[Official monitoring post] “Comparing with personal dosimeter is banned”

It’s widely known that the official monitoring posts manipulate the radiation reading to make it look less than actual.

(cf, Japanese gov admitted monitored radiation level is indicated to be 10% lower than actual [URL])

The radiation researcher of a citizen posted a video on 3/21/2013. In this video, the researcher states,

“(In Hitachi city Ibaraki) we were told not to compare the radiation readings of individual geiger counter and official monitoring post and take a video of it within the area by Ibaraki prefectural staff.”

The reason is not known.

In this video, the radiation level indicated by the official monitoring post is significantly lower than the mobile geiger counter, which is already traditional. The mobile geiger counter showed 0.15 μSv/h, where the official monitoring post shows 0.05 μSv/h.

The used mobile geiger counter is rented from the city government themselves.

[Bornes de surveillance officielles] “Comparer avec des compteurs personnels est interdit”


Il est très connu que les bornes de surveillance officielles manipulent leurs mesures pour les minimiser par rapport au réel. (cf. Le gouvernement japonais a admis que le niveau de radioactivité indiqué par la surveillance est de 10% inférieur au réel)

Le contrôleur de radioactivité d’un groupe civil a posté une vidéo le 21 mars 2013. Dans cette vidéo, il affirme :

“(dans la ville d’Hitachi de la préfecture d’Ibaraki) on nous a dit de ne pas comparer le relevés de radioactivité des compteurs Geiger individuels avec celles des bornes officielles de surveillance et de ne pas en faire de vidéos dans la région.”

La raison n’en est pas précisée.

Dans cette vidéo, le niveau de radioactivité donné par la borne de surveillance officielle est grandement inférieur que celui donné par le compteur Geiger portable, ce qui est bien classique. Le compteur Geiger portable affichait 0,15 μSv/h quand la borne officielle affirmait 0,05 μSv/h.

Le compteur Geiger portable est loué par la municipalité elle-même.

    1. ” The arrogance is shocking ! ”

      Close but no Cigar !

      Here is the ‘bull’s eye’ :


      The Charges :

      1) Overall , How would you call someone that leaves his dirty laundry , radioactive environment and corrupt society for You to clean and Fix ?

      2) How would you call someone that brings you in this world without any trace of Responsibility , to the extend that presently parents can not Possibly guarantee None of the Triangle of Happiness points to their children ? ( Health , Financial and True Love )

      3) How would you call someone that brings you in this world fully knowing and guaranteeing that you’ll die , doesn’t even matter how ? And that includes breaking your heart by seeing your lover die , if you were lucky to find a true one .

      4) How would you call those f**kers that inspite of all the obvious problems , from on-going wars to pollution , corruption and Organized Crime , they do Nothing , voting on-and-on for the same sneak-oil-salesman , and watching sports/fashion instead of getting off their ignorant asses ?

      5) And how would you call this person who , after the devastating screw-ups above , Demands , NOT EARNS Respect to the point that psychologically is pressurizing you in buying a Card for his/her f**king birthday !!

      6) And how would you call someone THAT ROLLED THE DICE WITH YOUR LIFE ?

      Now you see why it is so Truthful , ON MERIT , to Acknowledge the present reality by Stating Confidently : “ Show me a Parent and I’ll show you an Asshole ! “

  1. It might sound a bit weird and extreme, but both geiger counters are probably right.

    Both values are normal readings for background radiation, because everything between 0.2 uSv/hr and 0.01uSv/hr are normal readings.
    With radiation levels this low, the reading you get in a certain spot could be far lower then what you’d get 3 meters further.

    Chances are also, that the government meter is already calibrated to the background radiation where the personal geigercounter isn’t.

    So we have 2 possible explanations for this difference and with these low levels, we have nothing to worry about…. again….

    You only need to panic if the difference between levels would’ve been higher, like 0.7 uSv/hr on the personal dosimeter and 0.05 uSv/hr on the government meter. So right now, nothing is happening there, because both meters are well within the safe margin and the differences in the margin of error.

    DON’T PANIC! (over this one at least, the other stories about Pu 241 being found are a completely different story)

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
