Breaking News!
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 theTokyo 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 datafor non-commercial use ~Fukushima, Japan, March 11, 2020 — Minna no Data Site (Everyone’s Data SiteCollective Database of Citizen’s Radioactivity Measuring Labs) will provide map data of“2020 Eastern Japan 17 Prefecture Radioactivity Measurement Map” (Japaneseand English versions) free of charge with Creative Commons License (CC License)from March 11, 2020.
This map shows the estimated amount ofradioactivity in the soil in the 17 prefectures ofeastern 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 Japanbetween 2014 to 2017.
At the same time, we will also be allowing free useof “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 ofFutaba-Town, Okuma-Town and Tomioka-Town, as if radioactive contamination has
disappeared from these areas, when in fact the radiation levels there are still extremelyhigh.
In addition, the torch relay route was approved despite the fact that the air dose ofsome places along the route are as high as 0.77 µSv/h. The reason behind thisdecision was that the torch bearers will "not stay there long." Not only this air doseissue, surveys have also revealed that some locations along the route have soilradioactivity 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 beencancelled 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 theresponse to many requests for the use of this map. We decided to provide the CClicense ("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 is CC License?
By granting a CC license, authors are free to distribute their work while retaining their
copyright, and recipients are free to redistribute, remix, etc., within the terms of thelicense.
1.Redistribution may be made by anyone for non-commercial purposes only, including"Minna no Data Site" and title credits.
2.Users can add their own data or information to this data and modify it to create newdata.

3.Inclusion of the Creative Commons logo is a condition. Sources on the map cannot
be deleted.

■What we expect for this action
This data is the fruit of the "East Japan Becquerel Measurement Project" conducted bycitizens over a three year period from 2014 to 2017. It was then crowdfunded and selfpublished in November 2018. By providing free Japanese and English versions ofsome of the maps in the book at the same time, we will be able to create a base for theactive 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 informthem of the actual situation of radioactive contamination caused by the Fukushima
Daiichi Nuclear Power Plant accident.

■Outline of Group
Organization Name: Minna-no Data Site (Everyones’ Data Site)
Co-representatives: Hiromi Abe (NPO Fukushima 30-year Project), Shoko Onuma (Tokai No Nukes

Outline of the organization:
A network of 31 citizen radioactivity measurement offices across Japan. Radioactivity measurement dataof food and soil in each measurement room is consolidated into a single platform, and a website "Minnano Data Site" is operated so that anyone can easily search and browse it.
December 2017: Won the grand prize of the Information Distribution Promotion Award from Kazuo
Hizumi.
November 2018: We self-published "Illustration 17 Prefecture Radioactivity Map and Close Analysis ".
18,000 books have been published. (As of March 2020)
July 2019: We received the JCJ Award from the Japan Congress of Journalists.
September 2019: Citizens' Radiation Data Map of Japan (English Digest) was published
