Radiation Contamination of Tokyo Bay Already Happening

From Asahi Shinbun (2/8/2012):

東京湾の海底で、放射性セシウムが深さ20センチ以上の泥まで達していることが近畿大の調査でわかった。地上の土壌では5センチ以内に9割以上とどまるが、海底では逆に深い方が濃くなる場所もあった。

A survey by Kinki University has revealed that radioactive cesium has reached the depth of 20 centimeters of the ocean mud in Tokyo Bay. More than 90% of radioactive cesium stays within 5 centimeters from the soil surface on land, but on the ocean floor there are spots where the deeper soil contains more radioactive cesium.

 セシウムを含む海底の泥を食べた生物が、泥の中に排泄(はいせつ)するためとみられる。山崎秀夫教授(環境解析学)は「海洋汚染への影響を考えると、深く埋まるのが早まるのはいいことだ」としている。

It may be because of the feces of the organisms in the mud that eat the mud containing cesium. Professor Hideo Yamazaki (environmental analysis) says, "It is a good thing that radioactive cesium gets buried deep quickly, when we consider the impact on marine contamination."

 山崎教授は昨年8月、東京湾の荒川河口付近の4カ所で海底の泥を掘って調べた結果、放射性セシウムが深さ24~26センチのところでも確認された。別の場所では12~14センチでの濃度が最も高かった。セシウムはいずれも東京電力福島第一原発から出たとみられる。

Professor Yamazaki collected the mud on the ocean floor at 4 location near the mouth of River Arakawa that flows into Tokyo Bay last August. Radioactive cesium was found in the mud 24 to 26 centimeters deep. In other locations, the highest concentration of radioactive cesium was found between 12 to 14 centimeters deep. Cesium is considered to have come from Fukushima I Nuclear Power Plant.

I'm not sure if it's a good thing.

Asahi's article, since the full version is only available to paid subscribers, doesn't mention the density of radioactive cesium. But Professor Yamazaki was featured in the NHK documentary on marine contamination (aired on 1/15/2012), and in that documentary the mud collected from the mouth of Edogawa River was found with 872 becquerels/kg of radioactive cesium. (I'll write about the NHK documentary later.)

.feel good fluff piece
/japan is ded short of GODLY INTERVENTION< ONLY WAY, YOU WILL PROVE IT.
COMMUNISM, ISN'T IT GRAND.

Don't lie, admit you are just dying to mention Stalin, Jesuits and the 1611 KJV bible.

Video: Debris from Japan tsunami washing up onto Washington shores – ‘Unprecedented in recorded history; a debris field the size of California’

"Debris from last year's earthquake and tsunami in Japan is already washing up on Washington beaches, and much more is expected."
