  Importance of Shelter Back Next
  A basement provides some protection from radioactive fallout. Shelter provides time, distance and shielding

As discussed in Unit 1, the three important methods of reducing radiation exposure are time, distance, and shielding. To minimize exposure to fallout, these methods are implemented by seeking shelter.

If a warning is given, or fallout starts to arrive, proceed to shelter that provides the best possible shielding. These include locations such as basements, interior rooms of a house, highway culverts, etc.

Remember that fallout consists of particles of earth, fission products and other materials returning to the earth's surface. If dust-like particles are visible in the air or on surfaces, they should be considered a radiation hazard.
