Nuclear energy is also harnessed to preserve our food. Pest populations are then drastically reduced and, in some cases, eliminated. In this procedure, male insect pests are rendered infertile. Agricultureįinally, farmers can use radioisotopes to control insects that destroy crops as an alternative to chemical pesticides. They can be used to identify trace chemicals in materials such as paint, glass, tape, gunpowder, lead, and poisons. Criminal InvestigationĬriminal investigators frequently rely on radioisotopes to obtain physical evidence linking a suspect to a specific crime. Nuclear medical imaging, which combines the safe administration of radioisotopes with camera imaging, helps physicians locate tumors, size anomalies, or other problems.ĭoctors also use radioisotopes therapeutically to kill cancerous tissue, reduce the size of tumors, and alleviate pain. hospitals are diagnosed or treated using radiation or radioactive materials. Medical Diagnosis and TreatmentĪpproximately one-third of all patients admitted to U.S. RPSs are proven to be safe, reliable, and maintenance-free for decades of space exploration, including missions to study Jupiter, Saturn, Mars, and Pluto. These small nuclear power sources are used to power spaceships in the extreme environments of deep space. The Cassini-Huygens probe explored Saturn with the use of a Radioactive Isotope Thermoelectric Generator (RTG) before being destroyed in 2017.Ī great deal of what we know about deep space has been made possible by radioisotope power systems (RPSs). Nuclear energy can be used in generators for exploring deep space. In fact, an international treaty was created in 2017 by several major nations to prevent nuclear weapons from spreading. The magnitude of the devastation that these weapons could create in war makes them highly regulated. The explosion also creates toxic levels of radiation for those who survive the initial blast. Using both nuclear fission and fusion, these bombs create a powerful explosion, which can demolish large areas in seconds. Nuclear WeaponsĪnother thing that comes to mind when you think about nuclear energy is weapons, like the atomic or hydrogen bomb. While nuclear power is generally reliable and less costly, the byproducts and water pollutants that it creates make it extremely controversial. These accidents affected the lives of several thousand people and caused numerous deaths. In both of these incidents, the nuclear reactors melted down, causing radiation and nuclear waste to be released into the atmosphere. You can’t talk about nuclear power plants without a discussion of Chernobyl in 1986 and Fukushima Daiichi in 2011. The spinning of the turbines produces electricity much like the turbines on windmills. The energy created heats water to spin turbines. This is done in a nuclear power plant when uranium is split within a reactor. When you think of nuclear power, you’re thinking of how nuclear fission heat is used to generate electricity. These include not only in the creation of power and weapons but also in medicine, space exploration, and more.Įxplore these examples of nuclear energy uses. Nuclear energy and its byproducts, like cobalt-60, have several uses. Inside the reactor, the nucleus of the atom is forced apart, creating nuclear energy. The fission reaction you might be the most familiar with is when uranium is used in nuclear power plants. If nuclear fusion is when atoms fuse together, then you can probably guess that fission energy is created when the nucleus of an atom breaks apart. Inside the sun, hydrogen nuclei fuse together to form helium, creating heat energy that warms the Earth. The sun is one of the best examples of nuclear fusion. In nuclear fusion, atoms are fused or combined together to create energy. When you think about nuclear fusion, think about things fusing together. Before you can look at how nuclear energy is used in your life, you need to look at the two types of nuclear energy. Nuclear energy is itself created during the reaction. Nuclear power is created by harnessing the energy from the reaction. While most of the focus is on the nuclear power created in these reactions, nuclear power, and nuclear energy are different. When an atom splits or fuses together, it creates a reaction in the form of heat energy. In other words, we get the most useable energy from smaller amounts of nuclear energy sources. Nuclear energy is our most concentrated form of energy. A chemical reaction cannot release nuclear energy. The only way for this energy to be released is through the splitting of or joining of atomic nuclei. Nuclear energy is energy that is stored within the nucleus of atoms.
