Title: Radioactivity concentration of Morioka, Iwate Prefecture
Source: MEXT
Author: atmc.jp
Date: March 26, 2012

Focusing on the microsievert level is not the best use of the data, as monitoring posts are located 50 feet or more above the ground.

Levels also spiked in Yamagata, Miyagi and other neighboring prefectures:

    is it just me or has japans radiation measurements have dropped alot since they turned the other reactors off?? odd that? or is there a covering of clean snow everywhere? or are the readings seriously bumped down??? hmmm?

      Arclight, I'm not sure about a covering of clean snow to reduce figures. I think Japan have resorted to using an extra thick carpet to sweep those figures under!

        @ goathead
        what about the fact that about 52? reactors closed down and not spewing? would that do the trick

        like the carpet analogy so much im going to say they do both!

        they are getting one third (minimum) of the readings than in the uk and most of europe (sort off) and thats according to the recently defunked eurdep!! ??

        no nukes :) :) :)

        swtch em off now!!

  • In the best shielded location in germany we dont get a value below 0.06 uSv/h — maybe the values are relative ?? The groundlevel is not adjusted ???
    But even with the peaks I consider moving to Japan, seems to be lower than in Germany (we got a lot of CS137 from Tschernobyl)

    • Just heard from my collegues, its seems to be a special gamma indicuator for nuclides for breathing oder eating — Therefore it cannot be compared to the ground level — maybe someone else can explain this more detailed.

        nice post rdklein!

        looks like they come up with a new measurement just for fukushima.. how novel!! eaty breathy detector!! want one!! … what does it do exactly?? :) hope someone knows!! i bet richard wakeford is behind this because he was posting papers asking for a new measurement to take into account "internal doses" and he was at the fukushima symposium (with a friend/fiend :) ) richard bramhall from the llrc was battling with some other papers he was posting i think!

        wonder if this is the new measurement system posited by richard wakeford?? nice they just use it and dont explain what they are up to!! richard wakeford is a sneaky little bugger.. or did someone nick his idea?? hmmm?

        ho hum..

        another measuring system coming to a continent near you soon.. maybe wakeford is going to do ANOTHER measuring system?? especially for the uk! that would be confusing???

        we will have to wait and see!! :/

          anyone got there heads around the term million billion etc in connection with the uk/scientific and american versions of these measurements?? they are highly confusing too!!

          this man is no fiend!! he was not at the fukushima symposium… just to clarify.. me bad grammar :(

          richard bramhall has been battling wakefords silly dose concepts and allowable statistical casualties (as long as the figures are low enough) big up the good richard bramhall at the LLRC

    The rooftop readings do not reflect the radiation on the ground, which people are breathing in and tracking into their homes… but they do give a good idea of fresh Fuku releases. The latest spike is due probably due to coriums #1 and #2 which have been acting up lately, flame and steam visible from the ground, heat and hydrogen building up in #2.

      the over averaged software on eurdep only responds to large contamination clouds and then massively under-reports the values!

      i am sure this system is the same.. however safecast more than agrees with these sort of values.. and they seem to have lower than 0.02 in quite alot of japan or are they not monitoring?? i think it is because of the other reactors not working.. !!! wowzer!

      and heres safecast

      thats soooo looow !!

      im jealous!

      apart from the really hot bits near daichi of course! and airborne particulate issues and the spring melt :(

      1 year with no nukes nearly!! keep it up japan and you might stand a chance!!

      banzai!

        big correction!!

        the reading of safecast is mostly above 0.10 mcSv/h rising to 0.19 mcSv/hr.. i dont kno what the averaging system is nor how sensitive the software is to small clouds of contamination..

        as you approach the daichi it obviously rises.. this is actually comparible to london except that 0.05mcSv/h hasnt been seen for some time in london (briefly last summer)..

        so to affirm that my statetment of "how wonderfully low it is " is complete rubbish… its the same as london which is on pollution alert! except for the cover up!

        wonder how the rest of japan is doing though.. i did find a couple of readings on safecast that were 0.05 mcSv/h but the whole of japan isnt covered??…
