Quick Answer
Regular building materials can be used for shelter construction in a survival situation, but they must be carefully selected and prepared to provide adequate protection from radiation and other hazards.
Choosing Materials for Shelter Construction
When selecting materials for shelter construction in a post-nuclear environment, prioritize items that offer natural shielding, such as earth, sandbags, or concrete. Plywood, oriented strand board (OSB), and other wood products can be used for walls and roofing, but they should be at least 6 inches thick to provide adequate protection. Metal roofing and siding, such as aluminum or steel, can also be effective, but ensure they are at least 1/4 inch thick.
Assembling the Shelter
When assembling the shelter, consider the principles of time, distance, and shielding. The farther you are from the source of radiation, the less exposure you will receive. A minimum distance of 1 mile (1.6 kilometers) from the epicenter of a nuclear explosion is recommended for short-term exposure. However, if space permits, aim for a distance of 10 miles (16 kilometers) or more. Within the shelter, use layers of materials to create a shielded interior. For example, a 6-inch thick layer of earth or sandbags can be used as an outer layer, with a 2-inch thick layer of plywood or OSB as an inner layer. This provides a total shielding thickness of 8 inches, which can reduce radiation exposure by 90%.
