Fukushima Daichi: How did I miss this?!

I've been following the Japan tragedy closely, and somehow I missed big news on the U.S. impact of the disaster. Did I miss it, or is the news media not reporting it?
In the US, physician Janette Sherman MD and epidemiologist Joseph Mangano published an essay shedding light on a 35 per cent spike in infant mortality in northwest cities that occurred after the Fukushima meltdown, and may well be the result of fallout from the stricken nuclear plant.

The eight cities included in the report are San Jose, Berkeley, San Francisco, Sacramento, Santa Cruz, Portland, Seattle, and Boise, and the time frame of the report included the ten weeks immediately following the disaster. [Emphasis mine.]
This disaster is starting to look Biblical in its proportions.

UPDATE 10:42 PM EST: Here is the essay It is merely suggestive, not definitive. No study has been done, merely an overview of infant mortality rates before and after the Fukushima Daichi disaster.

Fukushima now on par with Chernobyl

On the "International Nuclear Event Scale", Japan's Fukushima Daichi plant is now officially on par with Chernobyl. International agencies had been arguing for this classification for weeks, but the Japanese government had been stubbornly classifying the event on par with Three Mile Island instead. Now that radiation is leaking into the Pacific Ocean, it appears Japan's reservoir of denial has run out.

Not again! Another earthquake in Japan.

It's the disaster that will not end. Another 7.1 magnitude earthquake has hit Japan 100 miles north of Tokyo. An even more spooky detail, is the quake hit exactly as the people of Japan were taking a moment of silence to remember the 28,000 people dead and missing from the original earthquake and tsunami.
The latest aftershock caused buildings to sway in the capital Tokyo, shortly after the nation had observed a minute's silence to remember the 13,000 people killed in the March 11 disaster and the 15,000 who officially remain missing.

The US Geological Survey said the 7.1 onshore quake hit at 5:16 pm (0816 GMT) at a depth of just 13 kilometres (eight miles). Its epicentre was 81 kilometres south of Fukushima city, near the troubled nuclear plant.

Japan's meteorological agency warned that a one-metre (three foot) wave could hit Ibaraki prefecture, one of the areas pummelled by last month's massive tsunami, before cancelling the alert less than an hour later...

Workers battling to contain the crisis at the Fukushima-Daiichi nuclear plant were evacuated after the latest quake Monday, which briefly knocked out power to crippled reactors before electricity was restored.

What can the air in Seattle tell us about the Fukushima nuclear reactors?

Science is a wonderful thing. Not only does it give us fun gadgets and fascinating theories, but it also allows us to draw highly-accurate conclusions about events happening far, far away. Since the earthquake in Japan, a team at the University of Washington at Seattle has been testing air filters from university buildings for radioactive particles. Their results have allowed them to gauge exactly where the real threat comes from Fukushima Diachi. Even though, they are approximately 4800 miles apart.
The first comes from the amount of iodine-131 and tellurium-132 which are both short-lived with half lives of 8 and 3 days respectively. That indicates that they must have come from fuel rods that were recently active rather than from spent fuel...

Finally, there are a huge number of possible breakdown products from nuclear fission in a reactor and yet the Seattle team found evidence of only three fission product elements--iodine, cesium and tellurium. "This points to a specifific process of release into the atmosphere," they say.

Cesium Iodide is highly soluble in water. So these guys speculate that what they're seeing is the result of contaminated steam being released into the atmosphere.

16% of USA Radiation Monitors Offline for Japan Nuclear Crisis

So far, the nuclear crisis in Japan has posed little threat to the shores of the United States. While traces of radiation have been detected, carried by the winds, none have neared life-threatening or even health-threatening levels. But the disaster has showed up something important - the American radiation-monitoring system may not be adequate for our own disaster. 16% of all detectors were offline for the disaster.
In California, home to two seaside nuclear plants located close to earthquake fault lines, federal officials said four of the 11 stationary monitors were offline for repairs or maintenance last week. The Environmental Protection Agency did not immediately say why the monitors were inoperable, but did not fix them until several days after low levels of radiation began drifting toward the mainland U.S.

About 20 monitors out of 124 nationwide were out of service earlier this week, including units in Harlingen, Tex. and Buffalo, N.Y. on Friday, according to the EPA.
While the failure rate is scary to say the least - especially in an age where we fear dirty bombs and/or suitcase nukes - this served as a good test of the system. Now, we have a chance to fix the problem, rather than letting the problems languish for lack of attention.

We've entered a time of Heroes

There are days when the disaster in Tokyo is overwhelming. And then there are moments that bring it into sharp relief. Like, for example, this quote regarding the rescue workers trying to bring the Fukushima nuclear reactors back under control.
"They need to stop pulling out people—and step up with getting them back in the reactor to cool it. There is a recognition this is a suicide mission," the official said.
Let's not let up praying for the workers and their families. Even if their heroism successfully saves the reactors, it is likely they will not live to see the first anniversary of the Earthquake.

Why is nuclear hysteria on the rise in Japan...

...even as the risk of meltdown is falling? New Scientist has the scoop and it proves yet again that it's not the problem you expect that gets you - it's the one that you didn't realize was coming. Or the one caused by a complex series of unlikely events.
The pools are housed on the top floors of the reactor buildings. Spent fuel rods are transferred to them as soon as they come out of the reactor itself, and are kept under water to cool them down and trap the radioactive material within them. Once they have cooled down enough, the rods are then transferred to outdoor pools for long-term storage.

It is the pools inside the reactor buildings that are causing the problem. Two of the reactor buildings - 1 and 3 - have lost parts of their roofs, thanks to the hydrogen explosions that have taken place over the last few days. While these explosions apparently did not damage the reactors within, they have left the pools exposed to the outside air.

The "Nuclear Rennaisance" is over

As the Middle East has destabilized and British Petroleum dumped thousands of tons of crude oil into the Gulf of Mexico, nuclear-power advocates were seeing a sudden rise in interest in building new, safer power plants. The idea was that modern Nuclear Power was far safer than the days of 3 Mile Island or Chernobyl, so America could power herself without Mideast Oil and without fear of Meltdown. But news of as many as 6 reactors failing in post-tsunami Japan including one which is probably in the middle of a partial meltdown has likely doomed this nascent movement toward energy independence. After all, what politician or regulator is going to approve a new power plant (even a modern, safer one) with smoking radioactive ruins across the Pacific Ocean?

Update 6:02 am: A good summary of worst-case scenarios and an explanation of why Japan was unprepared for this nuclear crisis.

What are the #1 needs of the Tsunami survivors?

While aftershocks are still likely, we can hope that the immediate effects of the earthquakes and tsunami in Japan are over. What comes next? IO9 has a list of the harsh realities facing the survivors, and what is likely to be the first relief they will need. Ironically, the #1 need after tsunami is WATER.
The first long-term problem facing tsunami survivors and disaster responders is procuring water. A huge amount of salt water has swept over the freshwater delivery system that modern society has installed. Furthermore, septic tanks and sewage systems have often burst open. Chemicals and pesticides can render water undrinkable and unsafe for any kind of contact. The initial deliver of bottled water and an ongoing system of scrupulous water testing is a must for the affected areas.
Please continue to pray for Japan. And consider giving whatever you can to the relief efforts.

8.9 magnitude earthquake + tsunami rock Japan

Amazingly, so far only 32 people are reported dead. But there are sure to be more deaths, injuries, and suffering to come from this horrible disaster. Please consider donating to the Red Cross who will likely be first on the scene to help survivors.
The magnitude 8.9 offshore quake was followed by at least 19 aftershocks, most of them of more than magnitude 6.0. Dozens of cities and villages along a 1,300-mile (2,100-kilometer) stretch of coastline were shaken by violent tremors that reached as far away as Tokyo, hundreds of miles (kilometers) from the epicenter...

Even for a country used to earthquakes, this one was of horrific proportions. It unleashed a 23-foot (7-meter) tsunami that swept boats, cars, buildings and tons of debris miles inland...

The U.S. Geological Survey said the 2:46 p.m. quake was a magnitude 8.9, the biggest earthquake to hit Japan since officials began keeping records in the late 1800s.
A tsunami warning was extended to a number of Pacific, Southeast Asian and Latin American nations, including Japan, Russia, Indonesia, New Zealand and Chile. In the Philippines, authorities said they expect a 3-foot (1-meter) high tsunami.

Iran Loses To Japan For Security Council Seat

I didn't even know they were making a bid for it, but Iran has lost to Japan for the Asian non-permanent U.N. Security Council seat. They needed two-thirds of those voting in order to get a seat, but only got 32 votes. I'm not sure how many votes two-thirds is, but Austria got their seat with 133 votes. Thankfully we won't have Iran trying to dictate where U.N forces go or don't go.
