Graph of the Day: Radioactive Cesium in Metropolitan Tokyo Soil, August 2011
Tokyo Metropolitan Soil Testing Results
(released 2011/8/8) Over 60,000 Bq/kg of Cesium-134 and Cesium-137 detected in Tokyo! As our first work of our Nationwide Soil Testing Project, we tested soil samples from 132 areas in the Tokyo metropolitan area, including Tokyo, Chiba, Saitama, Kanagawa, and Ibaraki. Our results show how much radioactive particles fell over the Tokyo Metropolitan area. Some of the higher numbers reveal that there are serious “hot spots” within the city.
