Although the danger of a strategic attack on the United States has diminished, an accident or a terrorist incident involving nuclear material is possible, if unlikely. The danger from a nuclear release is exposure to radiation. The area of a radioactive release is determined by the amount released, wind direction/speed and weather conditions. Radioactive materials or radiation released into the environment can be dangerous because of the harmful effects of certain types of radiation on the body.

The longer a person is exposed to radiation and the closer the person is to the radiation, the greater the risk. In general, there are three ways to minimize radiation exposure: distance, shielding and time.

Distance: The more distance between you and the source of the radiation, the better.

Shielding: Like distance, the more heavy, dense material between you and the source of the radiation, the better.

Time: Most radioactivity loses its strength fairly quickly. The less time you spend in an area where radiation is a risk, the better.
