Radiation therapy

Radiation is defined as emission of energy in the form of x rays and gamma rays. It is transmitted from one place to another. Ionizing radiation is high energy waves that pass the body's tissue, that produces positive and negative charged particles. These high energy waves remove electrons from atoms and cause an interaction between the x rays and the patient. This process is referred to as ionizing radiation. The amount of energy acquired from ionizing radiation is absorbed into the patients…

I. Introduction In this project we were meant to study the amount of radiation the students of Chavez High School are exposed to. The amount of radiation was accumulated through a survey that was handed out to each grade level and according to their responses we would sum up the total and give an average of how much radiation intake each student could possibly have. This research project was done so as to give us a taste of the type of research work we would have when/if we…

children with cancer. Children are more likely have to severe side effects from radiation than adults because children…

large. Can you imagine that the orderly process of replacing damaged cells into new cells in your body stops? This is what happens with people who get cancer and if their treatment is not done fast, it can lead to death. Gamma knife therapy uses cobalt-60’s gamma radiation to destroy cancerous growth. In this paper, I will reflect on the research on cobalt-60 and its impact in the field of cancer, its impact on society and its pros and cons. “Cobalt was discovered in 1735 by a Swedish…

cancer, which uses forms of radiation. It uses high-energy rays to treat disease and it works by destroying cancer cells in the area that's being treated. With external radiotherapy a carefully controlled beam of radiation targets the area where the cancer cells are found. A team of radiation therapists, cancer specialists and physicists try to work out the best way to target the cancer whilst minimising the damage to other tissue. For curing cancer the radiation needs to be very carefully…

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…

Specifically, we shall discuss whether the concept of Hormesis is existed. We shall also discuss the two types of Hormesis, inhibition and stimulation. More specifically we shall discuss the role Nuclear Medicine, Radiology and Radiation Therapy play in Hormesis as it relates to radiation. Finally, we shall discuss our thoughts on the Hormesis theory; specifically, if it a feasible concept or simply far-fetched. Hormesis is defined by the National Institute of Health (NIH) as an “Environmental…

green visible gas Nuclear Imaging works on the principle of radiation (which is invisible by the way) and how to detect radiation. A radioisotope tracer is inserted into a chemical prevalent in your body like glucose. It consists 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.…

Introduction Radiation protection policy is distributed among several governmental Agencies in the United States. Each agency is tasked with controlling exposure to radiation and the safe use of radioactive materials and radiation generating devices. These agencies inform their policy with reports and recommendations from a number of organizations, including the National Council on Radiation Protection and Measurements (NCRP). The NCRP is a longstanding organization that strives to provide…
