The observers were sure it was 12 miles since glass was broken up to 12 miles but there was no consistency in the long range blast damage. Observers often thought that they had found the limit, and then 2,000 feet farther away would find further evidence of damage.

There are three forms of damage caused by a nuclear detonation:BlastFireRadiationOf the three, blast and fire are typically the most devastating over the largest area. Radiation, however, is the longest lasting and depends on the nuclear components of the device.Typically, destructive distance is referred to as the blast radius. The bomb dropped on Hiroshima, Little Boy (the benchmark for most of what we know), had a blast radius of one mile. That is that the wave from the detonation of the device at about 500 meters altitude spread out at about the speed of sound for one mile from ground zero (a two mile diameter). The blast radius is directly related to the yield of the device. Little boy being relatively small, about 40 kt (kiloton). The average yield at the height of the Cold War was about five mt (megaton). This yield device, with a surface burst detonation (the least destructive--compared to subsurface or airburst) produces a blast radius of about 20 miles.In addition to the blast radius is the area of firestorm and high level radiation which is roughly twice that of the blast radius.There are a number of nuclear blast emulators available on line. One is linked below.Little Boy was about 15 kilotons, not 40 kilotons. Fat Man was a little more than 20 kiloton.
This is impossible to answer with any accuracy as it depends on too many variables, including:burst height/depthwind speed & directionprecipitation (causing rainout hotspots)low fallout (clean) or normal fallout or high fallout (salted/dirty) designFallout usually doesn't have a simple radius like blast & thermal, it comes down in an elongated plume driven by changing wind directions.
Little Boy was the nuclear bomb detonated over Hiroshima. It used uranium and had an explosive blast equivalent to 12,500 tons of TNT. A 1 megaton hydrogen bomb, hypothetically detonated on the earth's surface, has about 80 times the blast power of that 1945 explosion. Considering the tonnage of a bomb to be contant, The blast radius varies dependent on whether it is a ground burst or an airburst. Further, the height of the airburst above ground affects the radius too. At a height of 1900 feet above ground, Little Boy produced a blast radius of 1 mile; an area of some 4.7 square miles.

standard blast radius is around 3-8 feet
