The Importance Of Nuclear Physics

Nuclear physics is the study of the relationship between the nuclei of atoms. For nuclear physics to be applied in real life situations, radioisotopes are often used. These are isotopes that have an unstable protons to neutrons ratio that causes them to spontaneously undergo radioactive decay. They do this in order to change their amount of protons and neutrons and become a stable isotope of the same or a different element. To do this, they can either go through alpha decay or beta decay and depending on which one it does, it will either emit alpha particles or beta particles which will cause it to end up with a different element or isotope. When going through alpha decay, it will become an element with two less protons than the original element,…show more content…
This is a renewable source of energy which is being used fairly widely amongst the human race. Energy is created by a process called nuclear fission. In this process, neutrons are sent towards an atom at a certain speed (having a certain energy) that causes the nucleus to try to absorb the neutrons. However, these neutrons are sent in a large amount, and with there being too many neutrons, the nucleus can’t absorb them all and spontaneously breaks into uneven halves. When this happens, more neutrons are sent off at high speeds and a large amount of energy is also created. The new neutrons hit other nuclei and they split apart as well and a chain reaction starts. Each time a nucleus splits apart, energy is being created and with such a fast chain reaction the amount of energy builds up very fast. If it gets to large, the energy could create roasting, burning, or even an explosion. So in nuclear power plants, boron rods are inserted which absorb some of the neutrons given off and slow down the process. With the human population steadily increasing and the need for energy increasing along with it, there is a large demand for a reliable and renewable energy source. As of now, 68% of energy comes from fossil fuels, 19% from hydro energy and other renewable sources, and 13.4% from nuclear power plants (11). It is estimated that the fossil fuels will not last throughout the next century (10). With the renewable sources,…show more content…
Nuclear energy is nearly renewable as so little is used and it doesn’t depend on any external events. Another positive aspect about nuclear energy is that it decreases pollution and helps protect the ozone layer (8). This is very important for the future of mankind and to keep the environment and world a safe place. Finally, when compared with coal, it is considered even more safe because the pollution created by the coal is harmful towards humans’ respiratory systems whilst nuclear energy is almost only affecting humans as a
