[2:19 a.m. ET, 4:19 p.m. Tokyo] A small amount of radioactive Cesium has escaped into the air surrounding a nuclear plant in northeastern Japan’s Fukushima prefecture, Japan’s Nuclear and Industrial Agency said.
The agency said there was a strong possibility that this was caused by the melting of a fuel rod, adding that plant engineers were continuing to cool the fuel rods by pumping water around the rods.
