Other useful information:

  • RDTN.org - A local Portland, OR guy, Marcelino Alvarez, created this app in 72 hours to display the reliable (radiation levels) data readings as they become available. Although they are careful to evaluate new data sources, they welcome new reliable data from those on the ground in this crisis. With conflicting reports of radiation levels in affected areas, they wanted to build a way to report and see data in an unbiased format.

Thanks for noticing it, Rich. I started hearing about the mapping and Google applications that were springing up around this, and then I put down the international sources that I was watching, and then I fell in. I'm glad it's helpful.
