Bebt die Erde verstärkt? Erdbeben 8,8 in Japan

Kürzlich spinnte die jap. Regierung und einige Freunde der Kernkraft, dass lediglich Fische unmittelbar in der Nähe der Reaktoren belastet sein könnten.
......
Herr Edano wird wohl demnächst auch Fisch öffentlich verspeisen.
Er wird das sicherlich tun, auch wenn er Fische gar nicht mag!

Studie: http://english.kyodonews.jp/news/2011/04/85516.html
Professors and researchers from across Japan will jointly launch a large-scale study on the environmental and health effects of radioactive materials spread by the crisis-hit Fukushima Daiichi nuclear power plant, people familiar with the matter said Thursday.
More than 100 professors and other scholars will take part in collecting data on the impact of Japan's worst-ever nuclear crisis while establishing a team of academics to check the radiation exposure of residents in areas affected by the leak of radioactive substances.
Starting in May, part of the group, working with the Fukushima prefectural government that has already began its own survey, will collect soil samples at 1,500 locations in areas stretching 100 kilometers along the coastal area centering on the crippled power plant as well as 60 km inland.
With regard to seawater contamination, they will look into the spread of radioactive materials off Fukuoka Prefecture, and their concentration in the food chain and impact on organisms.
They will consider establishing a website to disclose their findings.
The radiation checks will likely cover around 200,000 people living near the Fukushima plant, including around 30,000 who are 14 years old or younger and at high risk of cancer resulting from radioactive iodine accumulation in the thyroid gland.
The main participants in the study will include professors from the University of Tokyo and Osaka University.

A 102-year-old Japanese man killed himself because he did not want to leave his home in the extended radiation zone.
The centenarian lived in the village of Iitate, which until earlier this week was declared safe from radiation leaking from the crippled nuclear plant at Fukushima.
Government officials earlier insisted that anyone living within a 19-mile radius of the plant must move and either stay with relatives or take shelter in an evacuation centre outside the zone.
The elderly man was happy to learn that no one in his village, 25 miles from the plant, would have to move.
But then the government widened the exclusion zone to include Iitate - and he was devastated.
'I'm not leaving,' he told his family. 'I'd rather die than leave my home.'
The old man's name and details of his self-inflicted death have not been revealed.
Municipal officials said the man was upset as he discussed evacuation plans with his family and told them that he saw little point in leaving his home at this stage of his long life.
Under the new orders, the government insisted that residents should move out because of concerns over the effect of long-term exposure to radiation from the leaking nuclear plant.
The health of people living near the plant when it began spilling radiation into the atmosphere will have to be monitored for at least 20 years, medical officials said.

The No. 1 reactor of the Onagawa nuclear power plant in Miyagi Prefecture on April 7 sustained a jolt greater than what it was designed to withstand during a strong aftershock from the powerful March 11 earthquake, according to nuclear safety officials.
The finding raises further doubts about the viability of the assumed quake resistance at the Tohoku Electric Power Co. complex, even though it had been shut down safely after the deadly quake last month.
The Nuclear and Industrial Safety Agency has instructed the regional utility serving northeastern Japan to analyze the impact of such a jolt on key facilities at the three-reactor plant, the officials said.
During the aftershock, the biggest after March 11, measuring upper 6 in Miyagi on the Japanese seismic scale of 7, a seismometer at the building housing the No. 1 reactor registered a quake acceleration of 476.3 gal vertically, against the 451 gal assumed for the facility.

Jetzt versteh ich die Aufregung nicht. Dadd dingens hat doch überlebt - und mehr als vorgesehen. Warum die Aufregung.
Mal was zu Auslegung (nicht AKW - generell). ich nehme mal einen Behälter unter Innendruck (kann in der chemischen Industrie sein oder ein Dampfkessel wie auf einer Lok) oder das Rad an einem Eisenbahnwagen oder...
Wenn das Teil Nominal auf 100 (in irgendwelchen Einheiten der Last) ausgelegt ist, dann
- wird in 4% der Fälle das Dingens trotzdem knapp unter 100 versagen
- wird in 50% aller Fálle das sogar bei 127 noch nicht zerbrochen sein ...
Woher das kommt? (a) iss ne Sache von Stochsitik und Erwartungswerten und Mittelwerten - und dass man dem (b) je nach Betrieb und Belastungsart mit "Sicherheitsfaktoren" (~beiwerten) in einer determinsitischen Berechnung vorbeugt ...
Deshalb gibt es in Japan Labors, in denen man dynamische Belastungen experimentell testet unter Bedingunegn, die 10 (und sogar bis 11) auf der Richterskala entsprechen - Faktoren mehr als man jemals in Erdbebeben gemessen hat ...
Daher: Wenn ein Teil für 100 ausgelegt war und es bricht bei 105 - dann stimmt was an der Berchnung nicht [zB bei einem Erdbeben zu geringe dynamische Faktoren eingebaut] oder man hat eine schlechtes Teil Material erwischt oder die Messung der 105 ist nicht koscher oder ...

A 2004 review suggests that in the year following a technological disaster – such as a plane crash – between 25 and 75 per cent of survivors develop post-traumatic stress disorder (PTSD) – the symptoms of which may include flashbacks to the trauma, as witnessed in Colombia by Lopes-Cardozo. Following a natural disaster, PTSD seems somewhat less prevalent; but that may be because it is often easier to identify the direct victims of a technological disaster than, for example, the victims of an earthquake that affects a large area (Epidemiologic Reviews, DOI: 10.1093/epirev/mxi003</a>).
The crisis in Japan is both natural and technological, which suggests that some PTSD can be expected. The problem will probably be compounded by "radiation anxiety [reuters.com]" – the stress caused by the dread of radioactive contamination. Some researchers have suggested that, for most people, the widespread fear of radiation is more harmful than the radiation itself.
The workers who have risked their lives at the damaged Fukushima Daiichi nuclear plant may be particularly at risk. A study published in 2008 compared the mental health of 295 men who helped clean up the Chernobyl plant in Ukraine after the 1986 disaster and 397 people who lived in the same areas as the clean-up workers but did not work on-site: it found that the former group suffered higher levels of depression and anxiety, and contemplated suicide more frequently (Psychological Medicine, DOI: 10.1017/s0033291707002371</a>).

Eine schwierige Frage, wie aus diesem neuen Gundersen-Interview hervorgeht.
Gundersen nennt eine erste Zahl: 200.000 über die nächsten 50 Jahre.
Das Problem: In den nächsten 50 Jahren werden sehr viele der heute lebenden Menschen sterben, häufig an Krebs.
Die zusätzlichen 200.000 werden vor diesem Hintergrund nur schwer sichtbar werden.

Was für ein unfassbarer Schwachsinn. Es sollte jedem mit einem Funken gesunden Menschenverstand klar sein, dass diese Zahl absurd ist. Ihr könnt euch die Finger in die Ohren stecken und "Lalalalala" schreien so viel ihr wollt. Weniger AKWs bedeutet mehr Kohle bedeutet um Größenordnungen mehr Tote.
Wie wär's mal die Meinung von echten Onkologen oder Strahlenschutzexperten zu posten und nicht die von Schriftstellern, String-Theoretikern, Verschwörungstheoretikern, Anwälten oder ähnlichen?

Noch besser: nichts posten und Strahlenschutzvorlesung besuchen. Danke.

LOL. Ich stelle eine absurde Zahl in den Raum aber ihr werdet sie nie messen können. Was ist den das für einer?

Ich habe dazu mal einen neuen thread aufgemacht, weil nach Posting Nummer 599 findet man in dem thras nicht mal mehr seine eigenen Beitráge ...
es geht hier mit
- Erdbeben und seinen Folgen
- Berichte über den Stand Fukushima
- Beiträge über "gefühlte"" Auswirkungen bis zu ernsthaften Analysen
- allgemeinen lebensweisheiten
zu ziemlich durcheindander ...
How does this work?
This is how you contribute to the prediction - See the Infocenter
