Ionizing radiation

be examined (through ultrasound, CT imaging, etc.) before treatment planning begins and before each treatment so that the geometry and positioning of the source to the intended target is precise and accurate. Each day before HDR treatment, the radiation therapist must utilize a departmental QA checklist. There are several components to this checklist. • Visual inspection of transfer tubes~ to make sure that the source will have a clear pathway and will not get stuck or move slowly to the…

Radiation Exposure and Image Quality in Chest CT Examinations The lone conundrum that has stumped radiologists to physicists; from the individuals wielding a bachelor’s degree, to the geniuses that have made education their life occupation. How can radiation exposure be reduced to its absolute minimum without compromising image quality? Radiation is dangerous to the human body, and its variable effects are collective throughout our lives. This scientific concept forces an ethical responsibility…

Alpha (α) Radiation The alpha radiations particles have 2 protons and 2 neutrons which are in a helium nucleus. As the alpha particles emit the helium nucleus the nucleus gives away the two protons and two neutrons. As a result of this the mass number will reduce by 4 and the atomic number will result in reducing by 2. This is known as alpha decay. One source of alpha radiation could be plutonium 239. The alpha particles have many characteristics. First of all the alpha radiation has a helium…

is that a nuclear bomb is designed to destroy organisms using heat and impact, while a dirty bomb is designed to kill with gamma radiation. Radiation from dirty bombs, besides burning through skin, also alters the DNA in bone marrows, which significantly weakens the body’s immune system, and turns some cells into cancer cells. Though nuclear bombs also emit some radiation, it is not intentional that that occurs. 2. Summarize the life and work of Henry Moseley. (3 marks) Throughout his life,…

Natalie Caparelli Mrs.Stanton October 5, 2015 Is Nuclear Chemistry Worth The Risk? Pros and Cons of Nuclear Chemistry in Medicine Nuclear chemistry, along with its advantages, has many cons such as extended decay 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…

After students have met the education requirements of a foundational program and have been certified in either; Radiography, Nuclear Medicine, or Radiation Therapy, only then are students able to start working towards post-primary certifications. The certification and registration is overseen by ARRT (American Registry for Radiologic Technologist). Candidates for CT certification are required to perform…

The X-ray, also called the Röntgen ray, was invented by German scientist Wilhelm Conrad Röntgen in 1985. The x-ray is undisputedly important and is used todays at airports and sporting events to check for weapons and dangerous substances and at hospitals in order to check for fractured or broken bones, internal damage, or items lodged in the digestive system. Despite the x-ray’s numerous and various uses, it’s discovery was unintentional. Wilhelm Röntgen discovered the x-ray while…

any slight risks. Introduction Open with impact: It’s all around us. You can’t feel it, you can’t see it, but it’s here nonetheless. I am talking about radiation of course. Radiation is energy that comes in many forms and is all around us, all the time. I have couple questions for the audience: How many of you know that x-rays are a form of radiation? Now, how many of you associate x-rays with cancer? (Show of hands) You are not alone. Relate to audience: I come from a family that shares…

(MRI) exploits the magnetic properties of the nucleus. MRI exploits the process known as nuclear magnetic resonance (NMR). In fact the technique used to be called simply NMR or NMR imaging, but the “nuclear” was dropped because of the connotation of radiation hazards from unstable nuclear sources, although there is no logical rationale for such fear. In NMR, a sample of material is placed in a strong magnetic field. The nuclei in the sample, each having a spin and therefore a magnetic moment,…
