Japan detects “extraordinarily high levels” of radioactivity off Sendai - 30 km out - 45 meters below surface

Japan’s science ministry has detected extraordinarily high levels of radioactive cesium in seafloor samples collected off Miyagi and Ibaraki Prefectures. [...]

Radioactive substances were found in all locations, including those off Miyagi and Ibaraki Prefectures, which had not been previously investigated.

Radioactive cesium 137, measuring 110 becquerels per kilogram or about 100 times the normal level, was found in samples collected from the seabed 30 kilometers off Sendai City and 45 meters beneath the surface. [...]

[Professor Takashi Ishimaru of the Tokyo University of Marine Science and Technology] said monitoring must be stepped up over a larger area, as radioactive materials in the seabed do not dissolve quickly, and can accumulate in the bodies of larger fish that eat shrimp and crabs that live on the seafloor.
