Technetium-99m (99m Tc) is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99m Tc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope in the world.. Technetium-99m is used as a radioactive tracer and can be detected in the body by medical equipment (gamma cameras). The alpha, beta, or gamma rays they emit during their fugitive radioactive decay signal their presence. But this type of radiation can also be man-made. Uses in Medicine Gamma rays are widely used in medicine and specifically in the area of oncology to treat malignant and cancerous tumors during a process called gamma knife surgery. But wherever radiation has been put to use, it has turned out to be a razor-sharp double-edged sword. Routine therapeutic applications of gamma rays in teletherapy and brachytherapy, but also modern techniques as gamma-knife radiosurgery, are presented. X-rays and gamma rays are created in power plants for nuclear energy, and are also used in smaller amounts for medical imaging tests, cancer treatment, food irradiation, and airport security scanners. Unlike alpha and beta particles which have both energy and mass gamma rays are just pure energy. Curie theorized that radiation could even become very dangerous in criminal hands and thus questioned whether mankind would benefit at all from knowing the secrets of Nature, particularly with concern about radiation use in war. Here are some of their most common uses: Broken bones. Gamma rays are generally used for the sterilization of gaseous, liquid, solid materials, homogeneous and heterogeneous systems and medical devices, such as syringes, needles, cannulas, etc. Tiny objects of the infinitely small, radioisotopes are innumerable even in minute proportion in the matter. Medical Uses of Radioactivity January 2003 Fact Sheet #320-072 Division of Environmental Health Office of Radiation Protection Since the discovery of radiation, people have benefited from the use of radiation in medicine,agriculture and industry. This treatment uses focused beams of radiation to treat cancer tissues without a surgical incision or opening. They are used in medicine … It uses beams of gamma rays to treat injured brain tissue by damaging the DNA of dangerous cells. The radioisotope most widely used in medicine is Tc-99, employed in some 80% of all nuclear medicine … Medical uses of radiation. Coincidence detection- simultaneous detection of the 2 gamma rays on opposite sides of the body. [2] Gamma irradiation is a physical means of decontamination, because it kills Uses of microwaves waves. However, gamma rays can also be used to treat cancer. Gamma irradiation is used in the field of medicine, which is a physical and chemical means of sterilization. It’s most often used in the brain. A radioisotope used for diagnosis must emit gamma rays of sufficient energy to escape from the body and it must have a half-life short enough for it to decay away soon after imaging is completed. An international team of astronomers has carried out multi-wavelength observations of a blazar known as TXS 1515–273; they detected very-high energy (VHE) gamma-ray … Another common use of gamma rays is in the treatment of certain types of cancer. The detection of the two 511 keV gamma rays forms the basis for imaging with PET. In the field of medicines, gamma rays are used for radiotherapy and sterilizing medical equipment. X-rays penetrate different objects more or less according to their density.In medical field, X-rays are used to generate images of tissues and structures inside the body. This procedure is called "Radiotherapy", and works because cancer cells can't repair themselves like healthy cells can when damaged by gamma rays. A brief treatment of radioactive isotopes follows. What is gamma ray light used for? Some medical imaging equipment involves the use of gamma rays, such as the Gamma Camera below: Image courtesy of Addenbrooke's Trust, Cambridge. Gamma Knife uses very precise beams of gamma rays to treat an area of disease (lesion) or growth (tumor). Gamma rays have a range of uses gamma rays are used for killing things for example in teletherapy they are used to kill cancer tissue by delivering a radiation dose to it. X-Rays are a form of electromagnetic radiation studied in GCSE physics. Are gamma rays used in chemotherapy? Gamma rays are undeniably providing significant advantages most especially to the field of medicine and technology. Gamma-ray imaging in medicine Introduce a gamma-emitting radioisotope into body (attached to a biologically interesting molecule) and observe how it distributes through different organs. These rays are now widely used in industrial and commercial purposes. Gamma rays are emitted by unstable nuclei via radioactive decay with a fixed wavelength. A gamma camera is a piece of medical equipment that is capable of detecting gamma radiation. All gamma rays emitted from a given isotope have the same energy, a characteristic that enables scientists to identify which gamma emitters are present in a sample. Gamma rays or gamma radiation is dangerous because it is ionizing radiation. That is, it is powerful enough to knock electrons from atoms to create ions. In a cell in your body, for example, those ions disrupt the cell metabolism which in turn may cause a number of things to happen. This feature is widely used in medical imaging to detect X-rays or gamma rays. Therefore, gamma radiation is used for the sterilization of medical devices. what is another use for gamma rays apart from detection and cancer treatment and sterilization? University Of Kufa. Use of Gamma Radiation Techniques in Peaceful Applications. The gamma camera records the energy emissions from the radiotracer in your body and converts it into an image. Because Gamma rays can kill living cells, they are used to kill cancer cells without having to resort to difficult surgery. X-rays can penetrate through the flesh and the bones very easily. These waves are generated by radioactive atoms and in nuclear explosions. Edited by Basim Almayahi. Getting the dose right is very important! It kills bacteria deposited on the medical equipment by breaking down bacterial DNA, inhibiting bacterial division. Uses of gamma rays in medicine? The irradiation of the surgical equipment with high energy gamma radiations cause the bacterial DNA to break down. The amount of radiation you receive depends on the examination being performed. Uses Gamma rays can kill living cells, they are used to kill cancer cells without having to resort to surgery. It has radiation detectors called gamma camera heads. They kill living cells and the rays they produce can cause cancer, however, when used in certain ways they can kill cancer cells.
