学校周辺の除染活動

昼の除染の報告です。丸一日かけて学校西側の難敵ゴムチップ歩道とやや難敵木道を除染しました。

実はPTAとしての除染活動は昨日の雪で延期にしていましたのですが、今回は市内の恵和興業さんがお忙しい日程の中、新しいマシンの試運転をかねてと言うことでボランティアでお手伝い頂けることとなっていたので朝から積もった雪を除雪して実施しました。

技術指導をされた日環研さんと恵和興業さんのお力をお借りしてゴムチップ歩道で約３割減、木道で約５割減でした。普通のコンクリ面とかだと７割くらいは落ちるそうです。仕組みは基本的には超高圧の温水洗浄ですが、それと吸引を同時に行うのがポイント。吸い上げた汚水は回収し、放射性物質を含んだ泥と水分を分離します。基本的に歩道なので特に土がある訳ではないのですが、一日の作業で実に土嚢袋で８袋くらいの泥が出ました。

地域除染活動への補助金は来年度も継続されます。私達の出来る除染活動も限界のある所もあるので来年度は私達の出来るところはコツコツやりながら、追加の補助金を利用してこうしたプロに委託するのも手ではないかと思います。

今回ご協力頂いた作業はざっくり500円/平方メートル程度とのこと。表面の違いによる難易度や作業時間等で違ってくるとのこと。コンクリ面であれば一日で７００平方メートル程度作業出来るとのことです。PTA等で学校のまわりで場所を決めてやるのには良いかもしれません。ちなみに詳細の線量の測定もお願いするとするとそれはまた別途相談とのこと。

今後、PTAでも作業を継続して行ってゆく予定です。

皆様、本当に有り難うございました。

Monitoring Posts

368 monitoring posts are currently working in Fukushima city and monitor environmental radioactivity level 24h/365days . Most of them sit on school-grounds where children spend most of time on weekdays. Realtime data can be checked through MEXT's web page.

Fukushima city completed decontamination work of schools in 3Q last year to minimise influences to children as first priority. This indeed contributes to improve the level in side the school premises. However, radiation influences from outside of the school given a facts gamma-ray travels around 70m. It is urged to accelerate decontamination works around schools. Difficulties to set temporally storage stations of decontamination work residuals, radioactive wastes delays, areal cleanup work. Only limited area could reach an agreement to set such storage spaces so far.

I will report decontamination work efforts by communities separately.

ICPR post-accident dialogue seminor in Fukuhsima

ICRP's 2nd post accident dialogue seminor was held in Fukushima having various stakeholders attended. One of conclusions enphasised an importance to human dimention of the situation. That is, there should be arguments beyond scientific agument. What is value to the region? There is a way to accept risk to take larger benefits based on such value. ICRP specialists see imposed regulations in Japan is safe enough and may become to strict in view of such value of the region.

But it is also true that to convince safety and to make feel safe is largely different to residents in Fukushima.

Thank you for visiting my page

It has been almost a year since the disaster hit Tohoku area including Fukushima. At this opprtunity, I would like to thank you for your all supports provided to the region from all over the world.

I'm living in Fukushima city where is approx. 60km far to northwest from the NPP. As you all know, due to followed explosion of the NPP, even the city area is affected by rather high radiation contaminations.

You may have read news about the region maybe mainly from the negative side; however, it is true that people in Fukushima is making possible efforts to recover the situation believing our future.

I would like to share our messages from Fukushima; what is going on? how we look at the situation? what we would like you to understand.

I will try to update as often as possible when time allows. Any queations/comments for both of us to move forward are welcome.

Sincerely,
