TOKYO (AP) - Workers have discovered new pools of radioactive water leaking from Japan's crippled nuclear complex that officials believe are behind soaring levels of radiation spreading to soil and seawater.
Crews also detected plutonium - a key ingredient in nuclear weapons - in the soil outside the complex, though officials insisted Monday the finding posed no threat to public health.
Plutonium is present in the fuel at the complex, which has been leaking radiation for more than two weeks, so experts had expected to find traces once crews began searching for evidence of it this week.
The Fukushima Dai-ichi power plant was crippled March 11 when a tsunami spawned by a powerful earthquake slammed into Japan's northeastern coast. The huge wave destroyed the power systems needed to cool the nuclear fuel rods in the complex, 140 miles (220 kilometers) northeast of Tokyo.
