2017 Fall Soil Project Briefing Report

2017 Fall Soil Project Briefing Report

We held a briefing session at the National Olympics Memorial Youth Center on a sunny Sunday.

We were able to welcome a large number of customers early in the morning. Thank you very much.

As a blueprint of the compilation "map collection, atlas version" (cesium atlas version) of "East Japan soil beckerel measurement project" that is currently planned to be produced, taking two cases of Tochigi and Yamagata as an example, the measurement results Three speakers reported focusing on introducing examples that have been seen by overlaying various data.

We will briefly report the contents of the day.

■ Introduction of participating measurement rooms

Everybody's data site consists of 34 measurement rooms nationwide. By measuring the food and soil brought in by the local community in each measuring room, measuring what you care about yourself, and registering the data in the common database of "all people's data site" This is a mechanism that allows many people to see the results on the Internet.

On the day, we had everyone in the measuring room gathered from all over the country come up on the platform, and it was a little time, but we said hello while looking at faces such as "I think you are continuing to measure".

Message from the measuring room of the whole country (the measuring room of Hiroshima participates from the north from Hokkaido to the south)

■ What has been seen from "Soil map" and "radioactive substance inspection data in food" implemented by local governments-Analysis report focusing on Yamagata Prefecture (directly from Agano's lab / Murakami)

Yamagata Prefecture is relatively adjacent to Fukushima Prefecture with relatively low levels of radioactivity. Murakami of the laboratory of the laboratory reported the analysis result about the reason and the correlation with food.
From the topography such as the mountains and the weather at that time (snow conditions), we speculated on where and why the radioactivity was established. In addition, based on the results of food inspection conducted by the local government, we have compared the soil maps with municipalities with shipment restrictions and over the standard value (100 Bq / kg or more) for wild animals (Japanese black bear, deer, wild boar etc).

In areas where cesium concentration is high, there was an introduction such as that the number of measurements of Asiatic black bears was extremely small, and that in some areas where Matagi culture remained, the shipping restrictions were lifted on condition of full head inspection.

Among wild plants (such as kosia bra, wild mushrooms and bamboo shoots), those exceeding standard values are scattered near prefectural border near the mountain, and even in Yamagata prefecture where cesium concentration is considered to be low, wildlife and wild plants and vegetables With regard to mushrooms, caution is required because high cesium exceeding the standard value is detected. It is important to note that shipping restrictions apply only to the products sold, and so do not include self-consumption.

In classification consideration of food data which the local government measured, we compare Yamagata prefecture, Niigata prefecture, Tochigi prefecture, Kanagawa prefecture etc. and thing that there are notably in Yamagata prefecture is that prefecture special product (beef, cherry etc) Introduced.
Consider cesium deposition results from the topography of Yamagata Prefecture and snowfall information at that time

Commentary on the impact of 20 millisieverts
According to the standards of the Chernobyl Act established in Russia after the Chernobyl accident, Tochigi Prefecture has multiple areas that fall under the “migration obligation zone” and “migration right zone”, and it is currently the Japanese standard “20 It is safe if the exposure of 20 millisieverts per year will last for a long time, even with ICRP Vice-chairman Jack Rochard, “Sorry,” “I can not understand,” “Not safe,” “How severe is the standard,“ Millisievert ”? "I did not say that."

He also introduced the simulation of iodine flow at that time and the iodine measurement value of tap water, and warned of the possibility of initial exposure.

With boars, wild mushrooms and wild vegetables, you also need to be careful about ashes such as wood burning stoves. At Chernobyl eight to ten years after the accident, the difference in eating habits with the Russian people is that the internal exposure value is even greater than immediately after the accident, and the half life of cesium-137 is thirty years. He warned that there would be a risk of increasing internal exposure, like Chernobyl, if he thought that "almost all right" was eaten, taking as an example mushrooms picking in a region rich in mountain confections and preference for jibe as an example in Japan.

Changes in internal cesium exposure to adult cesium in multiple regions in Ukraine (1986-2008)

Changes in internal exposure in three villages such as Kiev (red for adults and green for children)

The Tooth Tooth Preservation Network is the first private sector dedicated strontium tooth measurement station where C-Lab also participates, and is currently being prepared for establishment in Gifu Prefecture. At the venue, a kit for collecting and sending milk teeth was distributed, and all the prepared kits were exhausted. We are also looking for investors to set up a measuring station.

■ Introduction of “Environmental Concentration Becquer Measurement Project” and request for crowdfunding (Hotspot Investigators for Truth (HIT) Representative Sugar Nat)

The so-called micro-hotspot, HIT has been steadily carrying out activities to discover and measure places where radioactive materials have accumulated significantly compared with the surrounding area, and to ask the government for measures such as decontamination. Hot spots are within a limited range, so removing them can eliminate the danger. However, according to the current standards of the Ministry of the Environment, a wide range such as characters and towns is regarded as one unit, and the decontamination standard is determined by the average air dose (mainly 1 meter in height). Contamination has been virtually abandoned.

At a height of 1 meter, 0.451 μSv / h, and when measured at a height of 5 cm, 2.682 μSv / h, etc.
If only one meter is measured, very high pollution will be abandoned.

Based on the current situation, we are working to protect people from radiation exposure, such as parks that are familiar to children and street sidewalks where people come and go, and bicycle parking lots.

In fact, we introduced examples of what kind of contamination there was and how much the air dose dropped after having been decontaminated by the local government after the notification.

In order to make this activity widely known, patterns of places where it is likely to become a hot spot are displayed in an easy-to-understand manner with illustrations of 12 categories such as rain gutters, snowdrifts, tree roots, buildings kiwa etc. The project is being carried out jointly with everyone's data site by posting it on the web under the title "Environmental Concentration Becquerol Measurement Project".

● Everybody's data site Environmental concentration Becquerel measurement project https://minnanods.net/soil#soil-soil-top-hotspot12-head

We show place which is easy to become hotspot by 12 classification by illustration,
We publish measurement value of each type of measurement point

He also pointed out that these activities are most likely to move the administration if requested by the citizens who actually live in the local government.
In the nuclear accident, the local government is also the same victim as our citizens. From that point of view, I will teach you the tips that it is easy to work if you can build a good relationship with the administration.
If you say, "I do not know where the hotspot is" or "I do not know the negotiations with the local government", I will go out, so let's all be connected. And called.

In order to continue this activity, we are raising funds through crowdfunding until December 25th. Thank you for your cooperation.

(Congratulations) [Announcement of Kazuo Hisumi, Information Sharing Promotion Fund]

The data site of everyone was selected for the "Age of Information Sharing Promotion Fund" Grand Prize announced today on November 13.
We would like to report on the award of the very prestigious Hissumi Award, which we are all happy and thankful to all of the staff.

The data site for everyone was launched in 2012, and the citizens and 34 measurement rooms cooperated to accumulate and release radioactive contamination measurement data since the 2011 Tokyo Electric Power Company Fukushima Daiichi Nuclear Power Plant accident.

In our database, nearly 15,000 food products and 3,500 soil data are accumulated by citizenship, and anyone can search and browse on the web.
Each case of food data, many people in general are concerned about your child's health, etc., it is stacked around the data brought into the measurement, each data is valuable. What has come to this form is that it can only be realized by the cooperation with many people.

Also, from 2014, we conducted extensive soil measurements across 17 eastern Japan, under the title of “East Japan soil becquerel measurement project”, collected soil measurements at various locations with over 4,000 people and accumulated data We are working on visualizing the state of pollution.

Soil data, after the Chernobyl accident, large-scale measurements were taken at Ukraine and Belarus at national costs, recorded and released, and used as judgment criteria for evacuation and recreation, but in Japan almost only air dose It has remained in the measurement of Also, the standard of 20mSv per year, which is 20 times as high as the value before the nuclear accident, continues to be adopted, and this is currently used to judge the evacuation and return standards of the residents.
Under such circumstances, with the thought that "you should have the right to know the pollution of the area where you live", "If the government does not do it, let's make it clear by itself" We have endeavored to investigate, record and publish “data of We will continue to work to make this data available to many people for use.

This award, together with a large number of people, including citizens who have requested measurement to measuring stations throughout the country, those who have supported us with funds such as collection activities and campaigns, etc. I think that it was received, I want to be happy together.
I feel great power in showing the actual situation of radioactive contamination by the power of citizen science by accumulating measurement data.

Thank you very much to everyone involved in the Information Sharing Promotion Fund of the corner.
We will further advance this award to make it possible to measure and visualize the scars of the nuclear accident and to contribute to many more people.

Thank you in advance for everyone's data site.

Everyone's data site staff

[Information for the 19th (Sun) soil project briefing session]
This weekend 19th (Sun) AM 9:30 am, there will be a briefing session on everyone's data site soil project.

We will provide information from various angles on the actual condition of soil contamination that is being measured and visualized in 17 eastern Japan prefectures.
We look forward to seeing you there!
With the strength of Mr. Hissumi's award, we will deliver information to all of you as a wonderful event.
Please come on the invitation by all means.

During the crowdfunding of activities to find hot spots and decontaminate and protect children!

On November 4th, crowdfunding of collaboration project "environmental enrichment becquerol measurement project" by group called Hotspot Investigators for Truth (abbreviated HIT) and all data sites started! !
Since the “East Japan Soil Becquerel Measurement Project”, which had been implemented so far, was a project to investigate the average pollution in each area, is it not a hot spot survey? We received a lot of voices.

We have been preparing for a project to investigate and release high concentration contamination points, taking out with HIT for over a year.
The system for posting the measurement results was finally developed from July, and it was about to start releasing it, and it was at the stage of asking everyone to formally request support.
The first purpose is to cooperate with local residents at the spot where the hotspot was found, and to negotiate with the local government to request decontamination and cleaning, and the second purpose is to concentrate easily into a hotspot Visualize topography and trends to reduce the risk of exposure.

I would like to support the expenses of about 550,000 yen by 23:59 on the night of Christmas on December 25, thank you! !
Please support this project that will keep you informed of the fact that it will not cause pollution. !

11/19 · Introduction of contents of Tokyo soil project event: Analysis report of Tochigi and Yamagata soil surveys

We would like to inform you of the content to be reported at the soil project report meeting held on November 19 (Sun).

In the soil project, we conducted soil collection and measurement of over 3,000 points in 17 eastern Japan prefectures with citizens. By analyzing the measurement results and trying to match it with the terrain etc., we will tell you ahead of time what you have seen etc. to everyone.
This time, we will analyze in advance two parts of Tochigi Prefecture, which is one of the priority areas for pollution, and Yamagata Prefecture, which has a relatively low level of pollution, and make it an interim report at this point.

1. Analysis report summary of soil survey in Tochigi prefecture
(Nagoya C-Lab, Mr. Junichi Onuma)

Out of 3300 points in 17 prefectures, we conducted a soil survey at 292 points in Tochigi prefecture where the high concentration was polluted and analyzed it. In Nasu town, it exceeded 23000 Bq / kg and it is a mandatory zone of migration in the Chernobyl method There is one place. There are 21 migration recommended zones exceeding 8500 Bq / kg in Nasu-machi, Nasu-Shiobara-shi and Yaita-shi, and in addition to these 3 local governments, migration exceeds 2800 Bq / kg in Nikko-shi, Shioya-cho, Otawara-shi and Nakagawa-machi There were 81 rights zones in total. Serious initial exposure is also a concern. However, six and a half years have passed without the government or the local government taking appropriate measures. There is concern about the exposure of the citizens, especially children. Even now, it is necessary to take measures like Fukushima, such as health surveys. "

* On the other hand, Mr. Onuma will travel to various locations in Tochigi Prefecture with the results of this report for about a week from the end of October to November, and will hold a briefing session and a measurement workshop. On the day of the event, we will introduce the situation of radioactive contamination in Tochigi prefecture, together with the Tochigi briefing session.

2. Analysis report summary of soil survey in Yamagata Prefecture
(Amoro lab Murakami)

As a result of " MDS East Japan soil becquerel measurement project" by the hand of the citizen, the soil contamination map of 17 eastern Japan prefectures has been enhanced more and more. Though it was thought that there was almost no pollution in Yamagata and Niigata prefectures that are close to and in close proximity to Fukushima Prefecture, the obtained map shows that areas with low contamination levels are widely present in both prefectures.

Analysis of " MDS soil pollution map" and "radioactive substance inspection data in food" conducted by Yamagata Prefecture and buried measurement data, why Yamagata Prefecture escaped from strong pollution, Yamagata Prefecture's original "food inspection after the disaster" "Strategy" has come to light.

Even in areas where pollution on flat land is low, such as Yamagata Prefecture, “mountain pollution” continues as the test data of “Japanese horse mackerel”, “Yanasai (Kosibura)” and “Natural mushroom” continue, and “food standards exceeded” There is no end to the case.

3. Environmental concentration Becquerel measurement project
(Mr. SugarNat)

In the previous soil projects, we did not include measurements of hotspots to determine standard contamination levels in the area. However, micro hotspots (where radioactive materials gather and become highly concentrated) that are present everywhere are a big problem. In cooperation with the Hotspot Investigators for Truth, which has been working on the search, measurement, and decontamination of this hot spot for a long time, it has accumulated the data measured by them on the "everyone's data site" Started to
What points are likely to be hotspots using illustrations etc? It is displayed.
On the day, representative Sugar Nut will introduce the past measurement activities and the results of the government's efforts.

In the future, we plan to publish the results of analyzing more than 3,000 data from the "Soil Project," which we have been working with everyone, in the Atlas "Atlas," which is scheduled to be published in the future.

All themes are stories that can only be heard here.
Please come to the event from 9:30 on Sunday, 19th of November.

Survey on internally exposed milk teeth
First private measuring station in Gifu

  The country's first private measuring station will be launched in Gifu Prefecture by the end of the year by analyzing the milk teeth of children in various regions and examining the effects by examining radioactive materials released during the 2011 Tsurugi Fukushima Daiichi Nuclear Power Plant accident. At the time when the natural teeth of the child born at the time of the accident began to come off naturally, we called out and collected all over the country. Measure the concentration of the accumulated radioactive material Strontium 90 , and start investigation on the possibility of internal exposure and the spread of radioactive contamination. (Ogura Yoshitoshi)

Fukushima accident received children of the whole country
They are managed by Dr. Eisuke Matsui ( 79 ) who opens a clinic in Gifu City, Chihiro Ichihara visiting professor at Aichi Medical University (neutron engineering) and 13 researchers at Nagoya University and Gifu University . Currently, we are in the process of rebuilding the building of a construction company in Gifu City Ayabe Hongo to a measuring station.
Among radioactive substances released in the nuclear accident, strontium is likely to be accumulated in teeth and bones. Such as the through breast milk and food, was established to see that there is a possibility that has been accumulated in the children, Matsui et al., September 15, years, civil society organizations, which call for the provision of entrance examination "baby teeth save network" the (Gifu City). To date, about 300 milk teeth have been collected from around the country.
The establishment of the measuring station requires 25 million yen, including equipment purchase and building repair costs . Furthermore, long-term continuous activities are essential for data collection and analysis. "We need a system that allows a large number of people, regardless of companies, individuals and individuals, to take out funds and participate," (Mr. Ichihara) established in February this year a non-profit corporation "Haha" to handle operations. I raised my capital and bought a US-made crisis that can be measured with high accuracy.
In addition, Matsui et al. 'S five members trained at the state laboratory in Basel, Switzerland, which has a track record in strontium analysis of primary teeth, and learned methods.
The measurement of the milk tooth assumes about 400 people of a wide age and area a year . The applicant notes the place of birth, the place where he / she grew up, the day when he / she lost his teeth, etc. on a predetermined sheet of paper, and sends about 4 small teeth including the front teeth and 1 back tooth. Measurement is free. The results will be informed one by one, and health counseling will be provided.
On the impact on local children, from Fukushima Prefecture Dental Association is Tohoku University, such as the 13 December, measures the intensity of the radiation dose of baby teeth.
Mr. Matsui is calling for cooperation, "If scientific data are gathered, we will ask the national and local governments for extensive research. We will clarify what happened in the accident and protect the future of our children." For inquiries, please go to the Dental Tooth Conservation Network = 058 (296) 4038 .

● strontium 90 half-life of 28.8 years. If it is taken into the body from air or food, it will easily accumulate in bones and teeth, and it may last for several decades and cause health damage such as leukemia.
