One problem with gallium involves nuclear weapons and pollution. Gallium is used to hold some nuclear bomb pits together. However, when the pits are cut and plutonium powder is formed, the gallium remains in the plutonium. The plutonium then becomes worthless in fuel because the gallium is destructible to several other elements. If the gallium is removed, however, the plutonium then gets it’s worth back again.
The problem is that the process to remove the gallium contributes to a huge amount of pollution of water with radioactive substances. Gallium is an ideal element to use in the bomb pits, but pollution is harmful to the earth and to the health of its people. Even if efforts were taken to remove the pollution from the water, it would considerably increase the costs of the procedure of turning plutonium into a fuel by about 200 million dollars. Scientists are working on another way to clean the plutonium, but it could take centuries to be completed.
For decades, Harry Truman, the 33rd President of the United States of America, will always be remembered as the man who took the decision to launch the atomic bomb in two cities of Japan, Hiroshima and Nagasaki in 1945. The president takes measure, which was a very important decision and any President would ever have to make. Harry Truman, the 33rd President of the United States, is known for the decision to drop the bomb in Japan in August 1945.
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
Radioactive Waste One of the most talked about opposition to nuclear fission is the radioactive waste it produces. Radioactive waste is what is left behind after using a reactor to make electricity. There are two levels of waste, low and high, but both are regulated by the Department of Energy and the Nuclear Regulatory Commission. High level waste is made up of fuel that’s been used directly in the reactor, which is highly radioactive but can still be disposed of. Low-level waste is the contaminated items that have been exposed to radiation.
“The atomic bomb certainly is the most powerful of all weapons, but it is conclusively powerful and effective only in the hands of the nation which controls the sky” (Johnson 1). Throughout World War II, the war was in pieces. The Germans were almost at world domination along with their allies, the Italians and Japanese. The Japanese and United states had remained at combat with each other since the bombarding of the Pearl Harbor ("U.S. Drops Atomic Bomb on Japan "1). There was abundant controversy as to whether the United States should have used the atomic bombs or not. There were many factors as to the argument relating to the atomic bombs leading to the United States final decision. Many people had arguments for the bombing and others had arguments against the bombings but it is still not determined if the United States made the right decision.
The morning of the atomic bombings on Hiroshima and Nagasaki were like any other morning in Hiroshima, the air raid warnings went off at about 7am and ended at about 8am. With not a plane in site they got the all clear, at least that’s what was thought. America dropped one of the biggest atomic bombs made at the time right on Hiroshima, since the bomb the people and town of Hiroshima and Nagasaki have never been the same. After the bombing in Hiroshima the survivors had to go about their lives and move on from all the destruction brought upon them. Some survivors though, showed hatred and anti American feelings towards the situation because all the grief and devastation that had been done. While other survivors didn’t show that
“With this bomb we have now added a new and revolutionary increase in destruction to supplement the growing power of our armed forces”- President Truman. In the 1945, President Truman was faced with an atomic dilemma in the most destructive war that mankind has seen so far. His choices were to either bomb Japan or let more American soldiers die. He chose to bomb Hiroshima and Nagasaki. He chose the most likeable choice in America at the time. If I was able to tell President Truman one thing, it would be, drop the atomic bombs on Japan and end the four year war for America. Japan started the war on America with the bombing of Pearl Harbor, America repaid the debt back to Japan many fold(top secret).
Near the end of the Second World War, America and Japan continue to fight with no signs of surrender in sight from either side. President Truman warned the government of Japan that he would use weapons of mass destruction if there was not an end to the war, but they refused to surrender. The decision that Japan made to ignore President Truman left him with two choices; develop the atomic bomb or invade Japan with American forces and allies. After careful consideration, President Truman made the choice to develop and use the nuclear bombs as a way to end World War II. On August 6, 1945, the president unleashed the massive weapon of destruction on the city of Hiroshima dropping the atomic bomb code named “Little Boy”. A few days later on August
On August 6, 1945, the first bomb was dropped on the city of Hiroshima. Three days later on August 9, the second bomb hit Nagasaki. Whether the United States made a moral and ethical decision is still an ongoing debate. President Truman was faced with a difficult choice. The U.S. chose to adopt a stance that seemed to limit the amount of casualties in the war, by significantly shortening it with the use of atomic weapons. It was certainly a reasonable view for the USA to take, since they had suffered the loss of more than thousands of lives, both military and civilian. To the top rank of the US military the death toll was worth it to prevent the “many thousands of American troops that would have been killed in invading Japan.” This was a grave
On August sixth 1945, 8:15 AM, the first successful atomic bomb attack was dropped on Hiroshima, Japan. Due to Canada’s involvement in the making of this destructive weapon, many peoples' perspective on Canada has changed for the worse.
The Big Bang The opportunity to end World War II was right in front of President Truman, but could he unleash the horrible weapon against Japan? Would he be able to use the weapon that was likely to be the most destructive weapon ever used? President Truman’s goal was to end the war as swiftly as possible, and with the atomic bomb, he would be able to accomplish this goal. President Truman believed the atomic bomb would save both American and Japanese lives.
After the first few days of the bombings of Hiroshima and Nagasaki Americans, without knowledge of the aftermath of these cities, began cheering and celebrating as the bombings marked the end of World War II. Also, this event showed that Americans would be the ones who would lead the world into the nuclear age. In a Gallup Poll taken from August 10-15, 1945, Americans were asked whether or not they approved or disapproved of the use of atomic bombs on Japanese cities, 85 percent approved, ten percent disapproved and five had no opinion.30 then when asked if the development of the atomic bomb was a good or bad thing, 69 percent said it was a good thing, 17 percent said it was bad, and 14 percent had no opinion (Steele).
Since the dawn of civilization, all living (and some non-living) things have needed energy. When humans discovered fire, the first form of harnessed energy, it made it easier to stay warm, prepare food, make weapons, etc. Since then, humankind has been inventing new ways to harness energy and use it to our advantage. Now-a-days, people in most nations depend extremely heavily on fossil fuels – to work, travel, regulate temperature of homes, produce food, clothing, and furniture, as well as other power industries. Not only are these fossil fuels dominating our society and creating economic vulnerability, but they also produce waste that causes a number of social and environmental concerns. The waste from these fuels leads to acid rain, smog, and climate change. It also releases sulfur dioxide as well as other air pollutants that are very harmful to the human respiratory system (Morris, 1999, p. ix). There are other alternative sustainable energy sources including solar, hydroelectric, wind, and biomass. However, the main source aside from fossil fuel is nuclear energy from controlled nuclear reactions (where nuclei of radioisotopes become stable or nonradioactive by undergoing changes) in a nuclear power plant. Nuclear power produces enormous amounts of energy to serve a community. Unfortunately, nuclear energy has its own set of problems – a big one being its waste. The spent fuel from nuclear plants is radioactive. This means that it emits radiation, or penetrating rays and particles emitted by a radioactive source. Ionizing radiation is known to cause cancer, and therefore makes anyone who lives near spent nuclear waste facilities vulnerable to this incurable disease. The disposal of nuclear waste is a global issue...
In addition to the potential dangers of accidents in generating stations, nuclear waste is a continuing problem that is growing exponentially. Nuclear waste can remain radioactive for about 600 years and disposing these wastes or storing them is an immense problem. Everyone wants the energy generated by power plants, but no one wants to take responsibility for the waste. Thus far, it is stored deep in the earth, but these storage areas are potentially dangerous and will eventually run out. Some have suggested sending the waste into space, but no one is sure of the repercussions.
As one of the greatest alternatives to fossil fuels, an important advantage of nuclear energy is the significantly lower emission rate of CO2 in comparison to plants which use coal and natural gas.2 Nuclear power is not reliant on fossil fuels and therefore producing energy by this method reduces pollution and the contribution to climate change. However, whilst the actual process of generating energy releases few emissions, uranium must be mined and purified and in the past this has not always been an environmentally clean process.2 Ultimately, uranium will one day run out, but nuclear reactors are versatile and may also run on Thorium. Despite being finite, this would allow nuclear power stations to function for a longer period of time.
