This process is called Compton scattering, wherein a gamma ray strikes an electron and loses energy, similar to what happens when a cue ball strikes an eight ball.
Ask a Question. Gamma rays from Fermi are shown in magenta; x-rays from the Chandra Observatory are blue and green.
This also explains why damage is done by radiotherapy to other rapidly dividing cells in the body such as the stomach lining hence nausea , hair follicles hair tends to fall out , and a growing foetus not because of mutations, but simply major damage to the baby's rapidly dividing cells. Gamma rays are used in an industrial setting to detect defects in metal castings and to find weak spots in welded structures.
Cobalt 60 produces low amounts of gamma radiation, which allows it to kill bacteria, insects, and yeast without causing a lethal dose of radiation in humans.
The metal is then observed by portable gamma cameras which show a darkening of the weak points in the structure on a photographic image. Retrieved from https: How they're made.
This is basically the same use as in medicine. An example would be using radioactive iodine to treat cancer in the thyroid gland. The composite image below of the Cas A supernova remnant shows the full spectrum in one image. Joshua Wade has been a freelance writer since 2006. What Are Radioactive Tracers?
These collisions create charged particles that can be detected by the sensor. Sciencing Video Vault. Advantages of Radioactive Tracers. Wade attended West Virginia University where he studied English and creative writing.
Uses for Hydrogen-3. You can find out more about gamma rays at www. NASA's Swift satellite recorded the gamma-ray blast caused by a black hole being born 12.
Gamma-ray bursts are the most energetic and luminous electromagnetic events since the Big Bang and can release more energy in 10 seconds than our Sun will emit in its entire 10-billion-year expected lifetime! Gamma rays are also used to sterilise medical equipment.
Brighter colors in the Cygus region indicate greater numbers of gamma rays detected by the Fermi gamma-ray space telescope.
Understanding the Outer Reaches of... Gamma rays kill microbes, and are used to sterilise food so that it will keep fresh for longer. Uses for Beta Rays. Doctors can put slightly radioactive substances into a patient's body , then scan the patient to detect the gamma rays and build up a picture of what's going on inside the patient.
Gamma rays cause cell damage and can cause a variety of cancers.
