Radiation Network – Real-time map of rad detection centers across the US and some locations over the globe. At this time (%-20-2012) it appears to be the most comprehensive site on the net. RadNet sells detectors and software for analysis.
http://potrblog.com/ – Pi***** On The Roses site. Very interesting monitoring and explanation of radioactive transient and fallout readings. Active blogging on anomalous readings. This is a great companion to the Radiation Network above.
Black Cat Systems – This site has a limited graphical display of the US, but also includes links to graphs generated in Japan. They claim a background reading level between 5 and 28 for the US, for cesium and cobalt isotopes Cs137/Co60. Black Cat sells detectors and software for analysis.
Alexander Higgins – Mr. Higgins has created an app on his blog that tracks real-time data along the West Coast, CA, OR WA and AK. The 2011 date shouldn’t fool you, as the graphs starting shortly down the page are dated with the current date. There is a lot of explanatory information along with related news items. This site also has a pointer to an “updated” site, from the EPA.
Seattle Washington – Their own integrated radiation sensor map. May be useful for pacific plume detection. Near real-time data.
Japan Geiger Map – Real time Japanese radiation information on a map. Detailed levels.
