Depleted uranium

In conducting this experiment, the hope was to identify if there was a relationship between distance from a radioactive source and its radioactivity. Within this radiation lab experiment, we put the following hypothesis to the test: If the distance from the source, in centimeters, is increased then the Ionizing Radiation does is expected to decrease because the radiation decreases as it gets farther away from the radiation emitter, due to the loss of energy from the radioactive particles as…

There are also 66,000 tons of steel needed the same amount used in the erection of the empire state building and 44 miles of piping needed these items create jobs in many different areas of manufacturing. Other jobs are also created in the mining of uranium that is found in many places around the world. According again to the Nuclear Energy Institute the security of these nuclear facility single handedly produces 9000 jobs a year across the…

Background and Information leading to the incident The meltdown at Three Mile Island is a combination of both mechanical failure and human error. Mechanical failure was first observed at the non–nuclear part of the plant where failure in the main feed water pumps prevented the supply of water to the steam generators further cutting the heat in the core reactor. Increasing heat in the turbine generator lead to turbine shut down causing increased pressure in the nuclear portion of the plant. With…

Rosalind Elsie Franklin was a chemist and she was born in London England on July 25th, 1920. At just the age of 15 Rosalind Elsie Franklin decided she wanted to be a scientist. Receiving her education at several schools which also includes North London Collegiate School which she excelled in science. She was best known for the role she played in the the discovery of the structure of DNA, also her pioneering the use of X-ray diffraction. Franklin enrolled at Newnham College, Cambridge, in 1938…

atom has emitted an alpha, or beta radiation it nucleus would change and become an nucleus of an different element. This would be because the number of protons in the nucleus would determine which element belongs to which one. An example would be Uranium-230 nuclei emit…

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 creating a nuclear bomb and/or reactor. Split uranium…

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 the wayside for use in practical applications such…

Argon- Potassium (Ar-K) SYSTEM K- 40 is a radioactive and decays to two different daughter products, calcium-40 and argon-40, by two different decay methods (Wiens, 2002). This is not a problem because the production ratio of these two daughter products is precisely known, and is always constant: 11.2% becomes argon-40 and 88.8% becomes calcium-40 (Wiens, 2002). It is possible to date some rocks by the potassium-calcium method, but this is not often done because it is hard to determine how much…

absolutely believe that we must not use uranium as an energy source. Many people believe that uranium is a clean and a good source of energy. It is most certainly not. It is dangerous and if there is a radioactive spill, many people can be fatally injured or even killed. Uranium is not an easy source to mine and it is extremely harmful to the air while transporting it to and from. Radioactive waste disposal is an undoubtedly big issue with having uranium as an energy source. A nuclear power…

The reality of an event or issue presented by journalists to audiences is subjective, with the information contained in news packaged to present a certain representation or emphasis using the technique of framing. This conceptual narrative tool is used to “convey, interpret and evaluate information”, with frames being chosen from a range of socially available options that may be promoted by specific political or social actors or have developed culturally. (Neuman et al, 1992, p. 60) However,…
