Storm caused radioactive leaks at Fukushima

Heavy rain at the Fukushima nuclear plant caused a leak of radioactive water containing a cancer-causing isotope, possibly into the sea, its operator said on Monday, as a typhoon approaching Japan threatened further downpours.

It is the latest in a long line of setbacks at the site and further undermines agreements between operator Tokyo Electric Power (Tepco) and the government, which limit the level of radioactive contamination in water that goes outside the plant.
