How big is the nuclear explosion radius?

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?

“With the [atomic] bomb we dropped in Nagasaki, it killed everybody within a mile radius,” Morse told TIME on Friday, adding that a hydrogen bomb’s reach would be closer to 5 or 10 miles. “In other words, you kill more people,” he said.

How big was the Hiroshima bomb radius?

In both cities the blast totally destroyed everything within a radius of 1 mile from the center of explosion, except for certain reinforced concrete frames as noted above. The atomic explosion almost completely destroyed Hiroshima’s identity as a city.

How big was the blast radius of fat man?

1 mile
Similar fires broke out in Nagasaki, but no devastating fire storm resulted as in Hiroshima because of the irregular shape of the city. In both cities the blast totally destroyed everything within a radius of 1 mile from the center of explosion, except for certain reinforced concrete frames as noted above.

How wide was Hiroshima blast radius?

In both cities the blast totally destroyed everything within a radius of 1 mile from the center of explosion, except for certain reinforced concrete frames as noted above. The atomic explosion almost completely destroyed Hiroshima’s identity as a city.

How big of a radius did the Hiroshima bomb?

The destruction was unlike anything in the history of warfare. Hiroshima was immediately flattened. The resulting explosion killed 70,000 people instantly; by December 1945, the death toll had risen to some 140,000. The radius of total destruction was reportedly 1.6km.

What is the blast radius of a 1 megaton nuke?

Within a 6-km (3.7-mile) radius of a 1-megaton bomb, blast waves would produce 180 metric tons of force on the walls of all two-story buildings, and wind speeds of 255 km/h (158 mph).
