Use of Radioisotopes In Medicine
December 12
2013

Radioisotopes are used in the branch of nuclear medicine to convey information on the operation of a person’s organs, or to treat specific diseases. Most of the time, radioisotopes are used by physicians and other scientists such as chemists, to make a quick and precise diagnoses of the patient’s illness. The bones, heart, and thyroid can easily be viewed or imaged with the use of radioisotopes in medicine. Additionally, in some cases radioisotopes can be used to treat diseased organs or even tumors. This treatment is expended in most forms of cancer. Over 10,000 hospitals worldwide use radioisotopes in medicine. Approximately 90% of all procedures are for diagnoses. The most popular radioisotope for diagnoses is technetium-99, used for roughly 40 million procedures on a years scale, accounting for a total of 80% of all nuclear medicine procedures. Techetium-99 is a strong choice for diagnoses, because it emits only beta particles and not gamma rays. This causes minimal amounts particles infiltrate too far into the human body, as beta particles do not contain the persistence. However, technetium-99 does have a rather large half-life of 211,00 years. Still however, it is more or less safe, as it only emits beta particles. The isotope is capable of evaluating the medical condition of the heart, lungs, kidneys, liver, the spleen, bones, and can conduct general blood flow study. (http://www.worldnuclear.org/info/Non-Power-Nuclear-Applications/Radioisotopes/Radioisotopes-in-Medicine/) Diagnostic techniques within nuclear medicine use radioactive tracers. These tracers emit gamma rays from within the body. The tracers are generally short-lived chemical compounds, which allow specific physiological processes to be destroyed. The tracers can be given to the subject by injection, inhalation, or orally. Initially, photons are detected by the ‘gamma camera’, which has the ability to view organs from a variety of different angles. The camera

    Tc-99m is a very useful radionuclide in gamma imaging. The reason doctors’ use Tc-99m is because when using a gamma camera the Tc-99m emits gamma rays which will show up in the scans from the gamma camera. This allows the doctors to see how blood etc. flows through the heart, kidneys, lungs, liver, and spleen.…

    Approximately 85 percent of diagnostic imaging procedures in nuclear medicine use this isotope. Technetium-99m is made from the synthetic substance Molybdenum-99 which is a by-product of nuclear fission. It is because of its parent nuclide, that Technetium-99m is so suitable to modern medicine. Molybdenum-99 has a half-life of approximately 66 hours, and decays to Tc-99m, a negative beta, and an antineutrino. This is a useful life since, once this product (molybdenum-99) is created, it can be transported to any hospital in the world and would still be producing technetium-99m for the next week. The betas produced are easily absorbed, and Mo-99 generators are only minor radiation hazards, mostly due to secondary X-rays produced by the…

    Radiation is a form of energy. It comes from man-made sources such as x-ray machines, from the sun and outer space, and from some radioactive materials such as uranium in soil. Radiation travels as rays, waves or energetic particles through air, water or solid materials. Radioactive materials are composed of atoms that are unstable. As unstable atoms become stable, they release excess energy through a process called radioactive decay or radioactivity. The most common types of radiation emissions are alpha, beta and gamma rays. Alpha particles can be shielded by a sheet of paper or by human skin. Beta particles cannot be stopped by a sheet of paper. Some beta…

    Radioisotopes allow treatment and diagnosis of medical illnesses without the cost and trauma of open surgery (which carries risks like infection, accidents, and long recovery periods). The use of Tc-99m produces hot-spot images, which reveal early signs of disease and map how organs are functioning. The low energy gamma radiation it emits, the small dose in which it's injected and it a short half-life (6hours), minimises damage to tissues. The patient's total exposure to radiation is less than in an X-ray. So far, there have been no reported side effects.…

    Radiology is the process of working and viewing inside the human body without breaking the skin. By using radiant energy, which may take the form of x-rays or other types of radiation, we are able to diagnose and treat many diseases and injuries. Both diagnostic and therapeutic radiology involve the use of ionizing radiation (Beta, Alpha, Gamma, and x-rays), with the exception of the MRI, which uses a magnetic field rather than radiation.…
