Atomic Bombs

Nagasaki

It was originally to have been Kokura, but heavy overcast prevented a visual bomb run so the planes diverted to the secondary: Nagasaki.

Leukemia, Lymphoma and Multiple Myeloma, Nervous system tumors and their response relation were observed for all solid nodules, adenoma, and nodules without histological diagnosis, autoimmune hypothyroidism, stomach tumors and breast diseases. The population has a long follow-up (50 years) and includes both sexes and all ages of exposure, allowing a direct compilation of risks by these factors. the population has a long follow-up (50 years) and includes both sexes and all ages of exposure, allowing a direct compilation of risks by these factors. Because of the use of Japanese family registration system, mortality data are virtually complete for survivors who remained in Japan.

The result in the coral reefs in the Bimini Island who were demolished by nuclear blast came alive again after 50 years.

Taking the question simply as it is asked - - the answer is, no.

* One crewman, a Major Ferebee ihad a nervous breakdown after the war, he was the bombardier who actually released the bomb and all the havoc this raised. * The craft's Command Pilot, Colonel Tibbets, died of natural causes a few years ago. It is true that psychiatric casualties ran high among Bomber crews owing to destruction of civil or noncombatant targets. It should be understood ( this was misrepresented in the film about the misson (Above and Beyond) that the target, Hiroshima, offered no resistance by flak or fighter intercepts.

Additionally, no member of the crew of the Enola Gay received the Congressional medal of Honor as suggested in Above and Beyond.

Firstly, to end WW2 as soon as possible. By using a nuke (atom bomb), it has saved a potential of another 3 more months of WW2 as in Japanese offical record. (Some Japanese fell that by September to November, Japanese might have surrendered but defintely would not refuse to surrender after the year 1945.) This 3 months might make the Japs more cruel to China, SEA (South East Asia), Pacific and Korea for "revenging." Secondly, to save many soldiers life, especially US and to punish the Japs severly for the attack of Pearl Harbor. Thirdly, possibly to test the Uranium bomb. Note: Before the actual use of nuke, the US had tested a plutonium (now man-made element as it had extinct) bomb in a desert. The US had enough supply of Plutonium and therefore, a uranium bomb was not able to test as the number of uranium US have is only enough for a bomb. Hence, the bombing of Hiroshima is a good test for them. (The Nagasaki one , Fat Man was again a Plutonium Bomb.)

Hiroshima was in ruins. The T-bridge's barriers had been knocked awry; utility poles stood at odd angles, and familiar landmarks were gone or unrecognizable. Buildings-even strong modern structures-had suffered significant damage, some pushed off their foundations, some gutted by fire, others utterly destroyed. Many steel and concrete buildings appeared intact at first glance, but their outer walls hid internal damage due to the downward pressure of the air burst. Cemeteries were uprooted, and churches had become rubble.

Rebuilding efforts over the decades have been fruitful. There has so much rebuilding and new buildings that the count was lost. Nowhere you fill that information.

The atomic bomb was the decision of President Harry S. Truman. He wanted to end the world war II against the Japanese and the U.S. because Japanese refused to surrender.All and all, it ended as the U.S. showing the Japanese that we were a threat and with that, world war II was ended.-------Hope this helped =-)

1. On August 6, 1945 Hiroshima was the primary target cityof the Little Boy enriched uranium atomic bomb and the bomb was dropped there.
2. On August 9, 1945 Kokura was the primary target city of the Fatman plutonium atomic bomb, however due to heavy smoke cover from a nearby city that had been firebombed the night before it was not possible for the bombardier to identify the aim point and it was decided to proceed to the secondary target.
3. On August 9, 1945 Nagasaki was the secondary target cityof the Fatman plutonium atomic bomb and the bomb was dropped there, despite heavy cloud cover making it difficult for the bombardier to identify the aim point (as it was the bombardier identified the wrong point, resulting in the Fatman being dropped about 1.9 miles from the planned aim point). The aircraft did not have enough fuel left to consider proceeding to the tertiary target city.

It depends on how many kilotons the bomb has which is pretty much literally its destructive power. The atomic bomb dropped on Hiroshima during World WarII was called little boy and had either 25, 30, or 35 kilotons(sorry i can't remember the exact amount) and reached about 0.5 or 1 mile from where it was dropped in all directions. Little boy was the first atomic bomb ever used. Hope this answers your question correctly =)

On August 6, 1945 the nuclear weapon Little Boy was dropped on Hiroshima ,directly killing 80,000 people and completely destroying approximately 68% of the city's buildings.an estimated 60,000 more people died from injuries or radiation poisoning.

The two cities of Japan which were hit by the atomic bomb by America were "NAGASAKI" and "HIROSHIMA".

The bomb was initially designed to be used against Nazi Germany, largely because it was feared that Hitler was developing a nuclear weapon of his own (as indeed he was, although Nazi development of the H-Bomb was not as far advanced as the Allies believed). The original target was thus to have been Berlin, but the War in Europe ended without this becoming necessary. However, the Japanese fought on in the Far East, and it was known that they would not surrender without drastic action (in Japan, surrender to an enemy is considered to be a huge disgrace. Most Japanese soldiers preferred to die rather than surrender, and many committed suicide rather than face capture). The Pentagon estimated that a conventional invasion of Japan would cost over 1 million Allied servicemen's lives, and had a choice of this or the use of the newly-developed A-Bomb. They chose the latter option.

The previous answer is absolutely correct, tactically speaking. Technically speaking the first target of the atomic bomb was the desert of Alamogordo, New Mexico, the Trinity site. At 5:29:45 a.m. Mountain War Time on 16 July 1945, the first atomic weapon was detonated atop a 100 foot tower. The site was declared a national landmark in 1975, and is now open for tours.

It's because Japan thought they could beat us. Japan conquered a large part of Asia and the Pacific to secure the nature resources and land which their country lacks. By pushing western interests out of the region, they could secure their empire and join the ranks of world super powers. Considering things like general Yamamoto's plan to attack the Panama canal, the Japanese were an extremely formidable side to face.

The U.S. dropped both atomic bombs in the year 1945. The first one was launched on the 6th of August and hit Hiroshima. The second was launched three days later on the 9th of August and hit Nagasaki.

Atomic bombs contain material capable of undergoing fission. Fission is a process whereby the nuclei of large unstable elements such as plutonium or uranium split into two smaller daughter nuclei, converting some of their mass to energy, which results in a large amount of heat. Fission naturally occurs in all samples of material capable of undergoing it, but it is the rate which allows heat to be released in a controlled manner, as in a nuclear reactor, or in the runaway explosion of a nuclear bomb.

The unstable nuclei which undergo fission are not normally present in high numbers in the radioactive material, due to their quick decay into daughter nuclei. Instead, they are created by the collision of a free neutron with a more stable nucleus, such as U-235. The now slightly larger nucleus (in this example U-236), rapidly undergoes fission, forming daughter products, giving off energy and releasing 3 more neutrons. These neutrons can then go on to hit further U-235 atoms and cause further fission, in a process known as a chain reaction. Although theoretically this means that the reaction will proceed at a faster and faster rate as more and more neutrons are released, in most cases the concentrations of U-235 atoms are low enough that most neutrons do not go on to collide with them and allow the reaction to proliferate. However, if U-235 is present in sufficient concentrations, and at a sufficient (critical) mass, then enough neutrons will be absorbed that once started the reaction will rapidly proceed to completion, releasing vast amounts of energy. This explains the importance of enriching Uranium (increasing the ratio of U-235 to U-238, which does not undergo fission). If Uranium is slightly enriched, then it can provide a suitable fuel for nuclear power stations, able to continue a fission reaction without letting it run out of control. However, if it is highly enriched (around 80% U-235), then the initiation of a fission reaction will result in a rapid runaway chain reaction releasing huge amounts of energy - the explosion.

This presents a problem, as the material must be enriched in advance of preparing the device. The material must therefore be arranged in the device in such a way that it does not allow a reaction to begin until some change is brought about to make it achieve a critical mass on detonation. For example, the Hiroshima bomb was made of 2 sections of fissile material, neither of which had a critical mass by itself. On detonation, a conventional explosive fired one section into the other section, causing the now larger sample of material to obtain a critical mass and undergo a chain reaction.

"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.

July 16, 1945 the first atom bomb called "Gadget" was tested in New Mexico near Alamagordo.

See: Atomic bombing of Hiroshima and Nagasaki.

The first atomic detonation was at Los Alamos National Laboratory in Los Alamos, New Mexico. This was for testing purposes.

The first city to be attacked with an atomic bomb as an act of warfare was Hiroshima, Japan. It was bombed on August 6, 1945 by American forces.

Harry S. Truman, the 32nd President of the United States of America, gave the order to drop the atomic bombs "Little Boy" and "Fat Man" on Hiroshima and Nagasaki, both major cities in Japan. That order was relayed by the War Department on July 25, 1945, only nine days after the "Fat Man" type bomb was successfully tested at Alamagordo, New Mexico, and one day before the "Potsdam Proclamation". "Little Boy" was dropped on Hiroshima on August 6, 1945, and "Fat Man" was dropped on Nagasaki on August 9, 1945.

After hard-line factions in the Japanese government tried to keep the war going, Emperor Hirohito of Japan formally surrendered in a public address on August 15, 1945, ending the war between the U.S.A. and Japan.

The first atomic bomb dropped on Japan was dropped on Hiroshima.

A second bomb later was used against Nagasaki, after no response from the Japanese.

There is also the Trinity test, which was a test to see if it would explode in the force it was supposed to, and that was in New Mexico.

J. Robert Oppenheimer allowed for the fact that such a bomb existed as far back as May 10th, 1945. Remember that the Manhattan Project was undertaken using the utmost secrecy. The atomic bomb was first exploded at the top secret base of Alamogordo, NM on July 16th, 1945. The bomb was first used in warfare at Hiroshima and Nagasaki, Japan in August 1945. .

The Manhattan Project was the codename for a project conducted during World War II to develop the first atomic bomb. A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion.

Project research took place at over thirty sites across the United States, Canada, and the United Kingdom. The three primary research and production sites of the project were the plutonium-production facility at what is now the Hanford Site, the uranium-enrichment facilities at Oak Ridge, Tennessee, and the weapons research and design laboratory now known as Los Alamos National Laboratory.
