Potrblog, Chernobyl, and Fukushima

Potrblog: No Jetstream, And Still 20X Background Radiation In 8:15 pm Storm

MAJIA HERE: Meanwhile, blogger Ex-SKF is reporting that a french study claims radiation fallout from Fukushima was a fraction of the fallout from Chernobyl (e.g.,

I've posted previously competing estimates and I would take this new study with a grain of radium given the current efforts to frame media understanding of Fukushima radiation.

Here is the study cited by Ex-SKF (who doesn't reveal whether he believes it or not)

November 14, 2011 Xenon Gas and Lethal Doses by Inhalation (this site is in French so I used Google translate): The AIPR or International Association for the Protection Against Ionizing Radiation posted this on Nov 4 (please note it is translated from the French) "The program "semi formalized" in Fukushima of 1.67 E19 Bq 133 Xe gas have meant the spread of 2.411 kg. This emission is equivalent in terms of internal radiation lung 400.8 million in potentially lethal doses by inhalation. As shown, 2.4 kg of material having the power to kill only transient 400 million people, the Xenon 133 is classified as very low radiotoxic. It's not beautiful science! "The Xe 133 has a half-life of 5.244 days. It decreases in beta mode with a decay constant of 1.52985 s-1 E-6. (Ln (2) / T1 / 2 ie 0.693147 / 5.244 * 24 * 60 * 60 = 1.52985 E-6. ) The specific activity of E15 6.9271 Bq / g E05 Ci/gr.- -1.872 (6.0221415 E 23 / ​​133 * 1.5299 = 6.9271 E-06 E15 Bq / gr.) The inhalation dose factor is of 1.20 E-10 Sv / Bq.


[Japan Times] “A former special adviser to Naoto Kan, who was prime minister when the crisis started, warned that the situation is far from resolved and said Fukushima has exposed a raft of serious nuclear problems that Japan will have to confront for years….”

Helen Caldicott Interview with Arnie Gunderson: If You Love This Planet Radio May 8, 2012
EXCERPT: I would say there are billions, actually trillions, of becquerels per day being released airborne, mainly from Units 2 and 3.

Actually on cold nights you can still the steam coming off those reactors, its not just steam its radioactive steam.

Something on the order of trillions of becquerels per day… trillions of disintegrations per second per day are being released even now.

Dr. Helen Caldicott: So what you’re really saying Arnie Gundersen is that the ocean will continue to be contaminated, kind of for the rest of time. Because there’s no foreseeable way to prevent water leaking out of containment vessels continuously into the ocean… We’re talking about continual contamination of the Pacific Ocean.

Arnie Gundersen: You’re right.

  1. I thought the French claimed that no Chernobyl fallout fell on France and that it miraculously stopped at the French border.
