Radioactive materials spread from Fukushima plant
May 28, 2012

Japanese scientists say radioactive substances from the Fukushima Daiichi nuclear power plant may have been dispersed all around the globe in about 40 days.

A research team led by Akira Watanabe, a Fukushima University professor and meteorologist […] say the overall density is declining, but continues to rise and fall alternately in a 40-day cycle.

They say radioactive materials from the Fukushima plant fell to the ground in various parts of the world, carried by atmospheric air flows, and then gradually decreased.

    "The researchers say the overall density is declining, but continues to rise and fall alternately in a 40-day cycle."

    What would cause this sort of 40-day cycle? I wish we could have more information so we could better gauge when there are likely to be higher or lower concentrations in the air.

      Iam35. Good question. It caught my eye also, noone seems to have answered it here. 40 Day Cycle! What is it?

      The only thing I can think of is that they are implying that the radiation plume stays somewhat intact, and that it takes forty days to circumnavigate the planet. I would think that by now the originol plume has spread out, dispersed enough after a year, that this could not happen.

        Through the changing seasons with different weather patterns this seems highly unlikely. But it should be easy to confirm or disprove by going to Radnet and plotting the high reading for each day for the last year. graph it and look for a recurring wave on the graph.

    just follow the jet stream, when its over your area, if its raining -> high exposure. if its nice out -> still being exposed but not as bad

    remember, this thing is just continuously pumping out rads still, so every day its just dumping more shit into the atmos.

      Thanks. I have been watching the jet stream (and of course the rain), but I don't understand the "40-day cycle"; does the jet stream follow such a cycle?

        As for Radon, it is now my opinion (Amateur researcher.) that it could be the direct result of the vast quantities of Uranium close to the surface of the earth.

        If the Uranium is left in the ground, most of decays before getting a chance to make it to the surface.

        It follows that if it is on the surface of the earth, due to meltdowns and such, then the Radon has a head start and can go further before decaying.

        "Radon (play /ˈreɪdɒn/ RAY-don) is a chemical element with the atomic number 86, and is represented by the symbol Rn. It is a radioactive, colorless, odorless, tasteless[1] noble gas, occurring naturally as the decay product of uranium "

        We can look forward to more Radon in the future with increasing concentration in my opinion, so that when we detect Radon in the rain spiking, those will not be able to say "it is just Radon washout" but is the added result of Uranium close to the surface of the earth and not deep down where most does not get a chance to surface..

        What do you think??

    This may be OT, but I ran across this in an ex-skf article today:

    "When Goshi Hosono as a personal assistant to then-Prime Minister Kan went on a TV program in April 2011 and said "We knew it was a meltdown but we just didn't feel like telling people", there was hardly any reaction from the media or the general public".

    Now, admits to meltdowns in Fuku1,2,&3, but claims the coriums are still contained. These people are liars and criminals. Mr. Hosono should be put on the Fuku cleanup crew as punishment for his crime.

    The fact that they are constructing a cofferdam between the reactors and the Pacific to keep highly radioactive groundwater that flows around Coriums 1,2,&3 from reaching the Ocean should tell us a lot about where Coriums 1,2,&3 really are.

    Meanwhile, the entire Pacific Ocean is filled with Fuku cesium from surface to bottom, from Japan to the US to Australia. Earth's atmosphere is filled with Fuku radiation from the surface to the stratosphere. And we find that the tuna and all the food we ate last year is contaminated by Fuku radiation. And the FOOLS in the Japanese government JUST DIDN'T FEEL LIKE TELLING PEOPLE what's going on? Twilight Zone!

    It's obvious in Longmont, CO that the cycle is MUCH shorter than a 40 day cycle. Check out the forum to Post your radiation readings.
