Gamma ray

CT scanners and X-ray machines are extremely similar in relation to the absorption and display of x-rays as they are both able to display bone. However, an x-ray is usually done when dealing with bones rather than a CT scan as x-rays can detect denser materials better. When the x-ray is being done a black photographic film is placed behind the part of the body that is being scanned and when the x-ray beams hit this part of the body, the bones block the x-ray beams meaning the blocked image is…

radiation naturally but other sorts are made in a lab for specific purposes like radiotherapy for the treatment of some sorts of cancer. Radiation as a medical treatment has been around for a long time. X-Rays as such were discovered in 1896 by Wilhelm Roentgen and as early as 1901 low dose X-Rays were being used to treat cancer. It was found early on that radiation seamed to treat diseased cells in the body and if a method could be found for confining their effect to the cancerous cells and…

The experiment investigates a GM tube and a GM counter and the relationships of radiation. The experiment uses a GM tube to detect radiation coming from a source. This is done by the decay particle ionizing and causing the charge to build up in the tube, which is discharged and the discharge is counted by the counter and added to a display. The GM tube must be calibrated at the best voltage so that the count rate is independent of the voltage. A test was done to find this value by changing the…

Nuclear Chemistry: The Magnetic Resonance Imaging The evolution of medicine is quite interesting. It first started out with spirits, omens, and other mythical beliefs. Then, the discovery of science has allowed for more practical ways to examine and heal a body. First the simple tools came into play, then the advanced technology. As the years keep progressing, more and more discoveries are being made. One example of this is magnetic resonance imaging (MRI). Nuclear chemistry has allowed for…

helping others. Within Gamma Phi Beta, Natalie is very involved. She attends all chapter meetings, and other sorority events. At each event, Natalie checks in with the vast majority of the chapter to make sure they are feeling their best. Natalie loves to build her sisters up and encourage them to be who they truly are. Natalie was one of the first people I met when I joined Gamma Phi Beta, and she proved to me that Gamma Phi Beta was the place for me. During Natalie’s time in Gamma Phi Beta,…

My name is Karen Holmes and I am the Education Assistant at Kappa Kappa Gamma Headquarters. Your District Director, [District Director name], recently contacted me to place a request for an Every Member Education Trainer visit for your chapter. This workshop should take place [time frame for workshop]. The topic to be presented…

cannot be reached. What do authors try to achieve by showing this? Does lack of freedom drive people over the edge? Readers are forced to decide for themselves through underlying questions, symbols, and themes. Both Aldous Huxley’s Brave New World and Ray Bradbury’s Fahrenheit 451 portray the effects of a society without freedom through these themes: the incompatibility of happiness and truth, the role of knowledge versus ignorance, and the use of technology to control society. The characters…

Radiography is the process of producing x-ray pictures, also known as RADIOGRAPHS. X-rays were discovered on November 8, 1895 by Wilhelm Conrad Roentgen in Germany at the University of Wurzburg. Radiographs are produced through the use of radiation. There are three different types of radiation. These include PRIMARY RADIATION, REMNANT RADIATION, and SCATTER RADIATION. Primary is the radiation that leaves the tube, remnant is the “exit radiation” that passes through the image receptor, and…

it has been widely-used ever since. The first use of nuclear energy in the medical field is for medical imaging which is a way of creating visual representation of what is going on in our body. Medical imaging began when Wilhem Rontgen discovered x-ray in 1895. However, at that time, the dangers of radiation was not known yet. Fast forward about 20 years later, contrast agents which are harmless to the body were used to visualize bile ducts, gall bladders and our digestive systems. By the 1950s,…

Sagittal, coronal, and axial planes are all optimal diagnostic viewpoints. A Computed Tomography unit utilizes an x-ray tube and a detector array to find anatomic information from a patient. A typical repeating method that is required is an intravenous infusion of an iodinated contrast agent which helps to distinguish between pathology and ordinary tissue. Since the…
