Ibaraki local gov rebelled against JP gov about fishery product safety limit
Posted by Mochizuki on March 14th, 2012 · No Comments
Ibaraki local government and Ibaraki fisherman’s union will ban shipping fishery products which they measured more than 50 Bq/kg after April.
Currently, Japanese government set the safety limit of fishery products to be 500Bq/kg. After April, it will be decreased to be 100 Bq/Kg. However, Ibaraki local government will apply more strict safety limit to appeal the safety of their products.
They have already measured more than 50 Bq/Kg from their products. This will be a challenge for them.

However, it is not announced what kind of nuclides they are going to check.
５０ベクレル超の魚介、出荷自粛へ 放射性物質検査 茨城

■県と漁協が独自基準
県と県内漁業組合団体が県内で取った魚介類について、４月以降、放射性物質検査で１キロ当たり５０ベクレルを超えた場合、出荷を自粛する方向で最終調整していることが１４日分かった。１５日にも発表する。国より厳しい基準を設けることで、「茨城の魚介類は安心・安全」とアピールする狙いがある。
４月以降、魚介類を含む一般食品の放射性セシウムの暫定基準値が、これまでの１キロ当たり５００ベクレルから同１００ベクレルとなる。県内の主要漁協による「茨城沿海地区漁業協同組合連合会」は１４日、水戸市内で会合を開き、「魚介類の安心・安全を打ち出すことが大事」（関係者）と同５０ベクレルを超えた魚介類は出荷自粛の方向で話をまとめたという。
原発事故後、県による放射性物質の検査結果で、５０ベクレルを上回る魚種は複数存在し、漁業関係者らには厳しい“ハードル”を課す形になる。会合に出席した漁業関係者からは「今はシラスなどの小魚が厳しいが、次はヒラメなど底魚が厳しくなるかもしれない」といった声もあがっている。

A Fukushima citizen proved monitoring post was manipulated

Following up this article..Monitoring post manipulated
Mr. Ito Nobuyoshi, a Fukushima farmer compared the radiation level of a monitoring post to the one of a different place, and found a recognizable gap of the radiation level.
Because those 2 places are only 5 m away from each other, this proves the monitoring post was “decontaminated” to make the radiation level look lower than actual at least in Iidate mura.
<Translation>
Today I measured the sand underneath the monitoring post of MEXT with a gamma ray survey meter. It was 0.6μSv/h.
<End>
<Translate>
Measured radiation level at the place where is only 5m away from the monitoring post. On the ground, it was 5.52 μSv/h (↑920%), at 1m above the ground, it was 1.19 μSv/h (↑198%). Now it’s clear that MEXT changed the sand around the monitoring post. Why do they do such a thing ? They are fooling us.
<End>
<Translate>
There is a map sculpted on the stone in front of a community hall. It was 3.40 μSv/h.
<End>
<Translate>
On the root of a tree nearby, it was 15.4 μSv/h.
<End>
<Translate>
This is the parking lot in front of the community hall after “decontamination”. It was 15.3 μSv/h. It’s been where they put contaminated soil from decontamination temporarily. The parking lot for police cars nearby was 8.02 μSv/h, which is about half of the 15.3, but still it’s high. Decontamination is proven to be meaningless.

Fall-out is increasing in Fukushima again
Posted by Mochizuki on March 14th, 2012 · No Comments
Fall-out level in Fukushima has started increasing again.
It has been under 10 MBq/Km2 or ND, but on 3/12/2012, it became as double as before.
3/11/2012 9:00 ~ 3/12/2012 9:00
Cesium 134 : 9.95 MBq/km2
Cesium 137 : 17.8 MBq/km2
3/12/2012 9:00 ~ 3/13/2012 9:00
Cesium 134 : 20.0 MBq/km2 (↑210%)
Cesium 137 : 29.8 MBq/km2 (↑167%)

Radioactive Materials in Soil May Already Have Reached 30 Centimeters Below Surface, JAEA Says
Japan Atomic Energy Agency's researchers say radioactive materials that remained on the top 5 centimeters of the soil for the first 3 months of the nuclear accident may have already migrated down to as deep as 30 centimeters.
It may be difficult to decontaminate, says the agency who happens to be in charge of the government pilot project to decontaminate within the no-entry zone and planned evacuation zone in Fukushima, using joint ventures by the largest construction companies in Japan. (For more on the confused state of this pilot program, see my post on NY Times article.)
But on the other hand, it's been too late anyway in Fukushima, Miyagi, and areas in Kanto with significant amounts of radioactive fallout (except for Miyagi, whose data is still not disclosed, if it exist), where farmers tilled the land in spring last year to grow vegetables and rice upon encouragement from the government.

地中３０センチにまで浸透か 放射性物質、除染に影響も
Radioactive materials may have migrated to 30 centimeter deep in the soil, may affect decontamination efforts
東京電力福島第１原発事故で放出され地面に降り積もった放射性物質について、事故から３カ月後の昨年６月にはほとんどが地表から５センチまでの浅い場所にとどまっていたが、１年後の現在では１０～３０センチの深さまで浸透している可能性があるとの推定を、日本原子力研究開発機構のチームが１４日までにまとめた。
Radioactive materials deposited on the ground after the Fukushima I Nuclear Power Plant accident stayed within 5 centimeters from the soil surface in June last year, 3 months after the accident started, says a research team at Japan Atomic Energy Agency. However, the group says there is a possibility that radioactive materials have now migrated to between 10 and 30 centimeters from the surface, one year after the accident. 雨水がしみ込む際に一緒に運ばれるとみられる。同機構幌延深地層研究ユニット（北海道幌延町）の佐藤治夫研究員は「除染活動が遅れるほど放射性物質は深く移動し、作業の負担を大きくする恐れがある」と警告している。
The team thinks rainwater carries radioactive materials down the soil. Haruo Sato, a researcher in the Horonobe Underground Research Center of JAEA (in Horonobe-cho in Hokkaido) warns, "The longer decontamination takes, the deeper radioactive materials migrate, making the decontamination effort more difficult."Oops... The government and many researchers have said that radioactive materials remain on the shallow surface of the soil, citing the case of Chernobyl. I guess they didn't realize the warm, rainy climate of Japan was different from Chernobyl. The annual average rainfall in Fukushima is 1,300 to 1,600 millimeters, whereas in Chernobyl it is 300 millimeters.
Looking at blog posts and tweets from last summer, many in Japan were hoping the large amount of rain that Japan gets would wash away the radioactive materials to the rivers and to the sea quickly. Instead, it drove them down the soil, according to JAEA.
