Radiation Essay

Exposure to ionizing radiation is of concern to many medical practitioners. The risks of radiation exposure are well documented within the scientific literature and include cataract formation, skin cancer, thyroid disease and leukaemia.1 Medical staff who work in the operating theatre are a sizable population potentially at risk for these complications.2 With advances in medical technology in past decades and an ongoing trend towards minimally invasive techniques, there has been a significant increase

Ionizing radiation is a type of radiation that is able to disrupt atoms and molecules on which they pass through, giving rise to ions and free radicals. It is made up of energetic subatomic particles, ions or atoms moving at high speeds, and electromagnetic waves on the high-energy end of the electromagnetic spectrum. There are five primary types of Ionizing Radiation, Alpha Particles, Beta Particles, Gamma Rays, X-Rays and Neutrons. Alpha Particles are charged particles, which are two neutrons and

Coatings with radiation detection functionality. Mritunjay Sharma Zhuo Yang Supervised by Professor Steve Yeates & Prof. Francis Livens 1. Introduction Nuclear conversion of an atomic nucleus from one form to another is known as radioactivity. These conversions are accompanied by nuclear radiations, major nuclear radiations are alpha, beta and gamma radiations these are ionisations radiations and hence are dangerous to living beings these radiations can cause

traumatised state as she had learnt that she was 6 weeks pregnant and was totally upset as she was worrying that the radiation might have damaged the foetus. An assessment report on Radiation Biology was prepared ,by considering key factors such as cellular effects of radiation ,somatic/genetic effects of radiation, variation in radio sensitivity of tissues in the human body , radiation dosages used in dentistry, dental radiography and the pregnant patient and the implementation of ALARA principles

There are three types of radiation that can bring about occupational exposure. Alpha radiation can be stopped by something as thin as a piece of paper or one’s hand (BBC, 2014). Those at risk for this exposure are those who install and maintain smoke detectors, which use Americium-241. In this mechanism, an electron current interrupts smoke particles, causing the alarm to trigger when it senses smoke (Bennett, 2017). Radium 226, which is an element that is injected into tumors to battle cancer

Radiation Exposure among Health Care Workers Introduction Radiation is actuality of life and in terms of defining; it is the emission (sending out) of energy from any source. We live in a world in which radiation is unsurprisingly present everywhere and has been since the creation of this planet. Light and heat from nuclear reaction in sun are crucial to our survival. Radioactive materials occur naturally all through the environment and our bodies contain radioactive materials for example carbon-14

improved the diagnostic radiation process, however both patient and radiographer will still receive some dose of radiation. “The effects of radiation on tissue are divided into two types: deterministic and stochastic. A deterministic effect describes ionizing radiation-induced damage that occurs once a certain threshold is exceeded and increases in severity the greater the dose.1. (pg2-3) Some of the more extreme deterministic effects that occur with exposure to high amounts of radiation in a short period

Introduction: Radiation therapy is the utilization of radiation in order to treat diseases like cancer as well as to detect other ailments that someone may have. Since the development of radiation therapy many advancements have been made both to the process of using radiation itself, which in turn increased its effectiveness for medical use, and to the study of other possible uses for radiation. The concepts behind radiation therapy are not overly complicated, but they are still revolutionary ideas

The Dosage of Ionizing Radiation Increases the Risk of Cancer On November 8, 1895, a German physics professor named Wilhelm Roentgen discovered x-rays. This advance in technology helped man explore the unknown of the human body without performing surgery. Only the microscope could compete with x-rays in the “contribution to medical vision” (Gunderman 2). After the discovery of x-rays, researchers found that there were therapeutic and also cancerous results from radiation emissions. Before this discovery

INTRODUCTION Radiation procedures used to diagnose medical conditions over the past century have grown from a scientific curiosity to a pervasive, essential part of modern health care. Radiology originated with ionizing radiation to diagnose human disease, however since discovering the physiological risks associated with ionizing radiation, such as mutation/cancer, an ongoing controversy arises as to whether ionizing radiation should be used in medical diagnosis. This investigation will analyze
