Researchers find high cesium in some Pacific plankton
Scientists said Tuesday they have detected radioactive cesium from the Fukushima No. 1 nuclear plant in plankton collected from all 10 points in the Pacific they checked, with the highest levels at around 25 degrees north latitude and 150 degrees west longitude. [...]
The researchers collected plankton at 10 points in the Pacific from off Hokkaido to Guam between January and February 2012.
They detected cesium-134 in plankton at all 10 points. The density of radioactive cesium was the highest at 8.2 to 10.5 becquerels per kilogram in samples collected from waters around 25 degrees north latitude and 150 degrees west longitude. [...]
The density of cesium in seawater was highest in waters at around latitude 36 to 40 degrees north, the team said. [...]
