March 2011 The Great East Japan Earthquake occured

The occurrence of the Tokyo Electric Power Fukushima Nuclear Power Plant accident and the birth of many citizen measurement rooms

On March 11, a major tsunami hit the Fukushima Daiichi Nuclear Power Plant with the Great East Japan Earthquake, and all power was lost. By the next day, March 12-15, Unit 1, Unit 2, Unit 3, and Unit 4 explode, and huge amount of radioactive materials are widely scattered in the living environment.

The government's evacuation order was also reversed.

Radioactive iodine and radioactive cesium exceeding standards from food and water as well as air dose were detected, and citizens' lives fell into confusion.
Is food for children to eat safe? Can a farmer ship this crop? Each citizen was to face "radioactive material" that he had never known before. Even if you wanted to measure it, it was a measured price of several tens of thousands yen per sample in a private company, and it was difficult for citizens to feel free to measure what they wanted to know. Therefore, "measurement rooms" by citizens began to rise around the country. Measurement of food, space, surroundings such as the soil began by oneself, and it came to perform measurement request from the general public inexpensively.

September 2012 "Everyone's data site" concept is born

The idea of wanting to create a system to unify measurement data and display it on a map in an easy-to-understand manner at a research exchange meeting by grantees and applicants related to radioactivity measurement conducted by the Takagi Jinsaburo Citizen Science Foundation It came out. Based on this, the current “Authorized Non-Profit Organization Fukushima 30-Year Project” “Children Mirai Measurement Station” “To Connect to the Future” Tokai Net Citizen Radioactivity Measurement Center (C-Lab) “Jiro Takagi Citizen Science Foundation” The project was launched with a focus on "Let's build a database of citizen's radioactivity measurement room in full scale". In September, we decided to name it as "the data site for everyone", examined the organization's system, and started to study and develop specifications.

January 2013 "Everyone's data site" kickoff meeting held

We created our own food classification and made it into a database, and at first we built a system for the purpose of being able to register, search and browse data on "food" that most citizens needed at the time. Since the data registered in the database needs to be accurate measurement values, the participating measurement rooms have their own verification system, and a rule has been established that groups that have cleared measurement accuracy can participate. We held a kickoff meeting for the measuring room to show off this first pilot system.

March 2013 Unveiling site for the first time to the public

A "Startup Gathering Meeting" was held to show the public that the database was created. The application of the participating measurement room was also accepted, and the input and publication of the measurement data began in order.

March 2014 Implementation of a wide-range measurement project for food

Conducted a project to measure the trend of “Take noko / Shiitake” extensively.

March 2014 Start the concept of soil measurement project

Since the next thing of food is considered to be soil, we start the concept. Based on the “Soil survey project Iwate” developed independently in Iwate Prefecture from 2012 to 2013, we will measure, record, and map soil as a data site for everyone using a more unified method. is what happened. We will prepare for the study of concrete measurement range, scale and method, financing, standardization of collection method, result input and development of browsing system etc. Recruit measurement rooms to participate in soil measurement projects.

September 28, 2014 Holding Information Exchange Meeting in Measurement Room

Twenty participating measurement rooms meet in one hall to exchange information and share information. Publish a blueprint of the soil measurement project and discuss.

October 2014-Let's know! Let's measure! Connect-Let's start the "East Japan soil becquerel measurement project"

If you receive measurement fee, you will not expect active collection from everyone in the afflicted area, and we apologize for getting money from the afflicted area, so the measurement fee will be free and we will raise funds independently. Start the project as

March 2015 Publicly call on citizens to start soil measurement project

Soil measurement project "kick off meeting" held. Call on citizens to start the project widely. Call for organizing collection workshops in 17 prefectures. Renewal of the website including the soil page. The soil project led to the addition of new measuring rooms, and more than 30.

April-June 2015 Implemented the first round of funding by crowdfunding

Implemented to obtain funds for soil project activities. Achieved 2,100,000 yen. Travel expenses to hold workshops in various places, will be used to cover the measurement costs.

June 2015 Takagi Jinsaburo Citizen Science Foundation graduated from co-representative

Takagi Jinsaburo Citizen Science Foundation, which was one of the co-representatives, achieved the purpose of launching the project.

November 2015 Held a briefing session on the East Japan Soil Becquerel Measurement Project

Held a briefing session on the East Japan Soil Becquerel Measurement Project. We will report on the actual conditions of radioactive contamination that we have seen from soil collection.

March 2016 Conducted event and briefing session Achieved 1,700 soil sampling

While telling what has been seen from the map, we continue to request soil collection cooperation for the blank area.

November 2016 to January 2017 Implementing the second round of funding by Crowdfunding

2,350,000 yen achieved. Used to advance the collection of blank areas. In addition, we have funds for system development.

January 31, 2017 Soil beckerel measurement project free measurement period end

By this time, more than 3,000 measurement points have been collected. For areas that are left blank, the Secretariat will collect and measure.

March 2017 "Thank you 3,000! Soil project briefing session" held

Create maps based on more than 3,000 measurement data. Attenuation correction calculation of the numerical value of the map was carried out, and "the 100 year map" which can predict from the time of 2011 to 100 years later was shown. In search of cooperation of groups facing radiation contamination, 11 groups opened a booth, and more than 160 people including general participants became a meeting place all together. We introduced members of the measuring room of the whole country and did trial sale of paper maps.

March 2017 Launch of "Environmental Concentration Becquer Measurement Project"

Start a project to draw attention to so-called "hot spots" where cesium is concentrated in the environment not by standard soil contamination but by the flow of water, etc.

November 2017 Website Renewal Implemented

Renewal aimed at an easy-to-understand website. Participating measurement rooms will be 34 measurement rooms throughout the country. Not only can search and view the measurement results of food and soil projects, but also renews the concept based on the addition of commentary for easy understanding. A page was opened to advance analysis of the data accumulated so far.
