Japan Times: “Alarming estimate of cancer fatalities… 1 million extra deaths”

The second part of that headline:  "Nobody mentions krypton and xenon that poured from Fukushima plant, says Gundersen — 2-3 times greater than Chernobyl"  Japan Times via Enenews:
[...]

Experts waved away fears about radiation, cabinet ministers scoffed at comparisons to Chernobyl, and the word “meltdown” itself was effectively scoured from the media.

Some observers, however, were quick to hit the panic button. One of the best known was U.S. antinuclear campaigner Arnie Gundersen, who predicted that the disaster would lead to 1 million extra deaths from cancer.
[...]
Gundersen, a nuclear engineer, says [the official release amount is] an underestimate. He puts the release of cesium at about half that of Chernobyl, and says little attention has been paid to radioactive gases, Xenon and Krypton, which poured out of the No. 1 plant in quantities “two to three times” greater than the 1986 Ukraine meltdown. He is sticking to his original alarming estimate of cancer fatalities.
[...]
Gundersen bases much of his assessment of Fukushima on what he learned from America’s worst nuclear accident, the 1979 partial meltdown at the Three Mile Island plant in Pennsylvania. As an expert witness during the probe that followed, Gundersen said the official estimate of radioactive releases there was also much too low. “You have to remember, we don’t know how much radiation was released. It’s guys like me who have to calculate it.” His assessment upped the official radiation figure for the accident by five times. “I’m dead sure that’s too low,” he says, adding that he believes the true figure could be 15 times higher than the industry estimate.
[...]
He cites the work of Steve Wing, an epidemiologist who says he has tracked 10,000 extra deaths from lung cancer in the first six to seven years after the accident.

“The same gases (Xenon and Krypton) that caused those cancers leaked out of the containment vessel at the Daiichi (No. 1) plant,” he says. “Nobody is talking about it.” He says the gases quickly disperse and are notoriously hard to measure. Other emissions are more straightforward. Plutonium is heavy and does not widely disperse. Cesium is relatively easy to track.
[...]
Future overheard statement heard just about anywhere in the world:  "Nobody told me Fukushima was this serious!  Why didn't anybody do anything?"    "No;  Lots of experts said Fukushima was serious.  You just didn't listen.  .. And now we're all dead.  The End!"

Do not underestimate the severity of the Fukushima nuclear crisis: interview

Excerpts from The Mainichi:

Before her retirement in 2000 from the University of Bremen in Germany, Inge Schmitz-Feuerhake had been an experimental physicist who some 30 years ago had analyzed data on nuclear bomb survivors and warned of the dangers of low-level and internal exposure to radiation. Since 2004, she has been the chair of the European Committee on Radiation Risk (ECRR), a Belgium-based civic organization founded in 1997 independent of the International Commission on Radiological Protection (ICRP), the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), and various governments. In 2003 and 2010, the ECRR released recommendations on radiation risk assessment methods.

..
Mainichi: Some people claim that the stress from worrying about radiation is a much bigger health hazard than radiation itself, while others express concern over the effect that extreme reactions can have on economic activity. What are your thoughts on that?


Schmitz-Feuerhake: The argument that panic is a bigger health hazard than radiation is one that's used all the time. The same argument was used in Germany after the Chernobyl accident, but it's one that lacks a scientific basis.

Isn't people's health, including that of unborn children, more important than economic activity? Of course, it's not good to panic without any information. We must measure radiation levels in our environment and food, and get a grasp on our individual levels of exposure. Based on that, we must try to learn what the information means.
Mainichi: How would you evaluate the way the Japanese government has handled the crisis?

Schmitz-Feuerhake: I praise the government for designating the area within a 20-kilometer radius from the Fukushima No. 1 nuclear plant as a no-entry zone. That it set annual radiation levels of 20 millisieverts as a standard for evacuation is understandable for a government that was unprepared for a large-scale nuclear disaster. But it's being grossly irresponsible by reactivating nuclear reactors and trying to shift the public's attention towards "recovery."
With the bombs dropped on Hiroshima and Nagasaki and past atmospheric nuclear tests, the total volume of radioactive material released was clear. In the case of the Fukushima crisis, however, we still don't know how much radioactive material has been released. Nuclear fuel that far exceeds the nuclear bombs in both quality and quantity remain in very vulnerable conditions, and it's unclear whether it will be possible to retrieve them safely in the future. While the amount of radioactive material being released may be far less than immediately after the disaster began, the reactors still continue to release these materials. The government needs to recognize the gravity of this situation.

It might help if other governments(Any Other Government) step up and say something..  Anything..  But we all know that won't happen, either.  Nobody has any suggestions, any directives, or any volunteers for cleanup, for that matter. The global non-reaction to this ongoing crisis remains the most stunning aspect of the last 17 months.  It's quiet;  Too quiet.  Deadly quiet, to be exact..

Fukushima’s Melted Reactors 500 Days On

The ongoing nuclear emergency continues to surpass Worst Case Scenarios.  Just what we need:  A relentless, overachieving catastrophe.  Veterans Today.  Excerpts:

Dr. Paolo Scampa, PhD, a well-known physicist in the European Union, has prepared a radioactive inventory of Fukushima Daiichi’s destroyed nuclear power plants 500 days after the meltdown of three disemboweled, mangled reactors.



The violent extinction level event occurred Mar 11, 2011. The deadly meltdown and dispersion of radioactive fuel throughout the world is on-going to this day.


Because of the nature of long-lived and short-lived radioactivity, this summation of the radioactive Fukushima inventory is valid for many years. Dr. Scampa’s inventory is current as of Friday, June 29, 2012.


There are 1,946 radioactive products produced by nuclear weapons and atomic reactors according to the Oak Ridge Nuclear Weapons Lab in America.


Fifty-five are considered to be long-lived; 898 are considered to be short-lived but last more than eight days. These nine hundred fifty-three radioactive isotopes are included in this analysis.


Nine hundred ninety-three (993) radioactive isotopes are considered dangerous and undergo radioactive decay within eight days; they are not included in this analysis.

Scampa's analysis is dry, and yet, terrifying.  Here ya go..

The three melted reactors combined in Fukushima Daichi contained 257 tons of nuclear fuel enriched to 3.7% Uranium 235 and divided into 1,496 assemblies, each about 172 kg.



Reactor No. 3 also housed 32 MOX assemblies, reportedly enriched to 6% or 330 kg of Pu239.


In addition, the storage pools of these reactors have at least 239 tonnes of fuel residing there for who knows how long (1,390 assemblies) and 31 tonnes of fresh fuel (180 assemblies).
..
The day of the earthquake their fuel was consumed according to the article cited at an average of 23.35 GWd/t at a rate of 24.07 kg/t for a total of 6.186 tonnes of fuel fissioned.

..
Overall, 9 tonnes of fuel was subjected to atomic fission or activation transformation occasioning a prodigious explosion of radioactivity and radiotoxicity which over time, is several times the amount needed to kill by internal contamination the whole human race.

..
The most remarkable of the volatile elements (elements of which the boiling point is inferior to 1,500 degrees Centigrade and escape above all the first coriums). 37,921 PBq; 1 billion Ci; 18 billion potential inhaled lethal doses.



The official report of the Japanese government to the IAEA [International Atomic Energy Association] contains a hypothesis that the emanations of nuclear fuel from Fukushima Daiichi are equivalent to the ones observed at Chernobyl.


We can see by comparing the subsets of figures below that the radioactive particle emission through the air from Fukushima is not only 3.7 times higher than Chernobyl; but, more importantly, 28.3 times more radiotoxic with every breath you take.


So we got that goin' for us; which is nice..  I still can't believe no one talks about Fukushima.  The level of global denial is..  Beyond words.
