UC Berkeley reports their first non-detection of isotopes in SF Bay Area milk since early April. http://www.nuc.berkeley.edu/node/2174

I did read the article and it appears that this operation has been in the planning and preparation stage for several years. I'm just surprised that they didn't modify the mission based on the events in Japan.

Here we are, 5 months post event and they are just starting to survey the Puget Sound for contamination. Would the data have been too scary if they tried this back in March? http://www.doh.wa.gov/Publicat/2011_news/11-105.htm

Call it opinion or critical analysis. Azby's post convinced me that the book is fundamentally flawed.

I had read that the New York Academy of Sciences was distancing itself from Yablokov's book because it was not peer reviewed. I think there's no better evidence of this than the fact that the book is out of stock and will not be reprinted by the Academy. It's a very unusual decision for a...

Woods Hole has a research ship (RV Ka`imikai-o-Kanaloa) off the coast of Fukushima surveying the marine environment for contamination. They are blogging about their mission here: https://www.whoi.edu/page.do?pid=68736 They aren't publishing results yet, presumably additional analysis will...

I'd conclude that the earthquake and tsunami didn't break the connection to the stacks. Venting was observed on the 12th and 13th. Post #7684. The highly kinetic environment caused by the explosions broke the stack ventilation. I have to add AFAIK and FWIW...

Most of them, not all...

Just picked this up on the Twitter... Purportedly new images of tsunami flooding from TEPCO http://www.tepco.co.jp/tepconews/pressroom/110311/index-j.html TEPCO slideshow: http://cid-0b14c7ab35e39ebd.photos.live.com/play.aspx/%5ENFNPP1%20Tsunami%20Flooding Forgive me if these have already...

You'll see stack venting here: http://www.youtube.com/watch?v=JAYGclBAym8&feature=related 3.12.11 15:00h @0:24 3.13.11 13:00h @0:30 3.13.11 14:00h @0:31 The video runs until April 6th, but no venting from the stacks seen after 3.13.11

The NRC is winding things down in Japan... "The United States Nuclear Regulatory Commission said on Monday that its 24-hour operations center had stopped monitoring the nuclear reactors at the Fukushima Daiichi plant because the situation there had improved. “The conditions at the Japanese...

Thanks again... I have some reading to do after Saturday chores!

"Limiting Values of Radionuclide Intake and Air Concentration and Dose Conversion Factors for Ingestion, Inhalation and Submersion" is interesting in itself but doesn't answer the question of which isotopes are associated with each energy band on the RADNET graph...

Thanks NUCENG. Unfortunately the EPA link is broken.

The EPA's RADNET site recently spiffed up their user interface, but they provide no guidance on interpreting the gamma graph's energy ranges. If anyone on the forum can associate isotopes with energy ranges that would shed some light. http://www.epa.gov/radiation/rert/radnet-data-map.html For...
