Tc-99m is mostly a manmade substance. However, Tc-99m can be found in a few places throughout the environment. The few places that Tc-99m can be found is after detonation of nuclear weapon, airborne emissions from a nuclear reactor, airborne emissions from a nuclear fuel reprocessing plant, and the storage of radioactive waste in a facility, or a facility that treats radioactive waste. Since there are few places that produce Tc-99m there is a high need for the substance and is therefore manmade to keep up quantity.…
In January 1950 president Truman made the decision to continue the research and development of thermonuclear weapons. He wrote a letter to Crawford H. Greenewalt asking him to take charge of overseeing the designs, construction, and operation of the new site to produce plutonium. They set up distant sites across the country and ended up having operations in 32 states.…
With the end of World War 2 came the Cold war with many controversies even between former allies. Communist Russia forced control over their section that was gained in the Potsdam conference. They set up many barriers around their portion of East Berlin and eventually around East Germany. America had dropped the Atomic Bomb on Hiroshima and a new technology been revealed as a massive, deadly weapon that could wipe out thousands instantly, it was now an arms race. “Push of a button in Russia, and 35 minutes later much of U.S. could be laid to waste—with power to retaliate limited.” (Document E)…
U.S. President Harry S. Truman publicly announced his decision to support the development of the hydrogen bomb, a weapon theorized to be hundreds of times more powerful than the atomic bombs dropped on Japan during World War II. He approved of the funding for the nuclear weapon because of several events prior to his public announcement. One of the reasons was the fact that the United States had lost its nuclear supremacy when the Soviet Union successfully detonated an atomic bomb at their test site in Kazakhstan in 1949. Another reason why he decided to fund experiments for nuclear weapons is because the British and U.S. intelligence discovered that Klaus Fuchs, a top-ranking scientist in the U.S. nuclear program, was a spy for the Soviet Union.…
Her father, Sebastian Hinton, was a lawyer (who also was the inventor of the jungle gym); her mother, Carmelita Hinton, was an educator and the founder of The Putney School, an independent progressive school in Vermont. Her sister, Jean Hinton Rosner (1917–2002), was a civil rights and peace activist. Joan Hinton's great-grandfather was the mathematician George Boole; Ethel Lilian Voynich, a great-aunt, was the author of The Gadfly.…
The only military use of atomic weapons has been on the Japanese cities of Hiroshima and Nagasaki and almost certainly brought a prompt conclusion to WW2. However, the question of whether it was necessary is still hotly debated 70 years after the event. The answer is no it wasn’t necessary, although it is not as simple as you may think because if I had just been a soldier fighting in New Guinea or if I was a POW starving on the Thai-Burma railway [1] then answer is yes it was necessary. Necessary can have various meanings though such as indispensable or requisite, but also mean acting from need. The question becomes very problematic or ambiguous if one uses both meanings as again we get a yes and no.…
From the mid 1940’s through the mid 1960’s, the United States was in its first cold war with the Soviet Union. It was considered cold because there was no outright fighting. The U.S. had been fighting to rid the world of communism, but only brought the communist USSR and USA together to fight their common enemy, Germany in World War two. The United States made a deal with the USSR that once Germany surrendered, ninety days after that they would declare war on Japan. The US had developed a nuclear bomb that would eventually lead to be the winning weapon of world war two.…
In Europe, the war with Germany was over but Japan was still fighting. So the U.S could concreted on the war with Japan. The U.S had atomic bombs ready and a decision had to be made; should they sent ground forces to invade Japan or should they bomb Japan. So on August 1945 the U.S decided to drop atomic bombs on the Japanese cities of Hiroshima and Nagasaki and this created some controversy. Some people though it was a good idea to bomb Japan, while others say that 200,000 innocent people were killed. I believe that bombing the two cities was the right decision because it did save the lives of many U.S soldiers and it ended World War II.…
As World War II was coming to an end during 1945, the creation of one of the most destructive weapons known to humanity occurred within the United States. This weapon, known as “the atomic bomb,” was used on the two Japanese cities: Hiroshima and Nagasaki, resulting in a death toll unprecedented by any military weapon used before and an immediate, unconditional surrender. Some historians believe President Truman decided to drop the atomic bomb in order to intimidate the Soviet Union whereas others believe it was a strictly military measure designed to force Japan’s unconditional surrender. In the Report of a Scientific Panel of nuclear physicists, some scientific colleagues believed the atomic bomb was a “purely technical demonstration” to induce surrender. Other scientists believed that the use of the atomic bomb will improve international prospects in that they are more concerned with the prevention of war than with the elimination of this special weapon (Doc G). Thus, the United States dropped the atomic bomb to both force Japan’s unconditional surrender and to intimidate the Soviet Union.…
The United States dropping on atomic bomb on Hiroshima was one of the most controversial topics of 1945. Many believe that the United States decision to drop this atomic bomb on Hiroshima, was a diplomatic measure intended to scare the Soviet Union after the Second World War; however, this is untrue. The United States decision to drop the atomic bomb on Hiroshima was done entirely to scare the Japanese army, and force them to surrender.…
Manti Te’o once said “Things happen. And good things happen, and bad things happen. And I'm a person - I'm a believer that everything happens for a reason”. When president Truman and his advisors made the decision to drop the atomic bomb, they thought it would end the war. The dropping of the atomic atomic bomb had many successful tactics. It created great peace for the US from the fact that it ended total war. After the US had lost millions to the war, it was ready to make a change to end all war. Good things did come from the atomic bomb, like the fact that it ended World War II.…
In 1945 Harry S. Truman decided to use the atomic bomb not only once, but twice to finish World War Two. The first bomb that was dropped on Hiroshima August, 6th killed upwards to around 80,000 people and the second bomb dropped on Nagasaki August, 14th killed 40,000 people. The controversy of the atomic bomb is because of the amount of innocent people that were killed in Japan. Nobody will ever know the outcome of the war if we never dropped the bomb, but we do know that the war was ended because of it. Over 100,000 people lost their lives because of these bombs, but how many lives would have been lost if we never dropped them? That is the other question that can never be answered, but based…
During the Cold War, Americans lived in a society where the tension between the Soviet Union was at its peak in history. It was a time when the hatred against communism and the idea of nationalism were growing exponentially. Meanwhile, Julius and Ethel Rosenberg were arrested for the accusations of helping the Soviets create the atomic bomb, which was the United States’ only advantage over the Soviets. Their arrest eventually led to the first ever execution of espionage in United States history. However, the justification of their execution is still being debated to this day. Did the Rosenbergs deserve such a harsh sentence or was it a misjudgment driven by the fear of communism? The political and social aspects of society certainly directed…
Atomic bombs have killed up to 80,000 people in an instant when dropped. During the Cold War many countries built more nuclear weapons. Communism and the creation of nuclear weapons were two major problems during the Cold War. The Soviet Union and The United States were allies during WW2 but soon turned against each other after the resolution of the war in 1945. The Cold War then lasted approximately 45 years, when becoming obvious in 1947 and then ending in about 1991.…
Robert Oppenheimer and thousands of other intelligent scientists worked on the development of the world’s first nuclear weapon, that was used to bomb the Japanese cities of Hiroshima and Nagasaki, ending the World War Two. Soon after Japan's surrender, Oppenheimer was called into President Truman's office to discuss how the scientists and military could continue working together to make more atomic bombs. Oppenheimer tried to change the subject to international cooperation and trying to stop the arms race before it began. This was the complete opposite of Truman's wishes. Oppenheimer proceeded to say things such as,” I have blood on my hands,” which made sure that Truman would never want to see his face again. Oppenheimer made a decision based…
