Japan Radiation May Be Spreading In Seawater

Workers discovered new pools of radioactive water leaking from Japan's crippled nuclear complex, officials said Monday, as emergency crews struggled to pump out hundreds of tons of contaminated water and bring the plant back under control.

Officials believe the contaminated water has sent radioactivity levels soaring at the coastal complex and caused more radiation to seep into soil and seawater. Crews also found traces of plutonium in the soil outside of the complex on Monday, but officials insisted there was no threat to public health.

Plutonium – a key ingredient in nuclear weapons – is present in the fuel at the complex, which has been leaking radiation for over two weeks, so experts had expected some to be found once crews began searching for evidence of it this week.

Tokyo Electric Power Co. official Jun Tsuruoka said only two of the plutonium samples taken Monday were from the leaking reactors. The other three were from earlier nuclear tests. Years of weapons testing in the atmosphere left trace amounts of plutonium in many places around the world.
