THIS IS WHAT THE REAL FUKUSHIMA AND LARGE SURROUNDING AREA IS LIKE.
Ken 26 June 18 Only is it much much worse and, more insidious. There are multiple deadly cesium 137 like rdionuclides in Northern Japan. There are thousands of times more life extinguishing radionuclides as evil and potent as the 19 gms of cesium137 in brazil, that destroyed a community and several generations of families.
It is in the water, the soil, the food, the air, the people, their houses, the animals, the plants, their cars. It is everywhere.in Japan.
From the Beyond Nuclear story abput the cesium 137 tragedy in Brazil:
On September 13, 1987, Brazilian scrap metal dealer, Devair Ferreira, unwittingly opened Pandora’s box. Out spilled a bright blue crystalline powder that fell glowing to the floor. Fascinated by the magical iridescence, Ferreira invited family members to his home to see the mysterious substance for themselves. They were entranced. They touched it and passed it around to other friends and relatives.
What none of them knew was that they had just set in motion Latin America’s worst nuclear accident. The blue powder was cesium chloride, encased inside a cesium-137 teletherapy unit that had been left behind in an abandoned cancer treatment hospital in the City of Goiânia, the capital of the State of Goiás. Two jobless youngsters had picked it up, pulled out the heavy lead cylinder containing 19 grams of cesium-137, and sold it to Ferreira.
Ferreira, and his friends and family, soon became sick. His brother Ivo took some of the powder to his house where his six-year old daughter Leide played with the glowing radioactive crystals on the floor just before dinner. When she ate boiled eggs with her contaminated fingers, the deadly cesium-137 entered her body. Twenty two Ferreira family members had direct contact with the cesium-137. But they unwittingly went on to contaminate others.
It is amazing how much damage, 19 gr
Of this evil blue shit cesium 137 did in this town in Brazil. The shit, like cobalt 60, strontium 90, iridium is such a strong gamma emitter it has to be tightly contained in a thick lead box. Yet tons of it and other shit was blown all over japan by the reactor explosions.Decontamination of houses and streets in Goiânia
At least 40 people were hospitalized, and by October 28 four had died. They were Ivo’s daughter Leide and Devair Ferreira’s wife Gabriela — who had first sounded the alarm about the sudden mysterious sicknesses in her extended family — along with two of Devair’s employees.
All of those affected were at first treated at the local hospital like regular patients and were allowed to circulate freely through the city, contaminating others they met, as well as the doctors and nurses who cared for them. For 16 days, no one knew that the cause of their sickness was radiation exposure.
When it finally came to light, Brazil’s National Nuclear Energy Commission sent a team to Goiânia, to quarantine and isolate those contaminated and to start the clean-up.
A total of 112,800 people remained isolated in the Olympic Stadium of Goiânia until December 1987, and were examined there for radiation by the CNEN. Radiation technicians ultimately registered a total of 249 contaminated people, 129 of them with cesium-137 in their body, a man-made isotope produced in nuclear reactors that, when ingested, binds with muscle and irradiates people internally.
According to the government of Goiás and the International Atomic Energy Agency (IAEA), Goiânia’s cesium-137 accident claimed only four lives, but the Goiás Public Prosecutor’s Office and the Association of Cesium Victims (AVCesio) say that at least 1,400 people were contaminated and that 66 have died as of 2017.
After the Fukushima nuclear disaster in Japan,Time magazine produced a list of 12 of the Worst Nuclear Disasters. Goiânia was one of them. Yukiya Amano, director general of the IAEA,pointed out in a March 25, 2012 Washington Postcolumn, that the Goiânia incident “involved the unintended release of radioactivity, but it remains the best real-world indicator of what could happen on a larger scale if terrorists were to detonate a dirty bomb in a large city or at a major public event.”

Radioactive Pollution At Los Angeles Jewish Camp
Scientists Concerned About Radioactive Pollution At Los Angeles Jewish Camp https://forward.com/fast-forward/403091/scientists-concerned-about-radioactive-pollution-at-los-angeles-jewish/
Four nationally known scientists are recommending new testing at a popular Los Angeles-area Jewish camp to determine if contaminants at a nearby former nuclear testing site have posed health risks to past and current campers, NBC Los Angeles reported.
The scientists independently reached that conclusion after reviewing various reports of past testing at Camp Alonim and the land it sits on, the Brandeis-Bardin campus, owned by the American Jewish University. The camp is located just below Santa Susana Field Laboratory, which for decades hosted rocket and experimental nuclear reactor testing. The laboratory has long been closed but is still awaiting a full cleanup, according to NBC. Both AJU and state toxics regulators say the land is safe.
“If you looked at this historically and said, ‘Could being at the camp have led to radiation exposure’ the answer is yes,” said Dr. Jonathan Samet, an internationally known radiation expert and dean of the Colorado School of Public Health, one of the scientists interviewed.
Among the key findings from the two-year investigation are that the test results cited by the camp and state regulators are either too old or too inconclusive to definitely say whether children are safe from contamination from the Field Lab. The article also claimed a 2016 study paid for by the camp’s owner, to investigate concerns about contamination, is flawed. AJU also says the camp has no history of growing food for children to eat in the potentially toxic soil, a claim challenged by past staff.
The article originally was planned to appear in the Los Angeles Jewish Journal, but according to NBC, the Jewish Journal’s new publisher declined to publish the story.

Amazingly High Radiation in Tokyo Bay — 131,000 Bq per Meter Squared
Abstract http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0193414
A monitoring survey was conducted from August 2011 to July 2016 of the spatiotemporal
distribution in the 400 km2 area of the northern part of Tokyo Bay and in rivers flowing into it of radiocesium released from the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident.
The average inventory in the river mouth (10 km2) was 131 kBq⋅m-2 and 0.73 kBq⋅m-2 in the central bay (330 km2) as the decay corrected value on March 16, 2011. Most of the radiocesium that flowed into Tokyo Bay originated in the northeastern section of the Tokyo metropolitan area, where the highest precipitation zone of 137Cs in soil was almost the same level as that in Fukushima City, then flowed into and was deposited in the Old-Edogawa River estuary, deep in Tokyo Bay.
The highest precipitation of radiocesium measured in the high contaminated zone was 460 kBq⋅m-2. The inventory in sediment off the estuary of Old-Edogawa was 20.1 kBq⋅m-2 in August 2011 immediately after the accident, but it increased to 104 kBq⋅m-2 in July 2016. However, the radiocesium diffused minimally in sediments in the central area of Tokyo Bay in the five years following the FDNPP accident.
The flux of radiocesium off the estuary decreased slightly immediately after the accident and conformed almost exactly to the values predicted based on its radioactive decay. Contrarily, the inventory of radiocesium in the sediment has increased.
It was estimated that of the 8.33 TBq precipitated from the atmosphere in the catchment regions of the rivers Edogawa and Old-Edogawa, 1.31 TBq migrated through rivers and was deposited in the sediments of the Old-Edogawa estuary by July 2016. Currently, 0.25 TBq⋅yr-1 of radiocesium continues to flow into the deep parts of Tokyo Bay.
Faster global warming predicted, with new Antarctic study
Climate Central By Mikayla Mace, Arizona Daily Star 10 June 18
A group of scientists, including one from the University of Arizona, has new findings suggesting Antarctica’s Southern Ocean — long known to play an integral role in climate change — may not be absorbing as much pollution as previously thought.
To reach their contradictory conclusion, the team used state-of-the-art sensors to collect more data on the Southern Ocean than ever before, including during the perilous winter months that previously made the research difficult if not impossible.The old belief was the ocean pulled about 13 percent of the world’s carbon dioxide — a greenhouse gas that contributes to climate change — out of the atmosphere, helping put the brakes on rising global temperatures.
Some oceanographers suspect that less CO2 is being absorbed because the westerlies — the winds that ring the southernmost continent — are tightening like a noose. As these powerful winds get more concentrated, they dig at the water, pushing it out and away.
Water from below rises to take its place, dragging up decaying muck made of carbon from deep in the ocean that can then either be released into the atmosphere in the form of CO2 or slow the rate that CO2 is absorbed by the water. Either way, it’s not good.
The Southern Ocean is far away, but “for Arizona, this is what matters,” said Joellen Russell, the University of Arizona oceanographer and co-author on the paper revealing these findings. “We don’t see the Southern Ocean, and yet it has reached out the icy hand.”
Oceans, rivers, lakes and vegetation can moderate extreme changes in temperature. Southern Arizona has no such buffers, leaving us vulnerable as average global temperatures march upward.
“Everybody asks, ‘Why are you at the UA?’” Russell said about studying the Southern Ocean from the desert at the University of Arizona. She said the research is important to Arizona and the university supports her work.
…….. scientists know less about the Southern Ocean than the rest of the world’s oceans. What they do know is mostly limited to surface CO2 levels in the summer, when it’s safer to take measurements by ships with researchers aboard. Shipboard sensors that directly measure CO2 are the accepted scientific standard in these types of studies.
Understanding CO2 levels within the air, land and sea and how it is exchanged between the three is necessary for making more accurate future climate predictions.
To fill the gap in knowledge, Russell and her team have deployed an array of cylindrical tanks, called floats, that collect data on carbon and more in the Southern Ocean year-round. Russell leads the modeling component of this project called Southern Ocean Carbon and Climate Observations and Modeling, or SOCCOM.
The floats drift 1,000 meters below the surface. Every 10 days, they plunge a thousand meters deeper, then bob up to the surface before returning to their original depth.
For three years, 35 floats equipped with state-of-the-art sensors the size of a coffee cup have been collecting data along the way and beaming it back to the researchers, like Russell in Tucson. Within hours, the data is freely available online.
They measure ocean acidity, or pH, and other metrics to understand the biogeochemistry of the elusive ocean, but not without controversy.
Making a splash
Alison Gray, an oceanographer at the University of Washington, is the lead author on the study. She said there are two reasons the study may contradict what has previously been thought of about the Southern Ocean: The lack of winter-time observations at the ocean by other researchers and the fact that ocean carbon levels might vary throughout the year.
So while SOCCOM is making it possible to get more data than ever before, others question her nontraditional methods. ………http://www.climatecentral.org/news/antarctic-ocean-discovery-warns-of-faster-global-warming-21865
26,000 tons of radioactive waste sits at the bottom of Lake Powell
https://inhabitat.com/26000-tons-of-radioactive-waste-sits-at-the-bottom-of-lake-powell/ Located on the Arizona–Utah border, Lake Powell serves the drinking water needs of 40 million people in the Southwest while welcoming over 3 million recreational visitors every year. However, what lies beneath may give pause to those who depend on the lake. OZY reports that silt on the lake bed covers 26,000 tons of radioactive waste. A remnant from the mid-century uranium boom in the American West, the radioactive stockpile is not thought to be particularly dangerous. Still, even trace amounts can increase the risk of anemia, fractured teeth, cataracts and cancer – dangers which can become more threatening if Lake Powell suffers an extended drought.
High levels of radioactive Caesium in Ukraine region around Chernobyl a threat to children
Ukrainian villages still suffering legacy of Chernobyl more than 30 years on https://www.eurekalert.org/pub_releases/2018-06/uoe-uvs060718.php UNIVERSITY OF EXETER
Milk in parts of Ukraine has radioactivity levels up to five times over the country’s official safe limit, new research shows.
Scientists from the Greenpeace Research Laboratories at the University of Exeter and the Ukrainian Institute of Agricultural Radiology sampled cow’s milk from private farms and homes in the Rivne region, about 200km from the site of the Chernobyl Nuclear Power Plant explosion in 1986. They found levels of radioactive caesium in milk above Ukraine’s safe limit for adults of 100 Becquerel per litre (Bq/L) at six of 14 settlements studied, and above the children’s limit of 40 Bq/L at eight sites.
The highest levels found were about 500 Bq/L – five times over the limit for adults and more than 12 times that for children.
“More than 30 years after the Chernobyl disaster, people are still routinely exposed to radioactive caesium when consuming locally produced staple foods, including milk, in Chernobyl-affected areas of Ukraine,” said Dr Iryna Labunska, of Greenpeace Research Laboratories at the University of Exeter.
“Many people in the area we studied keep cows for milk, and children are the main consumers of that milk.
“Though the level of soil contamination in the studied areas is not extremely high, radioactive caesium continues to accumulate in milk and other foods, such that the residents of these villages are chronically exposed to radioactivity that presents health risks to almost every system in the body – especially among children.”
The researchers say that some simple protective measures could be taken to bring radiation exposure levels below limits at a cost of less than 10 euros per person per year for the 8,300 people living in the six villages with the highest contamination.
Such measures include applying a caesium binder, called Ferrocyn, to cows, mineral fertilisation of potato fields and feeding pigs with uncontaminated fodder.
The cost of this would decrease each year as radiation levels fall – but if no action is taken, the experts warn that milk contamination will continue to exceed the 100?Bq/L adult limit in parts of Ukraine until at least 2040.
“The Ukrainian government has taken some of these measures in the past, but that stopped in 2009,” Dr Labunska said.
“Government and international monitoring needs to take place, along with help for people affected by this radiation.
“This situation should also act as a warning and a reminder of just how long the legacy of nuclear accidents can be.
“Without adequate countermeasures, what may now seem a purely historical event will remain a daily reality for those communities most impacted.”

Grand Canyon – too important, too majestic, to be ruined by uranium mining
Renewed uranium mining is an unconscionable threat to the Grand Canyon Chicago Sun Times, Thomas Frisbie, 05/26/2018, @thomasfrisbie | email
The spectacular and majestic Grand Canyon, eons in the making, needs our help. Some Republican members of Congress want President Donald Trump to overturn a ban on new uranium mining nearby, along with other conservation measures. We need to urge Congress to protect this national jewel.
Some six million people arrive each year to view the vast, multi-hued and intricate canyon, though most don’t venture far from the rim. For them, it’s an inspiring and breath-taking sight. But hardy trekkers who explore remote trails might see something else: signs warning them they are entering an area of the canyon tainted by radioactivity spewed years ago from uranium mines. National Geographic reports uranium leaching from old mines has rendered 15 springs and five wells inside the canyon unsafe to drink. We don’t need more of that.
Uranium pollution is no way to treat an immense and ancient panorama of stunningly varied rock that has been called one of the seven wonders of the natural world. Recently, I had an opportunity to backpack with intrepid family members from the rim to the bottom and camp along Bright Angel Creek, near where it flows into the Colorado River. The ever-changing vista along the rocky trails was magnificent. Unafraid mule deer browsed just a few feet from us. A rare condor flew overhead. Bold rock squirrels waited for a chance to gnaw and rummage through any backpacks absent-mindedly left on the ground.
….. We now have a president who last year ordered federal agencies to review anything that could interfere with domestic energy production. In response, the Forest Service in November recommended reopening land near the Grand Canyon for uranium mining. In March, groups representing the mining industry asked the U.S. Supreme Court to lift the ban on new uranium mining on public land bordering the Grand Canyon National Park.
Uranium mining is extremely risky for the environment. Mining releases radioactive dust into the air and contaminates the land and water with radioactive and toxic substances.
“Uranium mining has left a toxic trail across the West — including at the Grand
Canyon itself,” the environmental group Environment America wrote in its April report update, “Grand Canyon at Risk: Uranium Mining Threatens a National Treasure.”
The waste rock and dirt left behind can remain radioactive for hundreds of thousands of years and also contain toxic chemicals such as arsenic that can contaminate the surrounding environment and make the mines themselves permanently hazardous, the report says.
Steve Blackledge, Environment America’s conservation program director, says, “Some places are too majestic, too important to ruin. At a time of energy abundance and the remarkable growth of clean renewables, messing with the Grand Canyon to turn on a few more light bulbs is beyond absurd.”……https://chicago.suntimes.com/working/renewed-uranium-mining-is-an-unconscionable-threat-to-the-grand-canyon/
The birds and the bees disoriented by electromagnetic radiation: a warning about 5G networks
Electromagnetic radiation from power lines and phone masts poses ‘credible’ threat to wildlife, report finds https://www.telegraph.co.uk/science/2018/05/17/electromagnetic-radiation-power-lines-phone-masts-poses-credible/ Electromagnetic radiation from power lines, wi-fi, phone masts and broadcast transmitters poses a ‘credible’ threat to wildlife, a new report suggests, as environmentalists warned the 5G roll out could cause greater harm.
An analysis of 97 studies by the EU-funded review body EKLIPSE concluded that radiation is a potential risk to insect and bird orientation and plant health.
However the charity Buglife warned that despite good evidence of the harms there was little research ongoing to assess the impact, or apply pollution limits.
Japan’s planned Olympics torch relay route found to have high levels of radiation
the proposed torch route samples had the highest mean radioactivity due to their close proximity to the plant. Based on the measurement, we estimated qualitatively that the radiation exposure of people living near the Azuma Sports Park area was 20.7 times higher than that of people living in Tokyo. The main tourist and proposed torch routes had radiation exposure of 24.6 and 60.6 times higher, respectively, than in Tokyo.
our results showed that the highest radioactivity level was at the proposed torch route, which is located to the northeast of the plant.
Olympic officials should consider using the results of this project to decide whether the radioactivity level at the proposed torch route and the Olympic venues are within acceptable level.
Measuring Radioactivity in Soil and Dust Samples from Japan Fukushima IQP Final Report. An Interactive Qualifying Project Report Submitted to the Faculty of the Worcester Polytechnic Instituteby Thang Pham Steven Franca Son Nguyen
Abstract
A radioactivity map of Cesium-137, a radioactive material emitted from the Fukushima Dai-ichi Nuclear Power Plant, was created by examining 30 soil and dust samples originating from Japan. A Sodium Iodide (NaI) detector measured gamma rays emitted from the samples. Qualitative evaluation of human exposure to radio-cesium in five sets of locations in Japan shows the radioactivity of tested samples. The Fukushima section of one of the Olympic proposed torch route has a 60 times higher activity of Cesium-137 than the activity of the samples from Tokyo.

Executive Summary
Overview
On March 11th, 2011, a magnitude 9.0 earthquake hit the Fukushima Prefecture of Japan (AESJ, 2015, p.19). This resulted in major structural damage to the surrounding area. Following the earthquake, a 13-meter tsunami hit the Fukushima Dai-ichi Nuclear Power Plant and disabled the backup the diesel backup power generator and the cooling water pumps needed to keep the Power Plant running in the event of a disaster. Since power restoration was unsuccessful and there was major structural damage caused to the Units by the tsunami, there were high concentrations of nuclear particles released into the air.
The amount of radioactive materials emitted from the Power Plant raised health and environmental concerns to the people living in the areas around the Fukushima Dai-ichi Nuclear Power Plant. In fact, several studies conducted after the accident determined the activity of radioactive isotopes in the environments. These studies around Fukushima provided excellent understanding of the activity of radioactive isotopes in the environment and the health effects on humans.
With the upcoming XXXII Olympiad in 2020 hosted by Japan, it is necessary to look into the radioactivity of Olympic venues as well as tourist attractions in the host cities. Previous studies pose a major gap because they focused on regions that are closer to the Fukushima Daiichi Nuclear Power Plant, where the highest concentration of radioactive fallout is located. On the other hand, the radioactivity in other locations in Japan is relatively less studied. Since thousands of athletes and millions of visitors are travelling to Japan for the Olympics, there has been widespread concern from the international community about radiation exposure. Therefore, it is important to investigate the extent of radioactive fallout from the Fukushima Dai-ichi incident.
Project goals and Objectives
The goals of the project were to measure the radioactivity of Cesium-137 in soil and dust samples from Japan and to generate a map that illustrates the activity of Cesium-137 in five locations in Japan.Understanding the radioactivity in Japan soil would help in giving an estimation of human exposure to radioactivity in the studied areas. The primary objectives of this project were to:
- Perform soil sample preparation for measurement, including categorizing, drying and sub-sampling
- Measure the activity of Cesium-137 in the samples and analyze the radioactivity at different locations in Japan.
- Generate a map to illustrate the radioactivity level in Japan soil.
- Estimate qualitatively human exposure to radioactivity for people living in the studied areas.
Development of methodology
The employment of various study methods and experiment designs helped complete the objectives. Through literature review and discussion with advisors and lab instructors, we were able to develop main steps and setting for our study.
Primarily, we performed preparation for 87 soil and dust samples collected in Japan and transferred to Worcester Polytechnic Institute (WPI). The samples were classified into five categories based on their original location: Tokyo samples, Azuma Sports Park samples, proposed torch route samples, tourist route samples and non-Olympic samples. All the samples were dried and sub-sampled so that their physical conditions were consistent throughout the testing phase. From the 87 samples that are dried and sub-sampled, we eventually further narrowed to 30 samples for radioactivity measurement.
Previous studies on radioactive nuclides accumulation in soil and dust samples from Japan identified that Cesium-137 had the highest concentration among radionuclides in Japan soil (Saito et al., 2015). Therefore, we set our goal to measure the activity of Cesium-137 in the samples from Japan. A thallium-activated sodium iodine detector, or NaI (TI) detector, measured the concentration of Cesium-137 in the soil samples. The calibrating sources used for Cesium137 measurement were Cesium-137, Sodium-22 and Manganese-54. The experiment reported the radioactivity of the background and the radioactivity of Cesium-137 in the samples above the background. Measurements were made in triplicate to provide counting variability statistics.
At the beginning of the project, samples were selected randomly for measurement. Our focus then shifted, as we looked deeper into the four main areas that will be important to the XXXII Olympiad in 2020. These Olympic areas included Azuma Sports Park, tourist attractions in Tokyo, a proposed torch route, and official designated tourist routes. Time constraint and large amount of samples, limited testing which resulted in results on only a limited part of each sample set.
After finishing measuring, the radioactivity of the soil and dust samples helped generate a map that shows the activity of Cesium-137 in Japan soil. Since there was a large variation in the measured activity between samples at different locations, we decided to analyze the results based on the samples’ original locations.
Our results were cross-referenced with information and results gathered from literature reviews. Understanding the activity of Cesium-137 in Japan soil, we were able to give a qualitative estimation of human exposure.
Results and Analysis
By the end of the project, we were able to measure the activity of Cesium-137 in 30 soil and dust samples. The results showed a great variation in radioactivity between samples from different locations. The activity of Cesium-137 in the 30 samples ranged from 38.6 Bq/kg to 28041.5 Bq/kg with the mean radioactivity of 4903.3 Bq/kg (standard deviation, σ= 6611.0 Bq/kg).
Among the five categories of locations, the Tokyo sample set had the lowest radioactivity mean of 117.6 Bq/kg. The following locations are ordered by increasing mean of radioactivity: Azuma Sports Park samples (2703.9 Bq/kg), main tourist routes samples (3206.0 Bq/kg) and proposed torch route samples (7896.0 Bq/kg). Only one of the non-Olympic samples, which originates from the Entrance to Fukushima Dai-ichi waste mounds, had a radioactivity of 14119.8 Bq/kg. Due to this outlier, this sample set was omitted from the other sets.
The measured results showed that the Tokyo sample set had the lowest radioactivity level, which was understandable based on its significant distance from the Fukushima Nuclear Power Plant. On the contrary, the proposed torch route samples had the highest mean radioactivity due to their close proximity to the plant. Based on the measurement, we estimated qualitatively that the radiation exposure of people living near the Azuma Sports Park area was 20.7 times higher than that of people living in Tokyo. The main tourist and proposed torch routes had radiation exposure of 24.6 and 60.6 times higher, respectively, than in Tokyo.
The results in this study were in agreement with published results qualitatively. Saito et al. reported a much higher deposition of Cesium-137 in the area to the northeast of the Fukushima Nuclear Power Plant and the further away from the plant, the lower the deposition of Cesium-137 (2015). Accordingly, our results showed that the highest radioactivity level was at the proposed torch route, which is located to the northeast of the plant. The further away from the plant for example, in Tokyo and the Azuma Sports Park, the lower the activity of Cesium137. However, because of the differences in sampling techniques and reported unit of radioactivity, there could not be an established direct comparison.
Recommendations
Given the aforementioned results, there is significant evidence through our testing, that there are still high amounts of radiation in areas close to the Fukushima Prefecture. Past and current tests found that high amounts of radiation remain at the origin of the disaster. The results showed a significantly higher amount of radioactive materials in the proposed torch route compared to those in Tokyo.
Given the results from testing, we confidently make the following recommendations:
- Further study on the activity of Cesium-137 on the proposed torch route is necessary to understand how much radioactive materials remain.
- A more detailed study with more soil and dust samples can give a more accurate map of specific areas of interest.
- Olympic officials should consider using the results of this project to decide whether the radioactivity level at the proposed torch route and the Olympic venues are within acceptable level. 4. Qualified health professionals should use this data to make connections about short and long-term effects on health.

UK: the environment will have less protection after Brexit
Times 11th May 2018 , The environment will have less protection after Brexit because the proposed
new green watchdog will lack the power to hold ministers to account,
conservation groups have said.
Michael Gove, the environment secretary, has
unveiled plans for a new independent statutory body to replace the role of
the European Commission in ensuring compliance with rules on reducing air
and water pollution and protecting wildlife in Britain.
An Environmental Principles and Governance Bill will be published in draft form this autumn
and will establish what the government described as a “world-leading body
to hold government to account for environmental outcomes”. However, unlike
the commission, which can take legal action against the government for
failing to observe environmental laws and impose fines, the new body may
only have the authority to issue advisory notices.
A Whitehall source said that Mr Gove wanted the body to have much stronger powers but that this had
been resisted by Philip Hammond, the chancellor, who is concerned that
tough enforcement of environmental rules could harm economic growth.

North Korean nuclear test had energy of 10 Nagasaki bombs and moved mountain, geophysicists say http://www.abc.net.au/news/science/2018-05-11/north-korea-nuclear-test-satellites-seismic-monitoring/9746676 By science reporter Belinda Smith, 11 May 18,
An underground North Korean nuclear test in September last year exploded with 10 times the energy of the atomic bomb that exploded over Nagasaki in 1945.
It also caused the overlying mountain peak to sink by half a metre and shift about 3.5 metres south.
These are conclusions drawn by geophysicists, who used satellite radar and instruments that pick up waves travelling through the earth, to calculate the explosion’s depth and strength.
In the journal Science today, they also report signs that a subterranean tunnel system at the test site collapsed 8.5 minutes after the bomb detonated.
In the past, satellite technology — called synthetic radar aperture imagery — has mapped how the ground stretches and warps after earthquakes.
But this is the first time it has been used to examine a nuclear bomb test site, according to Teng Wang, study co-author and a geophysicist at Singapore’s Nanyang Technological University.
Since the United Nations General Assembly adopted the Comprehensive Nuclear-Test-Ban Treaty in 1996, nine nuclear tests have taken place.
Six of these were by North Korea, five of which were at its Mt Mantap facility in the country’s north.
The bombs were detonated in chambers tunnelled into the mountain itself — a granite peak that extends upwards just over 2,200 metres.
But this means the details of the tests, such as the energy produced by the bombs, have been largely unknown outside North Korea — until now.
Eye in the sky, ear to the ground
Dr Wang and his colleagues suspected they could deduce the strength and precise location of the bomb test on September 3 last year, which triggered a magnitude-6.3 earthquake.
Clandestine nuclear activities are tracked by a global monitoring system of sensors that pick up the faint shivers and shudders generated by distant underground blasts and earthquakes.
But while these instruments are capable of picking up the wave signature of a bomb blast thousands of kilometres away, more information is needed to pinpoint exactly where an explosion has taken place.
So in the weeks after the September North Korean bomb test, Dr Wang and his colleagues received images of the Mt Mantap terrain before and after the test, snapped by the German TerraSAR-X satellite.
To map the bumps and dips on the Earth’s entire surface, TerraSAR-X pings radar towards the ground and measures how long it before the signal is bounced back up again.
“As long as the ground is deformed, we can measure it from space using synthetic radar aperture,” Dr Wang said.
Combined with a bit of nifty mathematical modelling — the first time anyone’s modelled an underground nuclear test with radar data — he and his colleagues got a fix on the exact location of the detonation site.
This is a highlight of the work, said Hrvoje Tkalcic, a geophysicist at the Australian National University, who was not involved in the study.
“What’s always difficult is pinpointing an exact location [of a bomb test],” Professor Tkalcic said.
Dr Wang and his team calculated that the top of the mountain subsided about half a metre after the September test, and parts of it shuffled south.
To manage this deformation, the bomb released the energy equivalent to between 109,000 and 276,000 tonnes of TNT in a chamber 450 metres below Mt Mantap’s peak.
The “Fat Man” bomb that exploded over Nagasaki yielded an energy level equivalent to 20,000 tonnes.
Among the data, they found the seismic shivers of a second, smaller event — an aftershock that appeared 700 metres south of, and 8.5 minutes after, the explosion.
The waves produced by the aftershock weren’t consistent with an explosion; rather, it looked like the ground had imploded.
This, the geophysicists suggest, “likely indicates the collapse of the tunnel system of the test site”.
While Dr Wang and his team used data from seismic monitoring systems in China and the surrounding area, Australia has one of the best in the world, Professor Tkalcic said: the Warramunga monitoring station in the Northern Territory, near Tennant Creek.
It’s almost smack bang in the centre of the continent, in an incredibly quiet part of the world, seismically speaking; far from tectonic plate edges, cities and the shoreline, where waves crashing on the coast create seismic noise.
It uses an array of buried instruments to pick up waves that travel through the ground, acting as a giant antenna to amplify weak signals.
“They’re used in the same way as astronomers use arrays of antennas to look at deep space. It’s just that our antennas are pointed to the centre of the earth,” Professor Tkalcic said.
There is also an infrasound detection system at Warramunga station, which detects waves that travel through the atmosphere produced by bomb blasts.
The data is transmitted by satellite to the Comprehensive Nuclear-Test-Ban Treaty Organisation in Vienna, where it is monitored round the clock.
So how do geophysicists know if seismic waves are caused by bomb blasts and not, say, an earthquake or landslide?
In a subterranean explosion, the ground is pushed outwards and compressed, sending a particular type of wave through the ground, Professor Tkalcic said.
An earthquake’s seismic signature is different. If two plates collide, rub against each other or slip, they send out another type of wave.
“We can tell if the first motion was predominantly a compression or if it was a shear type of motion,” Professor Tkalcic said.
Global warming is melting Antarctic ice from below
Warming oceans melting Antarctic ice shelves could accelerate sea level rise, Guardian, John Abraham, 9 May 18, “……With global warming, both of the poles are warming quite quickly, and this warming is causing ice to melt in both regions. When we think of ice melting, we may think of it melting from above, as the ice is heated from the air, from sunlight, or from infrared energy from the atmosphere. But in truth, a lot of the melting comes from below. For instance, in the Antarctic, the ice shelves extend from the land out over the water. The bottom of the ice shelf is exposed to the ocean. If the ocean warms up, it can melt the underside of the shelf and cause it to thin or break off into the ocean.
Around Antarctica, water at the ocean surface cools down and becomes saltier. These combined effects make the surface waters sink down to the sea floor. But as ice melt increases, fresh water flows into the ocean and interrupts this buoyancy effect. This “freshening” of the water can slow down or shut down the vertical mixing of the ocean. When this happens, the cold waters at the surface cannot sink. The deeper waters retain their heat and melt the ice from below.
The study incorporated measurements of both temperature and salinity (saltiness) at three locations near the Dalton Iceberg Tongue on the Sabrina Coast in East Antarctica. The measurements covered approximately an entire year and gave direct evidence of seasonal variations to the buoyancy of the waters. The researchers showed that a really important component to water-flow patterns were ‘polynyas.’ These are regions of open water that are surrounded by ice, typically by land ice on one side and sea ice on the other side.
When waters from the polynya are cold and salty, the waters sink downwards and form a cold curtain around the ice shelf. However, when the waters are not salty (because fresh water is flowing into the polynya), this protective curtain is disrupted and warm waters can intrude from outside, leading to more ice melt.
Based on this study, we may see increased ice loss in the future – sort of a feedback loop. That concerns us because it will mean more sea level rise (which is already accelerating), and more damage to coastal communities. I asked the lead author, Alesandro Silvano about this work:
We found that freshwater from melting ice shelves is already enough to stop formation of cold and salty waters in some locations around Antarctica. This process causes warming and freshening of Antarctic waters. Ocean warming increases melting of the Antarctic Ice Sheet, causing sea level to rise. Freshening of Antarctic waters weakens the currents that trap heat and carbon dioxide in the ocean, affecting the global climate. In this way local changes in Antarctica can have global implications. Multiple sources of evidence exist now to show that these changes are happening. However, what will happen in Antarctica in the next decades and centuries remains unclear and needs to be understood.
This is just another reason to take scientists seriously and act to slow down climate change before it is too late. https://www.theguardian.com/environment/climate-consensus-97-per-cent/2018/may/09/global-warming-is-melting-antarctic-ice-from-below
The power of environmentalism – Israelis, Palestinians and Jordanians unite in campaign for the environment
EcoPeace Middle East and the power of environmentalism, Independent Australia, Sophia McNamara
Sophia McNamara introduces Gidon Bromberg and EcoPeace Middle East — an organisation brokering peaceful cooperation with environmentalism.
ECOPEACE MIDDLE EAST is a unique regional organisation that brings together Israeli, Palestinian and Jordanian environmentalists.
It is the only regional non-government organisation (NGO) that exists in Israel, Palestine and Jordan. Among its many battles, Ecopeace Middle East recently helped increase the supply of clean water and energy to Gaza. This is particularly critical considering the United Nations has predicted that Gaza will become uninhabitable by 2020.
I interviewed Israeli co-director and co-founder of EcoPeace Middle East Gidon Bromberg and he told me:
“Just a one hour drive from here in Tel Aviv, there is a water and sanitation crisis in Gaza … Two million people have run out of water. And today, about 97% of the groundwater is undrinkable.”
Bromberg came up with the idea to start EcoPeace when he realised the environment was being completely left out of the peace agenda of the early 1990s.
Originally from Elsternwick in Melbourne, Bromberg attended Elwood High School (formerly Elwood College) and graduated with degrees in Law and Economics from Monash University. Since age 11, Bromberg had known he wanted to return to his family’s hometown of Tel Aviv, Israel.
Straight after university, he made “aliyah“ — a term that describes the process of a Jewish person returning to Israel.
Bromberg came across an advert saying that a newly established non-profit called the Israel Union for Environmental Defence wanted their first lawyer. He volunteered there one day a week for four years, while still working four days a week in private practice, taking a pay cut in the process.
He was then offered a scholarship to study his Masters of Law at the American University in Washington DC, where he ended up being right on the doorstep of negotiations for the Oslo Accords and the Israel-Jordan Peace Treaty. Bromberg’s Masters thesis posed the question: will peace be environmentally sustainable? He concluded that peace could, in fact, be truly harmful to the environment and sustainability unless it was put on the political track.
Bromberg had the idea to create a regional environmental organisation that would address this exact issue. He wanted to hold a meeting with Israeli, Egyptian, Palestinian and Jordanian environmentalists to discuss the possibility of this organisation. He spoke with potential investors in Washington DC — they all told him it was a great idea, but he needed to come back to them when he was older.
In 1994, he went back to Israel and, as part of his scholarship, he worked for a year at the Israel Union of Environmental Defence as a full-time lawyer.
Bromberg immediately wrote to all the potential investors in the United States again, this time from Israel. One of them called him and said he had thought about it and that if he could make the meeting happen, he would fund it. As these were the days before the internet, Bromberg had never met a Palestinian, Jordanian or Egyptian environmentalist.
The World Wildlife Fund had a guide on environmentalist organisations in the region — so he contacted all of them. Bromberg had a meeting in East Jerusalem with a Palestinian environmentalist, who responded to the enquiry, and spoke over the phone to an Egyptian and Jordanian. …..
Today, EcoPeace has adapted to a changed political climate, increased water scarcity and urgency required by climate change. They focus heavily on shared natural resources, regional water security and sustainable development.
A particularly successful initiative by EcoPeace is the Good Water Neighbours Program. This is where youth and adult activists, as well as mayors and municipal staff from Israeli, Palestinian and Jordanian communities all work together across the borders to advance shared solutions for the rehabilitation of natural watersheds.
The Jordan River, possibly the holiest river in the world, with large religious significance in Christianity, Judaism and Islam, “has been turned into little more than an open sewer now,” says Bromberg.
Bromberg says the issue is about more than the river itself:
“The largest number of volunteers from Jordan who have joined ISIS are from Jordan Valley communities. There is a link between ecological demise, poverty, underdevelopment… and then radical, dangerous ideologies. Water security, ours and our neighbours, are national security concerns.”
This is the case EcoPeace make when they lobby Israeli, Palestinian and Jordanian governments into committing themselves to cross-border water and sanitation projects………. https://independentaustralia.net/politics/politics-display/ecopeace-middle-east-and-the-power-of-environmentalism,11470
Australia’s nuclear bomb test site – touted as tourist site, but it’s still radioactive
‘Yes, there is still radiation here’, Gulf News 4 May 18 , Australia’s least likely tourist spot: a test site for atom bombs “……..
“Yes, there is still radiation here,” Robin Matthews ( Australia’s only nuclear tour guide) said as he drove a minibus to the sites where the Australian and British governments dropped seven bombs between 1956 and 1963, which dotted the earth with huge craters and poisoned scores of indigenous people and their descendants.
Back then, the government placed hundreds of human guinea pigs — wearing only shorts and long socks — in the front areas of the test zones. The effects of large doses of radiation were devastating…….
Today, just four people live full time in Maralinga village, a veritable ghost town. Amid the old buildings are new lodgings built for tourists, complete with hot water and Wi-Fi.
In the 1950s and ‘60s, at the height of the Cold War, 35,000 military personnel lived here.
The first nuclear test was conducted in September 1956, two months before the Melbourne Olympics.
That blast — as powerful as the bomb that the US dropped on Hiroshima — was the first of seven atom bombs set off here. But it was the so-called minor tests that were the most harrowing. Carried out in secret, the tests examined how toxic substances, including uranium and plutonium 239, would react when burnt or blown up.
….. Around one area tourists can visit are 22 major pits, each at least 15 metres deep and cased in reinforced concrete to prevent dangerous radiation from seeping out.
The site looks like a recently tilled garden bed, stretching out for hundreds of yards, in a near perfect circle. Dotting the red desert earth are shards of twisted metal. Aside from a few feral camels loping nearby, it is still and silent.
But on October 4 1956, a “nuclear landmine” was detonated here, tearing a crater 40 metres wide and 21 metres deep into the earth.
‘This is their land’
The resulting atomic reaction took only a fraction of a second, but its effects on one indigenous family would last decades. Survivors of the blasts, their children and grandchildren suffered from cataracts, blood diseases, arthritic conditions, stomach cancers and birth defects…….https://gulfnews.com/news/asia/australia/yes-there-is-still-radiation-here-1.2216400
