The US Bomb Shelter and Fallout Shelter Market Size is Anticipated to Exceed USD 225.08 Million by 2033, growing at a CAGR of 5.08% from 2023 to 2033. An underground bomb shelter, usually constructed from steel and buried in the ground, offers protection from radiation and explosive impacts during a nuclear explosion. Being located further beneath the surface increases protection against fallout, which persists with a long half-life, continuing to spread residual radiation.
