La carte citoyenne de la contamination radioactive du Japon

We announce that the citizens' group in France "Echorchanges" succeeded to publish our book in French version.
We appreciate the great effort to Mr. Colin Kobayashi, who conduct this project for French citizens.
Also we appreciate Mr. Bruno Chareyron, CRIIRAD.

   Cette carte est l'aboutissement de six années de travail collectif de « Mina-no-data-site » en réseau des 33 centres citoyens de mesures de la radioactivité nées dans diverses régions du Japon après la catastrophe de Fukushima. C'est un résumé des résultats des mesures effectuées par 33 centres de mesures citoyennes à partir d'échantillons prélevés du sol sur 3400 lieux par 4000 volontaires entre 2014 et 2017.
   La version française a été créée en insérant des cartes de pollution des trois régions, Fukushima, Tochigi et Tokyo à partir de la courte version anglaise. La raison pour laquelle cette carte est importante est qu'elle mesure la radioactivité du sol, pas la dose aérienne, de sorte que vous pouvez voir la quantité de contamination de manière beaucoup plus fiable que la dose aérienne. La mesure est la valeur totale du césium 134 et 137, et la valeur pour mars 2011 est estimée et affichée par un calcul d'atténuation. Les cartes de surveillance des aéronefs publiées par le ministère de l'Éducation, de la Culture, et des Sciences et de la Technologie et la Commission de la régulation nucléaire sont converties en fonction des doses aériennes mesurées à 300 m au-dessus du sol et sont beaucoup moins précises que les estimations de Becquerel sur le terrain de cette carte de « Mina-no-data-site » qui est unique jusqu'à présent en tant qu'une carte en becquerel d'après échantillons réels.
   Le contenu comprend les trois cartes agrandies de Fukushima, de Tochigi et de Tokyo estimées pour mars 2011, uLes autres pages présentent la valeur estimée en 2020 et la valeur estimée pour 100 ans. Si vous allez sur le site <Minna-no-Data site>, vous pouvez voir toutes les cartes de mesures des 17 départements du Tohoku, Nord-Est du Japon.

[Request in front of IOC headquarters in Lausanne, Switzerland and report on interviews with IOC]

Junichi Onuma, who is a member of the Data Site Participation Measurement Room (Nagoya C-Lab) and a member of the Nuclear Citizens' Commission, was invited to a French citizen's organization in February, and hosted the Olympics with an English version of the map collection. And gave lectures in Switzerland and France. The report includes a speech in front of the IOC headquarters and an appeal to three IOC representatives in a conference room.

■ Request action before IOC headquarters and interview with IOC

Lausanne is a castle town of the IOC and has a lot of money from them.
Therefore, even if a stranger came and performed a protest, the town people would not easily come together.
But people came from all over Europe.
A total of about 60 people came from Paris, IPPNW doctors in Germany, and from all over Switzerland.

Well, after this protest, there was something unexpected.

It was the IOC that invited us, "Please go inside."
There was a limit of 4 people, but I had one of them, IOC meeting room,
I had the opportunity to spend almost an hour and listen to our request.
There were three people, a spokesperson, a physician and a head of the competition department.
What I talked about centered on the power points of the lectures being held on this expedition.
The interpreter was 15 minutes and a Swiss doctor talked about 5 minutes. I got an answer from the other party for about 10 minutes.

Leaving severe radioactive contamination and depriving displaced people of compensation and the right to immigration,
I told them that there would be no Olympics in a policy of returnless care.
Unfortunately, there are no photos or videos of the meeting with the IOC.
Some of the contents of the lectures of this expedition are recorded as videos, so I will introduce them.
This information was reported to the IOC.

It was impressive that the three members of the IOC took a lot of notes like shorthand.
The doctor also took notes while nodding many times.

One of the three people was not good at French, so I asked for an interpreter in English.
Perhaps such a story has never been heard from the IOC in Japan or from government sources.

The first word from the other party was that the Olympics could not be canceled,
Still, I got a comment saying "I'll tell you properly."
I will ask you to send me a note again from the interpreter who was present,
After such protests in Japan, they were actually invited inside,
It was even more surprising because there was nothing to listen to the story so carefully.

Request action before IOC

In addition, in Geneva, I stayed at a home where I was a staff member of the United Nations High Commissioner for Refugees Office.

Under Sadako Ogata, who has worked in Japan for three years, he protested that the World Health Organization (WHO) surrendered to the IAEA (International Atomic Energy Agency) (1959 Agreement WHA 12-40). Had been standing in front of WHO every day for 10 years
I am a member of a civil society called Independent WHO.
There is a detailed explanation on the meaning of WHO's yielding to the IAEA on this Independent WHO website ,
The point is that WHO and the IAEA will cooperate and collaborate with each other for the purpose of promoting the peaceful use of nuclear energy promoted by the IAEA.
In other words, it indicates that people's health issues and the economics of promoting the use of nuclear energy have become independent and influential.

In other words, WHO may consider the IAEA harmful to health caused by nuclear power (radiation).

Free use of Map of Soil Radioactivity at the time of the Tokyo Olympics

Starting from March 11, 2020, Minna-no Data Site will be offering free use of Map of Soil Radioactivity in 17 Prefectures in Eastern Japan at the time of the Tokyo Olympics

~The government of Japan has yet to conduct a wide range survey of soil radioactivity, but we did it and will offer free use of images of the results! You can use and modify the data for non-commercial use ~

Minna no Data Site (Everyone’s Data Site- Collective Database of Citizen’s Radioactivity Measuring Labs) will provide map data of “2020 Eastern Japan 17 Prefecture Radioactivity Measurement Map” (Japanese and English versions) free of charge with Creative Commons License (CC License) from March 11, 2020.

This map shows the estimated amount of radioactivity in the soil in the 17 prefectures of eastern Japan at the time of the July 2020 Summer Olympic Games, based on a calculation of how much the amount of radiation has decayed since initial soil radiation measurements were collected at 3400 locations in eastern Japan between 2014 to 2017.

At the same time, we will also be allowing free use of “Estimate of Radioactive Cesium Contamination over 100 Years”Map.


■Why we are offering the free data

The torch relay of the Tokyo Olympic Games will start in Fukushima Prefecture on March 26. Because of this, homes of the evacuees along the route are scheduled to be dismantled by March 25. In addition, the national government (lead by he Nuclear Emergency Response Headquarters) and Fukushima Prefecture have recently agreed to partial cancellation of the “difficult to return-area” designation of some parts of Futaba-Town, Okuma-Town and Tomioka-Town, as if radioactive contamination has disappeared from these areas, when in fact the radiation levels there are still extremely high.

In addition, the torch relay route was approved despite the fact that the air dose of some places along the route are as high as 0.77 μSv/h. The reason behind this decision was that the torch bearers will "not stay there long." Not only this air dose issue, surveys have also revealed that some locations along the route have soil radioactivity levels exceeding 1 million Bq/kg.

On the occasion of the 9th anniversary of the Great East Japan Earthquake that occurred on March 11, 2011, its commemorating events and vigils have been cancelled due to the recent coronavirus (Covid19) incident. As a result of considering what we could do facing this situation, we decided to release a map of soil radioactivity in the 17 prefectures of East Japan in July 2020 (downloadable version), in the response to many requests for the use of this map. We decided to provide the CC license ("Display — Noncommercial — Inherited") in order to offer them free of charge.


■Difference from the past

Until now, it was not allowed to reprint or use this map without permission. From now on, anyone who meets the following conditions will be able to use the publicly available data without prior permission or application.

We also granted a CC license to “Estimate of Radioactive Cesium Contamination over 100 Years Map” free of charge.

■What we expect for this action

This data is the fruit of the "East Japan Becquerel Measurement Project" conducted by citizens over a three year period from 2014 to 2017. It was then crowdfunded and self-published in November 2018. By providing free Japanese and English versions of some of the maps in the book at the same time, we will be able to create a base for the active use of the data collected by citizens in Japan, in hope that this information will be widely used by citizens and the media not only in Japan but also overseas to inform them of the actual situation of radioactive contamination caused by the Fukushima Daiichi Nuclear Power Plant accident.
