Radioactive Decay‚ Nuclear Fission and Nuclear Fusion When elements undergo radioactive decay the atoms of one element are changed into the atoms of another element when an alpha or beta particle is emitted from an unstable nucleus. When a nucleus disintegrates and emits an alpha particle it is alpha decay‚ the alpha particle emitted contains two protons and two neutrons which is equivalent to a helium nucleus being released. Alpha decay occurs because there are too many protons‚ which causes

Introduction Nuclear power plants produce more than 20 percent of the electricity used in the United States [Murray‚ 1989]. Unfortunately‚ nuclear fission‚ the process used to create this large amount energy‚ creates significant amounts of high level radioactive waste. More than 30‚000 metric tons of nuclear waste have arisen from U.S. commercial reactors as well as high level nuclear weapons waste‚ such as uranium and plutonium [Roush‚ 1995]. Because of the build-up of this waste‚ some power plants will

ground for the next 20-30 years. Fracking involves the use of radioactive materials‚ explosives‚ and hazardous chemicals. I believe that‚ as Fracking becomes more popular‚ and less scrutinized‚ the watch over it will become less strict‚ and these materials will leak into groundwater‚ or into our rivers and lakes. The process of Oil Fracking uses a water sand mix to open these fissures and hold them open‚ but in this water‚ radioactive tracers are inserted for the oil companies to trace the fissures

Although the effects from rare earth plant in Malaysia are yet to be seen‚ it doesn’t means that it wouldn’t become a real nightmare for us who are staying in and love Malaysia. Research before starting the operation of the company was just too simple‚ and many of the problems were neither solved nor mentioned‚ such as where to place and how to manage all the wastages produced as all of them contain radioactive substances‚ not just

will try to present some of beneficial applications of radioactivity. • Probably the most significant usage of radioactivity is in medicine. It is used in diagnostic scintigraphy‚ which is a study to asses organ function. Most frequently used‚ isotope of technetium-99m allows the quick removal of the radioisotope from the body and minimizes the risk of possible complications. Unlike X-ray studies‚ which better illustrates the structure of the organ‚ scintigraphy allows accurate diagnosis of its

at UC Berkley‚ states in his 2008 essay “Nuclear Waste”‚ that Americans and the rest of the world are overly concerned with radioactive debris and the possibility of nuclear contamination. Muller first brings to light the most common fears of storing nuclear waste; volcanic activity in the Yucca Mountains‚ the area where the waste is stored‚ and the possibility of radioactive particles contaminating the water supply. Muller then goes on to entertain opposing viewpoints on how the waste should be disposed

ethical red flags. I examined this dilemma using the Eight Steps to Sound Ethical Decision Making in Business and formulated the ethical decision is to disclose the presence of radioactive medical waste. There are a number of facts‚ consequences and the stakeholders that are critical to the decision process. If the radioactive waste was to be disclosed‚ the sales negotiation would most likely terminate‚ DAC will likely go bankrupt which will result in termination of all employees. The Florida Department
