Uses of radiation in industry and solving crimes

  1. 1. Uses of Radiation in Industry and Solving Crimes<br />Radiation is a process where energy is emitted from the moving of electron out of its orbit. Radiation takes part in many kinds of activities, such as medical, science, industry and others. Radiation can also be used in solving crimes around many places. In addition, radiations are also useful in such areas as agriculture, archaeology, space exploration, law enforcement, geology and many others. In this essay, I am going to discuss the uses of radiation to solve crimes and in industrial activities.<br />You might wonder how radiations are used to solve crimes. Detectives and other special agents usually search for the traces of paint, glass, hair, gunpowder or blood after in a crime scene. These traces are being collected for the detectives or scientists to investigate more to find out its exact makeup. To investigate these evidences, radiation is exposed to a certain thing and then being analyzed.<br />If materials are exposed to a collection of neutrons, some of the neutrons are absorbed to the nucleus of the exposed materials. This makes the material become radioactive because they are unstable and decay with the time. Once the material becomes radioactive, scientists are able to see the chemical signatures of these substances. One of the applications is useful to determine whether a single hair found at the crime scene belongs to a certain person. Radiation can also be used to prove whether a piece of artifact or works of art are not made of modern materials.<br />The work of radiation is also used in DNA tests. There are many different techniques in DNA profiling. The goal of every technique is to identify a unique DNA profile. There is one method that uses a restriction enzyme to cut DNA strands into fragments. Then the DNA is blotted with a sheet of nitrocellulose. This sheet is later being exposed to radiation so that scientists will be able to see the DNA profile in it.<br />There are a lot of uses of radiation in industry, but we are going to talk only a few of them. With the different types of industry, there are also different uses of radiation. In an agricultural industry, radiations are used to improve food production. For example, plant seeds are being exposed to radiation so that it will be able to produce a better quality of plant. Beside that, radiation is also used in controlling insect population, which decreased the use of pesticides. <br />Engineers used radiation to determine the thickness of materials and a process called radiography to detect any defect in a metal materials and machines. Radioactive has been used to clean up toxic pollutants. Sulphur dioxides and nitrogen oxides, for example can be removed by electron beam radiation. Otherwise it will damage the environment. Radioactivity also happens in spacecraft. It is used to power the spacecraft and supply the electricity to the satellites that are sent on missions.<br />All around us, we can see that radiation plays an important role for the daily life. <br />Bibliography<br /><ul><li>Flint, Deyanda.
