  • Fish taken from a lake in northern Vermont had similar levels of strontium-90 and cesium-137 as fish taken from the Connecticut River near Vermont Yankee nuclear power plant in Vernon. During a Feb. 3 meeting of the House Fish, Wildlife and Water Resources Committee in the Vermont Statehouse, committee members heard from Bill Irwin, chief of radiological health for the Vermont Department of Health. "We got preliminary results from our fish sample analysis from Lake Carmi in northern Franklin County," Irwin told the Reformer on Monday. Irwin said Lake Carmine, in Enosburg Falls, is about as far away from Yankee as you can get and still be in the Green Mountain State. "The results are that cesium-137 and strontium-90 in Lake Carmi fish is in the same range as Connecticut River fish," said Irwin. "We take this as some evidence that all fish in Vermont are likely to have radioactive cesium and strontium at these levels and that, as we've hypothesized, it is from nuclear weapons fallout and the releases of Chernobyl. All of us are glad to have proof and not just conjecture." The fish taken from Lake Carmi were small-mouth bass, he said, and were taken from the lake by Vermont Fish and Wildlife fisheries personnel. Cesium was found in both edible and inedible portions of the bass, he said, while strontium was found only in inedible portions, which include bones, the head, fins and scales. "There's no danger in eating the fish," said Irwin. "Should we ever find that there are reasons to restrict diet from any sampling for any kind of radioactive or toxicological events, we would keep in mind different cultures have different diets."
  • In the same analyses, the fish had almost 500 times more potassium-40 in them than they do cesium-137, he said. Potassium-40 is a naturally occurring radioactive material that is in nearly everything and was created when the planet was formed billions of years ago, said Irwin. A fish taken from the Connecticut River in 2010 had the highest levels of strontium-90 in bone that his department has seen in any samples. "In that same sample we did find very low but measurable amounts of strontium-90 in the meat of the fish," said Irwin, which could have been a sampling or contamination error. "But we don't know that." The sampling is part of an ongoing multi-state operation to help determine what is the level of the two radioactive isotopes in fish in Vermont, New Hampshire, Massachusetts and New York. "We hope to further populate this data with fish taken from waters unaffected by nuclear power plants," said Irwin. The states are also working with the a Food and Drug Administration laboratory in Winchester, Mass., to develop sampling and analysis protocols. When more data has been assembled from around the region, Irwin said they hope to publish it in scientific journals. The results of the sampling from Lake Carmi will be posted soon on DOH's website, he said. When this year's fishing season begins, Fish and Wildlife personnel will be taking more fish for the Department of Health.

#Radiation in Japan: 60,000 Bq/kg Cesium in Riverbed Soil in Fukushima [16Nov11] - 0 views

  • On November 15, the Ministry of the Environment announced the result of the survey of the radioactive material density in bottom soil in 193 locations in rivers, lakes and dams in Fukushima Prefecture. Radioactive cesium was detected in almost all locations, with the highest density of 60,000 becquerels/kg of radioactive cesium in the riverbed soil in the Ota River that runs through Minami Soma City, which was designated as "evacuation-ready zone" after the Fukushima I Nuclear Power Plant accident.
  • The Ministry also conducted the survey of the water. Maximum 27 becquerels/liter of radioactive cesium was detected in the water from a dam inside the "no-entry zone" [within 20-kilometer radius], but in most locations it was not detected. The Ministry's analysis is that "radioactive materials have been absorbed by sludge and sands and sunk to the bottom, and that is why the radiation density is high [in the soil in rivers, lakes and dams]."The survey result is not yet uploaded at the Ministry's website.The provisional "safety" standard for drinking water in Japan is 200 becquerels/liter of radioactive cesium. (For reference, in Belarus, it is 10 becquerels/kg.)

NUCLEAR POWER - Resisting "Rust Belt" reactors' radioactive risks! [04Aug12] - 0 views

  • As if the closing steel mills and automobile manufacturing plants weren't bad enough, some of the oldest, most risky atomic reactors in the U.S. are located in the Midwest. Worse still, they are on the shores of the Great Lakes, putting at risk the drinking water supply for 40 million people downstream in the U.S., Canada, and a large number of Native American First Nations. Altogether, 33 atomic reactors are located on the shorelines of the Great Lakes. Two of the most infamous of these radiologically risky "Rust Belt reactors" are Entergy Nuclear's Palisades in southwest Michigan, and FirstEnergy's Davis-Besse in northwest Ohio.
  • Last month, U.S. Rep. Ed Markey (D-MA), a long-time watchdog on the nuclear industry, wrote the U.S. Nuclear Regulatory Commission (NRC) about an acidic, radioactive leak representing a "crisis in the control room at the Palisades nuclear power plant." The leakage had been ongoing for a year, and was being "contained" in glorified buckets referred to by Entergy PR spokesman Mark Savage as "catch basins." Although the leak came to light when Palisades was forced to shutdown after its rate reached more than 30 gallons per day, it had been ongoing for months at a rate of 15 gallons per day. The tritiated and borated water is leaking from a 300,000 gallon Safety Injection Refueling Water storage tank, which is safety critical for both reactor core and radiological containment cooling. Whistleblowers contacted Washington, D.C. attorney Billie Pirner Garde, who alerted Rep. Markey, who wrote NRC. The NRC Office of Investigations has launched a probe into potential Entergy wrongdoing. On July 17th, NRC issued a "Confirmatory Action Letter" which enables Palisades to keep operating into 2013, even if the leak increases to nearly 38 gallons per day!
  • Markey demanded a copy of an internal Entergy report surveying its own workers on "safety culture" at Palisades. Michigan Radio obtained a copy, which reveals "a lack of accountability at all levels," and a workforce deeply distrustful of management, fearful that they will be harassed and punished if they dare to raise safety concerns.

EnergySoultions Contracts with Studsvik for Nuclear Waste Processing [10Feb11] - 0 views

  • EnergySolutions Inc. is making a deal with a Sweden-based competitor, Studsvik, to dispose of solid nuclear waste in Utah. The Deseret News of Salt Lake City reported Tuesday that EnergySolutions signed a contract in December with Studsvik Inc. That's a U.S. subsidiary of Sweden's Studsvik Holding.
  • The plan is to use the company's THOR (Thermal volume/Weight Reduction Technology) to process nuclear power plant waste into solid form rather than a mix of powdery, radioactive resins.
  • Studsvik's patented technology features a pyrolysis / steam reforming system to volume and mass reduce organic waste streams to a non-reactive waste form for efficient Disposal or On-site Storage. Bead Resins, Powdered Filter Medias, Sludges, Activated Charcoal, Non-Metal Filter Cartridges, and Dry Active Wastes (DAW) all have been successfully processed. This entire process is referred to as Thermal Organic Reduction or THOR.

Ten Most Radioactive Places on Earth [26Sep11] - 0 views

  • While the 2011 earthquake and worries surrounding Fukushima have brought the threat of radioactivity back into the public consciousness, many people still don't realize that radioactive contamination is a worldwide danger. Radionuclides are in the top six toxic threats as listed in the 2010 report by The Blacksmith Institute, an NGO dedicated to tackling pollution. You might be surprised by the locations of some of the world’s most radioactive places — and thus the number of people living in fear of the effects radiation could have on them and their children.
  • 10. Hanford, USA
  • The Hanford Site, in Washington, was an integral part of the US atomic bomb project, manufacturing plutonium for the first nuclear bomb and "Fat Man," used at Nagasaki. As the Cold War waged on, it ramped up production, supplying plutonium for most of America's 60,000 nuclear weapons. Although decommissioned, it still holds two thirds of the volume of the country’s high-level radioactive waste — about 53 million gallons of liquid waste, 25 million cubic feet of solid waste and 200 square miles of contaminated groundwater underneath the area, making it the most contaminated site in the US. The environmental devastation of this area makes it clear that the threat of radioactivity is not simply something that will arrive in a missile attack, but could be lurking in the heart of your own country.

  • 9. The Mediterranean
  • For years, there have been allegations that the ‘Ndrangheta syndicate of the Italian mafia has been using the seas as a convenient location in which to dump hazardous waste — including radioactive waste — charging for the service and pocketing the profits. An Italian NGO, Legambiente, suspects that about 40 ships loaded with toxic and radioactive waste have disappeared in Mediterranean waters since 1994. If true, these allegations paint a worrying picture of an unknown amount of nuclear waste in the Mediterranean whose true danger will only become clear when the hundreds of barrels degrade or somehow otherwise break open. The beauty of the Mediterranean Sea may well be concealing an environmental catastrophe in the making.
  • 8. The Somalian Coast
  • The Italian mafia organization just mentioned has not just stayed in its own region when it comes to this sinister business. There are also allegations that Somalian waters and soil, unprotected by government, have been used for the sinking or burial of nuclear waste and toxic metals — including 600 barrels of toxic and nuclear waste, as well as radioactive hospital waste. Indeed, the United Nations’ Environment Program believes that the rusting barrels of waste washed up on the Somalian coastline during the 2004 Tsunami were dumped as far back as the 1990s. The country is already an anarchic wasteland, and the effects of this waste on the impoverished population could be as bad if not worse than what they have already experienced.
  • 7. Mayak, Russia
  • 3. Mailuu-Suu, Kyrgyzstan
  • 6. Sellafield, UK
  • Located on the west coast of England, Sellafield was originally a plutonium production facility for nuclear bombs, but then moved into commercial territory. Since the start of its operation, hundreds of accidents have occurred at the plant, and around two thirds of the buildings themselves are now classified as nuclear waste. The plant releases some 8 million liters of contaminated waste into the sea on a daily basis, making the Irish Sea the most radioactive sea in the world. England is known for its green fields and rolling landscapes, but nestled in the heart of this industrialized nation is a toxic, accident-prone facility, spewing dangerous waste into the oceans of the world.
  • 5. Siberian Chemical Combine, Russia
  • Mayak is not the only contaminated site in Russia; Siberia is home to a chemical facility that contains over four decades' worth of nuclear waste. Liquid waste is stored in uncovered pools and poorly maintained containers hold over 125,000 tons of solid waste, while underground storage has the potential to leak to groundwater. Wind and rain have spread the contamination to wildlife and the surrounding area. And various minor accidents have led to plutonium going missing and explosions spreading radiation. While the snowy landscape may look pristine and immaculate, the facts make clear the true level of pollution to be found here
  • 4. The Polygon, Kazakhstan
  • Once the location for the Soviet Union’s nuclear weapons testing, this area is now part of modern-day Kazakhstan. The site was earmarked for the Soviet atomic bomb project due to its “uninhabited” status — despite the fact that 700,000 people lived in the area. The facility was where the USSR detonated its first nuclear bomb and is the record-holder for the place with the largest concentration of nuclear explosions in the world: 456 tests over 40 years from 1949 to 1989. While the testing carried out at the facility — and its impact in terms of radiation exposure — were kept under wraps by the Soviets until the facility closed in 1991, scientists estimate that 200,000 people have had their health directly affected by the radiation. The desire to destroy foreign nations has led to the specter of nuclear contamination hanging over the heads of those who were once citizens of the USSR.
  • The industrial complex of Mayak, in Russia's north-east, has had a nuclear plant for decades, and in 1957 was the site of one of the world’s worst nuclear accidents. Up to 100 tons of radioactive waste were released by an explosion, contaminating a massive area. The explosion was kept under wraps until the 1980s. Starting in the 1950s, waste from the plant was dumped in the surrounding area and into Lake Karachay. This has led to contamination of the water supply that thousands rely on daily. Experts believe that Karachay may be the most radioactive place in the world, and over 400,000 people have been exposed to radiation from the plant as a result of the various serious incidents that have occurred — including fires and deadly dust storms. The natural beauty of Lake Karachay belies its deadly pollutants, with the radiation levels where radioactive waste flows into its waters enough to give a man a fatal dose within an hour.
  • Considered one of the top ten most polluted sites on Earth by the 2006 Blacksmith Institute report, the radiation at Mailuu-Suu comes not from nuclear bombs or power plants, but from mining for the materials needed in the processes they entail. The area was home to a uranium mining and processing facility and is now left with 36 dumps of uranium waste — over 1.96 million cubic meters. The region is also prone to seismic activity, and any disruption of the containment could expose the material or cause some of the waste to fall into rivers, contaminating water used by hundreds of thousands of people. These people may not ever suffer the perils of nuclear attack, but nonetheless they have good reason to live in fear of radioactive fallout every time the earth shakes.
  • 2. Chernobyl, Ukraine
  • Home to one of the world’s worst and most infamous nuclear accidents, Chernobyl is still heavily contaminated, despite the fact that a small number of people are now allowed into the area for a limited amount of time. The notorious accident caused over 6 million people to be exposed to radiation, and estimates as to the number of deaths that will eventually occur due to the Chernobyl accident range from 4,000 to as high as 93,000. The accident released 100 times more radiation than the Nagasaki and Hiroshima bombs. Belarus absorbed 70 percent of the radiation, and its citizens have been dealing with increased cancer incidence ever since. Even today, the word Chernobyl conjures up horrifying images of human suffering.
  • 1. Fukushima, Japan
  • The 2011 earthquake and tsunami was a tragedy that destroyed homes and lives, but the effects of the Fukushima nuclear power plant may be the most long-lasting danger. The worst nuclear accident since Chernobyl, the incident caused meltdown of three of the six reactors, leaking radiation into the surrounding area and the sea, such that radiative material has been detected as far as 200 miles from the plant. As the incident and its ramifications are still unfolding, the true scale of the environmental impact is still unknown. The world may still be feeling the effects of this disaster for generations to come.

UPDATE: Extremely High Radiation (20,000 CPM) in Ontario After Rainfall [16Aug11] - 0 views

  • UPDATE: Nine Mile Point 2 nuclear facility shut down twice in 1 week due to a "higher than normal leak".  On August 8th the plant was shut down, then again on August 11th.  Nine Mile Point 2 is situated on Lake Ontario and was leaking into it.  Could that be the source of the extremely high radiation found in Toronto area rainwater? 9wsyr.com (WSYR-TV) -- The Nine Mile Nuclear Plant's unit two is back up and running. The plant needed to be shut down twice this week because of leaks, but Friday night all the repairs were complete.
  • Inspections have assured that there are no other issues and the unit is back up to about 24 percent power.   It will take a little more time to get the unit back up to 100 percent.   Representatives say the leaks were never a risk to the public, or to plant employees.

The Death Of The Pacific Ocean [06Dec11] - 3 views

  • An unstoppable tide of radioactive trash and chemical waste from Fukushima is pushing ever closer to North America. An estimated 20 million tons of smashed timber, capsized boats and industrial wreckage is more than halfway across the ocean, based on sightings off Midway by a Russian ship's crew. Safe disposal of the solid waste will be monumental task, but the greater threat lies in the invisible chemical stew mixed with sea water.
  • This new triple disaster floating from northeast Japan is an unprecedented nuclear, biological and chemical (NBC) contamination event. Radioactive isotopes cesium and strontium are by now in the marine food chain, moving up the bio-ladder from plankton to invertebrates like squid and then into fish like salmon and halibut. Sea animals are also exposed to the millions of tons of biological waste from pig farms and untreated sludge from tsunami-engulfed coast of Japan, transporting pathogens including the avian influenza virus, which is known to infect fish and turtles. The chemical contamination, either liquid or leached out of plastic and painted metal, will likely have the most immediate effects of harming human health and exterminating marine animals.
  • Many chemical compounds are volatile and can evaporate with water to form clouds, which will eventually precipitate as rainfall across Canada and the northern United States. The long-term threat extends far inland to the Rockies and beyond, affecting agriculture, rivers, reservoirs and, eventually, aquifers and well water.   Falsifying Oceanography

  • Soon after the Fukushima disaster, a spokesman for the International Atomic Energy Agency (IAEA) at its annual meeting in Vienna said that most of the radioactive water released from the devastated Fukushima No.1 nuclear plant was expected to disperse harmlessly in the Pacific Ocean. Another expert in a BBC interview also suggested that nuclear sea-dumping is nothing to worry about because the "Pacific extension" of the Kuroshio Current would deposit the radiation into the middle of the ocean, where the heavy isotopes would sink into Davy Jones's Locker.
  • The current is a relatively narrow band that acts like a conveyer belt, meaning radioactive materials will not disperse and settle but should remain concentrated   Soon thereafter, the IAEA backtracked, revising its earlier implausible scenario. In a newsletter, the atomic agency projected that cesium-137 might reach the shores of other countries in "several years or months." To be accurate, the text should have been written "in several months rather than years."
  • chemicals dissolved in the water have already started to reach the Pacific seaboard of North America, a reality being ignored by the U.S. and Canadian governments.   It is all-too easy for governments to downplay the threat. Radiation levels are difficult to detect in water, with readings often measuring 1/20th of the actual content. Dilution is a major challenge, given the vast volume of sea water. Yet the fact remains that radioactive isotopes, including cesium, strontium, cobalt and plutonium, are present in sea water on a scale at least five times greater than the fallout over land in Japan.
  • Start of a Kill-Off   Radiation and chemical-affected sea creatures are showing up along the West Coast of North America, judging from reports of unusual injuries and mortality.   - Hundreds of large squid washed up dead on the Southern California coast in August (squid move much faster than the current).   - Pelicans are being punctured by attacking sea lions, apparently in competition for scarce fish.   - Orcas, killer whales, have been dying upstream in Alaskan rivers, where they normally would never seek shelter.
  • - The 9-11 carbon compounds in the water soluble fraction of gasoline and diesel cause cancers.   - Surfactants, including detergents, soap and laundry powder, are basic (versus to acidic) compounds that cause lesions on eyes, skin and intestines of fish and marine mammals.   - Pesticides from coastal farms, organophosphates that damage nerve cells and brain tissue.   - Drugs, from pharmacies and clinics swept out to sea, which in tiny amounts can trigger major side-effects.
  • Japan along with many other industrial powers is addicted not just to nuclear power but also to the products from the chemical industry and petroleum producers. Based on the work of the toxicologist in our consulting group who worked on nano-treatment system to destroy organic compounds in sewage (for the Hong Kong government), it is possible to outline the major types of hazardous chemicals released into sea water by the tsunami.   - Polychlorinated biphenols (PCBs), from destroyed electric-power transformers. PCBs are hormone disrupters that wreck reproductive organs, nerves and endocrine and immune system.   - Ethylene glycol, used as a coolant for freezer units in coastal seafood packing plans and as antifreeze in cars, causes damage to kidneys and other internal organs.
  • Ringed seals, the main food source for polar bears in northern Alaska, are suffering lesions on their flippers and in their mouths. Since the Arctic seas are outside the flow from the North Pacific Current, these small mammals could be suffering from airborne nuclear fallout carried by the jet stream.   These initial reports indicate a decline in invertebrates, which are the feed stock of higher bony species. Squid, and perhaps eels, that form much of the ocean's biomass are dying off. The decline in squid population is causing malnutrition and infighting among higher species. Sea mammals, birds and larger fish are not directly dying from radiation poisoning ­ it is too early for fatal cancers to development. They are dying from malnutrition and starvation because their more vulnerable prey are succumbing to the toxic mix of radiation and chemicals.
  • The vulnerability of invertebrates to radiation is being confirmed in waters immediately south of Fukushima. Japanese diving teams have reported a 90 percent decline in local abalone colonies and sea urchins or uni. The Mainichi newspaper speculated the losses were due to the tsunami. Based on my youthful experience at body surfing and foraging in the region, I dispute that conjecture. These invertebrates can withstand the coast's powerful rip-tide. The only thing that dislodges them besides a crowbar is a small crab-like crustacean that catches them off-guard and quickly pries them off the rocks. Suction can't pull these hardy gastropods off the rocks.
  • hundreds of leather-backed sea slugs washed ashore near Choshi. These unsightly bottom dwellers were not dragged out to sea but drifted down with the Liman current from Fukushima. Most were still barely alive and could eject water although with weak force, unlike a healthy sea squirt. In contrast to most other invertebrates, the Tunicate group possesses enclosed circulatory systems, which gives them stronger resistance to radiation poisoning. Unlike the more vulnerable abalone, the sea slugs were going through slow death.
  • Instead of containment, the Japanese government promoted sea-dumping of nuclear and chemical waste from the TEPCO Fukushima No.1 plant. The subsequent "decontamination" campaign using soapy water jets is transporting even more land-based toxins to the sea.   What can Americans and Canadians do to minimize the waste coming ashore? Since the federal governments in the U.S. (home of GE) and Canada (site of the Japanese-owned Cigar Lake uranium mine) have decided to do absolutely nothing, it is up to local communities to protect the coast.

Impacts of the Fukushima Nuclear Power Plants on Marine Radioactivity - Environmental S... - 0 views

  • 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.

  • We focus on the most complete time-series records from the north and south discharge channels at the Dai-ichi NPPs, and two sites to the south that were not considered sources, namely the north Discharge channels at the Dai-ni NPPs about 10 km to the south and Iwasawa beach which is 16 km south of the Dai-ichi NPPs (Figure 1). The levels at the discharge point are exceedingly high, with a peak 137Cs 68 million Bq m–3 on April 6 (Figure 2). What are significant are not just the elevated concentrations, but the timing of peak release approximately one month after to the earthquake. This delayed release is presumably due to the complicated pattern of discharge of seawater and fresh water used to cool the reactors and spent fuel rods, interactions with groundwater, and intentional and unintentional releases of mixed radioactive material from the reactor facility.
  • the concentrations of Cs in sediments and biota near the NPPs may be quite large, and will continue to remain so for at least 30–100 years due to the longer half-life of 137Cs which is still detected in marine and lake sediments from 1960s fallout sources.
  • If the source at Fukushima had stopped abruptly and ocean mixing processes continued at the same rates, one would have expected that the 137Cs activities would have decreased an additional factor of 1000 from May to June but that was not observed. The break in slope in early May implies that a steady, albeit lower, source of 137Cs continues to discharge to the oceans at least through the end of July at this site. With reports of highly contaminated cooling waters at the NPPs and complete melt through of at least one of the reactors, this is not surprising. As we have no reason to expect a change in mixing rates of the ocean which would also impact this dilution rate, this change in slope of 137Cs in early May is clear evidence that the Dai-ichi NPPs remain a significant source of contamination to the coastal waters off Japan. There is currently no data that allow us to distinguish between several possible sources of continued releases, but these most likely include some combination of direct releases from the reactors or storage tanks, or indirect releases from groundwater beneath the reactors or coastal sediments, both of which are likely contaminated from the period of maximum releases
  • It is prudent to point out though what is meant by “significant” to both ocean waters and marine biota. With respect to prior concentrations in the waters off Japan, all of these values are elevated many orders of magnitude. 137Cs has been tracked quite extensively off Japan since the peak weapons testing fallout years in the early 1960s.(13) Levels in the region east of Japan have decreased from a few 10s of Bq m–3 in 1960 to 1.5 Bq m–3 on average in 2010 (Figure 2; second x-axis). The decrease in 137Cs over this 50 year record reflects both radioactive decay of 137Cs with a 30 year half-life and continued mixing in the global ocean of 137Cs to depth. These data are characteristic of other global water masses.(14) Typical ocean surface 137Cs activities range from <1 Bq m–3 in surface waters in the Southern Hemisphere, which are lower due to lower weapons testing inputs south of the equator, to >10–100 Bq m–3 in the Irish Sea, North Sea, Black Sea, and Baltic Seas, which are elevated due to local sources from the intentional discharges at the nuclear fuel reprocessing facilities at Sellafield in the UK and Cape de la Hague in France, as well as residual 137Cs from Chernobyl in the Baltic and Black Seas. Clearly then on this scale of significance, levels of 137Cs 30 km off Japan were some 3–4 orders of magnitude higher than existed prior to the NPP accidents at Fukushima.
  • Finally though, while the Dai-ichi NPP releases must be considered “significant” relative to prior sources off Japan, we should not assume that dose effects on humans or marine biota are necessarily harmful or even will be measurable. Garnier-Laplace et al.(1) report a dose reconstruction signal for the most impacted areas to wildlife on land and in the ocean. Like this study, they are relying on reported activities to calculate forest biota concentrations,

Bloomberg: Vindicated Seismologist Says Japan Still Underestimates Threat to Reactors [... - 0 views

  • Dismissed as a “nobody” by Japan’s nuclear industry, seismologist Katsuhiko Ishibashi spent two decades watching his predictions of disaster come true: First in the 1995 Kobe earthquake and then at Fukushima. He says the government still doesn’t get it.The 67-year-old scientist recalled in an interview how his boss marched him to the Construction Ministry to apologize for writing a 1994 book suggesting Japan’s building codes put its cities at risk. Five months later, thousands were killed when a quake devastated Kobe city. The book, “A Seismologist Warns,” became a bestseller.That didn’t stop Haruki Madarame, now head of Japan’s Nuclear Safety Commission, from dismissing Ishibashi as an amateur when he warned of a “nuclear earthquake disaster,” a phrase the Kobe University professor coined in 1997. Ishibashi says Japan still underestimates the risk of operating reactors in a country that has about 10 percent of the world’s quakes.
  • “What was missing -- and is still missing -- is a recognition of the danger,” Ishibashi said, seated in a dining room stacked with books in his house in a Kobe suburb. “I understand we’re not going to shut all of the nuclear plants, but we should rank them by risk and phase out the worst.”Among Japan’s most vulnerable reactors are some of its oldest, built without the insights of modern earthquake science, Ishibashi said. It was only in the last four years that Japan Atomic Power Co. recognized an active fault line running under its reactor in Tsuruga, which opened in 1970 about 120 kilometers (75 miles) northeast of Osaka and close to a lake that supplies water to millions of people in the region.New Fault LinesJapan Atomic is reinforcing the plant to improve quake tolerance and believes it’s safe despite the discovery of new active faults lines in 2008, Masao Urakami, a Tokyo-based spokesman for the utility, said.“We can’t respond to every claim by every scientist,” he said. “Standards for seismic ground motion are not decided arbitrarily, but are based on findings by experts assigned by the government.”
  • Reactor 1 at the Tsuruga plant, which had its license extended for 10 years in 2009, is one of 13 on Wakasa bay, a stretch of Sea of Japan coast that is home to the world’s heaviest concentration of nuclear reactors. The area is riddled with fault lines found in the last three or four years, according to Ishibashi.

  • His view changed after a magnitude-6.9 quake killed more than 5,500 people on Jan. 17, 1995, and toppled sections of elevated expressway.After a disaster that Japanese engineers had said couldn’t happen, the nuclear regulator didn’t immediately re-evaluate its construction standards. It said the plants were “safe from the ground up,” as the title of a 1995 Science Ministry pamphlet put it. Ishibashi decided to investigate.The result was an article on Hamaoka published in the October 1997 issue of Japan’s Science Journal that reads like a post-mortem of the Fukushima disaster: A major quake could knock out external power to the plant’s reactors and unleash a tsunami that could overrun its 6-meter defenses, swamping backup diesel generators and leading to loss of cooling and meltdowns.
  • Ishibashi a ‘Nobody’“In the field of nuclear engineering, Mr. Ishibashi is a nobody,” Madarame said in a 1997 letter to the Shizuoka Legislature. Madarame, then a professor at the University of Tokyo school of engineering, is now in charge of nuclear safety in the country.

Medical Journal Article: 14,000 U.S. Deaths Tied to Fukushima Reactor Disaster Fallout ... - 0 views

  • Impact Seen As Roughly Comparable to Radiation-Related Deaths After Chernobyl; Infants Are Hardest Hit, With Continuing Research Showing Even Higher Possible Death Count
  • An estimated 14,000 excess deaths in the United States are linked to the radioactive fallout from the disaster at the Fukushima nuclear reactors in Japan, according to a major new article in the December 2011 edition of the International Journal of Health Services. This is the first peer-reviewed study published in a medical journal documenting the health hazards of Fukushima.Authors Joseph Mangano and Janette Sherman note that their estimate of 14,000 excess U.S. deaths in the 14 weeks after the Fukushima meltdowns is comparable to the 16,500 excess deaths in the 17 weeks after the Chernobyl meltdown in 1986.
  • The rise in reported deaths after Fukushima was largest among U.S. infants under age one. The 2010-2011 increase for infant deaths in the spring was 1.8 percent, compared to a decrease of 8.37 percent in the preceding 14 weeks.The IJHS article will be published Tuesday and will be available online as of 11 a.m. EST at http://www.radiation.org . Just six days after the disastrous meltdowns struck four reactors at Fukushima on March 11, scientists detected the plume of toxic fallout had arrived over American shores. Subsequent measurements by the U.S. Environmental Protection Agency (EPA) found levels of radiation in air, water, and milk hundreds of times above normal across the U.S. The highest detected levels of Iodine-131 in precipitation in the U.S. were as follows (normal is about 2 picocuries I-131 per liter of water): Boise, ID (390); Kansas City (200); Salt Lake City (190); Jacksonville, FL (150); Olympia, WA (125); and Boston, MA (92)

  • Epidemiologist Joseph Mangano, MPH MBA, said: "This study of Fukushima health hazards is the first to be published in a scientific journal. It raises concerns, and strongly suggests that health studies continue, to understand the true impact of Fukushima in Japan and around the world
  • Internist and toxicologist Janette Sherman, MD, said: "Based on our continuing research, the actual death count here may be as high as 18,000, with influenza and pneumonia, which were up five-fold in the period in question as a cause of death. Deaths are seen across all ages, but we continue to find that infants are hardest hit because their tissues are rapidly multiplying, they have undeveloped immune systems, and the doses of radioisotopes are proportionally greater than for adults."Dr. Sherman is an adjunct professor, Western Michigan University, and contributing editor of "Chernobyl - Consequences of the Catastrophe for People and the Environment" published by the NY Academy of Sciences in 2009, and author of "Chemical Exposure and Disease and Life's Delicate Balance - Causes and Prevention of Breast Cancer."The Centers for Disease Control and Prevention (CDC) issues weekly reports on numbers of deaths for 122 U.S. cities with a population over 100,000, or about 25-30 percent of the U.S. In the 14 weeks after Fukushima fallout arrived in the U.S. (March 20 to June 25), deaths reported to the CDC rose 4.46 percent from the same period in 2010, compared to just 2.34 percent in the 14 weeks prior. Estimated excess deaths during this period for the entire U.S. are about 14,000.

North Anna to begin producing electricity today (after $21 million spent in repairs) [... - 0 views

  • The North Anna nuclear plant is expected to begin generating electricity today for the first time since a magnitude-5.8 earthquake shut down both reactors almost three months ago. Dominion Virginia Power started the nuclear-fission process in Unit 1 on Monday at 3 a.m., 2½ days after federal regulators gave permission to return the reactors to service at the power station in Louisa County.
  • The company expects to begin restarting Unit 2 soon after the first reactor begins producing electricity and return both units to full power by Sunday, about 10 days after receiving the green light from the U.S. Nuclear Regulatory Commission. The NRC is monitoring the restart. Its staff reported no concerns Monday. Dominion Virginia Power spokesman Rick Zuercher said the process of restarting the first reactor has taken a little longer than the company had expected but had not encountered significant problems.
  • The Federal Energy Regulatory Commission said Dominion Virginia Power performed a quarterly inspection of the Lake Anna dam last week. "Everything checked out OK," said commission spokeswoman Celeste Miller, who said the company also had inspected the dam immediately after the earthquake.

VA Nuke Plant, Tritium trouble? Nuke fears rise with quake, self-policing [31Aug11] - 0 views

  • After the nuclear catastrophe that followed the earthquake and tsunami in Japan last spring, some Central Virginia activists cautioned that a similar nightmare could unfold right here at the Dominion-operated North Anna nuclear generating plant in Louisa County. Despite Dominion's assurances that the plant made it through the August 23 earthquake unscathed, activists contend that the quake, which measured 5.8 on the Richter Scale and had an epicenter just eleven miles from the plant, may have been more catastrophic than anyone is admitting. New information bolsters their fears.
  • On Monday, August 29, the federal Nuclear Regulatory Commission announced that the quake may, in fact, have produced force that exceeded the North Anna plant's specifications and that the Commission is sending a special Augmented Inspection Team to assess the damage.
  • Initial reviews determined the plant may have exceeded the ground motion for which it was designed," says the release, which also assures that "no significant damage to safety systems has been identified."

  • That's small consolation to one prominent nuclear watchdog, who says it's not what's above ground that gives him the greatest concern. "Central to the issue is miles of buried pipe under the plant that carry radioactive water," says Paul Gunter, director of a nonprofit group called Beyond Nuclear.
  • unter cites recent problems with underground pipes at nuclear plants in Illinois and Vermont, where millions of gallons of water contaminated with the radioactive hydrogen isotope tritium seeped into groundwater, even as the power companies that owned the plants denied for years that it was happening.
  • The result of those leaks and their public concealment by the Exelon and Intergy power companies– at the Braidwood Station plant in Illionis and at the Vermont Yankee Nuclear Power Plant– was not additional government oversight as one might expect, says Gunter, but merely the creation of two voluntary programs that allow the power companies to inspect their own pipes and groundwater and then report the findings to the Commission.
  • Here's an industry that has hidden these leaks that is now self-reporting and overseeing itself to the NRC," says a disgusted Gunter.
  • at North Anna, newly arrived government inspectors won't be conducting their own tests of the miles of underground pipes. And the assumption that those pipes didn't sustain damage during the earthquake, which knocked two Louisa County schools out of commission and caused cracks in the Washington Monument some 90 miles away, might be laughable to Gunter if he weren't convinced of potentially grave public danger.
  • How can an uninspectable, inaccessible buried pipe have integrity?" Gunter asks. "When this Augmented Inspection Team walks onto the site, they'll be walking over the buried pipe that could be leaking." "We have a limited number of inspector resources," acknowledges Commission spokesperson Roger Hannah, who says when it comes to the pipes, inspectors will "make sure we see what [Dominion is] doing."
  • Hannah scoffs at the notion that tritium, already considered by the Commission a much lesser danger than uranium, could leak from damaged pipes into the groundwater and go unnoticed by inspectors. "If you had some issue, you'd see some leakage fairly quickly," says Hannah, noting that no tests have revealed radioactive leakage anywhere at the North Anna.
  • Dominion spokesperson Richard Zuercher also offers reassurance that all is well at North Anna, above and under-ground. "We do have ways to detect if there's any leakage in water," says Zuercher, who says the only damage at the facility was "cosmetic" and didn't affect nuclear function and who insists Dominion will "do whatever is necessary to verify that everything is intact." Gunter, however, says he believes Dominion's not going far enough to protect the public."Given the industry history and what's been done before, Dominion should be distributing bottled water to the town of Mineral and to the residents of Lake Anna," he says. "Indefinitely."
