Ionizing radiation Essays

Any organisational function that uses ionizing radiation is subject to safety requirements to ensure the protection of people who could be exposed as a result of the function. The requirements applied in Australia originate from the Basic Safety Standards (BSS) for Protection against Ionizing Radiation and for the Safety of Radiation Sources, issued by the International Atomic Energy Agency, as Safety Series 115. The standards stipulate requirements for notification of the Regulatory Authority of

Distinction must be drawn at this point between ionizing and nonionizing radiation especially with regard to their interaction with biological systems. Ionizing radiation has the ability to damage components of cells. Nonionizing radiation, on the other hand, such as radio waves and microwaves do not have similar capabilities and can at best cause heating of tissues. This claim though has been seriously doubted after a thorough scientific scrutiny, as we shall see later. Electric fields are easily

Radiation with adequately high vitality can ionize molecules; that is to say it can thump electrons off iotas and make particles. Ionization happens when an electron is stripped (or "thumped out") from an electron shell of the iota, which leaves the particle with a net positive charge. Since living cells and, all the more critically, the DNA in those phones can be harmed by this ionization, introduction to ionizing radiation is considered to expand the danger of growth. Subsequently "ionizing radiation"

Radiation can be defined as the energy travelling through space which comes from a source and may be able to penetrate various materials. There are two types of radiation and they are the non-ionizing and ionizing radiation. Non-ionizing radiation consists of light, radio and microwaves. Whereby ionizing radiation can produce charged particles in matter, and ionizing radiation is produced by unstable atoms. The difference between unstable atoms and stable atoms is that unstable atoms have an excess

Radiation and Cancer, is there a link? Shaundra Easley Vatterott College Intro to Radiology Courtney Oetting It seems now that everything is a link to cancer. However, while some reports have been perplexed, there is one report that seems to have merit. The statistics found states there is a link between radiation and cancer. According to the findings there are three reasonings that support this argument, high levels of ionizing radiation, high beam from

Radioactivity or radiation therapy uses high energy rays or radioactive substances to damage tumor cells or halt their growth, it has been used alone or along with other treatments as an effective tool for treating cancers for over one hundred years, It is estimated that about two-thirds of all cancer patients will receive radiation therapy as a stand alone treatment or as part of a more comprehensive treatment protocol. Before Ionizing particle beams, few options for both benign or malignant diseases

Physics 132 Hasbrouck 212 Cassidy Grace Lab 6: Radioactivity Abstract In this experiment we studied the strength of radioactive elements using the properties of ionizing radiation. The sources we used in this experiment are alpha, beta, and gamma radiation. We also studies the principles of the Rutherford experiments in that the nucleus was found to be very small because the forces that hold it together and also that the protons and the neutrons reside in the nucleus. Through this we also learned

radioactive medication known as radiotracers or radiopharmaceutical (Understanding nuclear medicine, 2009). Radiotracers are given to the patient through injection, swallowing or inhalation, which makes the body radioactive for a short time. The radiation is detected by a special camera, and then the image is produced. (Cain, 2013) NM is used to treat and diagnose diseases by looking to the physiology of the body (Understanding nuclear medicine, 2009). NM includes Single Photon Emission Computed Tomography

outcomes of radioactive materials used in treatments such as early detection of cancers, heart disease and others but, it’s still questioned today if these practices are unsafe due to the amount of exposure to hazardous radiation, the general population incline to blame radiation in medicine to be a significant contributor for developing cancerous cells in the human body. The following essay will outline and clarifies the uses, benefits and risks associated with the radioisotopes

and Communicating Radiation Risk in Pediatric Nuclear Medicine The children of today are the future of the world. The health and well-being of children is one of the most important issues to many people. Nuclear medicine has become a vital tool in diagnosing and helping to treat many different diseases in the world of pediatrics. The benefits of using nuclear medicine for pediatric care are obvious. The disadvantages of using nuclear medicine surround the increased radiation exposure to the children

Before the patient is given an order to have any one of them performed the doctor will evaluate the patient and their condition. Most patients know that radiation is not good for their bodies because studies show that people who are exposed to a lot of radiation in their lifetime are more susceptible of acquiring cancer. CT scans and X-rays use radiation to obtain an image, whereas an MRI utilizes radio waves instead. With that in mind, why don’t doctors use MRIs in

essay I will be talking about X-rays.I will also talk about how pneumonia is able to be treated by X-rays. X-rays are a kind of radiation called electromagnetic waves. X-ray imaging forms images of the inside of a human body. The picture will show the part of your body in various shades of black and white. This is a result of various tissues taking in various amounts of radiation. Calcium in bones take in X-rays the most, so bones look white. Fat and other soft tissues take in less, and look grey. Air

Over the years there have been concerns about the effects of workplace radiation on the health and safety of workers. As a result in Australia, as in most developed countries, legislation and regulation has been developed to provide structure and guidelines for the control of radioactive substances, radioactive sources and radiation apparatus. These Acts include procedures to prevent or limit the hazards associated with radiation for the occupational users and the general public. The regulations place

MR is a powerful imaging machine depend on the radio wave, unlike the other modalities which depend on the ionizing radiation. However, there are different sources of risk with magnetic resonance imaging, which the health providers should aware of (Dempsey, Condon, & Hadley, 2002). One of the main risks is ferromagnetic metal objects which can be projectiles with a strong static field. As the MRI develops and the magnetic field increases from 1.5 Tesla to 3 Tesla and more, as the power to pull the

Background When Ionizing radiation comes in contact with living things on an atomic level, it can have several different effects. Sometimes it causes no damage to the cell, and if it does, cells have the ability to repair themselves. However, in other cases, the radiation can damage the DNA and affect the cells ability to reproduce correctly, and thereby cause mutations. In extreme cases, radiation call also kill the cell. (scholes) It has been found that exposure to radiation can cause a considerable

uses a powerful magnetic field, radio frequency pulses, and a computer to produce detailed images of the boy’s internal structures including bones, organs, and tissues. An MRI is a safer alternative to x-rays and CT scans because it doesn’t use ionizing radiation. MRI is often used to diagnose a variety of medical conditions. MRI scans can show if a patient has cancer in a part of their body, multiple sclerosis, and heart problems. It can also be used to guide biopsies, measure blood flow, and monitor

Effects of Linus Pauling As a result of Linus Pauling’s research and discovery of quantum mechanics, scientists have developed new cures and “small” sciences. Linus Pauling invented oxypolygelatin, this substance is known as a synthetic blood plasma to be used in emergency transfusions for bad injuries in combat times (Linus Pauling, 6). He also invented the oxygen detector, this device checked oxygen levels in submarines, airplanes, and several medical environments (Linus Pauling, 6). A theory

the newfound science. In 1896, Dodd constructed an x-ray machine at the American Hospital. Not long after, he began suffering from the unprotected radiation exposure. Although no source describes the effects Dodd suffered, Arlene Alder and Richard Carlton, in “Introduction to Radiologic Sciences and Patient Care”, state that early effects of radiation exposure: nausea, vomiting, and diarrhea.

Despite the low radiation exposure, there is still a slight chance of cancer development such as leukemia in some patients, if they are not careful. In radioactive iodine therapy, some patients are required to be hospitalized and isolated because radiation continues to emit from the patient’s body for a while after the therapy. Additionally, the patient may suffer from short-term side

necessary in their personalized cancer treatment. Further, the type of radiation is determined specifically for each patient and tumor. When a patient is given pre-operative radiation therapy, the goal is usually to shrink a tumor so that it can subsequently be removed by surgery. Intraoperative radiation therapy (IORT) is given during the surgical procedure and may fall under two distinct categories: external beam radiation therapy (utilizing photons or electrons) or brachytherapy. Which modality
