Because of all of the energy that gamma waves have, they have many interesting and useful applications.
One way that these gamma waves can be used is to treat cancer. The energy from the waves can be used to kill cancer cells on or deep inside the body depending on how much energy they possess. Surveys of gamma radiation are used to locate uranium and thorium deposits found inside the earth, and they can also be used for geologic mapping and mineral exploration deep inside the Earth's crust. Gamma waves provide many applications that are considered more advanced than other wave types because of their extraordinary amount of energy.
One of the most interesting

With a wave that possesses so much energy comes various health issues. The energy from gamma waves is

capable of killing human cells, which is positive in the treatment of cancer, but negative in all other aspects. It is very important that infants are not exposed to gamma waves, as it can mutate the developing tissues that are found in a infants body. Gamma rays also are capable of damaging
cells in all humans, and that damage can lead to cancer as the damaged cells reproduce. If the ozone layer were to disappear, humans would be unprotected from these waves and it is predicted that all life on Earth would go extinct. The picture on the left depicts what would happen if a gamma ray burst were to hit an unprotected Earth.
Gamma waves are used extensively in the treatment of cancer and in other fields of geography, and without these minuscule waves formed by super nova explosions and radioactive decay, the technology used to accomplish tasks in the fields of science and geographic mapping wouldn't be as it is today. If only we could find a way to harness the energy found in a gamma wave burst, our energy issues would be solved for billions of years.
