Total destruction spread over an area of about 3 square miles. Over a third of the 50,000 buildings in the target area of Nagasaki were destroyed or seriously damaged.

How far is the fallout from a nuclear bomb?

A 1,000-kiloton nuclear blast might produce third-degree burns up to 5 miles away, second-degree burns up to 6 miles away, and first-degree burns up to 7 miles away, according to one estimate from AsapScience. People up to 53 miles away could also experience temporary blindness.

How far did Hiroshima damage?

Flash ignition of dry, combustible material was observed as far as 6,400 feet from X in Hiroshima, and in Nagasaki as far as 10,000 feet from X. Severe damage to gas holders occured out to 6,500 feet in both cities. All Japanese homes were seriously damaged up to 6,500 feet in Hiroshima, and to 8,000 feet in Nagasaki.

Is there still fallout in Hiroshima?

Is there still radiation in Hiroshima and Nagasaki? The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies.

How big was the little boy blast radius?

approximately 1.3 kilometres Its lethal radius was approximately 1.3 kilometres (0.8 mi), covering about half of the firestorm area. An estimated 30% of immediate fatalities were people who received lethal doses of this direct radiation, but died in the firestorm before their radiation injuries would have become apparent.

What is black rain?

The "black rain" that fell after the atomic bombings of Hiroshima and Nagasaki has been generally believed to contain radioactive materials. During 1949-1961 the Atomic Bomb Casualty Commission conducted surveys that included a query about exposure to the rain that fell a short time after the bombings.

What’s the blast 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.
