Radiation poisoning

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…

Spectroscopy is the study of how matter and electromagnetic radiation interact with one another. In this experiment, we are observing and recording the emission of photons with wavelengths on the visible light spectrum. To understand…

Introduction: The ability of substances within a solution to absorb light is a wonderful phenomenon as it aids in processes such as determining the concentration of proteins. The way that a solution absorbs light is due to the photoelectric effect. The way the photoelectric effect works is that when light comes in contact with the sample, the photons of light will react with its electrons. As the light travels through the solution, "a photon of light may interact with an electron ... [where]…

Astronomy Practical – Carey Zimmer The aim of this experiment is to verify the inverse square law involving the light from the globe of an optics kit (The star) and a light meter placed some distance away. This is to be done by analysing the relationship between the source and the detector. Hypothesis: If the distance between a light source and a light meter increases, then the amount of Lux recorded on the light meter will decrease. Materials: • Light box kit • Power supply • Meter ruler •…

Radiotherapy Radiation has many beneficial ways to be used. The type that will be discussed in this report is its medical uses in treating cancer. The treatment is called radiation therapy or radiotherapy (National Cancer Institute 2010). More than half of all cancer patients get radiotherapy as part of their treatment (American Cancer Society 2014). It is often used alongside chemotherapy (D Hermann n.d.). The purpose of radiation therapy is to cure or control the cancer or to relieve symptoms…

contraindication of contrast media In the radiation they are using many tints , e.g. barium also We are using in the nuclear medicine and it’s called radiopharmaceuticals such as Carbon-11 , Chromium-51 , Fluorine-18FDG , Gallium-87 , Gallium-86 citrate , Technetium-99 , Iodine-123 and Iodine-131 . there are all these different uses pigments have benefits and harm . Firstly , we will talk about Iodine-123 is used to diagnoses the patients . It use for routine scan the time of…

give off small amounts of radiation that can be read by a camera. A computer puts all of these little points of radiation together to make a picture. Radio isotope imaging is used by more than 10,000 hospitals worldwide and has become a valuable tool in the detection of many diseases.…

Slow, sleepy, Sunday mornings are the best with you. Your little toasty toes pitter across the floor while you linger closely at my heels babbling in a language only you could ever understand. With my coffee in hand we begin our day. Mundane tasks of laundry and dishes turns into your adventure of, "How much of a mess can I make?" You always seem to be right under my feet and I'm tripping. I'm tripping and falling. Falling -in love- with you. Dearest Daughter, I see myself in you. Today you…

Session on surgery, radiation therapy and chemotherapy are the conventional treatment options for cancer therapy. To maximize the killing effects to the tumor, the combination therapy with surgery and radiation, or chemotherapy are most often used (Tannock 1998). However, for treatment of small, poorly defined metastases or tumors embedded within vital regions, such as brain, conventional treatment options may not be able to provide effective therapeutic outcome (Hirsch, Stafford et al. 2003).…
