# Question: What Is The Blast Radius Of A Atomic Bomb?

## How long after a nuclear bomb is it safe?

The US Department of Health and Human Services recommends staying indoors for at least 24 hours in the event of a nuclear explosion.

After 48 hours, the exposure rate from a 10-kiloton explosion (the type that might damage but not destroy a city) goes down to just 1%..

## What is the blast radius of a hydrogen bomb?

NUKEMAP 3D calculates the Goldsboro bomb as a fireball incinerating everything in a radius of 1.05 miles from ground zero, a lethal radiation zone (500 rems of radiation in an instant, when no more than 100 rems over an entire year is considered safe) extending 1.84 square miles, a pressure wave of 20 pounds per square …

## How do you calculate the blast radius of a nuclear bomb?

Divide the converted value by 5,280, the number of feet in one mile; 9,450 feet would be 1.79 miles. Calculate the blast radius. Square the distance of the blast and multiply it by pi (3.14). With a 1.79 mile distance, the blast radius of a 2-psi overpressure would be 10.1 square miles.

## Can you survive a nuclear bomb 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.

## How do you survive a nuclear fallout?

GET INSIDEGet inside the nearest building to avoid radiation. … Remove contaminated clothing and wipe off or wash unprotected skin if you were outside after the fallout arrived.Go to the basement or middle of the building. … Stay inside for 24 hours unless local authorities provide other instructions.More items…

## Can a bomb explode in space?

This EMP would fry hundreds of nearby satellites, put International Space Station astronauts at risk of radiation poisoning, and disrupt substantially more of Earth’s power grid. Fortunately, you needn’t worry about a nuclear bomb of this caliber being detonated in space.

## Can a nuclear bomb destroy a whole city?

A nuclear device no larger than traditional bombs can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy.

## How much area can a nuclear bomb destroy?

Radiation radius: 7.49 km or covering 176 Square km, Air blast radius: 12.51 km or covering 491square km, Thermal radiation radius: 77.06 km or covering 18626 square km. It was about 3,333 times more powerful than the Little Boy.

## Was there a 3rd atomic bomb?

On August 13, 1945—four days after the bombing of Nagasaki—two military officials had a phone conversation about how many more bombs to detonate over Japan and when. According to the declassified conversation, there was a third bomb set to be dropped on August 19th.

## Can you survive a nuclear bomb in a pool?

So surviving the thermal pulse and the heat of the fireball at the bottom of a pool, yes, that will work, and will also keep you from the worst of the radiation pulse. The shock-wave will be mostly reflected, and the blast-wave will be small due to the proximity of ground zero.

## Can you survive a nuclear blast?

A government safety expert says it’s entirely possible to survive a nuclear explosion and its aftereffects. The prospects for survival are even better if there are several minutes of warning, something Hawaii’s ballistic-missile-threat system can provide.
