Essay Example on Radioactive Isotopes & Umbrella Themes

Introduction

This paper is a review of umbrella theme or radioactive isotopes, and outline its application. A radioactive isotope is an atom that contains unstable combination of protons and neutrons as well, or have energy in their nucleus in excess (Thoennessen, 2016). On the other hand, isotopes are defined as one of two or more species of atoms having the same atomic number but different atomic mass (Lederer, 1980). The two elements within the isotope exhibit nearly identical chemical behavior where a single chemical element possess one or more isotopes. A good example of an isotope is carbon-12, carbon-14, and carbon-13, where all of them have the same atomic number but different atomic mass. There are two main types of isotopes which include natural and artificial isotopes. To begin with, natural isotopes are those that exist naturally. An example of an element that contains natural isotope includes hydrogen, which has three isotopes, namely protio, deuterium, and tritium (Thoennessen, 2016). Artificial isotopes are manufactured in laboratories where subatomic particles are bombarded but have a short life span.

The unstable nucleus of a radioactive isotope can occur artificially or naturally, where there is an alteration of an atom (Thoennessen, 2016). On some occasions, a nuclear reactor is used in the production of these radioactive isotopes. In this regard, this nuclear reactor is used to produce neutron, rich in radioactive isotopes, for instance, molybdenum-99. One of the common examples of umbrella theme as established in the study radioactive that occur naturally is uranium. Uranium-238 constitutes 0.7 percent of the naturally occurring uranium. The rest of the uranium is less stable or even more radioactive. An example is uranium-235, which comprises of three fewer neutrons in its nucleus (Thoennessen, 2016). Atoms that are unstable in their nucleus tend to regain their stability by shedding excess molecules in them and energy, which happens in the form of radiation by a process known as radioactive decay.

Application of Radioactive Isotopes

Umbrella theme or radioactive isotopes have a wide application area. In general, radioactive they are useful since their radioactivity can be detected, and also the energy released by them can be used (Young, 2009). These isotopes are effective tracers since it is easy to detect their radioactivity. A tracer, in this case, is a substance that can be applied to make a follow up of that particular substance through some structure. For example, tritium can be used to detect some leaks in underground water pipes (Young, 2009). In doing so, a Geiger counter can be used to monitor and locate any particular radioactive tritium present in the underground pipe. Additionally, a tracer can be used in the following steps that involve complex chemical reactions. Umbrella theme are also used to establish the age of various objects, for example, fossils.

In medicine, radioactive isotopes are used to treat and diagnose disease and sterilizing especially surgical environment (Young, 2009). They are also used in the field of agriculture in plague control and food conservation. Radioactive isotopes are also used in industrial radiography. In this application, a gamma source is used to carry out stress testing and also checking the integrity of welds (Winker, 2009). For instance, radioactive isotopes are used in the testing of airplane engines where they determine the engine's structural integrity.

Moreover, umbrella theme is used for gauging purposes to measure or detect the level of liquid in a container (Winker, 2009). Radioactive isotopes are also used in the detection of clandestine nuclear activities in weapon production. Finally, the application of umbrella theme is diverse especially in scientific research to trace the flow attributed by contaminants in the biological system. Therefore, it is evident from the review above that umbrella theme or radioactive isotope has a wide area of application especially in the field of industry and in scientific research.
