The accident of the Fukushima Dai-ichi nuclear power plant of Tokyo Electric Power Cooperation (TEPCO) after the great east Japan earthquake (11 March 2011) elevated the background level of environmental radiation in Eastern Japan. Around the Tokyo metropolitan area, especially around Kashiwa and Nagareyama cities, the ambient dose equivalent rate has been significantly increased after the accident. Responding to strong requests from citizens, the local governments started to monitor the ambient dose equivalent rate precisely and officially, about 3 months after the accident had occurred. The two cities in cooperation with each other also organised a local forum supported by three radiation specialists. In this article, the activities of the local governments are introduced, with main focus on radiation monitoring and measurements. Topics are standardisation of environmental radiation measurements for ambient dose rate, dose mapping activity, investigation of foodstuff and drinking water, lending survey meters to citizens, etc. Based on the data and facts mainly gained by radiation monitoring, risk management and relating activity have been organised. ‘Small consultation meetings in kindergartens’, ‘health consultation service for citizens’, ‘education meeting on radiation protection for teachers, medical staffs, local government staffs, and leaders of active volunteer parties’ and ‘decontamination activity’, etc. are present key activities of the risk management and restoration around the Tokyo metropolitan area.

    They can measure radiation and talk about it. But as for improving things, that'll be when the world outlaws nuclear power plants. If we don't do this, other countries will fall victim, and be helpless just the same.

    Atomic particles are so small it is pointless to try and decontaminate. You would have to filter and treat billions of cubic feet of air and scrape the ground for fallout for eternity all while pumping nitrogen into a melted core structure where no one knows where it's gone. This has already happened. The fuel's gone deep into the ground as the first signs of radiation sickness spread across a swath of 800km surrounding the plant. Ground water is at an unknown level of contamination at this point in time and is known to have started affecting livestock in the Fukushima area. The clock is ticking for every sign of nuclear fallout in human society. The scary part is that no one seems to be reacting in a rational way to take emergency measures to entomb. Instead it's like they are waiting for the containment to breach and have another nuclear blister explode in the face of mankind . TEPCO is a mad dog playing with 7 billion lives and a tiny blue planet. Yokohama Japan reading .500mSv on the regular. This is where thyroids start to decay watch for the walking dead symptoms of radiation sickness. Nosebleeds, hair loss, shaking, vomiting, blood in urine. The list goes on. And that's all for the broadcast folks, it's been nice…and I'm your host…Three dog!!! HooOOoOOooOO

    Burning nuclear waste in incinerators all over Tokyo, and dumping nuclear waste into Tokyo Bay isn't going to make the radiation levels go down.


    "The two cities in cooperation with each other also organised a local forum supported by three radiation specialists." Had they not taken the initiative to do the testing themselves, TEPGOV would've continued denying the facts. Lesson here is no governments are looking out for the people. You have got to bypass them if you're to survive…

    It all sounds like a big example of 'downplay and distract.'

    3 Chernobyl for Tokyo.
    Only 1 small to medium incident is needed to cause consterning health effects among the population.
    But Tokyo is faced with 3 medium to high incidents.
    It would be a miracle if this has no medium to major health effects on the population of Tokyo.

    1- Fukushimia reactor explosion dust contaminates Tokyo
    2- Tokyo gets contaminated by the burning of contaminated debris
    (which, in itself, is a nuclear incident capable to cause
    health effects to the population)
    3- On-going Fukushima emissions reaching Tokyo, and to continue reaching Tokyo when the winds blow toward the city. After 5 or 15 years, the total of emissions is equal to that of another Fukushima explosion.

    Any of these 3, in itself, is capable and will have a significant health effects. Add the 3 together.

    How many: thousands of square km must forever be taken out of production; births interrupted; oceans hopelessly lost forever; deaths, all because of this diabolical technology?

    We must have a greater visionary to come to the fore! We won't get there with the money ties of corporatism corrupting so many.

      Yes Greed and corporate corruption has paid the way for many disasters including our government which is also very greedy and corrupt. I find the transformation of the GOP very upsetting and unsettling.


        hate to say moonshellblue, the GOP has been on a downward slide for close to thirty years now. When the parasites completed their takeover of the Democratic Party, they sent 'emissaries' into the Republican camp. They used the Bush family as their front. The two major political parties are no longer concerned with the will of the American people or the welfare of this nation. Other than (marginalized) third party candidates, we have no one speaking to real issues…

        Yes, MoonShell Blue…listen to Aftershock. The USA has only one corporate dominated party. Wall St. calls the shots and the Dems & Reps just do what they are told.

        The system no longer works. Stop believing in it. Do not expect hope or change from either party within this stanglehold duopoly.

    Have a friend visiting Tokyo wearing a RADTriage Badge. She is visiting a sick friend/family member in the hospital there. Will see what she registers when she gets back in a few weeks.

    • moonshellblue moonshellblue

      Oh jec, please keep us informed as my brother was just screaming at me how radiation can't be that bad in Tokyo because they are flying commercial jets in and out of the area and so on. Wow my ears are still stinging.

    Ningbo intercepts Fukushima contaminated metals

    September 20, 2012 by Editorial Staff

    China/Japan: The Chinese coastal city of Ningbo has intercepted 9.26 tons of radioactive scrap metal, China Central Television (CCTV) has reported. The source of contamination is said to be Fukushima in Japan where the nuclear accident occurred in March 2011.

    Radiation levels soared 28% above those allowed by the Chinese government, CCTV reported. This information contradicts a previous on-line claim that over 1000 tons of contaminated metal had entered the port city with a radiation level roughly 200% over the national limit.

    According to the television network, the metal was imported by Ningbo Huanjin Recycling Metal Co. Ltd, which belongs to Japan’s Taiwa Trade Co Ltd. Putting the date of arrival at around May 13, CCTV states it was then discovered by the Ningbo Entry-Exit Inspection and Quarantine Bureau. It was due to be re-directed to Japan – together with 1117 tons of non-contaminated material that had accompanied the shipment – on June 23.

    The possibility that Taiwa Trade Co Ltd had intended to ship contaminated metal to China was dismissed out of hand by a company official. It was added that the scrap originated in Chiba, a sub-national jurisdiction in the Tokyo area, and that the contaminated material might have come from dismantled car parts from Fukushima which happened to ‘slip through’ the…
