PHYSICS ESSAY

“The role of nuclear energy in the field of medicine”

Name: vincent ng

Grade: 10a

Word count: 1156

Nuclear energy is a type of energy which is released by a reaction called as nuclear reaction. There are two main types of nuclear reactions, one is called fission and the other one is fusion:

In Fission reaction it releases a nuclear energy when a single heavy nucleus seperates into two smaller ones,causing energy to be released . The most common element used to undergo nuclear fission is uranium because uranium has many favorable properties. Uranium nuclei can be easily split by applying neutrons at them. The fission reaction is used to make heat for producing steam, which is then used by a turbine to generate electricity.

 but if in a fusion reaction a two single nuclei combines together to form another nucleus which is heavier. This reaction occurs only under very hot conditions. Nuclear fusion is used to generate a lot of energy in the form of light, hear and radiation. This energy supports life on our planet and it was the only energy early mankind used.

In other diagnostic use of nuclear energy, Nuclear energy is used to evaluate tumors, arthritis, fractures and infenction of bones. Locating the area where there is an infection, identifying problems causing gallbladder inflammation and bleeding into the bowel can be treated using nuclear energy. It can also be used to investigate brain abnormalities, such as loss of memory, seizures and abnormalities in blood flow.

The effectiveness of using nuclear energy to solve diseases is very effective because for eg; if a patient having cancer undergoes surgery, before doing the surgery doctors need to locate the specific area where the cancer are located to do this X-ray tomography or (CT) scans work by using nuclear tracers to emmit gamma rays once the rays are inside the body, special cameras are able to pick up the emitted gamma rays and show to the photo of the organ or the part where the cancer is to the doctor. This helps the doctors to successfully treat the patient.

Another more advanced technology called a Positron Emission Tomography (PET)

Conclusion

From making this essay I came to know about the great use of nuclear power in the field of medicine, They can detect cancer, tumor and hemorrhage inside a person’s body and help doctors in treating them. But I also learnt that there is a limitation to this technology because some people have allergic reactions from nuclear energy and if exposed too much to a person’s body instead of treating the disease it can cause one, so we must be responsible using this strong energy.
