在2011年3月的事故中，大量放射性物质从福岛第一核电站泄漏到大气中。3月12日、15日和20-21日发生了最严重的大气注入。每一次都形成了直径约5公里的雾，并被风带到离地面几十米高的地方。放射性物质半全球性扩散。这次事故释放到大气中的铯的总质量是11pbq，是1986年4月切尔诺贝利事故的十二分之一。其中约60%沉积在日本岛屿上。这些发现很快被Twitter、博客、谷歌地图等互联网传播所分享。

Large amount of radioactive materials were leaked into the atmosphere from the Fukushima Daiichi Nuclear Power Plant during the March 2011 accident. On March 12, 15, and 20-21 occurred the worst atmospheric injection. Each formed a fog of about 5 km across and transported by the wind several tens meters high above the earth surface. Radioactive materials spread semi-globally. Total mass of Cesium released into the atmosphere by the accident was 11 PBq, a twelfth of the Chernobyl accident in April 1986. About 60 % of which deposited on the Japanese islands. These findings were shared promptly by the Internet communication including Twitter, blogs, and Google maps.
