Experts warn that Japan’s second largest lake with a surface area of 220 sq. km is quietly but steadfastly accumulating radioactive cesium […]
[It] is not only rich with fishery resources but whose water is used for irrigation, industrial purposes, and even for consumption as drinking water for 960,000 people in Ibaraki Prefecture. Furthermore, no one knows how and by how much the problem has worsened over the months, except for one obvious thing: it hasn’t gone away. […]
