Radiation Physicist Question:

Emergency Planning Zone (EPZ) is the area surrounding a nuclear power plant for which plans required by the NRC have been made in advance to ensure that prompt and effective actions are taken to protect the health and safety of the public in case of an incident. There is a plume exposure pathway EPZ which extends about 10 miles in radius around a plant. Its primary concern is the exposure of the public to, and the inhalation of, airborne radioactive contamination. The ingestion pathway EPZ extends about 50 miles in radius around a plant. Its primary concern is the ingestion of food and liquid that is contaminated by radioactivity.
