Post-Fukushima Radiation Mapped via ieee spectrum

Cesium in soil a problem for agriculture

2 December 2011—More than eight months after a tsunami triggered a meltdown at the Fukushima Dai-ichi nuclear power plant, the broad impact of the accident on Japan’s people and lands is becoming clear.

Three recently published academic studies show that while direct radiation exposure of Fukushima residents isn’t as high as was initially feared, soils across northeastern Japan are contaminated and could affect public health for decades through the produce farmed there. The research, combined with a map of soil radiation—which was based on measurements made during helicopter flights and released by Japan’s science ministry—shows substantial soil contamination in the prefectures of Fukushima and its neighbors: Miyagi and Iwate to the north, Ibaraki and Chiba to the south, and Tochigi and Gunma to the southwest.
