The discovery of gamma rays is generally credited to French physicist Henri Becquerel in 1896. A high frequency form of electromagnetic radiation, gamma radiation is known to cause types of cancer and other medical issues in human beings.
MEDICAL APPLICATIONS. Radiation Therapy; Radiation therapy is the treatment using penetrating x-rays, gamma-rays, or particles such as protons or neutrons on the affected region of the body to destroy the cancer cells. To produce the high energy radiation, particle accelerators such as Cobalt-60 radiation therapy unit or clinac 2100 accelerator ...
Usage of gamma rays in medical treatment. Gamma rays are ionizing radiation which can kill living cells. They are used to treat malignant tumours in radiotherapy. For treatment deep within the body, high energy photons are sent to reach the target tumour without affecting the surrounding tissue.
Gamma rays are also used for sterilization of medical equipment. Gamma rays easily pass through the packaging of medical equipment (can only be stopped by thick lead) and kill living tissue such as viruses and bacteria. Production of Gamma Rays. Gamma rays can be produced by several processes that are both nuclear and non-nuclear.
The main one that comes to mind is Cobalt 60 radiotherapy. In this therapy, a machine called an irradiator is used to direct a powerful source of Gamma rays at a tumour from multiple angles hopefully destroying the tumour. These machines are relat...
Medical applications of gamma rays include the valuable imaging technique of positron emission tomography (PET) and effective radiation therapies to treat cancerous tumours. In a PET scan, a short-lived positron-emitting radioactive pharmaceutical, chosen because of its participation in a particular physiological process (e.g., brain function), is injected into the body.
The benefits of gamma rays are most clearly seen in the medical field, where they are used to treat cancers and tumors. A technology called the gamma ray knife uses concentrated gamma ray beams to target and destroy cancer cells.
The first gamma ray source to be discovered was the radioactive decay process called gamma decay. In this type of decay, an excited nucleus emits a gamma ray almost immediately upon formation. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900, while studying radiation emitted from radium.
The gamma sterilization process uses Cobalt 60 radiation to kill microorganisms on a variety of different products. Processing with gamma irradiation yields quick turnaround time, easily penetrating packaging and product, and is ideal for many types of materials.
When atoms decay, they emit three types of radiation, alpha, beta and gamma. The alpha and beta radiation consist of actual matter that shoots off the atom, while gamma rays are electromagnetic waves. All three kinds of radiation are potentially hazardous to living tissue, but some more than others ...
