NHK reports 57.5 microsieverts per hour detected just 25 km from Tokyo — But is it from Fukushima meltdowns?

Published: October 21st, 2011 at 12:12 pm ET


CHIBA, Oct. 21NHK (Japanese only) is reporting on the discovery of 57.5 microsieverts per hour (µSv/hr) at a vacant lot in Kashiwa, Chiba.

According to Mochizuki’s post on the article, citizens measured 20 µSv/hr on October 18 in an empty area surrounded by houses/factories and reported it to the city government.

When they dug into the ground 20cm deep, the reading was 57.5 µSv/hr.

The city says it’s difficult to assume a link to the Fukushima meltdowns because of the distance underground.

Mochizuki notes that “radioactive particle might have sunk” or radioactive debris from Fukushima may have been secretly abandoned in the area.

    That’s right, it’s completely inconceivable that radiation could wash downward from topsoil. Inconceivable. The only possible source of this high level of radioactivity is clearly either old radium bottles or possible glow-in-the-dark watches.

    Anyone else vote for a Nuremberg style trial for upper level government officials….

    502.32 milliseiverts a year…or .5 Sieverts a year. Man. That’s crazy dangerous.

      Not once the Japanese government resets acceptable levels to 2000 mSv/year. Then it’s fine. Of course, they’ll release it as .02 kSv/year, which looks way better.

    The doctor thinks that vacant lot would be a perfect place for one of my new chain of Happy Attitude Daycare Centers.

    Investors, please feel free to contact me.


    • Doctor, your poor attempts at humor exasperate an already desperate situation.

    • Dr. McCoy

      I’ve seemed to have pissed off the religious right be insisting that we stick to science, so I thought that I’d give humor a try. Jeeze.

      • I’m happy the affair is over. A most annoying emotional episode.

        Perhaps a balance is called for Doc. I agree the attack on you for believing in science was unwarranted and unduly harsh. We will need both the strength of faith and science to get through the nuclear nightmare that is coming down. Now is not the time to be divided.

        Even Spock would agree that the joy of creation is in it’s infinite diversity, but more importantly, the way our differences combine to create meaning and beauty.

        • Dr. McCoy

          I appreciate that nohobear. I believe in the separation of church and state and I believe that there are plenty of outlets for those who are believers to express themselves. Most followers of that mortal man from Galilee are alright but there is a large contingent who are intollerant of people like me who speak the actual truth. As John Lennon said, whatever gets you through the night, it’s alright.

          It ain’t easy being green…

    Send every cargo ship, air craft carrier, airliner, and resource available from any countrys command and control center to evacuate now. Get them out yesterday! We a f’d up. Let’s deal with it now.

  • CB CB

    Make preparations to include the population of Japan, to any county willing to accept them. Create large spaces and shelters, and bend red tape rules on Immigration laws. People send nonperishable food to banks for help. Step 2 needs attention now.

    @ faraway fan

    Yes, these are crimes against humanity. Not just the Japanese, but all of the governments who are joining them in the three little monkeys’ see/speak/hear no evil/no problem/cover-up.

    “Problem? We don’t see no effing problem – when it comes to a few million human ‘useless eater’ deaths caused by our nuke power industry…”

    The law is just words on paper… without enforcement. When enforcement is ‘captured’ – then we got no enforcement – just words on paper.

    We need some brave Japanese or other adventurers / heroes to travel into Daini and Oganawa to do filming/testing. They will need to prepare and get in and out, but the world needs to know the status of those two damaged plants. Im willing to bet Daini is coming unglued and possibly China syndrome. Also willing to bet Oganawa is releasing.
