Based on a widely used definition of average normal exposure for humans —360 millirems per year of radiation from rocks, cosmic rays and manmade sources—even those levels would be safe for humans, said Ron Chesser , director of the Center for Environmental Radiation Studies at Texas Tech University.

The Energy Department said U.S. aircraft and ground measurements detected radiation levels around some areas of the plant, mostly in a northwest direction within 25 miles of the plant, that exceeded 12.5 millirems per hour over the course of three days last week.

Reactor Monitor In the U.S., if those radiation levels were sustained for four days—meaning people were exposed to a total of more than 1,200 millirems—it would trigger an evacuation, or an order for residents to take shelter under Environmental Protection Agency guidelines, the Energy Department said.
