Klimaatonderhandelingen in impasse | nu.nl/buitenland | Het laatste nieuws het eerst op nu.nl: Ontwikkelingslanden vinden dat de geindustrialiseerde landen de zwaarste lasten moeten dragen, omdat zij historisch gezien verantwoordelijk zijn voor de meeste uitstoot.
Die landen vinden echter dat snelgroeiende economieen als India en China er dan te gemakkelijk mee weg komen. China is momenteel de grootste vervuiler ter wereld. "Het is een complete impasse", zei Arthur Runge-Metzger, de onderhandelaar van de Europese Unie.''

Japan herdenkt grootste catastrofe sinds Tweede Wereldoorlog - De aardbeving in Japan - VK
Op het exacte moment dat Japan vorig jaar werd getroffen door een zware aardbeving, werden de 19.000 slachtoffers zondag met een minuut stilte herdacht. Door de aardbeving ontstond een alles verwoestende tsunami, die kerncentrale Fukushima verwoestte en een kernramp veroorzaakte.

Japanese Physicist Publishes Fukushima Radiation Records
The readings at the Fukushima Medical University close to the damaged nuclear power plant make grim reading
Today, an insight into the conditions in the region surrounding the Fukushima Nuclear Power plant soon after the magnitude 9 earthquake and resultant tsunami which caused the reactors to explode.
Fukushima Medical University sits some 60 kilometres northwest of the power station. In the run up to the accident, a physicist at the university, Tsuneo Konayashi, had been measuring the background levels of gamma radiation, the numbers of secondary particles from cosmic ray impacts and the amount of radon in the atmosphere.
So when the accident struck, Konayashi and his colleagues were in a good position to measure exactly how things changed.
First, the background levels of gamma radiation changed little immediately after the earthquake but then spiked, reaching 9.3 times the usual levels on 16 March, five days after the quake and just hours after a hydrogen explosion occurred at the plant That's a level of 11.9 micro Seiverts per hour.
By August, Konayshi says the levels had dropped to 1.5 times the usual levels .
Indoor levels were significantly lower. The Japanese Self-Defense Force screened people entering the university and anyone with more than 10,000 counts per minute had to be decontaminated at separate decontamination tent before entering the campus.
"The maximum value found was 100,000 cpm," says Konayashi. That's a significant level of contamination but it's not possible to say exactly how high because the number of counts for a given level of radiation depends on the measuring apparatus. Other news reports on the web mention a worker at the plant who was sprayed with highly radioactive water while moving a hose leading to readings of 100,000 cpm.
Konayashi says his data can best be explained by fitting it to a model in which there are two types of radiation with short and long half lives. The best fit is for short-lived isotopes, such as iodine-131, that decay with an average half life of about 3.6 days, and with the longer-lived ones, such as cesium-134 and strontium-90, having a half life of 181 days.
The radon levels were unaffected in most places. However, the levels rose appreciably in some indoor locations because the university had reduced ventilation to prevent radioisotopes from entering the building and this also prevented the radon from escaping.
In some places the levels rose to 250 becquerels per cubic metre, almost double the maximum allowable levels in the US. These places had to be sealed off from normal use.
Curiously, the cosmic ray measurements decreased slightly soon after the accident, a phenomenon that Konayashi puts down to an increase in atmospheric pressure which would have shielded the ground from these particles.
During the first few months, Konayashi says he was distributing his data round the campus on a daily basis, to let people know whether there had been further leaks at the plant.
Konayashi says efforts to monitor radiation are ongoing and look likely to continue for the foreseeable future.
We wish them well.

Explosie op nucleaire site in Zuid-Frankrijk
Een verwerkingsbedrijf voor laagradioactief afval op de nucleaire site van Marcoule, in het zuiden van Frankrijk, is getroffen door een explosie. Daarbij zijn 1 dode en 4 gewonden gevallen. Er zou geen radioactieve straling zijn vrijgekomen.
De explosie was het gevolg van een brand op een opslagplaats voor kernafval. Bij de ontploffing vielen zeker 1 dode en 4 gewonden, waarvan er 1 erg aan toe zou zijn. Er is een veiligheidszone ingesteld rondom het getroffen bedrijf.
In eerste berichten was er sprake van een radioactief lek, maar volgens het Franse nucleaire agentschap is er geen radioactief of chemisch lek ontstaan. Op de site bevinden zich geen kernreactoren.

Fukushima's Reactor Cores Still Too Hot to Open
On March 11, a magnitude-9.0 earthquake struck off the coast of Sendai in Japan, knocking out power at the nearby Fukushima Daiichi nuclear plant. In the hours and days that followed, three of the plant's six reactors melted down, triggering a series of explosions and fires at the site. Six months later, what progress has been made to stabilize the plant, and what is yet to be done? [More]

Japan Tsunami Broke Bergs Off Antarctic Ice Shelf | 80beats
What’s the News: The tsunami that deluged Japan in March was so strong that it broke off several large icebergs in Antarctica, 8,000 miles away, researchers report in a new paper [pdf]. Using satellite images, the researchers saw the tsunami causing new icebergs to split off—or calve—from an ice shelf, the first time such an event has been observed.
How the Heck:
Once the tsunami began, the researchers predicted what course it would likely take through the Pacific.The tsunami swell reached Antarctica about 18 hours later, by then measuring only a foot high. To get a clear view of whether the tsunami would cause any calving, the researchers used images from NASA and European Space Agency satellites and watched the swell hit the Sulzburger Ice Shelf in close to real time.
The scientists saw several large pieces of ice—totaling nearly 50 square miles, or twice the size of Manhattan—calve from the ice shelf. The largest of these icebergs was 7 miles long and 4 miles across.
What’s the Context:
Scientists have long suspected that tsunamis can snap off bits of Antarctic ice, but they’d never before watched it happen. Up until ...donderdag 4 augustus 2011

Officials Use Blue, Peelable Goo to Decontaminate Japan | Discoblog
Just pour and peel! Also slices and dices.
Put away that Swiffer—when you’ve got a real mess to clean up, turn to this blue goo.
Japanese officials looking to clean up radioactive contamination are applying a product called DeconGel to the problem. The usual method is distressingly Stone Age: soap and water applied by human beings. As you can imagine, there are a number of problems with this, like what to do with all that radioactive water, which has a tendency to leak all over the place, and what to do about radiation exposure of said human beings.
DeconGel, 100 buckets of which were donated to the relief effort by its manufacturer, CBI Polymers, looks to be a handy way to bypass all that. A radiation-mitigation expert working with Japanese officials put them on to it: “I’ve been doing this for 20 years,” he says, “and there’s nothing comparable to DeconGel out there that I know of today.” (via CNNMoney)
If you’ve ever used a lint roller, you’re familiar with the basic mechanics of DeconGel. The viscous blue goop is poured onto the contaminated surface, allowed to dry, and then peeled off like masking tape from a ...

Have several hundreds of thousand people died because of the Chernobyl disaster?
The Wikipedia article on this is littered with [citation needed] and a commenter of hacker news linked to while stating:
Chernobyl cost several hundred thousand lives. Let's hope and pray Fukushima will not exact a similar cost.
However I read a recent article in the Guardian about a journalist that was seemingly desperately trying to figure out what research backs up such claims. In the link-bait titled article The unpalatable truth is that the anti-nuclear lobby has misled us all he states:
For the last 25 years anti-nuclear campaigners have been racking up the figures for deaths and diseases caused by the Chernobyl disaster, and parading deformed babies like a medieval circus. They now claim 985,000 people have been killed by Chernobyl, and that it will continue to slaughter people for generations to come. These claims are false.
The UN Scientific Committee on the Effects of Atomic Radiation (Unscear) is the equivalent of the Intergovernmental Panel on Climate Change. Like the IPCC, it calls on the world's leading scientists to assess thousands of papers and produce an overview. Here is what it says about the impacts of Chernobyl.
Of the workers who tried to contain the emergency at Chernobyl, 134 suffered acute radiation syndrome; 28 died soon afterwards. Nineteen others died later, but generally not from diseases associated with radiation. The remaining 87 have suffered other complications, including four cases of solid cancer and two of leukaemia.
In the rest of the population there have been 6,848 cases of thyroid cancer among young children – arising 'almost entirely' from the Soviet Union's failure to prevent people from drinking milk contaminated with iodine 131. Otherwise 'there has been no persuasive evidence of any other health effect in the general population that can be attributed to radiation exposure'. People living in the countries affected today 'need not live in fear of serious health consequences from the Chernobyl accident'.
Is the probably widespread belief that Chernobyl disaster has caused hundreds of thousand, or even tens of thousand deaths true when examining the literature?
