advantages and disadvantages of gamma rays in medicine

The advantages of gamma scans outweigh the slight risk of gamma radiation. The first gamma-ray telescope was carried into orbit on the Explorer XI satellite in 1961. When gamma rays pass through the human body, they ionize the tissue. Radiation cannot be switched off. While the ability of gamma rays to kill cells by breaking down DNA has been exploited as a cancer therapy, gamma radiation can kill regular cells, too. Of all types of electromagnetic radiation, gamma waves have the shortest wavelength, highest frequency and most energy. That's why cancer patients undergoing radiation therapy get sick. Doctors aim focused beams of radiation, including gamma rays, at tumours. No electrical or water supplies needed; Equipment smaller and lighter; More portable; Equipment simpler and more robust; More easily accessed; Less scatter; Equipment initially less costly; Greater penetrating power; Disadvantages of gamma rays compared with X-rays. Advantages and Disadvantages of Radiation Therapy The advantages of radiation therapy include: death of a large proportion of cancer cells within the entire tumor (there are minimal, if any, cancer cells are left behind in small tumors; thus, radiation alone may be used to cure certain small tumors) Long-term exposure to low levels of radiation is associated with increased risks for cancer. X-rays do not give any sort of medical data for organs or tissues, only an image of bones. Cause mutations in DNA and produce peroxides. Because the waves can easily pass through most material, avoiding gamma ray exposure requires a shield of lead or concrete. Gamma Rays are able to kill living cells so it's used as medicine to kill cancerous cells. Sources need replacing. X-rays, gamma rays, and other forms of ionizing radiation offer an effective way to treat certain kinds of cancer. ADVANTAGES AND DISADVANTAGES The procedures for destroying agent by using penetrating nuclear radiation such as gamma rays or X-rays have the advantage that they may not need reverse assembly of weapons. She is also a submissions reviewer and grant writer for "Spout Press," an independent magazine in Minneapolis. A cell can either perfectly repair itself and continue unharmed, it can die in the process of reproduction or it can repair itself imperfectly, causing it to reproduce abnormally or become radioactive. The high-energy radiation either directly damages the DNA of the cancer cells or creates highly reactive free radicals that in turn damage the DNA of the cancer cells, killing them. Scientists measure gamma radiation in their attempts to understand how the universe works. Optical telescopes gathers and focuses light to create a magnified image or photograph, where as non-optical telescopes sense other things on the radio spectrum such as radio waves, gamma waves and X rays. (Introduction) The radiation therapy or the radiotherapy is using ionizing radiation is part of cancer treatment to kill the malignant cells, and is using the high energy to shrink the tumors such as : x-ray, gamma ray, and charged particles this is for cancer treatment. ; Anne Minard; 2009, National Aeronautics and Space Administration; Gamma Rays, National Cancer Institute; Radiation therapy for Cancer, Environmental Protection Agency; Radiation Protection; Health Effects. Regardless of how old we are, we never stop learning. Used to sterilize pharmaceuticals and disposable medical supplies. Passing food through a beam of gamma rays given off by the element cobalt-60 can extend the shelf life of meat, poultry, vegetables and fruit by inhibiting bacteria. The high-energy radiation either directly damages the DNA of the cancer cells or creates highly reactive free radicals that in turn damage the DNA of the cancer cells, killing them. Disadvantages it may not kill all bacteria on an object a person standing in the environment where objects are being treated by irradiation could suffer cell damage and cell mutation Kelly is pursuing her Bachelor of Arts in English literature from the University of Minnesota. Charley Gallay/Getty Images Entertainment/Getty Images. 1 Uses. The Disadvantages of Gamma Rays. Because nuclear medicine procedures are able to pinpoint molecular activity within the body, they offer the potential to identify disease i… But scientists speculate that a gamma burst from as far away as 6,500 light years could still wreck havoc. This means they can easily pass through medical equipment, such as syringes. Since Gamma rays are so strong, they can travel through thicker materials allowing it to be used for many different things. Fortunately, they typically originate thousands of light years away. This method commonly kills cancerous cells, but gamma ray ionization can ... 2 Ionization Dangers. His articles and op-ed pieces have appeared in the "South Florida Sun Sentinel," "St Paul Pioneer Press," "Detroit Free Press," "Charlotte Observer," “Good Medicine,” and others. When high levels of gamma rays bombard a body, a resulting dangerous ionization of tissue can cause skin cancer. Gamma rays are high-frequency waves emitted by stars and radioactive substances. If the atoms in question happen to be part of a cell in a living organism, this can kill the cell. Radionuclides can be ingested or injected into the body. The system permits the delivery of radiation from several directions, and the beams can then be shaped, or conformed, to match the shape of the cancer. PET can detect cancer in the body at an earlier stage than CT or MRI scans. Commercial radiation sterilization has existed since the late 1950s and has grown tremendously in popularity over the last 60 years. Dislodge electrons from atoms and form ions. Scientists have harnessed gamma waves for such purposes as killing cancer cells and understanding the universe, but they can be very dangerous tools. In general, ELISAs are grouped currently into the following four main categories: direct, indirect, sandwich, and competitive ELISAs. Decreased cost. The resources consist of six sets of presentations, worksheets and teacher notes that complement the Institute of Physics 2011 schools lecture “From X-rays to Antimatter: The Science of Seeing Inside your Body”: Natural radiation is often beneficial to plant growth 3⭐⭐This is a verified and trusted source Goto Source . MRIs and CT scans can show far more bone detail than X-rays. While the ability of gamma rays to kill cells by breaking down DNA has been exploited as a cancer therapy, gamma radiation can kill regular cells, too. Gamma rays are the most powerful forms of radiation because they can penetrate skin, wood, paper and other matter. The camera accumulates counts of gamma photons, which are detected by crystals in the camera. That's why cancer patients undergoing radiation therapy get sick. Gamma radiation is teratogenic, and pregnant women exposed to gamma radiation have an increased risk for birth defects when they deliver. Nuclear medicine scans are used in diagnosis and to see how internal organs are functioning. Appraisal of the advantages and disadvantages of gamma, electron, and x-ray radiation sterilization Conference Morganstern, K H Advantages of the gamma-camera in thyroid exploration (in French) Conformal radiation therapy limits radiation exposure to nearby healthy tissue as well as the tissue in the beam's path. In the late 1960s and early 1970s, gamma-ray detectors on the Vela satellite series recorded bursts of gamma rays from deep space. ELISA Formats The four most common ELISA categories. This method commonly kills cancerous cells, but gamma ray ionization can affect healthy cells. Rapid return to full employment. Gamma Camera and SPECT. Acute exposure to gamma radiation, that is exposure to a high level of radiation in a short period of time, can cause immediate negative effects, including nausea, hair loss, skin burns and diminished organ function resulting from damage to cells and tissues. Radiation that produces light in order for photosynthesis to occur is a positive effect that radiation has on plant life 3⭐⭐This is a verified and trusted source Goto Source . Long-term exposure to low levels of radiation is associated with … Each of these techniques has advantages and disadvantages that make them useful for different conditions and different parts of the body. (Radiation, n.d.) . Based on the Word Net lexical database for the English Language. Gamma rays are extremely powerful. Radiation therapy can be helpful in treating and destroying tumors in the body, but it can also cause long-term damage to tissues. About 440 million years ago, about 70 per cent of all marine species disappeared in a massive extinction, and scientists think a gamma burst may have been responsible. Acoustic neuromas (also known as vestibular schwannomas, peripheral fibroblastomas, or cerebellopontine angle tumors) are spontaneous, solitary, non-malignant, non-hereditary, slow-growing, primary brain tumors that diminish quality of life. Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose and determine the severity of or treat a variety of diseases, including many types of cancers, heart disease, gastrointestinal, endocrine, neurological disorders and other abnormalities within the body. Iodine-123 (123 I) is a radioactive isotope of iodine used in nuclear medicine imaging, including single photon emission computed tomography (SPECT) or SPECT/CT exams.
