Tri-Valley CAREs and Other West Coast NGO's Monitor Radiation Locally

Monday, March 21, 2011 (updated daily)
Posted by Marylia Kelley

Tri-Valley CAREs and independent scientists and other organizations that own radiation detection equipment along the coast of CA, OR, WA, AK and Canada began taking regular radiation readings as the crisis developed and deepened at the Fukushima Nuclear Power Plant in Japan.

We non-governmental scientists and organizations undertook this project with three aims in mind: as a precautionary measure, as a means of establishing local "background" numbers and as a transparency measure to ensure that information would always be publicly available.

A list serv has been set up at nuclear_fallout@googlegroups.com To view the web site where groups are sending their data Click here. Additionally, here, below, is Tri-Valley CAREs' ongoing monitoring journal. We are updating it daily.
