“There are so few barn swallows left,” Mousseau added. “We know that there were hundreds in a given area before the disaster, and just a couple of years later we’re only able to find a few dozen left.”
“Both the biodiversity and the abundance are showing dramatic impacts in these areas with higher radiation levels, even as the levels are declining.”
For Fukushima Birds, Things are Getting Worse Even as Radiation Abates, Nature World News, By Brian Stallard follow Brian on Twitter @BS_ButNoBS Apr 17, 2015 The destructive earthquake and tsunami that triggered a catastrophe at Japan’s Fukushima-Daiichi nuclear power plant are now four years behind us, but the effects of that disaster are still being felt today. Now a new study has revealed that even as ecosystems slowly recover, Fukushima’s native bird population is actually dwindling more than ever – and researchers think they know why………
“A growing body of empirical results from studies of birds, monkeys, butterflies, and other insects suggests that some species have been significantly impacted by the radioactive releases related to the Fukushima disaster,” Timothy Mousseau, a lead researcher behind one of many ongoing investigations, announced last August.
He explained that a common theme researchers have noticed is that prolonged exposure to low doses of radiation has a very different effect on organisms compared to sudden high-level exposure, as seen at Chernobyl. This came to be called Fukushima’s “insidious effect” and was expected to abate, with lingering radiation levels, by 2016.
Unfortunately, new research detailed in the Journal of Ornithology shows that birds may be facing trouble for even longer. “The declines have been really dramatic,” study author and biologist Tim Mousseau, of the University of South Carolina, said in a recent statement. Continue reading
FPL nuclear plant to draw water from national park’s source, April 17, 2015 | The water in the canal system that cools the reactors at Florida Power & Light Co.’s nuclear plant on the edge of Biscayne Bay is too hot and too salty as temperatures rise and rainfall is sparse.
Starting June 1, as a temporary fix, the company will be allowed to withdraw up to 100 million gallons of fresh water a day from a nearby drainage canal to keep the Turkey Point nuclear plant’s cooling canal system from going above 104 degrees…..http://www.palmbeachpost.com/news/business/fpl-nuclear-plant-to-draw-water-from-national-park/nkw47/
FPL’S NUCLEAR EXPANSION PLAN COULD RUIN THE UNDERLINE. Miami New Times BY JESSICA WEISS APRIL 17, 2015 Biking along a tranquil, green path in South Miami sounds pretty enjoyable. Next to a series of massive, ten-story nuclear power transmission lines? Not so much
That’s a real possibility facing the Underline, a project to transform the underutilized land below Miami’s Metrorail from the Miami River to the Dadeland South Station into a ten-mile urban trail and green space. A design is in the works, and construction is set to begin next year.
But part of the area dedicated to the Underline is also the possible home of new transmission lines for two nuclear reactors being proposed for Turkey Point Nuclear Generating Station by Florida Power & Light. The new reactors would require the construction of massive poles to transmit energy to consumers. And they’d be located on South Dixie Highway from Pinecrest to downtown Miami, within the 125 acres of new green space where the Underline is supposed to run.
“There’s a definite tension between these transmission lines and a beautiful experience on a bike path,” says Meg Daly, the founder of Friends of the Underline…….
Since Daly hatched the idea for the vertical park in 2012, the Underline project has advanced rapidly, receiving funding from the cities of Miami, Coral Gables, and South Miami; the John S. and James L. Knight Foundation; and other groups. In March, Friends of the Underline tapped the codesigner of Manhattan’s popular High Line, James Corner Field Operations, to design the Underline master plan. This week, a series of public meetings are being held to collect public feedback about the design of the space.
“There is so much need in our community for spaces for biking and walking,” Daly says. “Bikes, cars, and pedestrians need to coexist. That is part of a future vision of a walkable, bikeable city.”
Lawmakers, scientists, environmentalists, and citizens have expressed a number of other concerns about expanding nuclear power along Biscayne Bay, including the future impact of sea-level rise, the project’s high costs, and the amount of water used by nuclear power. Miami Mayor Tomás Regalado joined other local leaders this week to blast the project.
But the plan has already passed through local and state levels, and FPL is pursuing a federal license……http://www.miaminewtimes.com/news/fpls-nuclear-expansion-plan-could-ruin-the-underline-7573012

No birdsong in Fukishima: ‘Dramatic’ decline of birds linked to radiation from 2011 disaster
- Researchers find that bird species are continuing to drop in Fukushima
- The barn swallow, for example, dropped from hundreds to dozens
- This is despite radiation levels in the region starting to fall
- And comparing it to Chernobyl could reveal what the future holds
By JONATHAN O’CALLAGHAN FOR MAILONLINE, 16 April 2015
Bird numbers have dramatically declined in Fukushima, research has revealed Scientists analysed 57 species in the region and found that the majority of populations had diminished as a result of the nuclear accident. They found that one breed in particular had plummeted from several hundred before the 2011 disaster to just a few dozen today.
The research, published in the Journal of Ornithology, was carried out by scientists at the University of South Carolina including biologist Dr Tim Mousseau.
They showed that the situation has steadily worsened since the disaster on 11 March 2011………
And while background radiation has declined in the region in recent years, the negative effects of the accident on birds are actually increasing.
‘The relationship between radiation and numbers started off negative the first summer, but the strength of the relationship has actually increased each year,’ Dr Mousseau said.‘So now we see this really striking drop-off in numbers of birds as well as numbers of species of birds.
‘So both the biodiversity and the abundance are showing dramatic impacts in these areas with higher radiation levels, even as the levels are declining.’…….http://www.dailymail.co.uk/sciencetech/article-3041695/No-birdsong-Fukishima-Dramatic-decline-birds-linked-radiation-2011-disaster.html
Fukushima radiation in Canadian waters, DW 10 Apr 15 Scientists have detected radiation from Japan’s 2011 nuclear disaster off the Canadian coast. Experts disagree as to whether the amount detected constitutes a dangerous level or not. Trace amounts of the radioactive isotopes cesium-134 and cesium-137 have been found in samples that were collected close to Vancouver Island in British Columbia. According to the Integrated Fukushima Ocean Radionuclide Monitoring (InFORM) Network, it was the first time that traces of cesium-134 had been detected off North American coasts.
Ken Buesseler, a marine chemist at Woods Hole Oceanographic Institution (WHOI), said in a statement: “Radioactivity can be dangerous, and we should be carefully monitoring the oceans after what is certainly the largest accidental release of radioactive contaminants to the oceans in history.”
He led an initiative that measured 60 sites along the U.S. and Canadian West Coast and Hawaii over the past 15 months for traces of radioactive isotopes from Fukushima. Using computer models, the scientist had already predicted that the traces would reach the coast,……..http://www.dw.de/fukushima-radiation-in-canadian-waters/a-18367257

Statesman Journal, Apr 6, 2015: BREAKING NEWS Scientists detect Fukushima radiation on North American shores — Seaborne radiation from Japan’s Fukushima nuclear disaster has reached North America… cesium-134 and cesium-137 in a sample of seawater taken in February from a dock on Vancouver Island… It’s the first time radioactivity from the March 2011 triple meltdown has been identified on West Coast shores [see: April 2011 — California seawater squeezed from kelp sample had 400,000 Bq/m3 of Iodine-131]… sample was taken Feb. 19… It contained 1.5 becquerels per cubic meter (Bq/m3) of cesium-134, the Fukushima fingerprint, and 5 Bq/m3 of cesium-137 [actually 1.4 and 5.8, respectively]… Fukushimaradiation concerns coastal communities… models have predicted that in general, the plume would hit the shore in the north first, then head south toward California… currents can be unpredictable… Woods Hole has received support from the National Science Foundation to analyze about 250 seawater samples that will be collected next month…
CTVNews, Apr 6, 2015: First low-level trace of Fukushima radioactivity detected off B.C. — But the levels are so low they are likely of little concern… Still, researchers say this is the first detectable of radioactivity from Fukushima found in a water sample taken from the U.S. and Canadian West Coast… Ken Buesseler, a marine chemist at WHOI who has been measuring radioactivity in Pacific seawater since 2011, says it’s been important to carefully monitor the oceans, given that the Fukushima disaster saw the largest accidental release of radioactive contaminants to the oceans in history.
Buesseler’s statement: “Even if the levels were twice as high, you could still swim in the ocean for six hours every day for a year and receive a dose more than a thousand times less than a single dental X-ray. While that’s not zero, that’s a very low risk.. We expect more of the sites will show detectable levels… Predicting the spread of radiation becomes more complex the closer it gets.”
CBC Radio, March 2015: Four years after the nuclear disaster in Fukushima, scientists like UVic’s Jay Cullen are still monitoring the Pacific waters near us for radiation. Listen to what he’s found and what he hasn’t… Cullen: “If we see cesium-134 in a water sample or a fish for example we know that that’s been affected by the Fukushima disaster… Not only is cesium a marker for other isotopes that were released… it also represents a potential radiological health risk because if its internalized… it can damage our cells and cause illness. So the risk of illness appearing in individuals relates to the activity, how much of that isotope ends up in their body. Given the nature of this disaster, with most of the isotopes going into the North Pacific Ocean, the most likely way that a human being would be exposed to this radioactivity at this point would be through the consumption of seafood.” >> Full interview here
Japan mulls releasing radiation into air, instead of water – evaporation instead of Pacific ocean drainage
Japan considers evaporation, storage of tritium-laced Fukushima water TOKYO | BY AARON SHELDRICK (Reuters) 8 Apr 15 – Japan is considering evaporating or storing underground tritium-laced water from the wrecked Fukushima nuclear plant as an alternative to releasing it into the ocean, Tokyo Electric Power Co’s chief decommissioning officer told Reuters on Wednesday.
The removal of hundreds of thousands of tonnes of water containing tritium, a relatively harmless radioactive isotope left behind in treated water is one of many issues facing Tokyo Electric as it tries to cleanup the wrecked plant.Tokyo Electric wants to release the tritium laced water to the ocean, a common practice at normally operating nuclear plants around the world, but is struggling to get approval from local fisherman, who are concerned about the impact on consumer confidence and have little faith in the company.
With the release to the ocean stalled, the government task force overseeing the cleanup is looking at letting the water evaporate or storing it underground, chief decommissioning officer Naohiro Masuda, told Reuters at the close of a seminar on decommissioning.
Masuda said he didn’t know when the discussions would be completed and a decision made.
Time and space is running out for Tepco, which has been forced to build hundreds of tanks to hold contaminated and treated water.
The evaporation method was used after the Three Mile Island disaster but the amounts were much smaller, Dale Klein, an outside adviser to Tepco told Reuters last week.
“They have huge volumes of water so they cannot evaporate it like they did at Three Mile Island,” Klein said. “If they did it would likely be evaporated, go out over the ocean, condense and fall back as rainwater. There’s no safety enhancement.”…….http://www.reuters.com/article/2015/04/08/us-japan-fukushima-water-idUSKBN0MZ0WC20150408

Of the few microorganisms that have been studied, all underwent rapid changes in the areas heavily contaminated by Chernobyl. Organisms such as tuberculosis bacilli; hepatitis, herpes, and tobacco mosaic viruses; cytomegalovirus; and soil micromycetes and bacteria were activated in various ways.
The ultimate long-term consequences for the Chernobyl microbiologic biota may be worse than what we know today. Compared to humans and other mammals, the profound changes that take place among these small live organisms with rapid reproductive turnover do not bode well for the health and survival of other species.
One gram of soil contains some 2,500,000,000 microorganisms (bacteria,microfungi, and protozoa). Up to 3 kg of the mass of an adult human body is made up of bacteria, viruses, and microfungi. In spite of the fact that these represent such important and fundamentally live ecosystems there are only scarce data on the various microbiological consequences of the Chernobyl catastrophe.
Several incidences of increased morbidity owing to certain infectious diseases may be due to increased virulence of microbial populations as a result of Chernobyl irradiation.

Forests Around Chernobyl Aren’t Decaying Properly It wasn’t just people, animals and trees that were affected by radiation exposure at Chernobyl, but also the decomposers: insects, microbes, and fungi By Rachel Nuwer smithsonian.com March 14, 2014 Nearly 30 years have passed since the Chernobyl plant exploded and caused an unprecedented nuclear disaster. The effects of that catastrophe, however, are still felt today. Although no people live in the extensive exclusion zones around the epicenter, animals and plants still show signs of radiation poisoning.
Birds around Chernobyl have significantly smaller brains that those living in non-radiation poisoned areas; trees there grow slower; and fewer spiders and insects—including bees, butterflies and grasshoppers—live there. Additionally, game animals such as wild boar caught outside of the exclusion zone—including some bagged as far away as Germany—continue to show abnormal and dangerous levels of radiation.
However, there are even more fundamental issues going on in the environment. According to a new study published in Oecologia, decomposers—organisms such as microbes, fungi and some types of insects that drive the process of decay—have also suffered from the contamination. These creatures are responsible for an essential component of any ecosystem: recycling organic matter back into the soil. Issues with such a basic-level process, the authors of the study think, could have compounding effects for the entire ecosystem. Continue reading
the abrupt fluctuations offer a glimpse at the duration of the effects of climate change driven by human activity pumping more planet-warming gases into Earth’s atmosphere, Moffitt said.
“What this shows us is that there are major biomes on this planet that are on the table, that are on the chopping block for a future of abrupt climate warming and unchecked greenhouse gas emissions,” Moffitt said. “We as a society and civilization have to come to terms with the things that we are going to sacrifice if we do not reduce our greenhouse gas footprint.
Oceans might take thousands of years to recover from climate change, study suggests, SMH, April 2, 2015 Geoffrey Mohan Naturally occurring climate change lowered oxygen levels in the deep ocean, decimating a broad spectrum of seafloor life that took some 1,000 years to recover, according to a study that offers a potential window into the effects of modern warming.
Earth’s recovery from the last glacial period, in fact, was slower and more brutal than previously thought, according to the study, published online Monday in the journal Proceedings of the National Academy of Sciences.
Researchers deciphered that plotline from a 30-foot core of sea sediments drilled from the Santa Barbara Basin off the coast of California containing more than 5,000 fossils spanning nearly 13,000 years.
“The recovery does not happen on a century scale; it’s a commitment to a millennial-scale recovery,” said Sarah Moffitt, a marine ecologist at the University of California, Davis’ Bodega Marine Laboratory and lead author of the study. “If we see dramatic oxygen loss in the deep sea in my lifetime, we will not see a recovery of that for many hundreds of years, if not thousands or more.”………
beginning around 13,500 years ago, the seafloor community began a slow recovery with the rise of grazers that fed on bacterial mats. Recovery eventually was driven by a fluctuation back toward glaciation during the Younger Dryas period, a cooling sometimes called the Big Freeze.
“The biological community takes 1,000 years to truly recover to the same ecological level of functioning,” Moffitt said. “And the community progresses through really interesting and bizarre states before it recovers the kind of biodiversity that was seen prior to the warming.”……..
The climate changes chronicled in the study arose from natural cycles involving Earth’s orbit of the sun, and the oxygen declines that ensued were more extreme than those that have occurred in modern times, the study noted.
Still, the abrupt fluctuations offer a glimpse at the duration of the effects of climate change driven by human activity pumping more planet-warming gases into Earth’s atmosphere, Moffitt said.
“What this shows us is that there are major biomes on this planet that are on the table, that are on the chopping block for a future of abrupt climate warming and unchecked greenhouse gas emissions,” Moffitt said. “We as a society and civilization have to come to terms with the things that we are going to sacrifice if we do not reduce our greenhouse gas footprint.” http://www.smh.com.au/environment/climate-change/oceans-might-take-thousands-of-years-to-recover-from-climate-change-study-suggests-20150401-1md7qk.html
Fukushima: Uranium and Plutonium Contamination of Large Areas of Oceans, Ground-water, Soils.By Edmondo Burr Global Research, March 29, 2015 Your News Wire Scientists have raised concern over the rate of radioactive contamination of the Pacific, due to the Fukushima nuclear accident.
- Expert : Plutonium-241 from Fukushima nearly 70,000 times more than atomic bomb fallout in Japan.
- Officials : Molten fuel now ‘particle-like’, contains ‘special’ nuclear materials.
- Gov’t Labs : Large areas of oceans contaminated by plutonium from events such as Fukushima; Build-up in biosphere expected; Considerable hazard to humans.
Energy News statement :
Detection of long-lived plutonium isotopes in environmental samples by Accelerator Mass Spectrometry (AMS) — Plutonium isotopes 239Pu, 240Pu and 242Pu are anthropogenic radionuclides emitted into the environment by nuclear activities. Pu is accumulated in the human body and hence, poses a considerable hazard to human health. Due to the long half-lives, these isotopes are present in the biosphere on large time scales and a build-up can be expected. Therefore it is important to study the contamination pathway of Pu into the drinking water… a method to detect long-lived Pu isotopes by Accelerator Mass Spectrometry (AMS) is being developed. AMS requires only few milligrams of sample material… Consequently, more samples from different locations can be taken which is essential when searching for locally increased Pu concentrations as in the Pacific Ocean after the Fukushima accident… Samples from different locations in the Pacific Ocean and from the snow-hydrosphere are planned…

A 2012 report prepared for the Washington State Wine Commission indicates that the state is the “second largest wine producer in the U.S., after California.” Internationally, Washington State is the third-largest exporter of food and agricultural products, according to state officials, with leading products including fresh fruit, vegetables, dairy products, and seafood.
What is not on the Tri-Cities website, however, is a copy of the DOE report released last year that indicated trace amounts of the radioisotope tritium were found in wine samples collected near Hanford in 2013 “that could have potentially originated from the Hanford Site.” Tritium is considered one of the least-threatening radioisotopes because it generally passes from the body quickly, but it still can increase cancer risk because it releases radiation

Soils retain, contain radioactivity in Fukushima Science Daily, March 24, 2015 Source: American Society of Agronomy (ASA), Crop Science Society of America (CSSA)
Radiocesium dissolves easily in water, allowing it to spread quickly. However, different soils have the ability to retain various toxins and prevent them from spreading or entering the food chain. The authors measured the ability of a large number of soil samples collected from Fukushima to intercept radiocesium. They found success depends on various factors.
One key factor is the presence of rough or weathered edges of certain minerals, such as mica, in the soil. These rough edges catch the radiocesium and prevent its movement. This is the frayed edge site (FES) concentration. Nakao explains, however, that “quantification of the FES with a simple experiment has proven difficult.” A “surrogate” measurement used by soil scientists is the radiocesium interception potential (RIP). This measurement is time-consuming and requires specialized facilities, preventing its measure at local institutes.
Thus, Nakao’s study looked for and found that other, more easily measured soil properties to predict the radiocesium interception potential (RIP) of a soil. “These findings may be useful in screening soils that are particularly vulnerable to transferring radiocesium to plants grown in them,” Nakao says. “However, the amounts of radiocesium transferred to plants are normally negligible, because most of the radiocesium is strongly fixed on the frayed edge site.”……..http://www.sciencedaily.com/releases/2015/03/150324101006.htm
