2 U.S. Naval Vessels Pull Out of Japan Due to Radiation Fears

TOKYO -- Two US Navy ships pulled out of the Japanese base at Yokosuka due to fears over rising radiation, Fox News Channel reported Monday.

The USS George Washington and the USS Lassen left the base, which is located south of Tokyo, as a precautionary measure "to ensure a state of readiness in the long term for the defense of Japan," the US Navy said in a statement.

The USS George Washington, which is a Nimitz-class aircraft carrier, was removed from the area for regularly scheduled maintenance, a military official told Fox News. The USS Lassen is an Arleigh Burke-class destroyer.

Last week, the US Navy moved the carrier USS Ronald Reagan away from the Japanese coast on concerns radioactive material was blowing in its direction, but later moved it back.

Earlier, the State Department said it was making potassium iodide available to US government workers and their dependents located in the vicinity of the troubled nuclear plant at Fukushima.
