Nuclear Power And Its Uses :: essays research papers

Nuclear Power and Its Uses At first nuclear power was only seen as a means of destruction but after World War II a major effort was made to apply nuclear energy to peacetime uses. Nuclear power if made when a nucleus of an atom is split to release a powerful burst of energy. Though technological advancements nuclear power now supplies us with new medical aids, a new power source and new ways to do scientific research. New medical advancements are being produced rapidly due to nuclear power. Nuclear material is now being used to treat diseases. Pacients suffering from cancer can then be exposed to the healing effects of the radiation under controlled conditions. The radiation of the nuclear energy can help in medical tests. Radioactive phosphorus is an important diagnostic aid. It is injected into the veins of a patient, it concentrates in the cells of certain brain tumors. Thyroid gland strongly attracts iodine. Radioactive iodine is used both in diagnosing and in treating diseases of the thyroid. Nuclear power is changing the face of medicine with new cures and tests that will cure millions.. Nuclear power can be converted into strong and efficient nuclear energy and be used for many purposes. Nuclear power reactors generates heat that is converted into steam. The steam can be used directly for energy. This energy is used in transportation. Most military subs are now ran by nuclear energy. The most used purpose of nuclear energy can also be used to generate electric power for example in a commercial nuclear power plant. Another way to produce nuclear energy is by gas-cooled reactors with either carbon dioxide or helium as the coolant instead of water. This method is used mainly in commercial nuclear plants in the United Kingdom and France due to the lack of freshwater. With growing popularity nuclear energy will definitely of the future with new ways to use this energy in a positive manner. Scientists can now use nuclear power for biological research to help understand life more. Radioactive isotopes have been described as the most useful research tool since the invention of the microscope. Physiologists use them to learn where and at what speed physical and chemical processes occur in the human body. Isotopes are also used for agricultural Biologists use radioactive isotopes to see how plants absorb chemicals as they grow. With radioactive cobalt, botanists can produce new types of plants. Structural variations that normally take years of selective breeding to develop can be made to occur in a few months. Many believe that nuclear power is too destructive and as such should be
