How much area can a atom bomb destroy?

The volume the weapon’s energy spreads into varies as the cube of the distance, but the destroyed area varies at the square of the distance. Thus 1 bomb with a yield of 1 megaton would destroy 80 square miles. While 8 bombs, each with a yield of 125 kilotons, would destroy 160 square miles.

How far away from an atomic bomb is safe?

This will help provide protection from the blast, heat, and radiation of the detonation. When you have reached a safe place, try to maintain a distance of at least six feet between yourself and people who are not part of your household.

What is the blast radius of an atomic bomb?

In both cities the blast totally destroyed everything within a radius of 1 mile from the center of explosion, except for certain reinforced concrete frames as noted above. The atomic explosion almost completely destroyed Hiroshima’s identity as a city.

What can withstand an atomic bomb?

Once you survive the initial blast, you’re going to want as much dense material — concrete, bricks, lead, or even books — between you and the radiation as possible. Fallout shelters are your next safest bet, as they will provide the highest protection from this debris.

What would happen if a nuke detonated underwater?

Unless it breaks the water surface while still a hot gas bubble, an underwater nuclear explosion leaves no trace at the surface but hot, radioactive water rising from below. About one second after such an explosion, the hot gas bubble collapses because: The water pressure is enormous below 2,000 feet (610 m).

What is the blast radius of the strongest nuke?

When the giant bomb finally detonated about 13,000 feet (4 kilometers) over its target, the blast was so powerful that it destroyed everything within a nearly 22-mile (35-kilometer) radius, and generated a mushroom cloud that towered nearly 200,000 feet (60 kilometers).
