More Fukushima Troubles - Japan

One of the tanks storing highly radioactive water from Japan's Earthquake damaged Fukushima nuclear power plant has leaked about 300 tons of contaminated radioactive water.

The radiation is about five times the annual exposure limit for plant workers. Seawater contamination is not an immediate concern, because the tank is 330 feet (100 meters) from the coast, but Japan's nuclear watchdog said the leaked water could enter the ocean by a drain gutter.

Four other tanks had similar leaks in 2012, but this leak is the worst one yet. Sandbags were piled around to soak up the flow, but radioactive water still soaked into the ground. Workers are racing to pump the water out of the puddle and tank before the arrival of heavy rain predicted for later in the day.
