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.
X-rays, gamma rays, and other forms of ionizing radiation are used to diagnose and treat some medical conditions. This can be in the form of radiation that penetrates from outside the body, or radioactive particles that are swallowed or inserted into the body. Certain types of imaging tests, such as ...
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 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. Gamma rays are also used in PET scans and bone scans to detect malignancies.
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 ...
Gamma-ray therapy. Gamma-rays are sometimes used to treat cancerous tumors in the body by damaging the DNA of the tumor cells. However, great care must be taken, because gamma-rays can also damage ...
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.
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 damage the cancerous cells' DNA, causing them to die or reproduce more slowly. Often used in conjunction with surgery or chemotherapy, radiation therapy targets tumors with a focused beam of gamma-rays. However, gamma-rays kill both healthy cells and cancerous cells.
