Gamma Phi Beta

questionable in Liedtke’s projections was how he said he would be integrating the women’s line from Mercury but in the projections sheet he has written off the line which will reduce the revenue for the valuation of mercury. 3. What is the equity beta of Mercury? (5 points)…

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…

To understand radiation safety, one must first be familiar with the term radiation. Simply put, radiation may be defined as energy traveling through space as waves or high speed particles. There are two types of radiation, ionizing and non-ionizing (e.g. Heat, visible light), they are differentiated by how they interact with matter. Non- ionizing radiation is essential to life, but excessive exposures can cause tissue damage. Ionizing radiation has sufficient energy to ionize atoms 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,…

What are the benefits, issues, and differences between CAT scans, X-rays, and MRIs? The discovery and research of radioactive isotopes and radiation had a major impact on the creation of more elements and the grand advances in the science and medical fields. Of these advancements some of the most prominent uses of these technological advancements is the use of CAT scans, X-rays and MRI. Which are all used to get a better look at the insides of the human body, and to further diagnose serious…

“I hope I don’t get exposed to a radiation.” I thought to myself as a Nuclear Medicine Technologist in the future. Because I would have to prepare radiopharmaceuticals, I would communicate with others, and I would have to remember a ton of things, these things would be challenging about being a Nuclear Medicine Technologist. To begin, having to prepare radiopharmaceuticals would be a huge challenge to me. Radiopharmaceuticals is a radioactive compound used for diagnostic and therapeutic purposes…

most the tumor, so the cancer cells now dies. So we need radioisotopes to cure cancer because we haven’t found anything else that can. But here the problem is the cure and the discovery of cancer can cause cancer again, we are using this (x-rays, gamma-rays, treatment) well knowing that the risk of getting cancer again later in life increases a lot, which then makes less sense. We cure someone who is going to die maybe next year. This is an ethical question. Radioisotopes can make life quality…

Introduction Our Sun produces enough energy in one second to sustain life on earth for millions of years. However, there is an energy far more powerful than our Sun that makes it pale in comparison. Gamma-ray Bursts (GRBs) are the most energetic type of light in the universe and produce more energy in one second than the sun will produce in its ten-billion year lifetime. These dramatically powerful energetic explosions often originate billions of light-years from Earth yet produce a light so…

X-radiations (X-rays) are electromagnetic radiation that is utilised in performing radiographs; radiography is an imaging technique that utilises X-rays to generate a view of the internal anatomy of an individual (National Institute of Biomedical Imaging and Bioengineering 2017). The use of dental X-rays play a fundamental part in every dental clinic in terms of assisting dental professionals in diagnosing a condition, aiding in highlighting and providing early intervention for various dental…

PET is a nuclear medicine, working imaging ability that creates a three-dimensional image of functional processes within the human body. [1] First, chemicals which emits gamma radiation are injected into the human body, then; the system detects pairs of gamma rays emitted indirectly by a tracer to show images of bones and organs. These substances are injected into the body, and are usually tagged with a radioactive atom.[1] Doctors use this device to create images of bones and organs of the…
