Dynamite was invented by Alfred Nobel in order to develop the industry of getting minerals and digging tunnels; however, Dynamite is now widely used in military purpose. Similarly, nuclear energy is undoubtedly a powerful source of energy compared to other conventional fuels such as coal, oil and gas. However, nuclear energy also has a lot of disadvantages, such as nuclear wastes, nuclear plant accidents and nuclear weapons. So before widely use this technology, both pros and cons should be taken in consideration. On one hand, nuclear energy is not renewable, so the problem of nuclear waste is still unsolved. Nuclear waste is a waste produced by radioactive fissions. Unlike normal refuse, nuclear waste can be very harmful to all creatures. Radioactivity reduces over long periods of time, so the waste must be isolated until its radioactive isotopes to decay. For instance, a period of 10 to 50 years will make low-level wastes no longer dangerous. Moreover, wastes from the core of nuclear power plants and nuclear weapons emit large amounts of radiation and it take thousands of years for them to decay, some even longer than 100,000 years. Nowadays, the main approaches to manage radioactive waste is to permanently isolate the nuclear waste from the human environment such as deep burial and space disposal. But none of these methods is permanent solution.(Warren S. Melfort) In addition, a study from a Germany university, the University of Mainz, shows that kids living within a 5-kilometer radius of nuclear power stations have a 60 percent higher risk of cancer, and radiation experts also believe that children living within 50 kilometers of nuclear power stations have an increasing risk of cancer. (Spix C, Schmiedel S, Kaatsch P, Schulze-Rath R, Blettner M) On another hand, using nuclear energy is high risky. Though it is generally safe to run a nuclear plant, accidents can always happen. The Chernobyl disaster would be a good example. It was a nuclear accident occurred...
