How much area can a nuclear bomb destroy?

Calculations demonstrate that one megaton of fission, typical of a two megaton H-bomb, will create enough beta radiation to blackout an area 400 kilometres (250 mi) across for five minutes.

How far does an atomic bomb effect in miles?

Heat is an issue for those closer to the blast. Mild, first degree burns can occur up to 11 km (6.8 miles) away, and third degree burns – the kind that destroy and blister skin tissue – could affect anyone up to 8 km (5 miles) away.

How deep does a bunker have to be to survive a nuke?

For example, an earth penetrating weapon using the 1.2 megaton B83 warhead—the highest yield weapon in the U.S. nuclear stockpile—could crush underground bunkers to a depth of about 1000 feet. Deeper bunkers can be constructed with modern tunneling equipment, and are essentially invulnerable to nuclear attack.

What are the effects of a nuclear bomb on humans?

EFFECTS ON HUMANS Blast. Nuclear explosions produce air-blast effects similar to those produced by conventional explosives. The shock wave can directly injure humans by rupturing eardrums or lungs or by hurling people at high speed, but most casualties occur because of collapsing structures and flying debris.
