Links about the situation in Japan

This page is to keep the links about the events in Japan. The links to the "original" websites are going over CoralCDN - hence the ".nyud.net" appended to the domain name. Read more about the CoralCDN at http://www.coralcdn.org/. Chances are that not all of the websites may bear the load they will get - so use the CoralCDN so the sites do not die. I'll update this post as I find more links.

Countermeasures for 2011 Tohoku - Pacific Ocean Earthquake

Some baseline on the radiation:

Smoking: "Based on careful assessments of the concentrations of 210Po in the lung tissues, it was estimated that the "hot spots" received an annual dose of about 160 millisievert (about 16,000 millirem), two of the more common units for expressing doses from ionizing radiation." [Health Physics Society]. Divided by 8760 (24*365), this gives 18.26 microsievert/hour delta atop the background radiation levels. Another source with radiation in cigarettes. So if you are smoking you probably should take a note of this.

Here's another image, a scan from a book, I found it on a blog entry in Japanese about radiation impacts. 1 rad = 10 mSv = 10 mGy, the author writes;


And one more reference about radiation effects. And a diagram for comparing the various sources.

So, after setting up this baseline, you can go and look at the data.

http://www.simon-cozens.org/content/radiation-tokyo-how-read-geiger-counter - has good explanation on how to read the counters and what the numbers relate to. This is where I got the first geiger counter link above.

the Japanese earthquake should have caused Earth to rotate a bit faster, shortening the length of the day by about 1.8 microseconds
