Frequent Questions

What should I do in case of a radiological emergency?

Get inside, stay inside and stay tuned to radio, TV or internet. Follow instructions from local responders.

Keep in mind that evacuation may not always be appropriate depending on the situation. Sometimes, simply staying inside is a better choice for preventing or reducing radiation exposure during a radiological emergency. Buildings can provide significant protection from radiation. Getting inside quickly and staying inside after a radiological incident can limit your exposure to radiation and possibly save your life.

If you witness an incident or other emergency involving radioactive material, report it to the National Response Center at: 1-800-424-8802.
