Katsurao Village contamination map

Katsurao Village: its whereabouts and evacuation/return policy history

In June 2016, the evacuation order applied to Katsurao village after the Fukushima Daiichi Nuclear accident was lifted for 80% of its territory. The northeast part of the village in the vicinity of Namie town is still classed as a ”difficult-to-return” zone, where the annual airborne radiation dose is over 20mSv. The lifting of the evacuation order of this area is not planned.

葛尾村は、2016年6月に80パーセント以上の地域で避難指示が解除になりました。浪江町と隣接する村の北東部に、年間被ばく量が20ミリSvを超えると推計される帰還困難区域が残りますが、解除の予定はありません。

In June 2018, approximately 300 people are living in the village, which is about 20% of the population before the accident. In April 2018, primary and junior high schools opened where 18 children are currently studying, whereas in 2010, before the accident, 112 children were attending schools.

2018年6月現在の居住者は300人ほどで、事故前の20パーセント程度です。2018年4月には、小中学校が村内で再開され、合計18名が通学しています。事故前(2010年)は、112名でした。

The village is covered by hilly forests as you can see in the Google Earth below.

Should the public be allowed to see the radio-contamination map ?

We are publishing the most recent map of the soil contamination made by the “Fukuichi area environmental radiation monitoring project“.

We have published several soil contamination maps of the “Fukuichi area environmental radiation monitoring project” in this blog (see maps of Namie, Minamisoma 1 & 2 ). Normally, the government should carry out the measurements, but the government relies on the air radiation dose measurements at the expense of the radio-contamination measurements found on the surface and in the air (in terms of the volume of radioactive substances). To fulfill the lack of this essential information for the radioprotection of the population, civil groups conduct soil measurements.

このブログで紹介してきた「ふくいち周辺環境放射線モニタリングプロジェクト」の土壌汚染マップですが(浪江町南相馬市 1 & 2 )、もともと国や地方自治体が実施すべき測定です。しかし、政府は空間線量率の測定のみを優先し、表面(土壌を含む)や空間の汚染密度をニグレクトしています。そのため住民の放射線防護に不可欠の情報が欠如しています。この情報不備を補完するため、市民団体が測定を 実行しているのが現状です。

The scandalous deficiency of the health scheme in Fukushima

Taro Yamamoto of the Liberal Party, member of the House of Councilors, accused the double standard of the the public radioprotection policy during his questions at the Special Commission of Reconstruction of the House of Deputies on March 21, 2017. He compared the health examination scheme introduced by Ibaraki prefecture to its population after the JCO* criticality accident to that currently available to Fukushima residents. The result shows the utter deficiency of the latter in spite of the fact that the Fukushima accident is classified as level 7, much more severe than the JCO level 4 accident.

2017年3月21日、復興特別委員会における質問で山本太郎議員が原子力関係の事故後の健康診断の提供につき、JCO*東海事業所の臨界事故後の茨城県の対応と東電福島事故後の国と福島県の対応を比較、あまりに違うダブルスタンダード、東電福島事故後の国と福島県が県民に提供する健康検診のメニューの貧しさを激しく追求しました。しかも、レベル4のJCO東海臨界事故よりも3レベルも高い、レベル7の事故であるにもかかわらず、です。

We are publishing here the transcription of Taro Yamamoto’s questions** as well as the soil contamination map of Kashima and Haramachi districts of Minamisoma where the evacuation order was lifted in July 2016. The map is provided by the civil measurement group called “Fukuichi*** Area Environmental Radiation Monitoring Project”**** composed mainly of residents of Minamisoma which has been taking measurements of soil contamination in the vicinity of the members’ neighborhoods and in residential areas since 2012. Taro Yamamoto has already used their maps during another session of the Special Commission of Reconstruction. Let us note that in the map uploaded here, there are only two rectangles where the contamination density is lower than 40,000Bq/m2, and that for the rest of Kashima and Haramachi districts, the density is amazingly higher. As Taro Yamamoto indicated during his questions on November 18 last year, according to the Ordinance on Prevention of Ionizing Radiation Hazards a zone is called a Radiation Control Zone when the surface density is over 40,000Bq/m2. In a Radiation Control Zone, following the Ordinance, it is prohibited to drink, eat or stay overnight. Even adults are not allowed to stay more than 10 hours. To leave the zone, one has to go through a strict screening. The map shows that most of the two districts of Minamisoma city are in this situation. But it is not classified as Radiation Control Zone. On the contrary, people are told to go back there to live, including children.

ここで、山本太郎議員の質問の文字起こし**とともに、「ふくいち***周辺環境放射線モニタリングプロジェクト****」の作成した、南相馬市、鹿島区、原町区の土壌汚染地図をアップいたします。このグループは南相馬にお住まいの住民の方々を中心に、2012年からそれぞれの近所、生活圏の土壌汚染などの計測を続けるグループで、以前にも山本太郎議員が2016年11月18日の復興委員会での質問で当グループ作成の地図を資料として使っています。この時の質問で山本議員が指摘したように、電離放射線障害防止規則により、放射性物質の表面密度が40000Bq/m2以上の区域は放射線管理区域と呼びます放射線管理区域では 飲食は禁止、当然寝泊まりはできません。成人でも10時間以上の滞在は許されません。そこから出るときは厳格なスクリーニングを受けなければなりません。地図を見ると、40,000ベクレルよりも低く測定されたところは2箇所にすぎず、他の地域では放射線管理区域の下限をはるかに超える汚染を示しています。しかし、この区域は放射線管理区域に指定されていません。それどころか、このような区域の避難指示がすでに解除され、子供も含む住民の帰還が進められています。

Incredible contamination in Namie, Fukushima

The evacuation orders of the most populated areas of Namie, Fukushima were lifted on March 31st this year.

“Fukuichi area environmental radiation monitoring project” has published airborne radiation measurements map and soil surface density map. The results are simply incredible. This is far much worse than in Radiation Control Zone. Any area becomes designated as such when the total effective dose due to external radiation and that due to radioactive substances in the air is likely to exceed 1.3mSv per quarter – over a period of three months, or when the surface density is over 40,000Bq/m2. In the Radiation Control Zone, it is prohibited to drink, eat or stay overnight. Even adults are not allowed to stay more than 10 hours. To leave the zone, one has to go through a strict screening.

Namie’s radio contamination is far over these figures! And people are told to go back to these areas.

福島県浪江町の人口集中地域の避難指示が3月31日に解除されました。
主として南相馬市に在住の市民の皆さんが作っておられる団体「ふくいち周辺環境放射線モニタリング・プロジェクト」が浪江町の空間線量マップと土壌汚染マップをアップされました。結果は驚くべきものです。外部放射線による実効線量と空気中の放射性物質による実効線量との合計が三月間につき一・三ミリシーベルトを超えるおそれのある区域、または土壌の表面密度が4万ベクレルを超えると、放射線管理区域に指定され、成人でも10時間以上は滞在できず、飲食もできず、宿泊もできません。そこから出るときには厳しいスクリーニングを受けなければなりません。地図を見ると、浪江町の状態は放射線管理区域をはるかに超える汚染の状態です。

浪江町の汚染はこの数値をはるかに超えるものです。そして、こんなところに住民の皆さんは帰れと言われているのです。

Here is the posting of “Fukuichi area environmental radiation monitoring project” in their FB page on April 20th.

以下、「ふくいち周辺環境放射線モニタリング・プロジェクト」の投稿です。

第38回モニタリング活動で測定した浪江町の避難解除地域のギョロガイガーによる地上高1mの空間線量マップが完成しましたので、UPします。
100箇所のポイントのうち、1μSv/hオーバーは実に56ポイントありました。マップでは1μSv/hオーバーを赤枠で囲みましたが、最高は3.71μSv/hでした。
なんとこの数字は、1年間に換算すると32mSvにもなります。こんなところに、被災者を帰還させて良いのでしょうか?

We are uploading the map of airborne radiation rate map measured by GyoroGeiger, the Android supported Geiger counter, during the 38th monitoring action between 3 and 7 April 2017. Dose rate is measured at 1m from the ground.
At 56 points over 100 measuring points, the dose rate was over 1µSv/h. These points are indicated in red. The highest measure was 3.71µSv/h. Conversion to annual dose gives 32mSv. Is it allowed to make evacuees return to such areas?

Here is the soil contamination map uploaded on April 15th. They even had to introduce 7 scales, for the contamination is so high and they couldn’t deal with the scales they were using before! It is a violation of human rights to let people live in such areas.

Taro YAMAMOTO

電離放射線障害防止規則、電離則というものがあるのは皆さん御存じのとおり。これは病院や研究施設、原子力発電所などで働く放射線業務従事者の皆さんを守るための規則ですよね。

You are well aware of the existence of the Ordinance on Prevention of Ionizing Radiation Hazards. This is a rule that must be respected in order to protect workers exposed to risks related to ionizing radiation in establishments such as hospitals, research laboratories and nuclear power plants, isn’t it?

資料の一、電離則の第三条には管理区域、つまり放射線管理区域を定める内容が書かれている。三条の一、二、どっちかに該当したら管理区域ということで標識も立てなさいよ、そのように書かれている。その一と二を私が読んでみたいと思います。

It contains the definition of the Radiation Control Zone. This is Article 3 of the Ordinance in File No. 1. It states that if the situation corresponds to the definition described in Article 3/1 or to that specified in Article 3/2, the zone shall be considered as a Radiation Control Zone and a sign must be posted there. I will read parts 1 and 2 of this article.

一、外部放射線による実効線量と空気中の放射性物質による実効線量との合計が三月間、三か月ですね、三月間につき一・三ミリシーベルトを超えるおそれのある区域。二、放射性物質の表面密度が別表第三に掲げる限度の十分の一を超えるおそれのある区域。三か月で一・三ミリシーベルトの線量で放射線管理区域と呼ぶそうです。

1: The area in which the total effective dose due to external radiation and that due to radioactive substances in the air is likely to exceed 1.3mSv per quarter – over a period of three months! When the dose reaches 1.3mSv over a period of three months, a zone is called a Radiation Control Zone.

そして、三条の二に出てきた表面密度は別表でとありました。
資料の二です。ここで言う表面密度を平方メートルで換算すると幾らになるでしょうか。

Part 3/2 refers to the surface density in the attached table.
Here is File No. 2. What will it be if we do the conversion of the density of the surface per m2?

○政府参考人(田中誠二) 一平方メートル当たりで計算いたしますと、四万ベクレルとなります。

○ Government expert (Seiji Tanaka)
The conversion is 40,000Bq/m2

(略)

(…..)

福島県の浜通り、南相馬市、震災以降三種類の避難区域に指定、今年七月には避難指示解除準備区域と居住制限区域が解除され、現在は一世帯二人が該当する帰還困難区域のみが残っています。南相馬の九割以上が国が言うところの大丈夫な地域だそうです。南相馬にお住まいの住民の方々を中心に、二〇一二年からそれぞれの近所、生活圏の土壌汚染などの計測を続けるグループ、ふくいち周辺環境放射線モニタリングプロジェクト、その方々からの情報提供が資料の三でございます。色の付いた地図が御覧いただけます。

これは、除染が終わった地域の土を採取、計測したもので、汚染度に応じて色分けがされています。一平方メートル当たり四万ベクレルの放射線管理区域相当を下回る場所が青色です。右の下の方にありますかね、一つだけ確認できますよね。それ以外は管理区域相当かそれ以上、百万ベクレルに値する灰色の地域まである。これ、人住んでいるんですよね。

In the town of Minamisoma in the coastal region of Fukushima Prefecture, three types of evacuation zones were established after the earthquake. In July 2016, the evacuation order was lifted in the “evacuation order lifting preparation area” and in the ‘’not-permitted-to-live area’’. There is only one household with two people remaining in the “the difficult-to-return-to area”.
According to the State, 90% of the territories of Minamisoma are safe.

There is a group called “The Fukuichi Area Environmental Radiation Monitoring Project*** ” composed mainly of residents of Minamisoma. Since 2012, its members have been taking measurements of soil contamination in the vicinity of the members’ neighborhoods and in residential areas. They provided the information. Please take a look at File No. 3. You see a colored map.

This is the map of soil collected and measured in the territories where the decontamination works have been completed. The colors show the levels of contamination. The blue colored area indicates where the contamination measurements are below 40,000Bq / m2, ie below the level of a radioactivity controlled zone. There is only one, at the bottom right. Apart from this one, at all other places, the colors show measurements equivalent or higher than in a Radiation Control Zone. There is even an area colored gray where the measurements exceed 1,000,000Bq / m2. There are people living there!

すでに避難指示が解除された南相馬市小高区、汚染は終了しているという建前です。しかし2つの土壌マップを見ると、殆どの地域が放射線管理区域の下限の汚染度をはるかに上回る汚染を示しています。

The evacuation order is already lifted from Odaka district of Minamisoma town, and officially the decontamination work has finished. However, the two maps show that in wide areas highly radioactive soil is being found. Their measurements are well above the lower contamination limit of a Radiation Control Zone.

放射線管理区域では電離放射線障害防止規則により、 飲食は禁止、当然寝泊まりはできません。成人でも10時間以上の滞在は許されません。そこから出るときは厳格なスクリーニングを受けなければなりません。

In a Radiation Control Zone, following the Ordinance on Prevention of Ionizing Radiation Hazards, it is prohibited to drink, eat or stay overnight. Even adults are not allowed to stay more than 10 hours. To leave the zone, one has to go through a strict screening.

そんなところに人が住めるのでしょうか?

How can people live there?

放射能管理区域よりひどい汚染地帯に帰還させる、避難を続ける人には支援を打ち切り、という政策は基本的人権に抵触するものです。

The policy to make a population return and live in areas even more contaminated than most of the Radiation Control Zone, while cutting the financial and housing aid for evacuees, is a serious infringement of human rights.
