Radiation Essay

Cellular and Molecular Response to Ionizing Radiation The efficacy of diagnostic imaging resembles a double-edged sword in the medical industry. A radiographer trained to image a patient correctly must use all knowledge to keep the radiation level at its lowest and safest level to produce the best quality image possible; however, the radiation level still has an effect on the patient that can go unseen by the naked eye. Ionizing radiation produced by x-ray, gamma rays, alpha & beta rays, can have

There has been much success in the growing field of radiation therapy. Many measures have been put into place to ensure the safety of those exposed to radiation and that the treatment itself is administered properly. Although these measures are in place there isn’t too much doctors are able to do to prevent side effects. The University of Maryland Medical Center lists hair loss, nausea, vomiting, diarrhea, low white blood cells, mouth ulcers, and red or itchy skin as some of the possible short-term

Natural radiation is the radiation provided from natural occurring substances such as the sun's UV rays and the earth's crust. Natural radiation includes elements such as Uranium and Radium. Artificial radiation is synthesised (man-made) in ways such as bombarding a stable nucleus of an element with energy to create radioisotopes. This man-made radiation includes substances such as nuclear power. Electromagnetic radiation which includes waves such as radio waves, microwaves and visible light. Theses

Biological Effects of Radiation Radiosensitivity DNA as main cellular target – Cellular role of DNA – DNA is a double helix molecule made up of two sugar phosphate backbones that are linked together at the bases: Adenine-Thymine and Guanine-Cytosine. DNA is responsible for cellular structure and function. Direct vs. indirect DNA damage – ** Direct damage - Direct ionization has charged particles such as alpha, protons, and electrons. Direct damage to the nucleus of the atom is the direct damage

Along with or in place of chemotherapy, patients may need to receive radiation treatments to successfully rid themselves of cancer. The National Cancer Institute explains that radiation therapy, also called radiotherapy, “uses high-energy radiation to shrink tumors and kill cancer cells.” The Institute also describes the different forms of radiation used, including gamma rays, x-rays, or other beams of charged particles (“Radiation”). Like chemotherapy, the goal of radiotherapy is to damage the DNA

addition to being able to interact with patients. My research on Radiation Therapy instantly established a thought that this is a career

Introduction I alongside with other radiation therapy students were privileged to hear Carlas’ story from a patient point of view. Her journey through being treated for breast cancer. I could feel a strong sense of conviction in her words. She stayed strong and did not waver when speaking. I was shocked yet amazed at her confidence to tell it so clearly. It was my first time receiving insight from a radiation therapist. This paper will explore the feelings I experienced during and after this time

Radiation: a Positive Cancer Treatment People say you can’t fight fire with fire, however, radiation can do just that. Although radiation is known to cause many types of cancer, it is also one of the most effective cures. Radiation as a treatment has been used for years, but in recent years, modern technology allows radiation to become more effective and precise. Radiation is a positive treatment for cancer because it kills cancer cells, it is non-invasive, and it prevents cancer from coming back

Although commonly called x-rays, or simply radiation, scientists have more specifically termed the form of radiation, “ionizing radiation.” The World Health Organization defines ionizing radiation as “radiation with enough energy, so that during an interaction with an atom, it can remove tightly bound electrons from the orbit of an atom, causing the atom to become charged or ionized” (2014). Because the human body is made up of atoms, ionizing radiation has the ability to alter the composition of

Radiation Therapy Diana Salazar RAD: 211 Mrs. Evelyn Grove Fayetteville Technical Community College Radiation Therapy Radiation therapy is the use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors (National Cancer Institute, 2016). One of the main purposes of radiation is to preserve the normal cells while killing the cancer cells. To fully understand the importance of radiation therapy it is imperative to understand
