"Little Boy" was the codename of the atomic bomb dropped on Hiroshima on August 6, 1945 by the Boeing B-29 Superfortress Enola Gay, piloted by Colonel Paul Tibbets of the 393d Bombardment Squadron, Heavy, of the United States Army Air Forces.
Up to August 6th, occasional bombs, which did no great damage had fallen on Hiroshima. Many cities roundabout, one after the other were destroyed, but Hiroshima itself remained protected. There was almost daily observation planes over the city but none of them dropped a bomb. The citizens wondered why they alone had remained undisturbed for so long a time. There were fantastic rumors that the enemy had something special in mind for this city, but no one dreamed that the end would come in such a fashion as on the morning of August 6th.
Perhaps a half-hour after the explosion, a procession of people began to stream up the valley from the city. Toward noon, our large chapel and library are filled with the seriously injured. The procession of refugees from the city continues. Soon comes news that the entire city has been destroyed by the explosion and that it is on fire.
Currently there is a team of American and Japanese scientists studying the effects of the atomic bombs. There is still radiation from those two bombs in Japan and surrounding areas but the levels are significantly lower after sixty years than when the bombs were first dropped. The cities of Nagasaki and Hiroshima were rebuilt fairly soon after they were damaged by the bombs and a horrendous typhoon that did worse damage weeks later. The officials of Japan did not have full understanding about the duration of radiation's effects when they rebuilt the cities. The team of scientists have kept careful records of post sicknesses and the levels of radiation. They will continue until the radiation levels are safe again. If you want to learn more there is an excellent show on the history channel about this team of scientists. I believe they have a web site but I am not absolutely certain of this. I forget the name of the team.
This is a complicated question to answer. Different radioisotopes have different halflifes. It is usually necessary to conduct radiological surveys to test the area afterwards and isolate hotspots. No single answer can be given.
Hard to say exactly as it depends on the halflives of a wide variety of radioisotopes produced by the bomb and what happens to be considered safe exposure levels. Following a large nuclear war, what will be considered safe exposure levelsare likely to be noticeably higher than what is now considered safe exposure levels as uncontaminated areas may be rare.
It was only one bomb over Hiroshima. That was a nuclear weapon and blast was like flash.
Nagasaki received only one bomb. It was an atomic one. It detonated at 11.01
It was only an atomic bomb dropped over Hiroshima so that didnt take long.

The financial cost of Hiroshima after the atomic bomb dropped in 1945 was immense. It is estimated that the initial damage was equivalent to about $10 billion in today's currency, including the destruction of buildings and infrastructure. However, the long-term economic impact is harder to quantify, as the city's recovery and rebuilding took many years.
The first atomic bomb was launched in 1945, by the US. It incinerated Hiroshima and Nagasaki, Japan during WWII The above is half true. That was the first time an atomic bomb was used in war, but the first atomic bomb was detonated at the the Trinity Site in White Sands Missile Range, on July 16, 1945.
august 6 1945 was the first and the second bomb was on august 9 1945.add. The first bomb exploded under the Manhattan Project was on July 16 1945, not long before the second and third bombs (above) were dropped in wartime.

It took only one atomic bomb.

the one dropped on hiroshima (uranium) was called little boy. it was 3 metres long and thin.The one dropped on nagasaki was call fat man. this one contained plutonium and was 4 metres long and much rounder.The plane was callled the enola gay (B-29) and the pilot was callled tibbins.

it was either kill a few thousand with an atomic bomb, or invade japan and lose millions of japanese and americans. Saves lives in the long run.
Wherever the bomb is dropped a lot of people will be killed during the explosion and more from radiation for a long time after. Immediately after the bomb is dropped we will do what we have always done as Americans and go kick some a**.

The Battle of Midway occurred in June, 1942. The first atomic bomb was not used until August, 1945.
The only time atomic bombs were dropped in combat was in 1945.The last time either the US or USSR dropped an atomic bomb for test purposes was in 1963.When my brother was in the army in Germany doing maneuvers with nuclear antitank landmines, he dropped an atomic bomb on his hand squashing one finger like a stepped on hotdog. (of course this is a different sense of meaning of the word dropped) This was in the late 1970s.Other countries may have dropped atomic bombs for test purposes more recently.
