Stay inside your home or office unless instructed by civil authorities to leave. Close the windows, turn off the heating or air-conditioning, and stay near the center of the building. Once the initial blast is over, radioactive materials may be spread in the smoke and debris in the air. By staying inside you will reduce any potential exposure to airborne radioactive material. If there is a basement, go there.
Listen to the Radio
When you learn that radioactive materials have been released in an area near you — either accidentally or intentionally — tune your radio to the emergency broadcasting network for instructions. Government agencies will let you know how to protect yourself. Keep a battery-powered radio handy in case electrical power goes out in your area.
If you believe you have been exposed to radioactive materials, you should carefully remove your outer layer of clothing and put it in a plastic bag; then take a warm shower to rinse off any radioactive materials. Place the sealed plastic bag in a room away from people.
Watch What You Eat
Avoid drinking fresh milk or eating fruits and vegetables grown in the affected area. Wait until the Department of Health announces that produce and dairy products are safe to eat and drink. Milk, fruit and vegetables are okay to eat if they were bought or picked before the radiation was released and were stored indoors. Food stored in cans or bags is also safe to eat. Be sure to thoroughly rinse off containers before opening.
