This does not enhance their capacity to split, but it does have an important bearing on their capacity to facilitate an explosion. When a U-235 atom splits, it gives off energy in the form of heat and Gamma radiation, which is the most powerful form of radioactivity and the most lethal. When this reaction occurs, the split atom will also give off two or three of its "spare" neutrons, which are not needed to make either of the parts after splitting. These spare neutrons fly out with sufficient force to split other atoms they come in contact with. In theory, it is necessary to split only one
Peter Schwartz and Spencer Reise state nuclear power to be the best option to pollution and the earth’s ozone decay. In their article called Nuclear Power Is the Best Way to Address Global Warming, they give facts and statements such as “coal-fired plant releases 100 times more radioactive material than an equivalent nuclear reactor.”(Schwartz & Reise, 2009) These facts are undeniable and scary to anyone that hears. The thought of building more nuclear power plants to meet power demand and combat the pollution is irresponsible, due to time issues. The nation’s power and pollution issues are spiraling out of control. Understandably, there is a need for nuclear power plants and the benefits they possess, but more power plants are not the answer needed to solve today’s environmental threats.
By having helium-3 as the next power production on earth it will also decrease the amount of pollution and radioactive waste in the atmosphere. Nuclear power which involves the process of fission has provided
Natural gas is an energy source that is clean, safe and extremely useful. Natural gas is colorless, odorless, and shapeless when it is in its pure form (Naturalgas.org). This gas however gives off a great deal of energy when it is burned. Natural gas can directly play a part in reducing greenhouse emissions, strengthening energy security and helping the growing economy (aga.org). The United States consumes roughly 600 billion cubic meters of natural gas every year while we only produce about 500 billion cubic meters.
Electronic Cigarettes, I think they will work for me COMM215 Electronic Cigarettes, I think they will work for me. While not enough is known about their long-term risks or the effects of secondhand exposure, studies have shown that many people have completely quit by using electronic cigarettes by slowly lowering nicotine levels for example “Electronic Cigarettes: Do They Have a Role in Smoking Cessation?” (J.E. Odum, K. A. O’Dell, J. S, Schepers, 2012). Electronic cigarettes are more cost effective than regular cigarettes and Electronic cigarettes are safer than combustion cigarettes because electronic cigarettes do not have all of the carcinogenic chemicals that a regular cigarette has.
The supply of solar energy demeans the supply of fossil fuels when compared. The unlimited supply does not pose the same destructive effects to the environment and health. Solar energy, according to Klare (2010) “is clean, green, safe and smart” (p. 12). Solar energy provides efficiencies because it does not need the current volume of resources needed today to generate power. The predominant draw back to relying on solar power it that it will take a dedicated plan over 40 years to complete.
The use of chemicals in the hydrofracking process and the energy needed to operate the trucks and drills, critics say, offset the low carbon emissions from the burning of natural gas, making it no better than oil or coal. Furthermore, opponents contend, pollutants left behind at hydrofracking drilling sites could seep out from closed pipes and wells, posing a danger to public health for generations. Therefore, critics say, the federal government must step in to institute stricter regulations than the states have already
ed Identify a named radioisotope in medicine Cobalt – 60 Describe the way in which the above names radioisotope is used and explain its uses in terms of its properties. Cobalt – 60 is a synthetic radioactive isotope of Cobalt which is produced artificially by bombarding pure Cobalt with neutrons (also known as neutron activation), upon becoming radioactive cobalt begins to undergo Beta decay to the stable isotope Ni - 60, consisting of half life’s of approximately 5.27 years. 59Co + 1n 60Co 60Ni + e- Cobalt 60 releases two gamma ray emission lines, which are low energy and can be easily sheilded from this allows it to be used as a medical and industrial radiation source. Medical use consists primarily of cancer radiotherapy. Industrial uses include testing of welds and castings, and a large variety of measurement and test instruments including levelling devices and thickness gauges.
Australia has recently signed to Kyoto Protocol which aims to reduce greenhouse gas emission by 4 million tonnes becoming 2010. Companies have improved scrubbers, which clean sulfur from the smoke before it leaves the smokestack. Awareness is growing when considering pollution from coal. Here in Australia while we are monitoring carefully the atmospheric pollution caused by coal burning it can be stated categorically that Carbon dioxide emissions from vehicles have far more reaching effects than the pollution created from coal. Coal will continue to be used extensively in Australia because of it's abundance.
Although fossil fuels get the job done, they are finite and also pose a great threat to the earth and the stability of the human race and economy, worldwide. They can be the catalyst of war and they pollute the earth significantly. The transition to green energy needs to be made quickly, and solar energy is a key player in the game. The Problem Fossil fuels, coal, oil and natural gas, are non-renewable substances combusted to produce energy. These substances have been formed over millions of years from pre-historic plant and animal matter which lies deep in the earth and has been under substantial amounts of pressure and heat for an indefinite amount of time.
