No, some seals are sick and biologists are trying to determine why. One possibility is Fukushima radioactivity, but the testing isn't complete. But don't let those facts impede fear mongering!
Here is the link used by the fear monger which says that test results will take several weeks.

Why The LNT Model Will Be With Us For Many New Years
Sorry, LNT-deniers.
The LNT model of radiation carcinogenesis isn't likely to change anytime soon. It is the best model of radiation risk of cancer versus dose. LNT doesn't "assume" the risk from low doses is absolutely linearly extrapolated from higher doses, as many LNT deniers like to frame the model. It is based on historical evidence, and it could also be called Linear-Quadratic (curved line instead of straight). But just like one ignores the curvature of the Earth when measuring a room for carpet, we can ignore the L-Q curvature in the low dose domain.

I wish I knew how to read Japanese so I could read the links presented in this article.
But based on what is written in English, ties between the yakuza and TEPCO seem fairly nonexistent.

NORM Wastes
Environmental groups are using exposure to naturally occurring radioactive materials (NORM) as a political ploy to stop drilling for fossil fuels. The risks are trivial, especially concerning the landfilled material. I had a post on the topic earlier.

Global Warming Global Disappointment

NIMBY
This article describes the renewed effort by the U.S. gov't to find a location for high level waste. Yucca Mountain, in Nevada, was originally planned as the site, but due to politics has been cancelled. It's hard to imagine any place else taking it without a similar political battle. The only likely exception is the operating WIPP plant in New Mexico which disposes of transuranic wastes from nuclear weapons production.
NIMBY is the acronym for "not in my backyard".

Lack Of Gov't Trust Regarding Fukushima
Here's an LA Times article describing the lack of trust of the Japanese government following Fukushima.
This can lead to greater misinformation as the public hears from quacks, as in one of the lasts paragraphs of the article:
"Another guest was a cancer researcher who emphasized that no matter what assurances the government has made about public safety, children were showing up with "new clinical symptoms of low-dose radiation exposure."
There are no clinical symptoms of low dose radiation exposure other than those associated with cancer. And it's too early for cancer to be symptomatic.

Hanford Whistleblower On Rachel Maddow Show
The clip is here.
Whistleblowing is a tricky thing. On the one hand we all want people to be free to whistleblow. But then, there are some who abuse whistleblowing as a way to intimidate their employer.
I don't know where this particular whistleblower is on the spectrum.
This link contains videos from the Hanford site. If you click on the "Mobile Arm Retrieval System" video you can see inside one of Hanford's high level waste tanks. The tank contents typically have a consistency of dried peanut butter and the MARS tool is used to remotely water blast the contents and vacuum them up.

Indian Point or Oyster Creek: The Next Fukushima?
Here's a pretty good op-ed about New York's Indian Point plant.
The author makes his case without exaggerated fear mongering.
Here's another op-ed concerning New Jersey's Oyster Creek plant.
It's not so good. It supports an anti-nuclear activist who claims he has evidence that the plant didn't follow an NRC order. He even went to the NRC and made a presentation. The NRC and the plant have both said he has it wrong. So if the author's point is that, "Its incumbent upon the NRC not only to determine whether there was full compliance with the order but, more importantly, to assess whether the fire safety protections in place today are sufficient to ward off a Fukushima scenario in Ocean County or anywhere else in the U.S."
It looks like they've already done so.

Spiderman??????
That's the thought that entered my mind when I read this article about web-like growth on spent fuel assemblies..
(Recall that the original Spiderman got his superpowers after he was bitten by a radioactive spider. In the more recent Hollywood version, the spider was "genetically enhanced")
On the serious side, if the growth is biological it may enhance our understanding of extremophiles.

Should Brachytherapy Be Used To Treat Breast Cancer?
In traditional radiotherapy an external beam of radiation is used to irradiate the entire breast.
In brachytherapy, a radioactive source is implanted into the breast yielding partial irradiation.
The latter approach is gaining in popularity, but there are pro's and con's.

Enchanced Radiation Therapy Efficacy Seen
Radiation therapy (and drugs known as radiomimetics) damages the DNA of cancer cells (normal cells too, that why targeting is important in radiation therapy).
DNA has repair mechanisms to sometimes fix the damage.
So, if one can damage the repair mechanisms of the cancerous DNA, one can improve the efficacy of the radiation therapy.
And that's what some scientists have done, using folate as a "Trojan horse" to deliver an antibody into the cell nucleus. The antibody impairs DNA damage repair.

Radiation Safety vs Driving Safety
There is a Commentary in the latest issue of the Health Physics Journal about foregoing the Linear No Threshold (LNT) dose model for cancer risk assessment. The authors agree it is sound to use LNT for radiation protection regulation purposes, however.
So the authors basically are LNT-deniers and employ many of the denialist arguments I've blogged about before.

Is "Cold Shutdown" The Right Term To Describe Fukushima?
Traditionally, "cold shutdown" has meant that there is an intact reactor, the control rods have been inserted to stop fission, and the temperature associated with decay heat is below the boiling point of water.
The Japanese government is saying that the Fukushima reactors will be in "cold shutdown" soon.
Is that appropriate?
The latest long term estimates for Fukushima cleanup is 40 years. This article has an embedded video with some good, but brief, footage of the carnage.

Natural Nuclear Reactors & Life
Here is an interesting article about a possible connection between naturally occurring nuclear reactors and life. A reactor might improve genetic diversity (among survivors) locally, giving life more options for long term success.
Fukushima Spill
It looks like 45 tons of radioactive water spilled inside some sort of water purification facility at Fukushima. Perhaps 300 liters escaped the building. The article is nice in that it actually provides some radiation data, but it's not clear at what height the readings were actually taken. Even if taken close to ground level, that's some pretty contaminated water!
This article includes an embedded video and states that the estimated radioactivity levels were 130,000 Bq/cm3 of strontium (I assume Sr-90).
This article states that 220 tons of water may have escaped the building, big difference from the first article.

Recently with Helen Caldicott.
She claims over a million people died from Chernobyl, which is baseless (actually it's based on the discredited NYAS book). The same book is responsible for claims about deformed children.
She says there's no "pill" you can take to rid the body of radioactive elements. That's not true.

U.S. Coast Guard Awaits Radiation Claims From LORAN Workers
LOnge RAnge Navigation is the source of the LORAN acronym. It was a terrestial radio-based navigation system used by the Coast Guard prior to using more modern GPS systems.
These systems used vacuum tubes. In a vacuum tube, electrons flow from a cathode to the anode within a sealed, airless tube. The electrons emit X-rays as a result of a phenomenon called bremsstrahlung ("breaking radiation"). This usually isn't a safety problem until the voltage exceeds about 15 keV, because until then, the tube itself provides sufficient shielding of the X-rays.
As the voltage increases, additional shielding is required in order to minimize the X-ray dose (since X-ray energy is proportional to the voltage which is causing electron acceleration).
It looks like the Coast Guard didn't inform the LORAN workers of the X-ray risk, and some workers may have been overexposed. Though it's hard to tell from the article which doesn't give any dose estimates.

Radioactive Placards Make Folks Nervous
Radioactive placards are a paradox. They are intended to warn first responders to a potential accident about the hazards associated with the cargo. That's why they're big! So they can be seen from a distance.
But, they also serve as advertising for potential terrorists.
Or, they just scare people!
