Follow-up to: Report: Plutonium ratio 200 times higher than gov't says -- Detection made 50km south of Fukushima Daiichi (RESULTS)

Title: Fukushima Isotope Data
Source: Global DIRT
Date: April 2011

This data was taken by a Global DIRT assessment team of the Fukushima I Nuclear Power Plant. Data was collected using a Berkeley Nucleonics Corporation SAM 940 Defender / Revealer. Data was collected up to within 50ft of the plant’s fence. The map below represents only readings which contained isotope levels (about 2000 of the 2900+ current readings). Be sure to check back as this page will be constantly updated.

Measured in CPS (clicks per second, see YouTube comment below)

Title: Fukushima Radiation from Tepco Nuclear plant 25km out
Source: Global DIRT
Date: April 11, 2011

Question: Oi, could you put some units on your map page? Numbers by themselves aren’t terribly useful, or meaningful.

Answer: the units are in CPS which measures background radiation, the CPS the unit receives is in the beginning, then the rest per isotope. The best way to calculate dose rate from CPS for the average human would be .87 per thousand CPS.

    TOMORROW IS YELLOW FRIDAY!!
    EVERY FRIDAY SHOULD BE YELLOW HERE ON OUT!!
    Tomorrow, it is a new "Yellow Friday" against the nuclear.
    A year is already happening, but we do not relent!
    Wear yellow, the color of the antinucleaire movement and talk about around us…
    Proclaim that next Monday, March 26, 2011, the last reactor of the tepco (Kariwa nuclear power plant 6) will be adopted for periodic review.
    And on any given empechons!
    (manif and delivery of complaint was the tepco – Niigata Office, Monday 26, 9 h a station of Niigata, 11: 00 a tepco Niigata)
    Monday, 26, a single reactor be still walking (on 54) – Tomari 3.
    The evidence will be made that we do not need this energy demoniaque!
    Proclaim the truth everywhere in the world! (Translated by Bing)

      Great idea! Yellow Friday – I might adopt it around here!

      Thanks Whoopie. Because of your post I wore a yellow tee today on my weekly trip to town. Didn't see anyone else wearing yellow – didn't really expect to, since the idea is so new.

      "energy demoniaque" – there's a phrase that should work in a lot of languages.

      Great idea. I hope it takes hold.

      "Hey, what's with all the yellow clothes?"
      "It's for Fukushima. Haven't you heard?"
      "Phoo who?"
      Pounce!

    Those are really scary numbers, I think. The story headline at 8,000 CPS, the map fragments showing over 63,000 CPS. Unless those are typos, that is counts per second, not per minute.

    By contrast, the radiation network realtime map right now is showing 50 stations, mainly in the US, with an average count of 24 CPM (counts per minute, not second), and the highest one I can see is 58 CPM.

    Huge difference for those closer to the source, it seems.

    Well cps is the same as Bq

    Now I wish he'd have given the units for his dose rate conversion equation CPSx0.87=dose rate

    0.87×60000 is about 56000 but what units???

    Look at the dates, folks!

    The measurements were made in April, 2011. I'm dubious b/c there are no Iodine-131 readings at all or other isotopes (except for Cesium). It's hard to draw any conclusions without knowing what kind of analysis has taken place other than the CPMs from a hand-held counter.

    The Nuclear Industry loves the fact that the units are confusing because it makes it easier to refute them…

    Suggestion, pick one easy to understand unit system and then require folks submitting data to use that system or at lest convert their data to that system… Problem solved

    Please put on your thinking caps and suggest what this system should be!

    This study might be useful as a great comparison of radioactive pollution:

      Majia beat me down before and I believe it is more like 1750 lbs.

        Where can calculations be viewed? Your figures will be inserted in total, if a link is available.. Feel free to comment below blog post to add new or different information, and it will be adjusted.

          Are you willing to share your data for your estimate of 600 tons? I need to know!

          here is what I know:

          HOW MUCH FUEL: "The Daiichi complex had a total of 1760 metric tons of fresh and used nuclear fuel on site last year, according to a presentation by its owners, the Tokyo Electric Power Company (Tepco).

          The most damaged Daiichi reactor, number 3, contains about 90 tons of fuel, and the storage pool above reactor 4, which the Nuclear Regulatory Commission’s (NRC’s)

          Gregory Jaczko reported yesterday had lost its cooling water, contains 135 tons of spent fuel. The amount of fuel lost in the core melt at Three Mile Island in 1979 was about 30 tons; the Chernobyl reactors had about 180 tons when the accident occurred in 1986…." http://news.sciencemag.org/scienceinsider/2011/03/how-much-fuel-is-at-risk-at-fukushima.html?rss=1

          Majia, No Contest! My last memory here was 600 early spring. Once I found out we blew a hole in or upper atmosphere I realized the weather implications. Did not follow lbs. released because of faulty data, lies, and depict by Nuke Industry. After initial explosions, estimations, observations. The implications alone from 600 are not controversial on impacts to biology. Like saying whats the differences between Google and Tens. In Nuclear technology, I believe nearly equal the relation in biology.

      Interesting facts about plutonium and of course talk of testicle inflictions casts doubt on the survivability of the human race.

      But never fear! The Dr. Strangeloves have procured vast amounts of sperm from pre-Fukushima donors and stored in freezers for the propagation needs of the next hundred millennia. No efforts were spared to get the best specimens for the test tube babies of the future. Now please take your Soma and go watch your home wall screen news. We may have need of your help to track down a dangerous subversive. When you can help us just press your left thumbnail to activate your 911 head phone call. That is all… Have a nice day!
