Supplies are crucial for survival in the shelter despite the lack of activity within it. As the distance from ground zero increases, the radiation, temperature, and shockwaves subside due to energy loss. The nuclear bomb’s explosion would cause extremely strong shockwaves, heat, and radiation in the areas close to ground zero (the area where the bomb detonates). The further away the shelter is from the blast radius, the better. Installing cooling fans or ventilation will keep the shelter in livable conditions. Thermal regulation also plays a major role in survival, as the nuclear explosion resulted in extreme temperatures, often higher than 3,000 ☌ right after detonation.ĭespite ventilation allowing fine dust to enter, it is not highly hazardous or radioactive extensive filtration systems are not required. Additionally, shelters could be built overground if they are on the middle floors of a building with more than ten floors. Underground shelters provide more protection because soil can nullify a small amount of radiation.

The material chosen for construction is often concrete or lead, which is exceptionally resistant to radiation or explosion. The shielding of fallout shelters must be dense to reduce exposure to harmful radiation. Additionally, fallout shelters must be able to hold occupants for days on end, sometimes weeks they must have amenities for basic survival. Abandoned Underground Locations in CitiesĪccording to US Saferoom, fallout shelters are underground enclosures in which the inhabitants are protected from annihilation by the nuclear bomb.
