fallout shelter
Quick Summary
A fallout shelter is an underground structure designed to protect people from radioactive fallout. Fallout refers to airborne radioactive contaminants that settle on Earth, often resulting from nuclear explosions or accidents. These shelters became a significant concern following nuclear bomb tests, as the radiation dose from fission products could be intense enough that survival would depend on remaining in such protected spaces for weeks. The first Fallout electronic game, released in 1997, featured a postapocalyptic world where characters resided in a fallout shelter known as Vault 13.123
