Obama aide: Little chance that Japan radioactivity will drift to U.S.

There is little chance that harmful radiation from Japan's damaged nuclear plants will reach American land, said Nuclear Regulatory Commission chairman Gregory Jaczko.
"Based on the type of reactor design and the nature of the accident, we see a very low likelihood -- really, a very low probability -- that there's any possibility of harmful radiation levels in the United States or in Hawaii or any other U.S. territories," Jaczko told reporters at the White House.
Jaczko also said that his office has dispatched two NRC technical experts to Japan to help with the nuclear plant damage by last week's earthquake and tsunami.
The NRC chair also said all U.S. nuclear plants are "designed to withstand significant phenomena," such as earthquake and tsunamis. He said he could not say where U.S. plants could withstand the kind of massive, 8.9-on-the-Richter-scale kind of earthquake that hit Japan.
