EAS-Emergency Alert System — Designated radio and TV stations that will broadcast safety information in the event of an emergency.
Emergency Sirens — There are 156 sirens placed within the 10 mile radius of Indian Point. In the event of an emergency at Indian Point the sirens would sound for four minutes in an increasingly loud, wavering tone.
Emergency Planning Zone (EPZ) — The area designated by the federal government within a 10-mile radius of a nuclear power plant for which plans have been put in place to protect people in the event of a radiological emergency.
Emergency Response Planning Area (ERPA) — The 10-mile Emergency Planning Zone (EPZ) is further divided into 51 Emergency Response Planning Areas, each identified by its own number. In an emergency, public safety officials will provide specific information for different ERPAs, so it's important to know the number of the ERPA you live in. To find your ERPA number, go the Emergency Planning Zone page and select the county you live in.
Evacuation — A protective action intended to prevent or reduce exposure to radioactive materials. In an evacuation, you would be instructed to leave your home and go outside of the Emergency Planning Zone to the home of a relative or friend or to a General Population Reception Center. General Population Reception Centers are identified on the map in the back of this booklet.
General Population Reception Center — A location outside of the Emergency Planning Zone (EPZ) where people who have evacuated can go. You can find your General Population Reception Center on the map. At the General Population Reception Centers, evacuees would receive initial assistance, including personal monitoring for radiation contamination, receive KI-potassium iodide, first aid or directions either to a place to stay or a medical facility.
Incident Levels — The federal government has designated four classifications for incidents at nuclear power plants. Each classification corresponds to the degree of seriousness of an incident. See Sirens.
KI — The chemical symbol for a drug called potassium iodide. KI-potassium iodide comes in the form of tablets. KI protects only the thyroid gland from just one kind of radiation — radioactive iodide. It can be obtained through your county and kept on hand in your home. KI is also available over the counter (without a prescription) at local pharmacies. In the event of a nuclear emergency, you could be instructed to swallow a KI-potassium iodide tablet. It should be taken only when directed by public officials.
Protective Action — Any action taken to protect the public's health in response to an emergency. Protective actions in a radiological emergency could include sheltering in place (staying indoors), evacuating the area and/or swallowing KI-potassium iodide.
Radiological Emergency — An emergency where radioactive materials in significant concentrations escape into the environment. If the concentrations of the materials are high enough, they could be dangerous to health.
Radioactive Release — Introduction or leak, of any radioactive materials into the environment.
School Reception Centers — Schools outside of the Emergency Planning Zone where school children are relocated during a radiological emergency. If children are in school during an incident, at the first indication of a problem, they will be taken by bus to a School Reception Center as a precautionary action. Your children will be cared for at these Centers. You can find your children's School Reception Centers on the map.
Sheltering — Also called “sheltering-in-place.” This is a protective action in which you are instructed to stay indoors with windows and doors tightly shut and all ventilation systems turned off. Under certain circumstances, it is the better way to limit exposure to radioactive materials.
