From its time of discovery in 1941 Plutonium has been both beneficial and detrimental to the human race. The isotope most detrimental is Plutonium-239 which has been used to create nuclear weapons. Plutonium-239 was used in the atomic bomb codenamed “Fat Man” that was dropped on Nagasaki during World War II. Normally a nuclear bomb uses 10 kilograms of Plutonium, but “Fat Man” used even less and still caused a lot of destruction. To put it in perspective again just 1 kilogram of Plutonium-239 causes an explosion equal to that of 20,000 tons of TNT. The way Plutonium-239 works in an atomic bomb is it is controlled by explosives until it goes critical and cause a fission chain reaction. When this happens all the energy is released causing a nuclear explosion. In comparison to other isotopes of Plutonium, Plutonium-239 has been more detrimental than beneficial to the human race. …show more content…
This isotope is useful because of its high heat density that is constant and reliable. The heat output only reduces after the 88-year half-life of the isotope. This half-life makes it a good heat source and even after one half-life it still gives out enough heat that is useable. If you were to come in contact with Plutonium-238, then it will feel warm to the touch because of the high heat output. Plutonium-238 has been recorded at given out 22 million kilowatt hours of heat. That is why it is popular as a heat and power source in the space program. Spacecraft are using these thermoelectric generators which convert the heat from the Plutonium to energy that powers that spacecraft. Plutonium is also used in heater units to heat the area inside the spacecraft and allow it to work even in the frigid temperatures of deep space. Also the alpha particles that come off of the Plutonium can easy be stopped making it safe to use on manned
On August 6, 1945, the U.S. dropped the world’s first atomic bomb over Hiroshima. Three days later, a second bomb was dropped on Nagasaki. On August 15th, the Japan announced unconditional surrender in World War II. To this day historians still discuss why the U.S. decided to use the atomic bombs. Orthodox historians argue that the decision to drop the bombs was a military one designed purely to defeat the Japanese. Revisionist historians argue that the bombs were not needed to defeat Japan; the bombs were meant to shape the peace by intimidating the Soviets. After analyzing the documents in The Manhattan Project it has become clear that the U.S. used the bombs during WWII not only to defeat the Japanese, but also to intimidate the Soviet Union
Decisions are the hardest thing to do, especially considering how Harry Truman decided to drop the US Atomic bombs onto Okinawa and Iwo Jima. The role to end the war with Japan was in his hands, but it would require releasing the most horrendous weapon ever known. Although, there was some controversy over Truman’s decision. Some people say that it was unnecessary to use the Atomic bombs, such as the Federal Council of Churches and the Christian Faith. They stated that: “As American Christians, we are deeply penitent for the irresponsible use already made of the atomic bomb. We are agreed that, whatever be one’s judgment of the war in principle, the surprise bombings of Hiroshima and Nagasaki are morally indefensible. ("8 Primary Pros and Cons of Dropping the Atomic Bomb")” People also
The creation of the hydrogen bomb, moreover the summoning of an arms race, spawned worldwide desire for nuclear arms, and worldwide fear for those who had them; The effects of such can be seen in the economic and diplomatic benefits exhibited by those with enough stamina and vigilance to endure its costs, and in the extreme measures taken by countries, nominally the United States, to respond to the security threat posed when other countries owned the bomb. Furthermore: For those whose economy could afford it, nominally the U.S., USSR and India, economic and diplomatic benefits followed its creation; For the U.S., following the creation of the bomb by enemies were extreme defense tactics; For all the benefits and costs compelled a worldwide
Plutonium, which is a byproduct of the fission process, can also be used for manufacturing weapons and only requires 2-10kg to develop weapons. The atom bomb that landed in Nagasaki contained plutonium fuel. Depleted uranium, which is the left over from the enrichment process, is used to make military grade armor piercing bullets. These DU penetrators have been used in wars throughout history, the most recent being the Gulf wars. This is a disadvantage because the depleted uranium is toxic and has been scientifically proven to cause birth defects, cancer, and death where it was used.
During World War II, a new, powerful, and top-secret weapon of mass destruction was necessary in order to defeat Hitler and Germany. This weapon was the Atomic Bomb, these bombs were controversial due to it 's sheer power to decimate an entire city, and kill possibly millions after it was tested. It 's name was Trinity in 1945. Let us rewind back three years when Nazi Germany was a strong force to be dealt with. There were fears and discussions about Nazi Germany was possibly developing and building a nuclear weapon during WWII. This fearfulness triggered President Franklin Delano Roosevelt to assemble a crew of top-secret scientist which even included the assistance of Albert Einstein.
One of the most controversial decisions that have been made, in the history of the United States, was Harry Truman’s decision to drop atomic bombs on the two Japanese cities of Hiroshima and Nagasaki. The ever so controversial topic of the dropping of the atomic bombs has successfully driven people insane. People feel strongly that this decision was atrocious and unnecessary, while others believe the polar opposite, that it was completely necessary. Some historians argue that the human cost to the Japanese population can never justify the use of such weapons. Other historians see it from an optimistic perspective, that it would not have been moral if atomic weapons had not been used to end the war as quickly as possible. President Harry S.
The gravity of the atomic bombings was not taken lightly by the nations surrounding Japan, but the United States refused to lose any more men in a long-winded assault; the enemy 's resolve was unmatched by American standards. Majerus states, "This firm resolution of the Imperial Army to fight out an all-or-nothing battle until virtually the very last man ultimately did not go unnoticed by US government officials." (5). Further proofs of these arguments were demonstrated by the Japanese when they deployed the kamikaze (suicide pilots) to Pearl Harbor. The raising question is, however, did decisional certainty regard any ulterior motive at the time considered to prevent the death of American troops, or had there been any considered possibilities within a peaceful resolution? This has sparked another theory among the nation 's scholars. Did the U.S. drop the bombs to save American lives, or to intimidate their rivaling ally, the Soviet Union? It was later revealed that the USSR was willing to help the United States in the assault of Japan. History teacher Brent Dyck states, "At the Potsdam Conference held in July 1945, Stalin told Truman that the Soviet Union was ready to help the United States and invade Japan on August 15."
The fact that the United States resolved to drop an atomic bomb over Hiroshima and Nagasaki, Japan shocked many people, including U.S. citizens. The U.S. chose a brutal weapon when choosing the atomic bomb, as proven by the thousands of deaths it caused. Today, some people still question the motives for such a ruthless choice of weaponry. The atomic bomb, however destructive and questionable, seemed to be the only way to ensure “unconditional surrender” of the Japanese. The atomic bomb was, in fact, “a clear step designated to force Japan’s unconditional surrender;” however, this statement fails to give attention to the larger picture that influenced the U.S.’s decision to use the atomic bomb. By using the atomic bomb before any other nation
...nce World War II to the present day, the technology of nuclear power has increased significantly in terms of energy output and safety. The energy efficiency of nuclear power is far superior to its counterpart fossil fuel and renewable energy. Compared to fossil fuels, tiny amounts of fuel used by nuclear reactors is equivalent to a large sum of coal. This is a no brainer. Why mine a ton of coal when a little uranium can be used to gain the same amount of energy? Not only is it efficient, it’s safe to use. Used fuel is packed away in storage safely, so there isn’t any chance of radiation leaking out. In the present day, nuclear power incidents haven’t been occurring lately. Advancements in technology and equipment used have made nuclear energy a very reliable and safe source of energy. With today’s energy needs, nuclear power has the ability to keep up in the race.
As with everything, problems occurred during the development process. The plutonium needed for the bombs was only in microscopic sizes, which was very difficult to handle. Plutonium’s properties were unknown, and scientists knew very little about uranium 235. The plants needed to be run by machinery because the materials were “radioactive, poisonous, violently corrosive, or all three” (Gerdes 143).
Nuclear energy has is an overall success and continues to be because it is a reliable, efficient energy source that produces minimal pollution. Although it is a efficient energy source, it is also a massive destructive force that has been used in the past and can be used in the future if not properly defended against. America today can learn from instances in the 20th century such as the atomic bomb drops, exploration of fusion reactions, the knowledge gained from the three mile island accident, and from espionage. Nuclear technology is basically that manipulation of atoms in their current state. Usually radioactive elements such as high-grade plutonium or uranium are used in order to create a massive radioactive reaction that have the potential to obliterate any object in its way leaving a lasting negative effect on the environment. Nuclear energy was mainly researched for the atomic bomb droppings that occurred in 1945 as a result of Japanese oppression during World War II. The science of atomic manipulation, atomic radiation, nuclear fission and nuclear fusion was first developed in 1895. Research began to significantly speed up when the government took a large interest in the destructive force that nuclear weapons had the potential to hold. The only reason that the world ever had the experience of nuclear energy was because of World War II and oppression. Nuclear Energy came with a price of thousands of lives, that were not rightfully taken, but without those lives lost, our world would be different today, and we continue to learn from the mistakes and from the successes that we have had with nuclear technology.
In 1945, when the Americans bombed Hiroshima, Japan, approximately 140,000 men and women were instantly killed by the effects of American nuclear defense. With such extreme brutality and force how many people must die for one to finally realize the strengths of nuclear bombs and what damage they can cause. Nuclear weapons should be outlawed because they kill thousands of innocent humans at a time, destroy the environment, and inviolate human’s right to moral and personal freedoms.
The use of nuclear energy has increased in the United States since 1973. Nuclear energy's share of U.S. electricity generation has grown from 4 percent in 1973 to 19 percent in 1998. This is excellent news for the environment. Nuclear energy and hydropower are the cleanest large-scale means of electricity production. Since nuclear power plants do not burn fuel, they emit no combustion byproducts—like carbon dioxide—into the atmosphere (www.nei.org). Nuclear power can come from the fission of Uranium, plutonium or thorium or the fusion of hydrogen into helium. Today uranium (U-235 and U-238) is most commonly used in the production of nuclear energy. The expa...
New inventions are created daily; however, it is those that truly change the world that are remembered. The use and discovery of atomic energy negatively impacts the world because of the danger it entails. Many people across the world believe that the use of atomic energy is a mistake based off of past events that have occurred such as the bombings at Hiroshima and Nagasaki. The abuse of atomic energy has been proven to damage society’s morale, population and could potentially destroy entire populations.
