Gamma ray

Nuclear medicine uses radiation to provide the diagnostic information about the specific organ functions of each person, or it is used to treat them. X-rays, CT scans, radiotherapy; all require the activity of radioactive material. Tens of millions of nuclear medicine procedures are being performed each year, and the demand for radioisotopes is rapidly increasing. While these forms of medical technologies…

society at large. Can you imagine that the orderly process of replacing damaged cells into new cells in your body stops? This is what happens with people who get cancer and if their treatment is not done fast, it can lead to death. Gamma knife therapy uses cobalt-60’s gamma radiation to destroy cancerous growth. In this paper, I will reflect on the research on cobalt-60 and its impact in the field of cancer, its impact on society and its pros and cons. “Cobalt was discovered in 1735 by a…

In conducting this experiment, the hope was to identify if there was a relationship between distance from a radioactive source and its radioactivity. Within this radiation lab experiment, we put the following hypothesis to the test: If the distance from the source, in centimeters, is increased then the Ionizing Radiation does is expected to decrease because the radiation decreases as it gets farther away from the radiation emitter, due to the loss of energy from the radioactive particles as…

is found within the gases inside the Earth’s atmosphere, and from cosmic rays from space ("Radiation in Everyday Life"). Even the human body has radiation within the muscles, bones, and other tissues. Radiation is found all over the earth. There are two main types of radiation that make all this possible, ionizing radiation and nonionizing radiation ("Radiation Explained").…

The Effect of Gamma Rays on Man-in-the-Moon Marigolds is a play written by Paul Zindel is about a young girl who learns how to speak up against the abusive people in her life. Tille lives with her verbally abusive mother, Beatrice and crazed sister, Ruth in the messy converted shop in which they call home. In the midst of chaos, Tillie is able to keep her dream alive by focusing on her love for science. Tillie displays resilient traits by recognizing the beauty of science and putting all her…

periods, emission of radioactive particles into the atmosphere, and negative side effects from its many medical uses. Radioactive particles vary in strength, alpha particles, for example, are able to pass through sheet of paper. On the other hand, gamma rays are about to pass through solid lead (6 inches) or concrete (6 feet). By analyzing the human eye, scientists were able to develop a highly accurate system for identifying the age of a corpse. This method calls of the use of radioactive…

radiation that they must shield. These include scattered radiation from the patient, primary radiation for the x ray beam and leakage radiation from the x ray tube. All x ray tubes have some radiation leakage. On average, it is about 2-3mm of lead in the housing of the x ray tube. Traditionally lead has been used as the element of choice when shielding against x-rays and gamma rays. This is because “lead is a soft, malleable, and corrosion-resistant material” (Jaquith,…

One example of a gastric emptying study is an operation that is done by nuclear medicine physicians using radioactive chemicals that examines how fast the food leaves the stomach and goes to the small intestine. Gastric emptying studies are used for checking patients who are experiencing signs of slow and, less commonly, rapid emptying of the stomach. Some signs to watch for are low energy levels, nausea, and heartburn. During a gastric emptying study, the patient eats a meal where the food in…

form of x rays and gamma rays. It is transmitted from one place to another. Ionizing radiation is high energy waves that pass the body's tissue, that produces positive and negative charged particles. These high energy waves remove electrons from atoms and cause an interaction between the x rays and the patient. This process is referred to as ionizing radiation. The amount of energy acquired from ionizing radiation is absorbed into the patients tissues. The interaction between the x rays and the…

isotope of the artificially and it has many characteristics for nuclear medicine scan the first one it has a half-life of six hours and it decay by process called “ isomeric ” and emit low energy of gamma rays and this helps to easily exit the body and can be detected accurately also emit beta rays but without high energy radiation dose to the patient is low . It has different number of compounds created for various structures such as CNS imaging it use Tc-99 ECD , bone imaging it use Tc-99…
