US Thirst for Fossil Fuels is Decimating Nature's Wildlife: Report [19Jan12] - 0 views

  • The day after the Obama administration rejected a proposal for the Keystone XL tar sands pipeline -- a move widely, if cautiously, applauded by environmental groups and advocates of renewable energy -- a new report highlights the destructive impact of fossil fuel consumption in the United States. The report, called Fueling Extinction: How Dirty Energy Drives Wildlife to the Brink, highlights the top 10 US species whose survival is most threatened by the development, extraction, transportation, and consumption of fossil fuels.
  • The report itself does not shy away from pointing its finger directly at the profit-driven aspect of the fossil fuel industry, nor its dependence on taxpayer-funded subsidies:
  • The animals (and one plant) highlighted by the group range from the relatively unknown and small Tan Riffleshell, a freshwater mussel found in only five rivers in the eastern US, to the large and majestic Bowhead Whale, believed to be among the oldest mammals on earth and the only whale that lives exclusively in arctic waters.  The other eight species examined in the report include: the Dunes Sagebrush Lizard, the Graham’s Penstemon (a wildflower), the Greater Sage Grouse, the Kemp’s Ridley Sea Turtle, the Kentucky Arrow Darter, the Spectacled Eider, the Whooping Crane, and the Wyoming Pocket Gopher. Receiving the 'activist's choice award' from the voting members was the Polar Bear, chosen because it was "the species they were most concerned about."

  • 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.

Mutton bird radiation warning - ABC News (Australian Broadcasting Corporation) [30Sep11] - 0 views

  • Tasmanians are being warned not to collect dead mutton birds for research.A recent Tasmanian Farmers and Graziers Association newsletter describes research into mutton bird exposure to radiation from Japan's Fukushima nuclear plant. It says the birds will soon be migrating back to Australia after many spent winter in the Sea of Japan. The article says people can help researchers by collecting freshly dead mutton birds, freezing them and handing them over to their local Parks and Wildlife office or museum. But the department says it is not seeking samples and discourages people unfamiliar with wildlife from collecting them. A spokeswoman says suggestions of radiation exposure in birds is being further investigated.

Alaska ringed seals show symptoms of unknown disease; animals come to shore with lesion... - 0 views

  • An unknown disease is killing or weakening scores of ringed seals along Alaska’s north coast, where the animals have been found with lesions on their hind flippers and inside their mouths. Ringed seals, the main prey of polar bears, and a species that rarely comes ashore, in late July began showing up on the Beaufort Sea coast outside Barrow with the lesions, patchy hair loss and skin irritation around the nose and eyes. The outbreak was reported first in the Alaska Dispatch.
  • Officials from the National Marine Fisheries Service and the North Slope Borough said Thursday that 107 animals were found stranded from late July through Sept. 29 and 99 appeared to have lesions. Nearly half died. “Forty-six of the animals were dead when found, or died shortly thereafter,” said Julie Speegle, spokeswoman for the National Marine Fisheries Service. Seals still alive were lethargic or showing labored breathing.Necropsies revealed lesions were not limited to skin of seals. Biologists studying the dead animals found lesions in the respiratory system, liver, lymphoid system, heart and brain, she said.
  • Wildlife authorities in Canada and Russia have reported similar incidents, she said. “We don’t know if they’re related, but they’re similar,” Speegle said.Linda Deger, a spokeswoman for Fisheries and Oceans Canada, said by email that ringed seals are the only species reported to be affected and the department and other agencies are investigating. “At this point, we don’t know exactly what is causing it,” Speegle said. “Laboratory findings have been inconclusive to date but samples have tested negative for pox virus, herpes virus, papillomavirus, morbillivirus and calicivirus.”

  • It’s also not known whether symptoms could be transferred to other animals or humans, she said, although officials are keeping a close watch.A press release from the North Slope Borough said the strandings included animals as far west as Point Lay and Wainwright on the Chukchi Sea. That outbreak, the borough said, appeared to peak in mid-August. Several dead walruses were examined at Point Lay with skin lesions and hunters reported lesions on two bearded seals, the borough said.Jason Herreman of the borough’s Department of Wildlife Management said villagers have been warned not to eat stricken seals. Most ringed seal hunting by borough communities is done in the spring. “We’ve been talking to our hunters since this first came to our attention in July,” he said by phone from Barrow. “By that time the majority of seal hunting was done for the year.”The National Oceanic and Atmospheric Administration in December proposed listing ringed seals as a threatened species because of the projected loss of snow cover and sea ice from climate warming. Sea ice and snow are crucial for ringed seal breeding.

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,

Is radiation causing Arctic Alaska ringed-seal deaths? [27Dec11] - 0 views

  • The University of Alaska Fairbanks' Institute of Marine Sciences is launching an investigation into whether radiation, including possibly from the Fukoshima Daiichi nuclear power-plant disaster in Japan, has harmed or killed more than 100 ringed seals off Alaska's coasts. More than 60 dead and 75 diseased seals have shown up mostly on Alaska's Arctic beaches since this July, with symptoms that include oozing skin sores, patchy hair loss and damaged organs, prompting a wide-ranging investigation into the mysterious cause of their illness. Scientists are considering several possible causes. But much of the effort has been geared toward finding the bacteria or virus that's causing the apparently unprecedented symptoms, with labs nationally and in other countries examining tissue from ringed seals and Alaska walrus, which appear to be suffering the same affliction.
  • The work so far has yielded at least one important clue: "Tests indicate a virus is not the cause," said a recent press release from NOAA and the U.S. Fish and Wildlife Service. Some wonder if radiation could be causing the skin sores and related problems, including ulcers on internal organs and abnormal growths on brains.
  • John Kelley, with the Institute of Marine Sciences at UAF, said he's just received a large batch of tissue from afflicted ringed seals and will soon begin the university's hunt for radiation as a possible cause.

  • Is it possible that the ringed seals traveled to a contaminated area? They do, after all, have quite a range. Experts could not be reached the Friday before Christmas to explain migratory routes for Alaska's estimated stock of 250,000 ringed seals. Or did they eat prey contaminated by radiation? If there is a link to Fukoshima, the lab will find it, said Kelley.

The myth of renewable energy | Bulletin of the Atomic Scientists - 0 views

  • "Clean." "Green." What do those words mean? When President Obama talks about "clean energy," some people think of "clean coal" and low-carbon nuclear power, while others envision shiny solar panels and wind turbines. And when politicians tout "green jobs," they might just as easily be talking about employment at General Motors as at Greenpeace. "Clean" and "green" are wide open to interpretation and misappropriation; that's why they're so often mentioned in quotation marks. Not so for renewable energy, however.
  • people across the entire enviro-political spectrum seem to have reached a tacit, near-unanimous agreement about what renewable means: It's an energy category that includes solar, wind, water, biomass, and geothermal power.
  • Renewable energy sounds so much more natural and believable than a perpetual-motion machine, but there's one big problem: Unless you're planning to live without electricity and motorized transportation, you need more than just wind, water, sunlight, and plants for energy. You need raw materials, real estate, and other things that will run out one day. You need stuff that has to be mined, drilled, transported, and bulldozed -- not simply harvested or farmed. You need non-renewable resources:
  • ...15 more annotations...
  • Solar power. While sunlight is renewable -- for at least another four billion years -- photovoltaic panels are not. Nor is desert groundwater, used in steam turbines at some solar-thermal installations. Even after being redesigned to use air-cooled condensers that will reduce its water consumption by 90 percent, California's Blythe Solar Power Project, which will be the world's largest when it opens in 2013, will require an estimated 600 acre-feet of groundwater annually for washing mirrors, replenishing feedwater, and cooling auxiliary equipment.
  • Geothermal power. These projects also depend on groundwater -- replenished by rain, yes, but not as quickly as it boils off in turbines. At the world's largest geothermal power plant, the Geysers in California, for example, production peaked in the late 1980s and then the project literally began running out of steam.
  • Wind power. According to the American Wind Energy Association, the 5,700 turbines installed in the United States in 2009 required approximately 36,000 miles of steel rebar and 1.7 million cubic yards of concrete (enough to pave a four-foot-wide, 7,630-mile-long sidewalk). The gearbox of a two-megawatt wind turbine contains about 800 pounds of neodymium and 130 pounds of dysprosium -- rare earth metals that are rare because they're found in scattered deposits, rather than in concentrated ores, and are difficult to extract.
  • Biomass.
  • t expanding energy crops will mean less land for food production, recreation, and wildlife habitat. In many parts of the world where biomass is already used extensively to heat homes and cook meals, this renewable energy is responsible for severe deforestation and air pollution
  • Hydropower.
  • "renewable energy" is a meaningless term with no established standards.
  • The amount of concrete and steel in a wind-tower foundation is nothing compared with Grand Coulee or Three Gorges, and dams have an unfortunate habit of hoarding sediment and making fish, well, non-renewable.
  • All of these technologies also require electricity transmission from rural areas to population centers. Wilderness is not renewable once roads and power-line corridors fragment it
  • the life expectancy of a solar panel or wind turbine is actually shorter than that of a conventional power plant.
  • meeting the world's total energy demands in 2030 with renewable energy alone would take an estimated 3.8 million wind turbines (each with twice the capacity of today's largest machines), 720,000 wave devices, 5,350 geothermal plants, 900 hydroelectric plants, 490,000 tidal turbines, 1.7 billion rooftop photovoltaic systems, 40,000 solar photovoltaic plants, and 49,000 concentrated solar power systems. That's a heckuva lot of neodymium.
  • hydroelectric power from dams is a proved technology. It already supplies about 16 percent of the world's electricity, far more than all other renewable sources combined.
  • None of our current energy technologies are truly renewable, at least not in the way they are currently being deployed. We haven't discovered any form of energy that is completely clean and recyclable, and the notion that such an energy source can ever be found is a mirage.
  • Long did the math for California and discovered that even if the state replaced or retrofitted every building to very high efficiency standards, ran almost all of its cars on electricity, and doubled its electricity-generation capacity while simultaneously replacing it with emissions-free energy sources, California could only reduce emissions by perhaps 60 percent below 1990 levels -- far less than its 80 percent target. Long says reaching that target "will take new technology."

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.

Idaho Samizdat: Nuke Notes: Scots drop out of UK nuclear new build [29Sep11] - 0 views

  • Scottish & Southern Energy (LON:SSE) has taken its ball and glove and marched off the field leaving an alliance, called NuGen, with GDF Suez and Iberdrola to build new nuclear reactors in the U.K. The other two investors bought out Scottish & Southern's shares, worth 25% of the project, for an undisclosed price increasing their respective stakes to 50% each. SSE said would now focus on renewable energy projects and with natural gas plants fueled by North Sea fields to keep the transmission lines humming when the wind doesn't blow. This may be the utility's real comfort zone and some question whether it ever really had its heart in the effort to invest in the nuclear field.
  • According to a Bloomberg wire service report for Sept 22, Investec analyst Angelos Anastasiou said, "Renewables are their favored area and where they see themselves in the forefront. The nuclear side was always half-hearted." Cheers from the post-industrial greens
  • Meanwhile, in Scotland, post-industrial visionary green groups cheered SSE's decision. In widely reported rhetoric, Dan Barlow, a key figure at Scotland's World Wildlife Fund (WWF), said his organization welcomed SSE's abandonment of the nuclear project. And he went further calling on the remaining investors to give up their nuclear plans as well. The government in Scotland, like Germany, has a delusional vision that it can provide up to 80% of its electricity needs with offshore wind power. Scotland's energy minister Fergus Ewing echoed the statements of the WWF signaling perhaps a closer than expected relationship between green groups and the government. It raises the question of whether SSE made its decision to pull out based solely on financial risk or whether it was pushed into a retreat. Ewing claims that the decision by SSE to pull out of a consortium to build a nuclear reactors is a "vindication" of one of the Scottish Government's policies to promote renewable energy.
  • ...1 more annotation...
  • Alistair Phillips-Davies, a spokesman for SSE, told financial wire services is was the money, and not politics, that drove the decision. "We have concluded, that for the time being, our resources are better deployed on business activities and technologies where we have the greatest knowledge and experience." SSE had put money on the table to get into the nuclear game. With its two partners at NuGen, in 2009 the alliance bought the government approved site for the planned reactors for £70 million ($109 million). At a 25% share, that works out to a commitment of about £18 million or around $27 million. This may sound like a lot of money, but SSE has a market cap of just over £12 billion which makes the site acquisition costs a sneeze on a summer day.

  • The Fukushima nuclear accident in Japan has taken a massive toll on animals. The fate of wildlife is largely unknown, but domestic pets and livestock continue to suffer.   Livestock were forcibly abandoned and left behind to starve. Cows contaminated with cesium five times the permissible level have been slaughtered. Buried in the ground, their radioactive carcasses will continue to contaminate the land for decades if Chernobyl is any indication.   Family pets were left behind, tied, abandoned in homes, or left to roam the streets in search of food. Their owners were forbidden to return or were allowed to make brief visits to feed them, often too late. A rabbit born without ears is stoking fears of birth defects and genetic damage among humans while whales have been caught that are found to be contaminated with radioactive cesium. In the event of US reactor accidents, citizens are encouraged to evacuate with their pets. However, evacuation shelters and most hotels do not allow animals. Livestock, of course, cannot be evacuated.

Earless baby bunny near Fukushima Daiichi stokes fears of radiogenic mutation... - 0 views

  • A baby bunny apparently born without ears (photo at left) in the town of Namie, near the massively leaking Fukushima Daiichi nuclear power plant, has raised concerns about mutagenic effects caused by radioactivity in the environment. Naysayers abound, despite evidence of genetic mutations in animals (such as a two headed calf) and plants (including deformed flowers) in the aftermath of the Three Mile Island meltdown collected and documented by Mary Osborn; numerous scientific studies showing adverse impacts on wildlife populations in Chernobyl contaminated regions, such as on birds by Dr. Tim Mousseau of the University of South Carolina; and, further back in time, an epidemic of ewe deaths in southwest Utah immediately downwind of the Nevada Nuclear Weapons Test Site. An excellent book by John G. Fuller, "The Day We Bombed Utah," published in 1984, recounts how Mormon sheep farmers experienced unprecedented sheep and ewe deaths in the early 1950s, shortly after nuclear weapons blasts upwind in Nevada. The farmers sued the Atomic Energy Commission for damages. AEC research scientists swore, under oath, that they had no evidence that radioactivity could cause such a die off in sheep and ewes. However, over a quarter century later, it was shown by the sheep farmers and their attorney that the AEC had lied -- they had conducted experiments on sheep at the Hanford Nuclear Reservation in Washington State: they observed die offs very similar to what occurred in Utah. The same judge who had presided over the original trial heard the new evidence as well, and ruled that the AEC had perpetrated a fraud upon the court. Fuller also wrote "We Almost Lost Detroit," published in 1975, about the 1966 partial meltdown at the Fermi 1 experimental plutonium breeder reactor in Monroe, Michigan.
