UNIT 5: Nuclear Threat
LESSON: Protective Measures
|Importance of Shelter|
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.
