Massive leak of radioactive water found at Fukushima

JAPAN -- Top regulators are raising nuclear safety concerns after finding a massive leak of radioactive water at the Fukushima nuclear plant in Japan.

This discovery comes two years after a deadly earthquake and tsunami.

Officials say radiation levels surrounding the plant are 18-times higher than first thought, enough to kill a person after four hours of exposure.

The leak means the government will play a bigger role in the clean-up but not everyone feels comfortable.

"Operators are reacting too late every time in whatever they do. We say, 'don't spill contaminated water' and they spill contaminated water," said fisherman Fumio Suzuki.

Tokyo's bid for the 2020 Olympic Games could now be in jeopardy. The International Olympic Committee will make its decision later this week.
