Atomic Bombs

In 1939, J. Robert Oppenheimer was the first to realize that an atomic bomb could be made as a result of nuclear fission. Prior to this, there were several scientists around the world who knew they were on the verge of discovery. It wasn't until 1945 that the first experiment was conducted.

Effects of the explosions and radiation When the bomb exploded metal, stone and clay tiles melted by the extreme heat. As the heat wave struck, people disintegrated and their shadows were outlined on the streets. If the people looked at the explosions their eyes would be burned. People that survived the explosions had their hair fall out, severe burns, infertility, leukemia, cancer, birth defects, nausea, vomiting, diarrhea, cataracts, loss of blood cells

NO ONE dropped the A-bomb in anger! The US President wanted a decisive show of force to end WW2 and to force Japan to surrender. The objective was to save lives of soldiers fighting the war on both sides, even at the cost of civilian lives.

Now that we know the devastation nuclear fission causes to humans, it is very unlikely any sane leader would use nuclear weapons... but not all leaders may be as sane as others.

Japan, there were no other enemies left.

It is not , if it is not detonated and it is properly maintained.

Noplace, the US did not have any atomic bombs in 1944. Nobody had atomic bombs in 1944.

Yes. You ask any living warrior from World War 2 and any offspring of those men and you will learn they are extremely grateful the atomic bombs motivated Emperor Hirohito to finally surrender. There are Japanese from that era who could tell you they were so relieved the war finally ended even though they hate the way it was ended and what happened to their people.

The US detonates a uranium bomb over the Japanese city of Hiroshima, killing more than 140,000 people within months. Many more later die from radiation-related illnesses. The US explodes a plutonium bomb over Nagasaki. An estimated 74,000 people die by the end of 1945. Little can be done to ease the suffering of the victims who survive the blast.

None if directly exposed to thermal flash or blast.

Almost any if only exposed to the radiation. The LD50 for ionizing radiation is much higher in insects than it is in mammals.

No, the people apart of the Manhattan Project did.

Someone said that war was the biggest business and most likely he was talking truth.

If what you mean is,is an atomic bomb stronger or weaker then a regular bomb then it's the atomic bomb,a regular bomb would have only damaged Hiroshima not completely killed it( the U.S also bomb Nagasaki)

Of 4 MeV.

i.e., 4Mega electron Volt

There is still a little bit of radiation. Just after the war, people were still dying from radiation. The bombs they used were very powerful and used a considerable amount of radiation. Even five years after the war, the radiation was so heavy that your chances of getting cancer was raised by thirty percent. I'm not sure if there is radiation in the SOIL, but there may be some still around.

A number of people in Hiroshima and Nagasaki did survive the atomic blasts but naturally they were not at the centre of the detonations.

A written warning to Japan with options.

Not many really. Japan had bombed the territory of the United States in an attempt to put the entire Pacific ocean under the control of the Japanese Emperor. As such, the Emperor and his military had to be NOT JUST STOPPED, but also prevented from ever making such an attempt again. The war had been won, but the Emperor refused to surrender and sign an agreement to stop the aggression. Japan had been surrounded, the Japanese navy had been destroyed, the Japanese people were starving and there was no possibility of getting resources to prevent the death of their people. The emperor was willing to let millions die rather than surrender. The emperor felt that the Allied forces could not endure the killing of so many people, so the Japanese citizens had been given sharpened sticks, axes, pitchforks and anything else that might cause harm, and they were told to defend the shores of Japan against invasion. Many millions of innocent citizens would have been killed and were already dying from disease and malnutrition, and still the Emperor refused to surrender. Manufacturing centers were bombed using conventional bombs causing wildfires that burned entire cities and killed hundreds of thousands every time we tried to convince them to surrender. Truman claims that he warned the Japanese that he had a weapon of incredible power and gave a time limit to the surrender, but there is no evidence that this actually occured. When the bomb was dropped on Hiroshima, Japan was stunned, but the Emperor still refused to surrender. Truman told him that we have more, but the Emperor still refused to surrender. When the bomb was dropped on Nagasaki, the Emperor finally agreed. In reality, the Emperor wanted the option to regroup and still take on the islands of the pacific and surrender prevented that option. No, there weren't very many options. Estimates were that had the Allied forces invaded Japan in a conventional way, we would have lost as many as a million soldiers, and possibly more. Yes, we would have eventually won, but here is a thought for you to consider. Imagine that your father, brother or uncle or possibly even two or three of your loved ones had been killed trying to stop someone who had attacked your nation. Then imagine how you would feel if you found out that your nations President had a weapon that would have stopped the war and your father, brother, uncle or neighbor died for absolutely no reason. That the war could have been stopped and OUR people did not need to die. How would you have felt? There were alternate plans to droping the atomic bomb. One plan was a diplomatic approch where if Japan surrendered the US would let them keep their "sacred emperor". The emperor was considered a god in Japan. The Japanese people were fighting so hard to the bitter end because they did not want to US to take their emperor away from them. Another plan to end the war involved Russia. If Russia would join the US in the invasion of the mainland the extra man power could be enough to defeat Japan without as many casualties. At the Potsdam conference in Berlin Russia agreed to help the US. But Truman, being pressured by those around him, chose to use the atmoic bomb.

Yes. New Mexico during the predawn hours of July 16, 1945. was where the first atomic bomb was tested.

JR Oppenheimer

The US dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki during World War II. The first bomb was used on August 5, 1945. The second was dropped on Nagasaki on August 9, 1945 -- mainly to prove that the Hiroshima attack was indeed an incredibly devastating new weapon that could and would be used again. (The US was still building its fourth and fifth bombs.)

At Hiroshima, the bomb exploded 2,000 feet from the ground to increase the damage from the blast wave. But it was a firestorm from the city's burning structures that killed many of the residents who survived the blast itself.

In Nagasaki, a lower detonation height and an aiming error meant that several areas of the city were shielded by the intervening hills.

Harriet Tubman wasn't president, Harry Truman was.

Reasons why he used the atomic bomb are debated. Some speculate that it was because it cost a lot to make and that was enough reason; others believe that he was using it as retaliation for Pearl Harbor. Many believe that Truman was convinced dropping the bomb would force Japan to surrender, but others say that Japan would have surrendered soon even without it. It's not clear exactly why he used it, and it's possible that it was a little bit of everything

This must refer to radiation sickness, which is caused by exposure to high doses of radiation. It can begin with minor bleeding and more exposure will cause hair to fall out and failure of organs.
