Radioxenon gas is one of the major byproducts from the fission of uranium. Above normal concentrations of xenon gas in the environment can help determine if nuclear fissioning has occurred from either reactors, or weapon detonations.....The radioxenon isotopes of interest for this experiment are xenon-131m, xenon-133m, xenon-133 and xenon-135.
Xenon gas, a noble element, will not bond to other elements to create molecules, thus it will remain highly mobile and in its’ pure form. This characteristic (mobility) allows for the gas to
escape from normal containment situations, such as underground nuclear detonations, where other fission products would normally become trapped.
During the fission process, a plethora of products are created with a wide range of properties. From the fission products produced, only two are created as noble gases, krypton and xenon. Of these, xenon is more prominently produced during the fission process. Other nuclides such as cesium are decayed from xenon, so may temporarily be suspended as a gaseous product.
we are resellers of DigitalGlobe imagery and can assist with your recent request to them. We very likely do have recent data but I wanted to let you know the price would start at $350 for this imagery.

I am surprised there are no recent up-to-date ones out on the internet from news companies.

For the first Time since the beginning NHK showed the Corium "under" the Cement Table
for a "theoretical Explanation" (7pm. News)
Reactor 2 look so harmless (brumm, brumm)
and now this, and the whole Story for the next 20 Years at minimum
every day a day full of fear for the Humankind
Do we will still sit here in 5-10 years or even longer, and exchange our Information?
Think Year 2035 and we are still in high Alert, every Day, every Night!

Radiation readings of US top soil. Far different than Berkeley's. First the milk samples, now this. The folks at Berkeley are loosing credibility.
UC consistently found only 2.2 to 2.9 Bq/kg while the researcher doing the doctorate found levels in soil of 296 Bq/kg, over 100 times greater.
But then again, UC Berkeley is a school of nuclear engineering. Sink nuclear power and that school would be obsolete.
In general, I don't trust any agency that is govt run or govt funded.
Especially in the US.
The DOE's 2012 fiscal year budget request to the US Congress for nuclear energy programmes was $755m.
Kathleen Sullivan, an anti-nuclear specialist and disarmament education consultant with the United Nations Office of Disarmament Affairs, said it's not surprising that research critical of the nuclear energy and weapons isn't coming out of universities and departments that participate in nuclear research and development.
"It (the influence) of the nuclear lobby could vary from institution to institution," said Sullivan.
"If you look at the history of nuclear weapons manufacturing in the United States, you can see that a lot of research was influenced perverted, construed in a certain direction."
Sullivan points to the DOE-managed Lawrence Berkeley National Laboratory at the University of California in Berkley (where some of the research for the first atomic bomb was done) as [color=limegreen]an example of how intertwined academia and government-funded nuclear science are.
.....The discovery of an atomic reaction that can produce a nuclear explosion comes amid rising concerns about possible contamination after another radioactive hot spot was discovered in Tokyo on Oct. 29. It’s possible there are similar reactions occurring in the No. 1 and No. 3 reactors, the other cores damaged at the station, Matsumoto said.

It sounds like a story ripped from the parody-filled pages of The Onion, but some Japanese lawmakers really do want to build a "backup city" that would take over the functions of Tokyo, including tourism, in the event of a catastrophe. The idea was floated last month at a Tokyo luncheon, with a follow-up in The Telegraph last week. "The idea of being able to have a backup, a spare battery for the functions of the nation ... isn't this really a good idea?" Hajime Ishii, a parliamentarian representing the ruling Democratic Party of Japan, was quoted as saying. -------------------------------------------------------------------------------- Live Poll Is building a backup capital city a good idea? Yes: For Japan, it makes sense. No: This will never get off the ground. I'm torn (share your comments below). . VoteView Results Support for creating an urban Plan B has grown in the wake of the earthquake and tsunami that devastated Japan in March and led to the Fukushima nuclear crisis. "Preparations are already under way at various levels at various levels to find ways of mitigating possible far-reaching consequences of a much-expected earthquake striking Tokyo," the Foreign Correspondents Club of Japan said.
“There was a “100-Fold Increase in Krypton-85 from November 1,” reports EX-SKF.
However, according to a study published in the Journal of Environmental Radioactivity, “Krypton-85 is the best indicator for clandestine plutonium separations” when conducting wide-area atmospheric monitoring.
At around 7:20 pm on the same day, Japan Atomic Energy Agency evaluated that the TEPCO's analysis result of the short-half-life radionuclide such as Xe-133 and Xe-135 detection was valid. We consider that they were generated by the spontaneous fission.
WASHINGTON — The 2,000-mile-long debris field from the March tsunami in Japan is expected to reach beaches in Hawaii next winter and hit Washington state's coast starting in late 2013.
Yet U.S. authorities can't say yet how much of the massive flotsam will sink as it swirls through the North Pacific gyre and how much will wash ashore. They are pretty certain it won't be radioactive — requiring special disposal — but don't know for sure.
Sen. Maria Cantwell says the United States better prepare for whatever crosses the Pacific Ocean.
The Japanese power company Tepco has played down the detection of xenon at the melted-down Fukushima No 2 reactor, saying there is no evidence the nuclear reaction has started again.
Tepco said on Wednesday it had detected xenon, a fission byproduct, and as a precaution had poured into the reactor a mixture of water and boric acid, which helps prevent nuclear reactions. "Analysis suggests that it was not a criticality," said Ai Tanaka, a spokeswoman for Tepco.
The government and Tokyo Electric Power Co., the operator of the tsunami-hit Fukushima No. 1 Nuclear Power Plant, should step up their monitoring of the plant's reactors to check whether nuclear fission is occurring and provide good explanations of the situation in the reactors to the public.
Residents wary about radiation in the wake of the ongoing the crisis at the Fukushima No. 1 Nuclear Power Plant have been uncovering abandoned radioactive substances, with repeated discoveries of radium-266 in Tokyo's Setagaya Ward. Radioactive materials were used widely in the past, including in medical products and luminous paints.
After World War II, a law requiring people to obtain the government's permission when using such materials was put into effect, but the law was not always strictly abided by. Now, with many residents armed with dosimeters in the wake of the Fukushima crisis, it is possible that more radioactive materials may be uncovered.
