Title: Radioactive cesium found off of Niigata, Shizuoka, Iwate coasts: gov’t study
Date: August 4, 2012
Radioactive cesium likely from the Fukushima nuclear disaster was detected last year in a survey of ocean waters and fish off Niigata, Shizuoka, and Iwate prefectures, the government announced on Aug. 3.
“Even if taken internally, the radiation levels detected are not a risk to human health,” the Ministry of Education, Culture, Sports, Science and Technology stated. The ministry added it believes the small amount of contamination detected even in the Sea of Japan off Niigata was probably originally airborne material that made it to coastal waters through rain and river courses.
- In May last year that there were 9.1 millibecquerels of radioactive cesium per liter of seawater off Omaezaki, Shizuoka Prefecture
- In December, the survey found two becquerels per kilogram in a type of flounder in [Shizuoka]
- In May last year, the survey found dried sea floor dirt from the southeast of Sado Island [...] was contaminated with 31 becquerels of cesium per kilogram
- In the ocean off Yamada, Iwate Prefecture [...] 0.7 becquerels per liter of seawater were detected in May 2011
