In addition, it is called "Das Erste" of the name shortened in fact.
It is Fukushima's butterfly and is teratogenesis.
Unusual to a butterfly at a nuclear power plant disaster University of the Ryukyus team investigation http://www -- under the influence of the radioactive material by .47news.jp/47 topics/e / the 1st nuclear power plant disaster of 233375.php Tokyo Electric Power Fukushima, The research team of Associate Professor Joji Otaki (molecular physiology) of University of the Ryukyus summarized the results of an investigation it is supposed that hereditary abnormalities appeared in a kind "Yamato freshwater clam" of the butterfly, and it published in the English science journal electronic edition it by 10/10/2012.
Many Yamato freshwater clams at the place where people live.
The team collected Ibaraki besides an Fukushima within the prefecture, Tokyo, etc. at a total of ten places in May, last year and September.
When the egg produced from 144 imagos collected in May was hatched, it raised and even the grandchild's generation investigated, butterflies Fukushima within the prefecture, such as Hirono-cho, Iwaki, had the high probability of dying from a child's generation, compared with other areas.
The size of male feather of the area where a dose is higher was small.
In a child's generation, there were abnormalities in the color scheme pattern of feather, the number of spots, etc. at about twenty percent of the whole, and it was 1.5 times as high generating frequency as parents' generation.
With about 240 imagos collected in September, abnormalities were found at about 50 percent of the child's generations.
The same abnormalities came out in the experiment which the Yamato freshwater clam of Okinawa expected for there to be almost no influence of the radioactive material in an accident was made to make contamination of a low dose.
Mr. Otaki "although it was said that an insect was strong in the radiation of a low dose, it turned out that the Yamato freshwater clam is weak.
It is being said that it is certain that the accident has affected surrounding nature."

福島のチョウで奇形発生.
原発事故でチョウに異常 琉球大チーム調査
http://www.47news.jp/47topics/e/233375.php
東京電力福島第１原発事故による放射性物質の影響で、チョウの一種「ヤマトシジミ」に遺伝的な異常が出たとする調査結果を琉球大の大瀧丈二准教授（分子生理学）らの研究チームがまとめ、10/10/2012 までに英科学誌電子版に発表した。
ヤマトシジミは人が生活する場所に多く生息する。チームは昨年５月と９月、福島県内のほか茨城、東京など計１０カ所で採集した。
５月に集めた成虫１４４匹から生まれた卵をふ化させて育て、孫の世代まで調べたところ、いわき市や広野町など福島県内のチョウは、子の世代で死ぬ確率がほかの地域に比べ高かった。線量が高い地域ほどオスの羽のサイズが小さくなっていた。子の世代では全体の約２割で羽の配色パターンや斑点の数などに異常があり、親の世代よりも１・５倍高い発生頻度だった。
９月に採集した成虫約２４０匹では、子の世代の約５割で異常が見つかった。
事故による放射性物質の影響がほとんどないとみられる沖縄のヤマトシジミに低線量の被ばくをさせた実験では、同様の異常が出た。
大瀧さんは「昆虫は低線量の放射線に強いと言われていたが、ヤマトシジミは弱いことが分かった。事故が周辺の自然に影響を与えているのは間違いない」と話している。

Mr. bob_arikui
The direction where the external skeleton is solid is considered to be strong in radiation to be sure.
However, it is a thing with famous radiation resistivity at an insect.
It is in the dry state of the larva of bear or a sleep chironomid.
It is said that it cannot be alive if man is exposed to the radiation for which it exceeds 6 Gy, but, as for larva of bear , the individual which even 9000-Gy radiation survives needs 5000 Gy and a sleep chironomid.
Since DNA repair capability is high about why it has high tolerance in radiation in this way, the living thing vitrification by trehalose, etc. are said, but it does not yet understand well.
Incidentally
Probably, there is nothing "for which a cockroach takes a world after man."
Since there is a living thing in which ability of reproduction is higher than a cockroach without limit and a cockroach is eaten by a spider, bird, etc. above all, it is thought that a number of individuals cannot be increased to there.
* Note2. Unit of radiation (source: Ministry of Education, Culture, Sports, Science and Technology)
How does a sievert (Sv) differ from gray (Gy)?
The unit of Gy is a unit showing a physical quantity, and it expresses [ "of which grade energy was given to the human body by radiation", and ] it, for example.
However, even if the same energy (dose) is given, it is known that the influence which it has on a living thing according to the kind of radiation will change.
Since it supplements with this, Sv is used.
Constant xGy of the living thing effect by the kind of Sv= radiation
It is come out and expressed.
Therefore, when Sv argues about the influence of contaminated, it is used, and the present Laws Concerning the Prevention from Radiation Hazards due to Radioisotopes and Others are also based on this quantity.
For this reason, while Gy is called the unit of physical quantity, Sv is called the unit of the amount of protection.
If this constant is 1 and becomes neutron ray, a line, a baryon line, etc. to a line or a line, it will take the value of 5-20.
Therefore, like the accident of JCO, except for a special example, since X-rays and the line are main, the usual contamination may treat with Gy=Sv.

外骨格がしっかりしている方が確かに放射線には強いと思われます。
しかし、昆虫で放射線耐性が有名なのは
クマムシやネムリユスリカの幼虫の乾燥状態です。
人間は6Gyを超える放射線を浴びると生きてはいられませんが、
クマムシは5000Gy、ネムリユスリカは9000Ｇｙの放射線でも
生き残る個体がいるそうです。
なぜこのように放射線に高い耐性を持っているかについては
ＤＮＡ修復能力が高いためや、トレハロースによる生物ガラス化など
言われていますが、未だによくわかっていません。
ちなみに
『ゴキブリが人間の後に天下を取る』
なんてことはないでしょう。
ゴキブリより繁殖能力が高い生物はいくらでもいますし、
なによりゴキブリはクモや鳥などに食べられますので、
そこまで個体数を増やすことはできないと考えられます。
☆Note2. 放射線の単位 (出典：文部科学省)
グレイ(Gy)とシーベルト(Sv)はどう違うのでしょうか？
Gyという単位は、物理的な量を表す単位で、例えば「人体に放射線によりどの位のエネルギーが与えられたか」を表します。しかしながら同じエネルギー(線量)が与えられても放射線の種類によって生物に与える影響が変わることが知られています。これを補足するために、Svが使われます。
Sv＝放射線の種類による生物効果の定数×Gy
で表されます。したがって、Svは被曝の影響を議論する際に使われ、現在の放射線障害防止法もこの量に基づいています。このためGyが物理量の単位と呼ばれるのに対し、Svは防護量の単位と呼ばれています。この定数は線や線に対しては1で、中性子線、線、重粒子線などになると5から20の値をとります。したがって、JCOの事故のように特殊な例を除いて、通常の被曝はX線、線が主ですのでGy=Svと扱ってかまわないことになります。
