The Nuclear Regulatory Commission defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of, concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about, concerned primarily with ingestion of food and liquid contaminated by radioactivity. The 2010 U.S. population within of Robinson was 32,675, an increase of 2.6 percent in a decade, according to an analysis of U.S. Census data for msnbc.com. The 2010 U.S. population within was 893,536, an increase of 10.3 percent since 2000. Cities within 50 miles include Columbia.
