plant, TEPCO has already downgraded Tyvek suits quality. It used to be 1,440 yen per piece, now it's 840 yen, achieving 40% cost reduction.The government, whether national or prefectural, shows no sign of helping TEPCO in any way when it comes to supporting and taking care of the workers at Fuku I. Instead, they want to waste taxpayers' money on inviting foreigners on free Japan trips (1 billion yen), inviting big social media writers (1.5 billion yen) to Tohoku, inviting IAEA "decontamination" mission who just recommended relaxing the standards (1 billion yen). Fukushima Prefecture is really raking in, over 100 billion yen for building a new cancer hospital at the medical university presided by Dr. Shunichi Yamashita.

Citizens' forum queries nuclear 'experts' [23Oct11] - 0 views

  • To whom does scientific debate belong? That was a central question raised by many of the 200-plus people who attended a citizens' forum in Tokyo on Oct. 12, as they criticized the ways in which the Japanese government and radiation specialists working for it are assessing and monitoring the health effects of the ongoing nuclear disaster at the Fukushima No. 1 nuclear power plant. The daylong conference, organized by the Japanese citizens' groups SAY-Peace Project and Citizens' Radioactivity Measuring Station (CRMS), featured experts who dispute much of the evidence on which the government has based its health and welfare decisions affecting residents of Fukushima Prefecture and beyond. Organizers of the event were also demanding that the government take into consideration the views of non-experts — and also experts with differing views from those of official bodies such as the International Commission on Radiological Protection (ICRP). The Japanese government has constantly referred to the ICRP's recommendations in setting radiation exposure limits for Fukushima residents.
  • One of the driving forces for the citizens' forum was a desire to challenge the conduct and much of the content of a conference held Sept. 11-12 in Fukushima, titled the "International Expert Symposium in Fukushima — Radiation and Health Risk." That conference, sponsored by the Nippon Foundation, involved some 30 scientists from major institutions, including the ICRP, the World Health Organization, the International Atomic Energy Agency and the United Nations Scientific Committee on the Effects of Atomic Radiation. Although the proceedings were broadcast live on U-stream, the event itself was — unlike the Tokyo forum — closed to the public. Some citizens and citizens' groups claimed that this exclusion of many interested and involved parties — and the event's avowed aim of disseminating to the public "authoritative" information on the health effects of radiation exposure — ran counter to the pursuit of facilitating open and free exchanges among and between experts and citizens on the many contentious issues facing the nation and its people at this critical time.
  • In particular, there was widespread criticism after the Fukushima conference — which was organized by Shunichi Yamashita, the vice president of Fukushima Medical University and a "radiological health safety risk management advisor" for Fukushima prefectural government — that its participants assumed from the outset that radioactive contamination from the plant's wrecked nuclear reactors is minimal. Critics also claimed that the experts invited to the conference had turned a collective blind eye to research findings compiled by independent scientists in Europe in the aftermath of the 1986 Chernobyl nuclear disaster in present-day Ukraine — specifically to findings that point to various damaging health consequences of long-term exposure to low-level radiation. So it was that those two citizens' groups, angered by these and other official responses to the calamity, organized the Oct. 12 conference held at the National Olympics Memorial Youth Center in Shibuya Ward. Among the non-experts and experts invited to attend and exchange their views were people from a wide range of disciplines, including sociology, constitutional law and pediatrics. On the day, some of the speakers took issue with the stance of the majority of official bodies that the health damage from Chernobyl was observed only in a rise in the number of cases of thyroid cancers.
  • ...5 more annotations...
  • Eisuke Matsui, a lung cancer specialist who is a former associate professor at Gifu University's School of Medicine, argued in his papers submitted to the conference that the victims of Chernobyl in the neighboring present-day country of Belarus have suffered from a raft of other problems, including congenital malformations, type-1 diabetes and cataracts. Matsui cited a lengthy and detailed report of research by the Russian scientists Alexey V. Yablokov, Vassily B. Nesterenko and Alexey V. Nesterenko that was published in 2007, and republished in English in 2009 by the New York Academy of Sciences under the title "Chernobyl: Consequences of the Catastrophe for People and the Environment." Matsui stressed that, based on such evidence, the Japanese government should approve group evacuations of children — at the expense of the plant's operator, Tokyo Electric Power Co. — from certain parts of Fukushima Prefecture. He cited some areas of the city of Koriyama, 50 to 60 km from the stricken nuclear plant, where soil contamination by radioactive cesium-137 has reached 5.13 Curies per sq. km. That is the same as in areas of Ukraine where residents were given rights to evacuate, Matsui said. In fact in June, the parents of 14 schoolchildren in Koriyama filed a request for a temporary injunction with the Fukushima District Court, asking it to order the city to send their children to schools in safer areas.
  • In the ongoing civil suit, those parents claim that the children's external radiation exposure has already exceeded 1 millisievert according to official data — the upper yearly limit from all sources recommended by the ICRP for members of the public under normal conditions. Following a nuclear incident, however, the ICRP recommends local authorities to set the yearly radiation exposure limit for residents in contaminated areas at between 1 and 20 millisieverts, with the long-term goal of reducing the limit to 1 millisievert per year. Meanwhile, Hisako Sakiyama, former head researcher at the National Institute of Radiological Sciences, delved into the non-cancer risks of exposure to radiation. In her presentation, she referred to a report compiled in April by the German Affiliate of International Physicians for the Prevention of Nuclear War (IPPNW). Titled "Health Effects of Chernobyl: 25 years after the reactor catastrophe," this documents an alarmingly high incidence of genetic and teratogenic (fetal malformation) damage observed in many European countries since Chernobyl.
  • Sakiyama also pointed out that the German report showed that the incidence of thyroid cancer due to radiation exposure was not limited to children. For instance, she cited IPPNW survey findings from the Gomel district in Belarus, a highly-contaminated area, when researchers compared the incidence of thyroid cancer in the 13 years before the Chernobyl explosion and the 13 years after. These findings show that the figures for the latter period were 58 times higher for residents aged 0-18, 5.3 times higher for those aged 19-34, 6 times higher for those aged 35-49, and 5 times higher for those aged 50-64. "In Japan, the government has a policy of not giving out emergency iodine pills to those aged 45 and older (because it considers that the risk of them getting cancer is very low),"' Sakiyama said. "But the (IPPNW) data show that, while less sensitive compared to children, adults' risks go up in correspondence with their exposure to radioactivity."
  • Further post-Chernobyl data was presented to the conference by Sebastian Pflugbeil, a physicist who is president of the German Society for Radiation Protection. Reporting the results of his independent research into child cancers following the Chernobyl disaster, he said that "in West Germany ... with an exposure of 1 millisievert per year, hundreds of thousands of children were affected." He noted, though, that any official admissions regarding health damage caused by the 1986 disaster in the then Soviet Union came very slowly and insufficiently in Europe. Indeed, he said the authorities denied there were health risks for years afterward. In response, an audience member who said he was a science teacher at a junior high school in Kawaguchi, Saitama Prefecture, asked Pflugbeil to exactly identify the level of exposure beyond which residents should be evacuated. While acknowledging that was a very difficult question, the German specialist noted later, however, that he would think pregnant women should probably leave Fukushima — adding, "I have seen many cases over the years, but I come from Germany and it's not easy to judge (about the situation in Japan)."
  • At a round table discussion later in the day, as well as discussing specific issues many participants made the point that science belongs to the people, not just experts — the very point that underpinned the entire event. As Wataru Iwata, director of the Fukushima-based citizens' group CRMS, one of the forum's organizers (which also conducts independent testing of food from in and around Fukushima Prefecture) put it: "Science is a methodology and not an end itself." In the end, though the citizens' forum — which ran from 9:30 a.m. to 10 p.m. — arrived at no clear-cut conclusions, organizers said that that in itself was a good outcome. And another conference involving citizens and scientists is now being planned for March 2012.

Worst Nuclear Disasters - Civilian [15Apr11] - 0 views

  • The top civilian nuclear disasters, ranked by International Nuclear and Radiological Event Scale. Worst Civilian Nuclear Disasters 1. Chernobyl, Soviet Union (now Ukraine) April 26, 1986 INES Rating: 7 (major impact on people and environment)
  • The worst nuclear disaster of all time resulted from a test of the reactor’s systems. A power surge while the safety systems were shut down resulted in the dreaded nuclear meltdown. Fuel elements ruptured and a violent explosion rocked the facility. Fuel rods meted and the graphite covering the reactor burned. Authorities reported that 56 have died as a direct result of the disaster—47 plant workers and nine children who died of thyroid disease. However, given the Soviet Union’s tendency to cover up unfavorable information, that number likely is low.  International Atomic Energy Agency reports estimate that the death toll may ultimately be as high as 4,000. The World Health Organization claims that it’s as high as 9,000. In addition to the deaths, 200,000 people had to be permanently relocated after the disaster. The area remains unsuitable for human habitation. 2. Fukushima, Japan March 11, 2011 INES Rating: 7 (major impact on people and environment) Following a 9.0 magnitude earthquake and tsunami, Japan’s Fukushima nuclear power facility suffered a series of ongoing equipment failures accompanied by the release of nuclear material into the air. The death toll for this currently is at two but is expected to rise and as of April 2011, the crisis still ongoing. A 12 mile evacuation area has been established around the plant.
  • 3. Kyshtym, Soviet Union Sept. 29, 1957 INES Rating: 6 (serious impact on people and environment) Poor construction is blamed for the September 1957 failure of this nuclear plant. Although there was no meltdown or nuclear explosion, a radioactive cloud escaped from the plant and spread for hundreds of miles. Soviet reports say that 10,000 people were evacuated, and 200 deaths were cause by cancer.

  • 4. Winscale Fire, Great Britain Oct. 10, 1957 INES Rating: 5 (accident with wider consequences) The uranium core of Britain’s first nuclear facility had been on fire for two days before maintenance workers noticed the rising temperatures. By that time, a radioactive cloud had already spread across the UK and Europe. Plant operators delayed further efforts in fighting the fire, fearing that pouring water on it would cause an explosion. Instead, they tried cooling fan and carbon dioxide. Finally, they applied water and on Oct. 12, the fire was out. British officials, worried about the political ramifications of this incident, suppressed information. One report, however, says that in the long run, as many as 240 may have died from accident related cancers. 5.
  • Three Mile Island, Pennsylvania, US March 28, 1979 INES Rating: 5 (accident with wider consequences) Failure of a pressure valve resulted in an overheating of the plant’s core and the release of 13 million curies of radioactive gases. A full meltdown was avoided when the plant’s designers and operators were able to stabilize the situation before contaminated water reached the fuel rods. A full investigation by the US Nuclear Regulatory Commission suggests that there were no deaths or injuries resulting from the incident.
  • 6. Golania, Brazil Sept, 1987 INES Rating: 5 (accident with wider consequences) Scavengers at an abandoned radiotherapy institute found a billiard ball sized capsule of radioactive cesium chloride, opened it and then sold it to a junkyard dealer. The deadly material was not identified for more than two year, during which time it had been handled by hundreds, including some who used the glittery blue material for face paint. Of the 130,000 tested, 250 were discovered to be contaminated and 20 required treatment for radiation sickness. Four died, including the two who originally found the capsule, the wife of the junkyard owner and a small girl who used the powder as face paint. 7. Lucens, Switzerland January 1, 1969 INES Rating: 5 (accident with wider consequences) When the coolant on a test reactor facility in a cave in Switzerland failed during startup, the system suffered a partial core meltdown and contaminated the cavern with radioactivity. The facility was sealed and later decontaminated. No known deaths or injuries.
  • 8. Chalk River, Canada INES Rating: 5 (accident with wider consequences) May 24, 1958 Inadequate cooling lead to a fuel rod fire, contaminating the plant and surrounding labs. 9. Tokaimura,Japan Sept. 30, 1999 INES Rating: 4 (accident with local consequences) The nuclear plant near Tokai had not been used for three years when a group of unqualified workers attempted to put more highly enriched uranium in a precipitation tank than was permitted. A critical reaction occurred and two of the workers eventually died of radiation exposure. Fifty six plant workers and 21 others also received high doses of radiation. Residents within a thousand feet of the plant were evacuated.
  • 10. National Reactor Testing Station, Idaho Falls, Idaho January 3, 1961 INES Rating: 4 (accident with local consequences) Improper withdrawal of a control rod led to a steam explosion and partial meltdown at this Army facility. Three operators were killed in what is the only known US nuclear facility accident with casualties.

Ocean Absorbed 79 Percent Of Fukushima Fallout [29Oct11] - 0 views

  • About 19 percent of airborne fallout from the Fukushima nuclear disaster was deposited in Japan, and only about 2 percent made it to other land areas in Asia and North America, according to a study published this week by the European Geosciences Union. The bulk was absorbed by the Pacific Ocean.
  • Opponents of nuclear energy have seized on the European study because it describes the total release at Fukushima as “massive.” It finds that twice as much cesium 137 was released at Fukushima than originally reported. And it says “high concentrations” reached North America and Europe. It examines two radionuclides in particular–xenon 133 and cesium 137–and measures the total release in terabecquerels.
  • Altogether, we estimate that 6.4 TBq of 137Cs, or 19 percent of the total fallout until 20 April, were deposited over Japanese land areas, while most of the rest fell over the North Pacific Ocean,” the authors write. “Only 0.7 TBq, or 2 percent of the total fallout were deposited on land areas other than Japan.” Scientists generally regard ocean absorption of fallout preferable to land deposits, because water absorbs radiation and the volume of the ocean dilutes it. On land, radioactive isotopes can be consumed by livestock and concentrated in milk and other food sources. The study also notes that airborne emissions of cesium 137 continued until March 19, when Japanese authorities began spraying water on the spent fuel pool of reactor #4. “This indicates that emissions were not only coming from the damaged reactor cores, but also from the spent-fuel pool of unit 4 and confirms that the spraying was an effective countermeasure.”

The Japanese Government's Appalling Earthquake, Nuclear Response (1) - The Daily Beast ... - 0 views

  • Residents in the radiation danger zone, instructed to stay inside their homes, are venturing out in search of food and fuel. A Japanese businessman in the country's northeast tells Joan Juliet Buck how government incompetence is killing people who escaped the earthquake.
  • Writer, cultural critic, and actor Joan Juliet Buck wrote to a foreign-born Japanese friend in the food business to ask him how we in America could help Japan. Below is his answer. Tellingly, he does not want to be identified
  • “As you are a journalist,” he wrote back, “first I would like to explain how the Japanese government and bureaucrats are incompetent against the crisis.”

  • In the email he sent me, he combined local press reports with his own observations. The Japanese Red Cross can’t accept the food he is trying to donate for the refugees because there is no gasoline to get it into the stricken areas. Vehicles cannot get through to the affected areas, and Japan’s military, called the Self Defense Force, was forced to travel to the Tohoku region, in the country’s northeast, in a civilian ferry. People ordered to stay in their homes to shelter from radioactive emissions have neither food nor heat and venture out on foot into maximum danger to look for food.
  • Here’s a personal look at the situation in Japan today.“This is all the information we’re getting from the Japanese press: I’m giving it to you in bullet points.
  • 1. There is no fuel for heating.
  • No FuelBecause the government did not ease the regulation on the stocks of fossil fuels, there is a severe lack of fuel in all of Tokyo and the Tohoku area.
  • 2. Food and medicine are not arriving at the refugee centers.
  • 5. Due to the lack of fuel, elderly people are dying of cold, stress, malnutrition, and lack of medicine. Twenty-four of them have died so far.
  • 7. Medical doctors cannot go into the region because there is nowhere to get gasoline.
  • Slow Decision MakingThe U.S. government immediately sent an aircraft carrier, the USS Ronald Reagan, after the earthquake. It arrived in the Tohoku area on March 13 at 4 a.m. Japanese time. Last night, on March 16, I learned that the Japanese Self Defense Force from Hokkaido had just left for the Tohoku area. The force was traveling to Tohoku on a civilian ferry and had planned to arrive today, March 17.Just today the government decided to send fuel to the region in need.
  • People Around the Nuclear FacilitiesWithin a 30-kilometer radius around the plants, the government has instructed the refugees to stay sealed indoors. However, the government is not sending in food and fuel to these households and these refugee centers. As food and/or fuel run out, the refugees are walking away from their houses and being exposed to radiation.
  • Public Sentiment Is Inhibiting PressureCurrently no press is in the mood to criticize the government. The general public believes that criticism should come later. The opposition parties are also quiet. There is no pressure on the bureaucrats and government to improve the situation.

Japan radiation expert: Plutonium-238 from inside reactors went far from Fukushima afte... - 0 views

  • Mainichi has a report featuring radiochemical expert Michiaki Furukawa, professor emeritus at Nagoya University:
  • He says that some reports about plutonium have been misleading. “When the disaster first happened, there were media reports saying ‘plutonium won’t make it far because it’s a large and heavy element,’ but no one who’s done serious research in environmental radioactivity would say such a thing.” “At the very least, plutonium-238 had to have come from the explosions (at the plant). The plutonium that had heated up inside the reactors turned into fine particles when it came in contact with water, and was dispersed with the water vapor released in the explosions. Yet, Furukawa says, “Since the plutonium takes the form of particles — unlike the gaseous radioactive iodine — it probably didn’t fly 100 kilometers.”
  • Some previous reports, however, appear to refute Furakawa’s claim: Takashi: Plutonium evaporated and spread around as gas after Fukushima meltdowns "Very high concentrations" of hot particles in Pacific NW during April, May -- Includes plutonium and americium (AUDIO) Nuclear expert says Americium has been found in New England -- Element even heavier than Uranium (VIDEO) Neutron ray measured in Tokyo -- Uranium-235 found in Chiba -- Can't be detected by most geiger counters (PHOTO & VIDEO) Uranium-234 detected in Hawaii, Southern California, and Seattle Also in the Mainichi article, Hiroshi Ishihara, who heads the Medical Treatment for the High Dose Exposure Research Group at the National Institute of Radiological Sciences (NIRS) in Chiba, speaks about plutonium:]

  • He says that “inhaling 910 becquerels or more of plutonium-238 is believed to slightly raise the possibility of cancer.” He adds that this will equal a cumulative radiation exposure of 100 millisieverts in 50 years… just from the plutonium-238. “Even if one were to have inhaled plutonium soon after the explosions took place, it’s hard to think that the amount was enough to have any effects health-wise.” Even the Nuclear Safety Commission of Japan disagrees, saying “We do not take the position that plutonium is safe in amounts up to 910 becquerels.” Read More: Unknowns about radioactive materials warrant vigilance amid delayed gov’t action

Intelligent absorbent removes radioactive material from water 01Nov11[ - 0 views

  • Nuclear power plants are located close to sources of water, which is used as a coolant to handle the waste heat discharged by the plants. This means that water contaminated with radioactive material is often one of the problems to arise after a nuclear disaster. Researchers at Australia's Queensland University of Technology (QUT) have now developed what they say is a world-first intelligent absorbent that is capable of removing radioactive material from large amounts of contaminated water, resulting in clean water and concentrated waste that can be stored more efficiently. The new absorbent, which was developed by a QUT research team led by Professor Huai-Yong Zhu working in collaboration with the Australian Nuclear Science and Technology Organisation (ANSTO) and Pennsylvania State University, uses titanate nanofiber and nanotube technology. Unlike current clean-up methods, such as a layered clays and zeolites, the new material is able to efficiently lock in deadly radioactive material from contaminated water and the used absorbents can then be safely disposed of without the risk of leakage - even if the material were to become wet.
  • When the contaminated water is run through the fine nanotubes and fibers, the radioactive Cesium (Cs+) ions are trapped through a structural change. Additionally, by adding silver oxide nanocrystals to the outer surface, the nanostructures are able to capture and immobilize radioactive iodine (I-) ions used in treatments for thyroid cancer, in probes and markers for medical diagnosis, and also found in leaks of nuclear accidents. "One gram of the nanofibres can effectively purify at least one ton of polluted water," Professor Zhu said. "This saves large amounts of dangerous water needing to be stored somewhere and also prevents the risk of contaminated products leaking into the soil." "Australia is one of the largest producers of titania that are the raw materials used for fabricating the absorbents of titanate nanofibres and nanotubes. Now with the knowledge to produce the adsorbents, we have the technology to do the cleaning up for the world," added Professor Zhu.
