    Hold on a minute. Krypton?

    This could be good news.

    Superman should be arriving on the scene any time now.

    I am sure he will save us all…..

    No worries. Only 11 years to get back to April values. (fingers, toes, errrm…)
    - 2033.

    Strange. What the heck is going on in there? Any news re. temp / hydrogen?

    "Krypton-85 is produced in small quantities by the interaction of cosmic rays with stable krypton-84 (which is present in concentrations of about 1 cm3 per cubic meter). However, since the mid-1940s, much larger quantities have been artificially produced as a product of nuclear fission. When uranium-235, or another fissile nucleus fissions, it usually splits into two large fragments (fission products) with mass numbers around 90-140, and two or three neutrons. About three atoms of krypton-85 are produced for every 1000 fissions (i.e. it has a fission yield of 0.3%)"

      In other words, this is indicative of either:

      1) Melting of used nuclear fuel. (Where existing Krypton-85 moves from a 'trapped' condition to an 'untrapped' condition.)

      2) Ongoing nuclear fission. (Generating new Krypton-85 at a yield of 0.3%; the other 99.7% is producing different nuclides.)

      Or both. All bad, but not unexpected.

        Forget about Krypton 85. There are other Krypton nuclides that are neutron rich and decay with a beta particle, thus gaining one proton and moving up 1 spot on the pt. These have such a short HL that it's impossible to even know it happened.

      Huh? 3 atoms of Krypton from 1000 fissions? Fissions of what? U235? Defies logic.

    "RADIOACTIVITY HAZARDS: WARNING! Krypton-85 is a radioactive isotope. Though Krypton-85 occurs naturally and a small amount of this isotope is normally present in the atmosphere, exposure to significant quantities may be harmful.

    "Krypton-85 generates beta particles and gamma rays and poses an external radiation hazard. Upon inhalation of Krypton-85
    gas, this isotope can be incorporated into the body’s cells and emit radiation energy to surrounding tissues. Exposure to this
    product should be kept to levels as low as reasonably achievable."

    "ROUTES OF ENTRY, SYMPTOMS OF ACUTE EXPOSURE: WARNING—If rescue personnel need to enter an area in which a release of Krypton-85 has occurred, they should be equipped with Self-Contained Breathing Apparatus (SCBA) and appropriate personal protective equipment. High concentration of this gas will create an oxygen-deficient atmosphere, creating the risk of asphyxiation. The symptoms described below are pertinent to hazards associated with this material as an inert gas.

    "EYE CONTACT: Release of a high-pressure gas may result in airborne objects.
    "INGESTION: Ingestion of this gas is not a likely route of industrial exposure.
    "INHALATION: High concentrations of this gas can cause an oxygen-deficient environment. The health effects associated with various levels of oxygen deficiency are described as follows:"…etc…

      Wrong document link above as the resource for the info on Krypton-85. Should be:

      http://www.lantheus.com/PDF/msds/XenonLantheusComplete.PDF

      More from this doc:

      "ROUTE OF ENTRY: External radiation hazard, inhalation.
      TARGET ORGANS: All
      SYMPTOMS: Exposure to low levels of radioactivity may increase likelihood of cancer and exposure should be should
      be kept to levels as low as reasonably achievable.
      MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: None are anticipated.
      "CARCINOGENICITY: Because it is a radioactive isotope, Kr-85 is considered a potential carcinogen."

      P.S. The above exposure hazards information is pretty similar to the affects of exposure to Xenon-133 gas which the PNW Labs told PNW residents they were breathing in and exposed their skin to 40,000 times background in March of last year.

      Surely in such huge explosions like at Reactor #3 at Fuku, more than just Xenon-133 made its way to the West Coast (as tests by the USGS and EPA found). Then why did the PNW only report on Xenon-133 and none other noble gases such as Krypton-85? And yet, we are now told we were NOT breathing in 5 hot particles a day in Seattle at that time, when we were in fact told this for the past year, up until today?

      Will you guys please get your stories straight, for goodness' sake???

    Krypton-85 has to come from fission. So are we seeing an increase in fission activity in (or below) reactor 2? Unless I am wrong, this would imply the mass in (or under) it is critical, or nearly so. Not good.

      It could be from current fission, or since there is no iodine showing on the chart, it could be some that was already made, has been trapped, and is now escaping. Of course, that begs the question, what is freeing it?

      Both have the potential for worry.


      Report Comment

    • GeoHarvey

      Since the other levels reported are not increasing, perhaps this is just a data blip. But it is worth watching to see if the xenon and iodine levels rise. Being gases (iodine sublimes at room temperature) these would be the first things to escape from somewhat buried corium.

      Iodine has been increasing in sludge. Tepco is simply full of it.

    Sorry to be reminding folks here but there is a cut down version clips from the March endoscopy of Unit 2 on last month's genera discussion forum. In respect of this thread, there are plenty of bubbles being outgassed from molten mobile stuff deep in the RPV: have a look if you like- it's only two minutes long fully captioned so no excuse not got time to see- or reply here if you want a fresh YT link (I'll check back from time to time).

    Not just a personal puff for a bit of work and any downstream criticism also welcome.

    Best wishes

    Isn't it incredible how they cannot measure so many radioactive elements inside a melted down reactor but can, on the other side of the planet, wiped off a pickup truck hood after a rainstorm in
    St Louis?

    How stupid are we supposed to be?

    The worst weather events come from Krypton 85 released from nuclear power plants and reprocessing and weapons facilities.

      Anne, where do you dig this stuff up from? You're amazing! :-)

      Thank you! Wow, this to me would go a long ways towards helping to explain the increased weird weather we've been experiencing since 3/11, yes? (That, and the use of EMF and chemtrail spraying any other host of "tools" we aren't privy to, that is.)

        WATK, I've been on this site a long time. Someone else posted this article originally, but didn't have access to the whole article. I was only a library assistant, but we got faculty library privileges and could keep them when we retired. I retired disabled in 1993. Anyway, I have a virtual library account on my computer at home, so I have access to a lot of articles.

          Also, a year before 3/11 in the spring I took an online computer course in beginning Physics. The regular day time job of the instructor who had gone to MIT and had a Ph.D. in physics was doing research on the weather and this person knew all about HAARP and the weather. This person asked me a lot of questions as I had already done a great deal of research on HAARP before when I was researching cell phone towers.

            Thanks, Anne. I am so impressed at the extent of your knowledge as well as your research skills par excellence.

            Cell phone towers…now there's a whole OTHER issue I share your concern over. (Wonder if they work in concert with the radar towers and HAARP too, or are they privately owned and operated by the cell companies for strictly cell coverage?)

    I might sound naive but TBH I wonder if disclosing data is not the new eye wash method for the public… I want to see results from them, clear, complete, concise and tangible achievements of how they deal with it.

    Plus we will never get the bigger picture if all they ever do if publish a fraction of what they know. those lists are only as good as the amount of info that we can get from them.. this should stop too. we are adults, treat us as such. thank you

      Here, here! I concur, Snowwy!

      We deserve nothing less than complete, transparent data and citizen oversight of the radiation testing process, to ensure it is indeed done properly and nothing is being hidden, or altered for public consumption.

    Excellent knowledgeable thread.

    Not to mention the role of Krypton 85 along with other noble gas releases in our very own ozone hole destruction. Wasn't that a very dramatic increase in the Arctic Ozone Hole last April a wonderful sight for sore eyes. These guys and gals are generating this stuff by the bucket full all over the planet at all their nuclear processing/generating/handling facilities.

    Energy and weather and then the constant fluctuation of our magnetic poles.

    Kind of makes you wonder what the Nuclear boys and girls are really trying to accomplish here on planet Earth. None of it sounds very good to me. Shut them down, shut them all down now!

    Krypton 85, my favorite. Used this gas to check computer chips
    for air tight seal after soldering them shut through a furnace.
    Bomb them at pressure, then detect the Krypton 85 leaking out.
    The detector station alarm went off when an employee had blood work
    done, some injection for X-ray pictures. We stripped him, but found him to be Hot, had to sent him to another station.
    Lurker out.
