  • The Nuclear Metals Incorporation and the Mess They Left Behind

    634 Words  | 2 Pages

    The Nuclear Metals Incorporation or the Starmet Corporation is located on a 2229 Main Street in Concord, Massachusetts. The site produced depleted uranium products for armor piercing ammunition. They also created metal powders for medical applications, photocopiers, and specialty metal products, such as beryllium tubing for aerospace needs. From1958 to 1985, the holding basin that contained all the industries waste such as depleted uranium and copper was unlined, which caused issues.

  • Strontium Research Paper

    577 Words  | 2 Pages

    In 1790 a discovery was made by an Irish Chemist named Adair Crawford. This discovery was the thirty-eighth element on the periodic table, Strontium. Its name comes from the town Strontian, Scotland where it was discovered. Strontium is a metal and belongs to the alkaline earth metals. “The alkaline earth elements are metallic elements found in the second group of the periodic table. All alkaline earth elements have an oxidation number of +2, making them very reactive. Because of their reactivity, the alkaline metals are not found free in nature” (Bentor). Being in period number five, Strontium has an atomic number of thirty eight which represents the number of protons in the nucleus. There are approximately eight-seven point sixty-two protons and neutrons in the atom which gives Strontium its atomic mass. Another way that Strontium can be represented is through its symbol Sr.

  • Radioactive Waste Essay

    675 Words  | 2 Pages

    The use and management of radioactive materials is not a topic that is generally discussed in abundance to everyday citizens. Many people do not know what radioactive waste is or even the effect that it can have on the human body. Radioactive waste is a type of waste that has some type of radioactive material inside of it. The managing of this radioactive waste is extremely important because it can cause damage to living tissue. Without a place to properly dispose of or contain, the radioactive waste can contaminate our water, food, air, or even our land. If this happened it would be detrimental to all human’s health, causing many different problems throughout the world not only with the health of the population, but problems with the environment as well. Therefore it is vital that we have somewhere to put these radioactive wastes.

  • Nuclear Energy Essay

    2004 Words  | 5 Pages

    On and off, could it be that simple? Energy is there whenever we need it, so we think. It’s not as simple as turning the light switch, replacing light bulbs, and paying the electric bills. Our energy today is made mostly from coal, natural gas, oil, wind, solar, and nuclear. With depleting natural resources, we must begin to consider what will power our future. Although there are many challenges yet to be encountered and technology yet to be discovered, many say nuclear energy is becoming a major part of our future. However, nuclear meltdowns and disasters have many people and scientists questioning the possibility of having a nuclear powered world. What are the concerns and positive aspects of nuclear energy today? Could nuclear energy become a part of our future energy source?

    Nuclear energy has been a controversial source of alternative energy since it has been made practical in the 1950s. The goal of nuclear energy was to find a sustainable resource that would be able to replace the use of fossil fuels. Due to the exploitation and finite supply of resources such as oil and coal, an alternative to fossil fuels was needed quickly in order to provide sustainability for the future of the world. A question arises, however, when nuclear energy is considered as a source of energy: Is nuclear energy a reasonable alternative to fossil fuels?

    Nuclear power is the generation of electricity from an atomic reaction. (World Statistics: Nuclear Energy Around the World n.d.) Though it produces zero carbon emissions there has been a decline in support for nuclear power and increased its support for alternative energies in the pursuit for a fossil free energy sector. Factors that have resulted in the reduction of support for nuclear energy include nuclear accidents and waste and the positives of renewable energy which include clean energy, sustainable and reduced health and environmental risks.

  • Nuclear Energy Essay

    715 Words  | 2 Pages

    Nuclear energy is produced from the splitting of millions of uranium atoms in a very interesting process called fission. This type of process is used in big power plants where there are numerous tools and machinery that help produce the energy. From generators to pumps to turbines and transformers there are up to 12 main components that all come and work together to create high amounts of electricity. The fission process is used to produce a lot of heat and steam from the reactor where uranium rods are placed. That very hot steam then travels to big turbines and spins them through the generator to generate and produce high amounts of electricity. The electricity then travels to transformers and from there it travels through land wires that run hundreds of miles into cities and towns (World Nuclear Association [WNA], 2014).

    It is not uncommon to find a group of school aged children playing at a playground or neighborhood park. Now imagine that you are playing a friendly game of four-square with your classmates one minute and the next minute, everyone is gone. A massive explosion caused by a strange object falling from the sky. What could possible cause such an extreme disaster? A chemical reaction caused by the isotope of the element Uranium known as Uranium-235. The isotope Uranium-235, which only makes up a small fraction of natural uranium, changed the scope of nuclear disasters from a small scale to a global disaster (Uranium-235).

    Radioactive elements were not known of until about 1896 when a man named Henri Becquerel was experimenting with uranium to see why it was fluorescent under UV light. He believed that as the uranium sat in the sunlight, it absorbed sunlight and reemitted it on the paper, creating the film. He later found this to be incorrect when the uranium continued to create film when not exposed to sunlight. This was because the energy was not coming from the sun, but rather from inside the uranium.

  • Essay On Radioactivity

    1075 Words  | 3 Pages

    One of the greatest events of twentieth century was the use of radioisotope as a source of energy and as medical and industrial tools. Using radioactivity has been a global issue owing to its very nature. When it is used for peaceful purposes, it is a triumph of science because it can solve energy problems in the form of nuclear energy but the side effects in the form of harmful radiation and harmful radioactive waste is the real limitations of science. This essay will attempt to analyze the application of science in the use of radioactivity and radioactive isotopes and how science is not so effective in dealing with the side effects.
