Uranium

Uranium was first discovered in 1789 by Martin Klaproth. It was formed in supernovas about 6.6 billion years ago. Uranium is one of the heavier elements on the periodic table, being 18.7 times as dense as water. It is element number 92 and this specific isotope has 235 nucleons. This indicates to us that Uranium 235 has 92 protons, 92 electrons, and 143 neutrons. Uranium’s slow radioactive decay is the main source of heat inside the earth, causing convection and continental drift. Uranium 235 is the only naturally occurring fissionable fuel (can sustain a chain reaction) in the world. U-235 is special because it can readily split, which would create a lot of energy. It is called ‘fissile’. When the nucleus of U-235 atoms captures a neutron, it splits in two. This causes a release in energy in the form of heat, as well as 2 to 3 neutrons being thrown off. Nuclear factories use Uranium 235 as their main source of fuel. The heat given off by the fuel is used to…

How Uranium affects TP53 Do we know how Uranium affects TP53 to affect our bodies? Uranium is a dense radioactive metal, that is used as fuel in nuclear reactors. Uranium has several isotopes, and the most important of these, are radioactive and presented in nature. This radioactive substance affects our bodies in many contrasting ways. Examples are, our organs, DNA, our tissue, bones, and TP53 gene. In this paper, we will focus most on how Uranium affects TP53 to affect our body. The official…

Uranium is the element that I chose to write about. Uranium is a element that is a naturally radioactive element that comes in a silverish metal when it’s pure. Uranium quickly oxidizes in air and it can be used to color glass that glows greenish - yellow under a blacklight. Uranium is one of the key ingredients in atomic bombs. Only 1.38% of the uranium in the bomb “Little Boy” detonated over Hiroshima underwent fission and there was 140 pounds of Uranium in total. Uranium is an element that…

Uranium Do you know how nuclear power is made? It all starts with an element on the periodic table called uranium that stands at number ninety-two. It gives off power in a single way, using uranium 235 and 238. Fission is this process of removing protons and electrons from unstable nuclei, converting them to lead. This process gives of anywhere from 1 to 5 MeV (million electron volts). You can even produce more energy by splitting the unstable nuclei even further. This type of power can, with…

Canada used to be the world’s leader in the mining of uranium. They supplied the uranium to many countries, especially the United States during World War Two. The United States were creating nuclear and atomic bombs and weapons, more specifically the Manhattan Project. Canada supplied the United States military with the uranium necessary for the weapons construction. Canada refined and processed the uranium for the use of it in United States military in 1942. Uranium is a key ingredient in…

Radioactive. Dangerous. Massive. The process of splitting the atoms of uranium is just that. Uranium is used in nuclear bombs and in nuclear energy. We know that nuclear bombs are the most deadly weapon on the face of the earth, but there is a positive way to use the uranium. We use uranium in our nuclear energy reactors to provide a clean energy for our power grids. “America’s 99 nuclear power plants generate almost 20 percent of the nation’s electricity while emitting no carbon dioxide or…

come. While thorium has a complicated history, the element remains very important to humanity for many reasons. Discovered about the same time as uranium in the 19th century, thorium has been well known to the scientific community for many years (World Nuclear Association). In fact, famous scientists like Marie Curie and Ernest Rutherford worked with the element in several experiments when nuclear decay was first being discovered. Since that time, however, thorium has largely been thrown by…

•What level of responsibility does Australia have to ensure that uranium is used for morally correct purposes? Australia has a high level of responsibility to ensure that uranium is used for morally correct purposes. For example, Australia has been shutting down some mine temporarily because of the effects of nuclear radiation to the environment and the people of Australia. •Economically, Australia gets benefits by selling Uranium. Do we have the right to tell other countries what they can and…

Nuclear power is created through the process of nuclear fission, this involves splitting a large nucleus into two smaller nuclei with the release of kinetic energy and gamma radiation. The atoms that are usually used in the process of nuclear power are uranium 235 or plutonium 239. When a neutron with energy hits uranium 235, it becomes unstable and splits into two smaller nuclei such as barium and krypton whilst also releasing kinetic energy in the form of heat and also two or three neutrons…

In the last 60 years, Uranium mining has become the basis of one of the worlds most popular sources of energy. While Uranium is almost always used for nuclear energy, it is also used in medical isotopes. To obtain Uranium for nuclear power, it is generally mined in large open pit and underground mines. Like most other mines, mining Uranium destroys the ecosystem and landscape, produces lots of noise pollution, demolishes habitats and are very dangerous. More specifically, Uranium mines have an…
