Japan's TEPCO Suspends Cleanup at Fukushima Plant
Cesium spike. Intermittent recriticality and more hot particles? Fuk
Has anyone seen recent radiation release estimates? News on this has really been slowing down.
1. I found a citizen's created map of fallout and radiation levels.
The fallout from the reactors is over a fairly large zone and appears to impact much more than the 30 km radius from the reactors.
"The prefectural government found on Tuesday radioactive cesium exceeding the limit of 300 becquerels per kilogram in grass collected from pastures in four areas, including Tono and Otsuchi. The areas are located about 150 to 200 kilometers north of the Fukushima nuclear power plant."
3. Cesium 137 discussion at Wiki: http://en.wikipedia.org/wiki/Caesium-137
4. An interesting graphical representation of relative radiation doses.
The only site on the West Coast of the USA that appears to be regularly monitoring and reporting data from nuclear isotope monitoring of our food chain.
Congratulations to the students and professors at UC Berkeley for protecting citizen's interests ahead of others.
