Do nukes destroy matter?

Modern nuclear weapons work by combining chemical explosives, nuclear fission, and nuclear fusion. The explosives compress nuclear material, causing fission; the fission releases massive amounts of energy in the form of X-rays, which create the high temperature and pressure needed to ignite fusion.

How much destruction can a nuke cause?

Summary of the effects

Effects	Explosive yield / height of burst
1 kt / 200 m	20 kt / 540 m
Urban areas completely levelled (20 psi or 140 kPa)	0.2	0.6
Destruction of most civilian buildings (5 psi or 34 kPa)	0.6	1.7
Moderate damage to civilian buildings (1 psi or 6.9 kPa)	1.7	4.7

Can you survive a nuclear bomb in a bank vault?

While skin is good enough protection for alpha radiation, once a radioactive particle has entered the body it can do much damage. So you can survive a nuclear attack in a vault if: You can open it from the inside. It is outside the blast area.

What is the deadliest nuke in the world?

Tsar Bomba
Tsar Bomba, (Russian: “King of Bombs”) , byname of RDS-220, also called Big Ivan, Soviet thermonuclear bomb that was detonated in a test over Novaya Zemlya island in the Arctic Ocean on October 30, 1961. The largest nuclear weapon ever set off, it produced the most powerful human-made explosion ever recorded.

What is the least powerful nuke?

The W54 (also known as the Mark 54 or B54) was a tactical nuclear warhead developed by the United States in the late 1950s. The weapon is notable for being the smallest nuclear weapon in both size and yield to have entered US service.

Is there a nuke bigger than the Tsar Bomba?

The Tsar bomba could have been 100+ mt, but they wisely decided to limit it to 57mt by replacing the uranium in the third stage with lead. There has been no other bomb detonated (or even assembled) that was larger. Yes, the AN602.

Could you really survive a nuke in a fridge?

GEORGE LUCAS IS WRONG: You Can’t Survive A Nuclear Bomb By Hiding In A Fridge. “The odds of surviving that refrigerator — from a lot of scientists — are about 50-50,” Lucas said. But science has spoken, and it says something a little different.

What happens if a nuke goes off 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. Vast amounts of energy are absorbed by phase change (water becomes steam at the fireball boundary).
