Typical 10-Mile Plume Exposure Pathway EPZ Map

Figure 1 depicts a typical 10-mile plume exposure pathway EPZ map. The center of the map is the location of the commercial nuclear power plant reactor building. Concentric circles of 2, 5, and 10 miles have been drawn and divided into triangular sectors identified by letters from A to R. Municipalities identified to be within the 10-mile EPZ have been assigned numbers from 1 to 24. The triangular sectors provide a method of identifying what municipalities are affected by the radioactive plume as it travels.
