## How big is the nuclear explosion radius?

The initial radiation pulse from a 1 KT device could cause 50% mortality from radiation exposure, to individuals, without immediate medical intervention, within an approximate ½ mile (790 m) radius. This radius increases to approximately ¾ mile (1200m) for a 10 KT detonation.

## What was the blast radius of the Tsar Bomba?

Ionization of the atmosphere caused interference to radio communications even hundreds of kilometers from the test site for about 40 minutes. Radioactive contamination of the experimental field with a radius of 2–3 km (1.2–1.9 mi) in the epicenter area was no more than 1 milliroentgen / hour.

How many miles from a nuclear bomb is safe?

Those closest to the bomb would face death, while anyone up to 5 miles away could suffer third-degree burns. People up to 53 miles away could experience temporary blindness. But a longer-term threat would come in the minutes and hours after that explosion.

### What is the blast radius of a 20 megaton bomb?

260 meters
The first atomic bomb According to the NukeMap, a weapon with a 20-kiloton yield produces a fireball with a radius of 260 meters, making its total width the size of 5 football fields. It would spew deadly radiation over an area 7 miles in width, and would produce third-degree burns in an area over 12 miles in width.

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