It was actually a dust and smoke cloud in both of the bombs dropped over Japan in the last days of the war. The cloud contains three main classes of material: the remains of the weapon and its fission products, the material acquired from the ground (for burst altitudes below the fallout-free altitude, which depends on the weapon yield), and water vapor. The bulk of radiation contained in the cloud consists of the nuclear fission products; neutron activation isotopes from the weapon materials, air, and the ground debris are only a minor fraction.
In Honkawa Elementary School in 2013 a picture of the Hiroshima atom bomb cloud, believed to have been taken about 30 min after detonation was found. But in Nagasaki, the only pictures were taken moments after the blast was done. Witness said that the cloud lasted until night time.

See: Atomic bombings of Hiroshima and Nagasaki.
How long was the wait to get back bombings of Hiroshima and Nagasaki?
3 days
What were the long term effects on the offspring during the atomic bombing of hiroshima and nagasaki?
Babies born with defects.
Do people still live in Hiroshima and Nagasaki?
Yes, in fact they are both large, thriving cities. Nuclear airbursts like Hiroshima and Nagasaki do not have as much long-lasting radiation as ground or ocean bursts.

Why does the atomic bomb make a mushroom cloud?
== == Any thermonuclear device creates a mushroom cloud because of the immense heat. Any explosion can create a mushroom cloud, as long as it can heat the gases enough to allow them to rise. The rising air lifts off the ground rapidly, until it reaches a height where the other gases are more dense. The falling gases then get sucked back into the "stem" as the rising gases are moving rapidly enough to create a vacuum. The "mushroom" phenomenon is created whenever there is a density differential between two bodies of fluid, called a "Rayleigh-Taylor Instability". This is mathematically dictated by Navier-Stokes equations.
How long did the iceland ash cloud last for?
The Iceland ash cloud from the Eyjafjallajökull volcano eruption in 2010 lasted for about a week, causing widespread disruption to air travel in Europe.

I don't understand your question,please clarify. What kind of mushroom?
Why does the hydrogen bomb make a mushroom cloud?
Every explosion happening in an atmosphere makes a mushroom cloud; whether the explosion is a tiny firecracker, a hand grenade, a conventional bomb (e.g. the three explosions shown in the photo above), an atomic bomb, a hydrogen bomb, an explosive volcanic eruption, a meteor exploding in midair due to thermal stresses (e.g. comet Shoemaker-Levy 9 at Jupiter), a meteor impact making a crater, etc. How visible the mushroom cloud is and how long it persists depends on the yield of the explosion (how big it was in terms of energy released). The mushroom shape is simply an effect of buoyancy: hot gasses produced by the explosion are less dense than the surrounding air so they rise with the cap of the mushroom being a toroidal vortex (similar to a smoke ring).Similar clouds can be observed in the smoke above large fires and water vapor above cooling towers, but usually missing a well defined cap.Underground salt domes (that contain petroleum and natural gas) result from the same density phenomenon, with less dense salt rising through more dense rock. However here in most cases only the cap remains without the stem.
How long does it take to sterilize mushroom substrate?
Sterilizing mushroom substrate typically takes around 1-2 hours.
Does cloud have a long vowel or short vowel?
Neither. The OU pair in cloud has an OU/OW sound as heard in crowd.
