Cathode Long “rings of the capital of contaminated food の と の radioactivity terror”, Weekly Asahi, September 23, 2011:

Meltdown temperature of the fuel in nuclear reactors in Fukushima in March, therefore, far more than 2000 ℃, had been considered from 4000 ℃ to 3000 ℃. Boiling point, 184 ℃ and iodine, 671 ℃ cesium, strontium since 1382 ℃, radioactive materials are dangerous, but far beyond the temperature was almost entirely vaporized. Even the plutonium, the boiling point is lower than 1400 ℃ 3228 ℃ than molybdenum. If so, of course, strontium and plutonium are particularly significant influence on internal exposure, and was released to the mass gasification, I believe.

Translation of Asahi report via Fukushima Diary:

Science journalist Hirose Takashi

In March, fuel rods started meltdown in the reactor.They became hot as 4000℃, which is hot enough to make most of the radioactive material evaporated.

Especially plutonium and strontium were evaporated, spread around as gas. [...]

  • WindorSolarPlease

    So much is going on!!
    Plutonium, strontium and so on spread around as gas
    No measurement tool???
    Valves are broken???
    Tepco doesn’t want to check the whole plant first???
    No defense force incase it explodes???
    Lifting the mandatory evacuating area???
    Water purifying system is broken
    Hydrogen is still being produced!!!
    Melted fuel rods active
    Still HIGHLY radioactive.

    Workers at Japan’s Fukushima plant say the ground under the facility is cracking and radioactive steam is escaping through the cracks.
    Would that also mean that Hydrogen would eventually follow, escaping through the cracks?

    This is an unpleasant hypothesis. Unfortunately it sounds quite plausible. Not just particulates, not just radioactive steam but actual vapourised radioactive isotopes. I’m presuming all bets are off regarding how high and how far that stuff could go. And how it could interact with the environment, flora and fauna, and of course us.

      got a jet stream model that can show us how it concentrates plutonium in st louis?

        Hi acid lab, not sure about St Louis specifically but any repetitive weather pattern (due for instance to terrain, ocean temperature etc) has the potential to transport and deposit more than the average saturation of material (in the atmosphere) to a particular location over time.

        The beach is one example of this type of system, where you find an abundance of material which deposits in high concentrations in a specific area even though the material is much more evenly distributed throughout the ocean.

      Another reason to believe plutonium went into the stratosphere and is now circling the planet.

      thanks for the link, jon. i’ve gone through that guy’s site rather extensively… i’ve even watched all of his recent videos in full.

      it’s my opinion that he’s a total crank. his consistent and ridiculously high readings for the st louis area every time it rains are comical. his theories regarding radon, jet stream transport/concentration, etc. are bizarrely incomprehensible in his videos and posts.

      Q: how is it that st louis gets the highest readings in the united states?

      A: because that’s where potrblog lives.

    As a child, I loved to play in puddles after it rained. I loved to stand out in the rain and dance around. Now, sadly, I am scared of rain. I am afraid to go outside when it rains. I tell my husband to stay out of it, and if he gets out in it, I make him wash everything. What I are my children going to have to do if they live long enough to become adults?

    So what happens to plutonium/strontium after it has “evaporated.” I have seen some experts claim that, in its solid form, Pu is relatively heavy and less likely to travel very far (compared to iodine and cesium). I assume it can travel farther in an evaporated, gaseous form? But how much farther could it travel and how long would it remain in this evaporated state? Would it eventually return to its solid form? Could condensation form around it and eventually pull it out of the air as rain?

    I know there was controversy about whether strontium or plutonium was found on the west coast. I think some of Berkeley’s data seemed to indicate some strontium (or was it plutonium) was detected, but, as I recall, they said it was below a certain level that they required it to reach in order for them to officially say an element was detected. I wonder if being in this evaporated state could have anything to do with those findings?

    As far, as I can remember Mr Busby said that traces of plutonium from Fukushima were detected in UK in on of the old videos. High energy atoms tend to travel higher and at longer distances, than low energy ones. Jet stream can carry them if the initial energy of the particle is enough to reach it. Plutonium oxide is formed and in this form, though in in lower quantity than lighter particles, it travels.
