America’s EPA lifting the level of radioactivity permitted in drinking water
EPA Pushing Hike in Radioactive Contamination in Drinking Water http://www.corporatecrimereporter.com/news/200/epa-pushing-hike-in-drinking-water-radioactivity/ By Editor June 7th, 2016
The Environmental Protection Agency (EPA) has unveiled a plan allowing radioactive contamination in drinking water at concentrations vastly greater than the levels permitted by the Safe Drinking Water Act for long periods following release of nuclear materials.
The new guidance would permit radiation exposures equivalent to 250 chest X-rays a year for the general population for an unlimited time period.
EPA’s “Protective Action Guides” (or PAGs) dramatically relax allowable doses of radioactive material in public drinking water following a Fukushima-type meltdown or “dirty bomb” attack.
They cover the “intermediate phase” after “releases have been brought under control” – an unspecified period that may last for weeks, months or even years.
The agency has declared that the strict limits for chemical exposure in the Safe Drinking Water Act “may not be appropriate…during a radiation incident.”
EPA states that it “expects that the responsible party…will take action to return to compliance with the Safe Drinking Water Act maximum contaminant levels as soon as practicable” but during the indefinite meantime –
The general population may be exposed to radioactive iodine-131 at 10,350 pico-curies per liter of water.
By contrast, the current limit is 3, resulting in a 3,450-times increase; The current strontium-90 limit of 8 pico-curies per liter would be allowed a 925-fold increase; and
In an attempt to shield “sensitive populations,” the plan proposes 500 millirem per year for the general population but only 100 millirem for children under 15, pregnant or nursing mothers without explaining how these latter groups will get access to less contaminated water.
“Given this monstrous proposal, it unclear what lessons EPA learned from the contaminated water calamity of Flint, Michigan,” said. Public Employees for Environmental Responsibility (PEER) executive director Jeff Ruch. “It is unfathomable that a public health agency would prescribe subjecting people to radioactive concentrations a thousand times above Safe Drinking Water Act limits as a ‘protective’ measure.”
Internal EPA documents obtained under Freedom of Information Act litigation brought by PEER show that EPA itself concluded that proposed concentrations “would exceed MCLs [Maximum Contaminant Limits of the Safe Drinking Water Act] by a factor of 100, 1000, and in two instances, 7 million.”
The internal analysis estimated for one radionuclide that drinking only one small glass of water “would result in an exposure that corresponds to a lifetime of drinking liters of water per day at the MCL level.”
The Bush Administration in its last days unsuccessfully tried to put forward similar proposals, which the incoming Obama Administration pulled back.
Now, in the waning months of the Obama Administration, those plans are moving forward with new exposure limits higher than the Bush plan it had rejected.
“President Obama goes to Hiroshima to urge a nuclear-free world while his EPA facilitates a nuclear-ridden water supply,” added Ruch. “It speaks volumes that the current Obama drinking water plan is less protective than his predecessor’s.”
Asking how to prepare for a nuclear disaster is asking the wrong question
Nuclear power: Asking the wrong questions http://thebulletin.org/chernobyl-fukushima-and-preparedness-next-one/nuclear-power-asking-wrong-questions Steven Starr, 1 June 16
This is a discussion in which, as Manpreet Sethi has noted, all the participants “either argue in favor of nuclear power or decline to argue against it. … [T]hey see no need to eliminate nuclear energy.” That is, the Bulletin has selected experts who may suggest new policies or technological fixes for the nuclear industry, but will not call for the industry’s abolition.
I am a senior scientist with Physicians for Social Responsibility, a group that does call for abolition. Physicians for Social Responsibility is deeply concerned about the medical and ethical consequences of the ongoing production of enormous amounts of high-level nuclear waste. Such waste, hundreds of thousands of tons of it, sits in “cooling pools” next to nuclear power reactors; many individual pools contain more cesium-137 than was released by all atmospheric nuclear weapons tests combined. These utterly lethal radionuclides will require some form of supervision for hundreds of thousands of years if they are to be prevented from entering the biosphere. Thousands of generations of human beings will have to perform the supervision.
Only one country, Finland, has begun work on a permanent repository for high-level waste, but it is not yet operational. The only permanent site for low-level waste in the United States, the Waste Isolation Pilot Plant in New Mexico, is currently closed due to mishaps including a 2014 radiation release. Hence the entire world provides no good examples of safe permanent storage.
But the problem, of course, extends beyond waste—it includes catastrophic releases of radiation, something that the nuclear industry has not managed to prevent in the first 70 years of its existence. And even Sethi admits that “[t]here can never be a perfect strategy for disaster prevention and preparedness.” So there is little reason to think such releases will be prevented in the future.
When they aren’t prevented, as at Chernobyl, the consequences are devastating, as study after study demonstrates.
- The International Physicians for the Prevention of Nuclear War, in a 2011 report called “Health Effects of Chernobyl,” found that 25 years after the disaster, more than 90 percent of “liquidators”—the soldiers and civilians, numbering at least 740,000, who fought to contain the reactor fire and clean up afterwards—were severely ill or had become invalids.
- According to the UN Scientific Committee on the Effects of Atomic Radiation, between 12,000 and 83,000 genetically damaged children will eventually be born in “affected countries of the Chernobyl region,” while 30,000 to 207,000 such children will be born worldwide due to the disaster. These cases will take time to appear—only 10 percent of the overall expected damage can be seen in the first generation after exposure.
- The “TORCH-2016” report, an independent scientific evaluation of Chernobyl’s health effects based entirely upon peer-reviewed sources, finds that about 5 million people in Belarus, Ukraine, and Russia live in areas still highly contaminated by the Chernobyl disaster (with more than 40 kilobecquerels of cesium-137 per square meter). These areas include 18,000 square kilometers in Belarus, 12,000 square kilometers in Ukraine, and 16,000 square kilometers in Russia. About 400 million people live in less contaminated areas (with between 4 and 40 kilobecquerels of cesium-137 per square meter).
- The unfortunate people who must live on these contaminated lands—especially infants and children—suffer greatly from the effects of the long-lived radionuclides (primarily cesium-137) that have contaminated the forests, soils, and foodstuffs to which they are constantly exposed. In 2011, the National Ministry of Emergencies of Ukraine issued a national report entitled “Twenty-five Years after Chernobyl Accident: Safety for the Future.” The report found that by 2001, no more than 10 percent of the children living in the seriously contaminated zones of Ukraine were considered healthy. Prior to the dispersal of radionuclides from the Chernobyl explosion, 90 percent had been healthy.
These are some of the consequences of a single catastrophic nuclear accident. Fukushima, meanwhile, is an example of the ongoing irradiation of the biosphere. There will be more accidents. The nuclear industry will continue to claim that such accidents pose “no significant danger to human health.” The evidence indicates otherwise.
“If they can get you asking the wrong questions,” Thomas Pynchon wrote in Gravity’s Rainbow, “they don’t have to worry about answers.” Asking how to prepare for a nuclear disaster is asking the wrong question. It steers the conversation away from the real issue, which is why nuclear power reactors should be allowed to continue producing mass quantities of nuclear poison that must be isolated from the biosphere for more than 100,000 years—forever, in human terms. The Chernobyl disaster released only a tiny fraction of the radioactive poison that nuclear power has produced. The overwhelming majority that remains is a grave danger, and to ignore it is willful blindness.
China readies nuclear armed submarines for the Pacific
China to send nuclear-armed submarines into Pacific amid tensions with US
Beijing risks stoking new arms race with move although military says expansion of the US missile defence has left it with no choice, Guardian, Julian Borger , 26 May 16 [ video, excellent graphics] The Chinese military is poised to send submarines armed with nuclear missiles into the Pacific Ocean for the first time, arguing that new US weapons systems have so undermined Beijing’s existing deterrent force that it has been left with no alternative.
Chinese military officials are not commenting on the timing of a maiden patrol, but insist the move is inevitable.
They point to plans unveiled in March to station the US Thaad anti-ballistic system in South Korea, and the development of hypersonic glide missiles potentially capable of hitting China less than an hour after launch, as huge threats to the effectiveness of its land-based deterrent force.
A recent Pentagon report to Congress predicted that “China will probably conduct its first nuclear deterrence patrol sometime in 2016”, though top US officers have made such predictions before…….
Last Tuesday, a US spy plane and two Chinese fighter jets came close to colliding 50 miles of Hainan island, where China’s four Jin-Class ballistic missile submarines are based. A fifth is under construction.
The two countries’ navies have also come uncomfortably close around disputed islands in the same region, and the chance of a clash will be heightened by cat-and-mouse submarine operations, according to Wu Riqiang, an associate professor at the School of International Studies at the Renmin University in Beijing.
“Because China’s SSBNs [nuclear missile submarines] are in the South China Sea, the US navy will try to send spy ships in there and get close to the SSBNs. China’s navy hates that and will try to push them away,” Wu said.
The primary reason Chinese military officials give for the move towards a sea-based deterrent is the expansion of US missile defence, which Moscow also claims is disturbing the global strategic balance and potentially stoking a new arms race.
The decision to deploy Thaad anti-ballistic interceptors in South Korea was taken after North Korea’s fourth nuclear test, and the stated mission of the truck-launched interceptors is to shield the south from missile attack.
But Beijing says the Thaad system’s range extends across much of China and contributes to the undermining of its nuclear deterrent. It has warned Seoul that relations between the two countries could be “destroyed in an instant” if the Thaad deployment goes ahead……
Under Xi’s assertive leadership, China seems determined that the Chinese nuclear deterrent will take finally to the ocean, and it has already taken thestep of putting multiple warheads on its missiles. Those steps are mostly in response to US measures, which in turn were triggered by unrelated actions by the North Koreans.
The law of unintended consequences is in danger of taking the upper hand. “The two sides may thus be stumbling blindly into severe crisis instability and growing competition by China with respect to strategic forces,” Lewis argues. “A competition between unevenly matched forces is inherently unstable.”http://www.theguardian.com/world/2016/may/26/china-send-nuclear-armed-submarines-into-pacific-us
Undersea nuclear deterrence in the Indian Ocean is here to stay
The Indian Ocean Won’t Be a ‘Nuclear Free Zone’ Anytime Soon Undersea nuclear deterrence in the Indian Ocean is here to stay., The Diplomat, By Ankit Panda May 20, 2016 Sartaj Aziz, adviser to Pakistan’s prime minister on foreign affairs, presented an interesting proposal to the Pakistani Senate on Thursday. He said that he would consider having Pakistan introduce a resolution at the United Nations that would urge the body to declare the Indian Ocean a “nuclear free zone.” Leaving aside the fact that the United Nations isn’t in the business of declaring nuclear weapon free zones, Aziz’s comments reflect increasing anxieties in Pakistan about India’s burgeoning sea-based nuclear deterrent.
With the first of Arihant-class of domestically designed ballistic missile submarines rolling out and testing underway of Delhi’s K-4 submarine-launched ballistic missiles ongoing, Delhi is coming closer to operationalizing its sea-based deterrent. (The K-4 has been test launched from the Arihant‘s on-board silos, as I discussed last month.)
Aziz is well aware of these developments. ”Apart from this air defence system, India has also recently conducted tests of nuclear capable, submarine based K4 ballistic missiles. Simultaneously large nuclear powered submarines are being built to carry these nuclear armed missile as a part of its second strike nuclear capability,” he told the Senate, according to a report in Dawn.
Unfortunately, for Pakistan, the United Nations won’t be able to solve this problem anytime soon. Moreover, India won’t be the only country looking to operate nuclear-armed ballistic missile submarines (SSBNs) in the waters of the Indian Ocean. China started operating Song– and Shang-class submarines in the Indian Ocean in 2014, according to the U.S. Department of Defense. Ostensibly, Beijing’s upcoming first overseas military facility—in Djibouti—will play a role in support submarine logistics.
According to the U.S. Defense Department’s most recent report on China’s military, four Chinese Jin-class SSBNs—China’s first sea-based deterrent as well—are operational. These submarines currently operate out off the People’s Liberation Army-Navy’s submarine base at Hainan Island, in the South China Sea, but Beijing may look to have its SSBNs patrolling the Indian Ocean soon enough……
Unsurprisingly, amid increased Chinese sub-surface activity in the Indian Ocean, we’ve seen the United States and India deepen their anti-submarine warfare cooperation. Moreover, Delhi has started extending its maritime patrol and surveillance capabilities further southward; it sent a P-8I Neptune aircraft to the Seychelles earlier this year.
With India’s Arihant-class on the verge of commissioning and Chinese SSBNs possibly on the way to supplement the PLAN’s existing hunter-killer and nuclear attack submarines, the Indian Ocean won’t become a “nuclear free zone” anytime soon. Islamabad could look to build up its own undersea nuclear capabilities, but, as I’ve discussed before, that’ll be limited by a range of factors. http://thediplomat.com/2016/05/the-indian-ocean-wont-be-a-nuclear-free-zone-anytime-soon/
Radium and Lead contaminate rivers From Thousands of Fracking Wastewater Spills
Duke Study: Rivers Contaminated With Radium and Lead From Thousands of Fracking Wastewater Spills. EcoWatch Sharon Kelly, DeSmogBlog | May 9, 2016 Thousands of oil and gas industry wastewater spills in North Dakota have caused “widespread” contamination from radioactive materials, heavy metals and corrosive salts, putting the health of people and wildlife at risk, researchers from Duke University concluded in a newly released peer-reviewed study.
High levels of lead—the same heavy metal that infamously contaminated water in Flint, Michigan—as well as the radioactive element radium, were discovered near spill sites. One substance, selenium, was found in the state’s waters at levels as high as 35 times the federal thresholds set to protect fish, mussels and other wildlife, including those that people eat.
The pollution was found on land as well as in water. The soils in locations where wastewater spilled were laced with significant levels of radium and even higher levels of radium were discovered in the ground downstream from the spills’ origin points, showing that radioactive materials were soaking into the ground and building up as spills flowed over the ground, the researchers said.
The sheer number of spills in the past several years is striking. All told, the Duke University researchers mapped out a total of more than 3,900 accidental spills of oil and gas wastewater in North Dakota alone……. http://ecowatch.com/2016/05/09/radium-lead-fracking/
The 1964 nuclear bomb exploded in South Mississippi – and its effects
In 1964 a nuclear bomb was detonated in South Mississippi http://www.nola.com/health/index.ssf/2016/05/obama_hiroshima_nuclear_bombin.html By Jed Lipinski, NOLA.com | The Times-Picayune The White House announced Tuesday (May 10) that President Barack Obama later this month will visit Hiroshima, Japan, site of the world’s first atomic bombing. It’s the most familiar nuclear explosion in history, but it’s just one of more than 2,000 such explosions — most of them tests — since 1945.
It happened 2,600 feet underground in 1964, when a 5.3-kiloton bomb, one fourth the size of the bomb used on Hiroshima, was detonated deep inside the Tatum Salt Dome in Mississippi. The Tatum Salt Dome explosion was part of a nuclear test to determine whether the U.S. “had the ability to measure Soviet nuclear tests underground in caves,” reporter Mark Schleifstein wrote in The Times-Picayune in 1990.
“The Defense Department and the Atomic Energy Commission — precursor of the Nuclear Regulatory Commission and the Department of Energy — picked as their test site the Tatum Salt Dome southwest of Hattiesburg,” Schleifstein wrote. “It was huge, about a mile across, and relatively remote. Only about 250 families lived within five miles of ground zero.”
Three more blasts — one nuclear, two non-nuclear — followed over the next four years before researchers decided to abandon the site. Officials would later conduct a a massive clean-up effort, dumping 1.3 million gallons of contaminated water and 10,700 cubic yards of contaminated soil into the cavity.
Workers who participated in the clean-up said they were exposed to high levels of radiation on the job. Bill Teck, the chief of security at the site until 1971, was later diagnosed with skin cancer, which a Veterans Administration pathologist attributed to nuclear radiation.
Today, the Mississippi Department of Environmental Quality conducts annual tests of the surface water at the Tatum Dome to monitor slowly dropping levels of tritium, a mildly radioactive type of hydrogen that can seep into water supplies near nuclear power plants.
Respiratory diseases, radioactive fumes – concerns in St Louis County, USA
AIR POLLUTION, ATOMIC RISKS GROW AS TOXIC DUMP SMOLDER , URBAN NEWS SERVICE, Part 2 of a 2 part series. For part 1 visit “Near Ferguson, Ghosts of Hiroshima Haunt Fuming Landfill“.
BRIDGETON, Missouri – They can’t breathe.
Residents of this community near Ferguson — site of 2014’s police-involved shooting death of teenager Michael Brown — have complained for years about lung troubles caused by toxic fumes tied to radioactive waste linked to the atomic bombs that flattened Hiroshima and Nagasaki.
Missouri’s Department of Health and Senior Services will release a study in June to gauge these concerns. Many here call this step positive, small and too late; a slow-moving, subterranean landfill fire that began in 2010, could boost the site’s toxic-gas emissions.
Some locals have been diagnosed with cancer, which they connect to nuclear waste illegally dumped at the West Lake Landfill by the Cotter Corporation in 1973. This radioactive refuse is from World War II’s top-secret Manhattan Project.
Thanks to these conditions, residents who seek government-assisted relocation feel abandoned. Lengthy fights over who ultimately should control the site have slowed cleanup efforts……..
The Centers for Disease Control and Prevention is reportedly investigating the issue following a September 2014 study by Missouri’s health department. It found that, between 1996 and 2011, the ZIP codes around the landfill included statistically significant, higher incidences of leukemia plus cancers of the colon, prostate, kidney, bladder and brain.
“[The] recent study by St. Louis County is actually the first time that a government entity has asked people if they feel ill,” said Laura Barrett, executive director for the Center for Health, Environment and Justice…….
A 1988 Nuclear Regulatory Commission study revealed that its inspectors discovered in 1974 that the Cotter Corporation — which agreed to buy the atomic refuse from the federal government and dispose of it — mixed this waste with 39,000 tons of topsoil. Cotter illegally covered the West Lake Landfill with this irradiated earth in 1973, according to the nuclear agency’s report.
“It’s not in barrels. Some of it’s mixed in the soil and the garbage,” said Chapman. “Some of it’s just lying on the surface for over 40 years, and none of us knew about this.”……https://urbannewsservice.com/investigations/air-pollution-atomic-risks-grow-toxic-dump-smolder/
Ocean’s small shelled animals suffering from acidification due to global warming
Acidic oceans are dissolving shells of tiny sea snails, researchers find, ABC News, 2 May 16 By Kieran Jones Small organisms are struggling to survive as the ocean becomes more acidic, researchers say, including tiny sea snails whose shells are dissolving.
Key points:
- Acidification could severely affect the ocean’s food chain
- Small organisms are being damaged and scientists fear it could affect large animals
- A prominent researcher says reducing CO2 emissions would reduce acidification
Researchers fear an increase in acidification in the Southern Ocean could have a severe impact on the food chain off Australia’s south coast.
The concerns come as 350 scientists from more than 30 countries gather in Hobart for an international symposium on the impact of carbon dioxide on the world’s oceans.
Ocean acidification means the pH level of water has decreased, making it inhospitable for small organisms.
CSIRO research scientist Andrew Lenton was part of a team that developed a map of acidification around Australia.
He said the impact was already being felt.
“The changes in Australia are very close to the changes that are occurring everywhere else in the world, so this is really a global problem that Australia is part of,” he said.
“Already there are detectable changes in the Southern Ocean.”
Reducing carbon dioxide emissions would reduce acidification………The impact is also visible in tiny free-swimming sea snails call pteropods, which are a vital part of the diet of many large fish.
Researchers said the percentage of pteropods with dissolving shells observed had doubled since the pre-industrial era and was on track to triple by 2050.
Dr Richard Feely from the US National Oceanic and Atmospheric Administration (NOAA) said reducing carbon dioxide emissions was the best way to avoid acidification.
“In order for us to address ocean acidification on a global scale we would have to add two billion tonnes of calcium carbonate,” he said………http://www.abc.net.au/news/2016-05-02/acidic-oceans-are-dissolving-shells-on-tiny-sea-snails/7376696?section=environment
Nuclear shipwreck still highly radioactive over 60 years later
Details Emerge from Cold War-Era Nuclear Shipwreck, New Historian, David DeMar May 01, 2016 More details have emerged regarding the wreck of the USS Independence, a US Navy vessel deliberately sacrificed in 1946 at the Bikini Atoll nuclear weapons tests at the very inception of the Cold War…….
NOAA and Boeing used a combination of high-resolution sonar imaging and an unmanned submersible known as “Echo Ranger” to locate and safely survey the still-irradiated wreck of the Independence. The resultant case study, plus newly declassified files on the Navy ship straight from the US National Archives, concerning its time as a nuclear weapons testbed, have been published in theJournal of Maritime Archaeology (JNA)……
merging documentary evidence with a study of the physical remains of a maritime archaeological site is a goal that can and should be pursued…….
The infamous tests at Bikini Atoll, The Bikini tests, conceived and undertaken just one year after dropping not one but two nuclear weapons on Japan, at Hiroshima and Nagasaki, to end the Second World War, was one of the most visible and noteworthy events to signal a fundamental shift in postwar history.
In one of the newly-declassified reports dating from the era, it was suggested that the awesome power of nuclear weaponry represented a new era where the utter destruction of man had become possible, scouring the Earth of nothing but vestigial traces of humanity. http://www.newhistorian.com/details-emerge-cold-war-era-nuclear-shipwreck/6397/
Wildlife continues to suffer seriously from radiation at Chernobyl and Fukushima
Our studies provide new fundamental insights about consequences of chronic, multigenerational exposure to low-dose ionizing radiation. Most importantly, we have found that individual organisms are injured by radiation in a variety of ways. The cumulative effects of these injuries result in lower population sizes and reduced biodiversity in high-radiation areas.
Broad impacts at Chernobyl
Radiation exposure has caused genetic damage and increased mutation rates in many organisms in the Chernobyl region. So far, we have found little convincing evidence that many organisms there are evolving to become more resistant to radiation.
Organisms’ evolutionary history may play a large role in determining how vulnerable they are to radiation. In our studies, species that have historically shown high mutation rates, such as the barn swallow (Hirundo rustica), the icterine warbler (Hippolais icterina) and the Eurasian blackcap (Sylvia atricapilla), are among the most likely to show population declinesin Chernobyl. Our hypothesis is that species differ in their ability to repair DNA, and this affects both DNA substitution rates and susceptibility to radiation from Chernobyl.
Much like human survivors of the Hiroshima and Nagasaki atomic bombs, birds and mammals at Chernobyl have cataracts in their eyes andsmaller brains. These are direct consequences of exposure to ionizing radiation in air, water and food. Like some cancer patients undergoing radiation therapy, many of the birds have malformed sperm. In the most radioactive areas, up to 40 percent of male birds are completely sterile, with no sperm or just a few dead sperm in their reproductive tracts during the breeding season.
Tumors, presumably cancerous, are obvious on some birds in high-radiation areas. So are developmental abnormalities in some plants and insects.
Given overwhelming evidence of genetic damage and injury to individuals, it is not surprising that populations of many organisms in highly contaminated areas have shrunk. In Chernobyl, all major groups of animals that we surveyed were less abundant in more radioactive areas. This includes birds, butterflies, dragonflies, bees, grasshoppers, spiders and large and small mammals.
Not every species shows the same pattern of decline. Many species, including wolves, show no effects of radiation on their population density. A few species of birds appear to be more abundant in more radioactive areas. In both cases, higher numbers may reflect the fact that there are fewer competitors or predators for these species in highly radioactive areas.
Moreover, vast areas of the Chernobyl Exclusion Zone are not presently heavily contaminated, and appear to provide a refuge for many species. One report published in 2015 described game animals such as wild boar and elk as thriving in the Chernobyl ecosystem. But nearly all documented consequences of radiation in Chernobyl and Fukushima have found that individual organisms exposed to radiation suffer serious harm.
There may be exceptions. For example, substances called antioxidants can defend against the damage to DNA, proteins and lipids caused by ionizing radiation. The levels of antioxidants that individuals have available in their bodies may play an important role in reducing the damage caused by radiation. There is evidence that some birds may have adapted to radiation by changing the way they use antioxidants in their bodies.
Parallels at Fukushima
Recently we have tested the validity of our Chernobyl studies by repeating them in Fukushima, Japan. The 2011 power loss and core meltdown at three nuclear reactors there released about one-tenth as much radioactive material as the Chernobyl disaster.
Overall, we have found similar patterns of declines in abundance and diversity of birds, although some species are more sensitive to radiation than others. We have also found declines in some insects, such as butterflies, which may reflect the accumulation of harmful mutationsover multiple generations.
Our most recent studies at Fukushima have benefited from more sophisticated analyses of radiation doses received by animals. In our most recent paper, we teamed up with radioecologists to reconstruct the doses received by about 7,000 birds. The parallels we have found between Chernobyl and Fukushima provide strong evidence that radiation is the underlying cause of the effects we have observed in both locations.
Some members of the radiation regulatory community have been slow to acknowledge how nuclear accidents have harmed wildlife. For example, the U.N.-sponsored Chernobyl Forum instigated the notion that the accident has had a positive impact on living organisms in the exclusion zone because of the lack of human activities. A more recent report of the United Nations Scientific Committee on the Effects of Atomic Radiation predicts minimal consequences for the biota animal and plant life of the Fukushima region.
Unfortunately these official assessments were largely based on predictions from theoretical models, not on direct empirical observations of the plants and animals living in these regions. Based on our research, and that of others, it is now known that animals living under the full range of stresses in nature are far more sensitive to the effects of radiation than previously believed. Although field studies sometimes lack the controlled settings needed for precise scientific experimentation, they make up for this with a more realistic description of natural processes.
Our emphasis on documenting radiation effects under “natural” conditions using wild organisms has provided many discoveries that will help us to prepare for the next nuclear accident or act of nuclear terrorism. This information is absolutely needed if we are to protect the environment not just for man, but also for the living organisms and ecosystem services that sustain all life on this planet……https://theconversation.com/at-chernobyl-and-fukushima-radioactivity-has-seriously-harmed-wildlife-57030
Climate Change threatens the already leaking Marshall Islands radioactive dome
This dome in the Pacific houses tons of radioactive waste – and it’s leaking
The Runit Dome in the Marshall Islands is a hulking legacy of years of US nuclear testing. Now locals and scientists are warning that rising sea levels caused by climate change could cause 111,000 cubic yards of debris to spill into the ocean , Guardian Coleen Jose, Kim Wall and Jan Hendrik Hinzel on Runit Island 3 July 2015
“……..Officially, this vast structure is known as the Runit Dome. Locals call it The Tomb.
Below the 18-inch concrete cap rests the United States’ cold war legacy to this remote corner of the Pacific Ocean: 111,000 cubic yards of radioactive debris left behind after 12 years of nuclear tests.
Brackish water pools around the edge of the dome, where sections of concrete have started to crack away. Underground, radioactive waste has already started to leach out of the crater: according to a 2013 report by the US Department of Energy, soil around the dome is already more contaminated than its contents.
Now locals, scientists and environmental activists fear that a storm surge, typhoon or other cataclysmic event brought on by climate change could tear the concrete mantel wide open, releasing its contents into the Pacific Ocean.
“Runit Dome represents a tragic confluence of nuclear testing and climate change,” said Michael Gerrard, director of the Sabin Center for Climate Change Law at Columbia University, who visited the dome in 2010.
“It resulted from US nuclear testing and the leaving behind of large quantities of plutonium,” he said. “Now it has been gradually submerged as result of sea level rise from greenhouse gas emissions by industrial countries led by the United States.”

Australia’s Great Barrier Reef in grave danger from global warming
Now the scientists have found that the coping mechanism barrier reef corals use to prepare themselves to face warm summer water is also under threat from global warming, and from human activities such as agriculture, shipping, and fishing.
“As temperature warms, the evidence is that this protective mechanism will no longer function
How the Great Barrier Reef is going from bad to worse Christian Science
Monitor, 14 Apr 16 Though the corals of Australia’s Great Barrier Reef historically have managed to adjust to gradually warming seawater of the summer months, they will likely lose their defenses when the ocean warms overall in the near future, say scientists. (at left – coral bleaching )This was the latest finding from a team of American and Australian coral reef experts from James Cook University, the University of Queensland, and the US National Oceanic and Atmospheric Administration (NOAA).
These same scientists recently reported that their aerial surveys of some of the 3,000 coral reefs that make up this iconic natural wonder off Australia’s northeastern coast have showed that coral bleaching this year is the worst that has ever been observed. This is largely due to a recurring weather event known as El Niño, a storm system that is expected to become more frequent and more severe in the future.
I agree that El Niño is a natural variability; it’s a part of nature, but that variation in patterns and temperatures is superimposed upon a trend of warming,” Scott Heron, a NOAA coral reef scientist based in Australia, tells The Christian Science Monitor in an interview. “There are ups and downs, but now there are just higher ups than ever before, and the downs are not as low,” he says.
Coral bleaching happens when ocean temperatures rise to a point that zooxanthellae – tiny algae that live on corals and provide them with nutrients and their radiant colors – leave their coral homes, thereby rendering coral white or “bleached.” When corals go without zooxanthellae for too long, they die. This affects about a quarter of marine species that depend on coral reefs for shelter, and the humans who depend on those species for their livelihoods.
This year’s is the third major bleaching event in recent history for the 2,300-kilometer-long Great Barrier Reef, which is home to one of the most diverse ecosystems in the world. But this one is much worse than the bleaching events that occurred in 1998 and 2002, say scientists who recently found bleaching in almost 1,100 kilometers of northern barrier reef, from the island of New Guinea to the Australian coastal city of Cairns. The researchers estimate that 30 to 50 percent of the corals there are already be dead.
Now the scientists have found that the coping mechanism barrier reef corals use to prepare themselves to face warm summer water is also under threat from global warming, and from human activities such as agriculture, shipping, and fishing.
“As temperature warms, the evidence is that this protective mechanism will no longer function,” C. Mark Eakin, a scientist with NOAA Coral Reef Watch, tells the Monitor in an interview…….
The most viable immediate remedy, say paper authors, is to reduce the carbon emissions that cause warming and restrict other human activities near the reefs that add more stress, including runoff from agriculture, unsustainable fishing practices, and physical damage to the reef from ship groundings.

Fukushima – the irradiation of a nation
Top Official: Over 60 million Japanese irradiated by Fukushima — Nuclear Expert: 50,000 sq. miles of Japan highly contaminated… Many millions need to be evacuated… Gov’t has decided to sacrifice them, it’s a serious crime — TV: More than 70% of country contaminated by radiation (VIDEOS) http://enenews.com/top-official-60-million-japanese-irradiated-fukushima-nuclear-expert-50000-square-miles-country-highly-contaminated-many-millions-be-evacuated-govt-decided-sacrifice-serious-crime-professor-70-l?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29
Interview with nuclear engineer Hiroaki Koide (translation by Prof. Robert Stolz, transcription by Akiko Anson), published Mar 8, 2016 (emphasis added): [Radioactive] material has been dispersed, contaminating Tohoku, Kanto [Tokyo area], and western Japan… [The law says] that absolutely nothing may be removed from a radioactive management area in which the levels exceed 40,000 Becquerels per square meter… [H]ow much area has been contaminated beyond 40,000 Bq/m2… that answer is 140,000 km^2 [54,054 square miles]… Indeed, while centered on Fukushima, parts of Chiba and Tokyo have also been contaminated. The number of people living in what must be called a radiation-controlled area is in the millions, and could exceed ten million… I believe the government has the responsibility to evacuate these entire communities… the government decided to leave them exposed to the real danger of radiation. In my view, Fukushima should be declared inhabitable… but if that were to be done, it would likely bankrupt the country… They’ve decided to sacrifice people… In my view, this is a serious crime committed by Japan’s ruling elite… [F]undamentally, people must not be forced to live in contaminated areas… First must come complete evacuation… [W]hen it comes to radiation… “removal of contaminants” is impossible… This stuff contaminates everything.
Naoto Kan, former Prime Minister of Japan, Apr 11, 2016 (at 2:15 in): The molten material broke through the pressure vessel and accumulated low down in the containment. Now what would have happened if this molten material had escaped from the containment?… A radius of 250 kilometers — which includes the city of Tokyo — anyone living in this area, if you count them up it comes to 50 million or 40% of the Japanese population, and they would all have had to be evacuated. As we know from Chernobyl, not just a couple of weeks, but 30 years or 40 years — it would have virtually meant the end of Japan. [Note: Many nuclear experts believe the molten fuel did in fact escape from the containment] Half the population was subject to radiation [Japan Population: 127 million]. That’s something that could just be imagined, for instance the event of losing a major war.
Arirang (Gov’t-funded Korean TV network), ‘Fukushima and Its Aftermath’, Mar 16, 2016 (at 6:45 in) —Prof. Kim Ik-Jung, Medical College at Dongguk Univ.: “When you look at the contamination map, about 70% of Japan is contaminated by radiation. That means that 70% of Japan’s agricultural and marine products are contaminated.”… According to PNAS, one of the five major scientific journals, over 70% of the land in Japan is contaminated by radiation.
Rapid collapse of ice shelves in Antarctica
Scientists Are Watching in Horror as Ice Collapses Everything we learn about ice shows that it is disturbingly fragile, even in Antarctica. National Geographic, By Douglas Fox APRIL 12, 2016 “……..The catastrophic collapse of Larsen A and several other ice shelves along the Antarctic Peninsula has yielded important lessons about the vulnerability of Antarctica’s ice sheets to a warming climate. A new analysis of ice sheet instability, published March 31 in Nature, took the public by surprise when it projected that global sea level might rise six feet by 2100, and as much as 40 to 50 feet by the year 2500. (Read “Why the New Sea Level Alarm Can’t Be Ignored.”) That study seemed to double, overnight, the amount of sea level rise that can be expected. But many glacial scientists weren’t surprised. The new estimate is based on insights that have emerged slowly, over 20 years, in the aftermath of these ice shelf collapses.
The Aftermath of an Ice Shelf Collapse
Explore the fjords along the northeastern Antarctic Peninsula today, and it’s easy to find landscapes that look scarred even to the casual observer. …..
The glacier, now absent, had retreated several miles into its fjord. The fjord used to hold 2,000 feet (600 meters) of ice. Now it held 2,000 feet of seawater instead.
The aftermath of an ice shelf collapse is obvious in Sjögren’s fjord. When the ice shelf in front of Sjögren disintegrated in 1995, it removed the buttress that stabilized the glacier. The glacier started sliding into the sea at twice its original speed. Sjögren erupted in crevasses and thinned by several hundred feet as it stretched. After a few years, the glacier had retreated miles into its fjord as icebergs splintered off the glacier’s front faster than the ice could flow forward…….
Every ice shelf that disintegrated along the Antarctic Peninsula has shown the same pattern: summer melting of its top layers, winter refreezing of those top layers into icy crusts able to hold large melt ponds, and the re-exposure of long-buried crevasses.
For all of these ice shelves, the moment of death occurred suddenly. Each collapse began when water from the melt ponds drained into the crevasses. The weight of the water drove the cracks deeper—like a wedge, says Ted Scambos, a glaciologist with the National Snow and Ice Data Center at the University of Colorado in Boulder, who discovered the process. These fluid wedges eventually broke through the bottom of the ice shelf, calving off one iceberg, then another and another—a process called hydrofracturing that can devour an ice shelf nearly the size of Rhode Island in a matter of hours or days……..
Ice loss may have begun at a narrow beachhead in Antarctica, at the north end of the Antarctic Peninsula, but it has expanded on multiple fronts, as new regions of ice come into play every several years. As warm summer temperatures push farther south, so will the problems of melt ponding, ice shelf disintegration, and ice cliff collapse, which drive the rapid retreat of ice. (Read more about how calving causes mini-tsunamis daily in Antarctica.)
Scattered melt ponds already appear on some of the ice shelves that surround the Antarctic mainland, much farther south than any that have collapsed so far. The amount of ice lost each year from all of Antarctica’s ice shelves has increased 12-fold between 1994 and 2012.
Aside from warm air, the fringes of Antarctica’s ice are under assault from another source—warming ocean currents that melt the undersides of ice shelves.

Florida drinking water wells threatened by nuclear plant leak
Nuclear Plant Leak Threatens Drinking Water Wells in Florida, NYT By LIZETTE ALVAREZ MARCH 22, 2016 MIAMI — When Florida’s largest power company added two nuclear reactors to an existing plant that sat between two national parks — Biscayne Bay and the Everglades — the decision raised the concerns of environmentalists and some government officials about the possible effects on water quality and marine life.
Now more than four decades later, Florida Power & Light’s reactors atTurkey Point, built to satisfy the power needs of a booming Miami, are facing their greatest crisis. A recent study commissioned by the countyconcluded that Turkey Point’s old cooling canal system was leaking polluted water into Biscayne Bay.
This has raised alarm among county officials and environmentalists that the plant, which sits on the coastline, is polluting the bay’s surface waters and its fragile ecosystem. In the past two years, bay waters near the plant have had a large saltwater plume that is slowly moving toward wells several miles away that supply drinking water to millions of residents in Miami and the Florida Keys.
Samples of the water at various depths and sites around the power plant showed elevated levels of salt, ammonia, phosphorous and tritium……
last month, a Florida administrative judge, Bram Canter, chastised the state and Florida Power & Light, finding that the cooling canal system is “the major contributing cause” for the growth of the large underground saltwater plume and for its westerly move toward the drinking water well fields. He ordered the state and the company to clean up the cooling canals, which it had started to do under an October consent decree with the county.
The Biscayne Aquifer, the judge noted in his ruling, is an “important natural resource.” It is the main source of drinking water in the county and is vital to irrigation and the marsh wetland communities, he added. Judge Canter made his ruling after a Florida rock mining company sued the company over the saltwater plume. http://www.nytimes.com/2016/03/23/us/nuclear-plant-leak-threatens-drinking-water-wells-in-florida.html?ref=energy-environment&_r=1
