# How big is the blast radius of a nuclear bomb?

## How big is the blast radius of a nuclear bomb?

The blast radius of a nuclear bomb is variable. According to the National Terror Alert Center, the contributors to the blast radius of a nuclear bomb include the yield, fuel, weather, geography, whether the explosion was in the air or at the surface and even time of day. The blast radius of the bomb dropped on Hiroshima was about 1.7 miles.

## What are the different types of nuclear weapons?

A nuclear weapon is defined as an explosive that has such an intense power behind it that it can cause massive amounts of damage in faraway places. To start breaking down the explanation of nuclear weapons, let’s talk about the two types of explosives at hand. There are two types of explosives, including fission bombs and thermonuclear bombs.

What kind of bomb is a fission bomb?

Fission bombs are detonated by way of a nuclear fission reaction, hence the name. However, this is not the only method of activating a nuclear weapon. Bombs that are detonated through a combination of fission and fusion are called thermonuclear bombs.

Which is the highest yield nuclear bomb ever made?

The Mk-41 or B41 had a mass of 4800 kg and yield of 25 Mt; this equates to being the highest yield-to-weight weapon ever produced. All were gravity bombs carried by the B-36 bomber (retired by 1957). The highest-yielding test series conducted by the US.

### How big is the yield of an atomic bomb?

The Atomic Bomb. The enormous amount of nuclear energy that is released by this process produces a large amount of heat and electricity. A nuclear weapon’s explosive power is measured in yield, which is expressed in tons of TNT. Fission, or atomic bombs, can be as small as one kiloton (KT) of explosive power or as large as several hundred kilotons.

### How much energy is released in a nuclear bomb?

But generally speaking, there are some predictable stages of a nuclear bomb blast. As the video above explains, approximately 35 percent of the energy of a nuclear blast is released in the form of thermal radiation.

How can you predict the radius of an atomic bomb?

To be able to accurately predict how a 5% increase in the energy of a bomb will affect the radius of the explosion you need a lot of data. Which ultimately means carrying out a lot of experiments.

What is the radius of a Ground Zero explosion?

Approaching ground zero, all buildings will be rubble and rubble may be 30 feet deep or more. The SD zone may have a radius on the order of a 0.5 mile (0.8 km) for a 10 KT detonation. Blast overpressure that characterizes the SD zone is 5-8 psi and greater.

#### How big is the fireball from a nuclear bomb?

Fireball (0.56 miles wide) — In the area closest to the bomb’s detonation site, searing flames incinerate most buildings, objects, and people. Radiation (1.24 miles wide) — A nuclear bomb’s gamma and other radiation are so intense in this zone that 50% or more of people die within “several hours to several weeks,” according to Nukemap.

#### How big is the damage zone after a nuclear detonation?

Rubble in streets is estimated to be impassable in the SD zone making timely response impracticable. Approaching ground zero, all buildings will be rubble and rubble may be 30 feet deep or more. The SD zone may have a radius on the order of a 0.5 mile (0.8 km) for a 10 KT detonation.

What was the yield of a nuclear bomb?

It was a very compact implosion-type nuclear weapon design, designed for tactical use and had a very low yield for a nuclear weapon, in the range of 10 to 1,000 tons TNT equivalent .

How much energy is released in a Nuclear Blast?

As the video above explains, approximately 35 percent of the energy of a nuclear blast is released in the form of thermal radiation. And seeing as thermal radiation travels at approximately the speed of light, the first thing that will hit you is a flash of blinding light and heat.
