PERSONNEL PROTECTION * Primary X-Ray Beam * Emerges directly from the x-ray tube collimator. * It moves without deflection (toward a wall‚ door‚ viewing window‚ etc). * Primary radiation is also known as direct radiation. * Secondary Radiation (aka Scatter radiation & Leakage Radiaiton) * Scatter Radiation – results whenever a diagnostic x-ray beam passes through matter. * Compton interactions between the x-ray photons

Background of the Study Protecting the patient from unnecessary radiation exposure include not only the Cardinal Principles of radiation protection‚ but also the behaviors of imaging personnel towards each patient. It is often asked‚ "Why do we need to discuss patient protection when it is the patient who is being imaged and therefore being exposed to radiation?" "And is not all radiation exposure made within safe limits so that patient protection is not really possible?" The answer centers on the concept

radiation We can classify radiation into ionizing and non-ionizing radiation‚ according to the effects it produces on matter. Ionizing radiation includes cosmic rays‚ X rays and the radiation from radioactive materials. Non-ionizing radiation includes ultraviolet light‚ radiant heat‚ radio waves and microwaves.In medical practice ultrasound and magnetic resonance imaging (MRI) involve non-ionizing radiation. +light n heat radiation produced by the sun *ionizing radiation is produced by some

Answer: Radiation has a profound effect on matter. Particularly in forms where it has high energy. There are basically two kinds of radiation‚ and they are electromagnetic energy and particulate radiation. Low energy electromagnetic radiation isn’t generally hazardous‚ as long as the field strengths are low. You wouldn’t want to stand in front of a radar antenna when it’s radiating‚ but we are swept by low power electromagnet energy all the time. Those so-called radio waves are everywhere. Light

Radiation Exposure Do you know much radiation you are exposed to everyday? Many people are not aware of the radiation levels around them on a daily basis. I believe that exposure to radiation should be minimal. I think protection and prevention is vital. Being aware of the health risks and what can be done to protect yourself should be a well known piece of knowledge. If followed‚ this knowledge can help reduce radiation exposure levels. Exposure to radiation is higher today than it has ever

Preparation Outline Public Speaking March 8‚ 2013 Specific Purpose: To inform my audience about radiation therapy. Central Idea: To clearly understand radiation therapy‚ you must know about the different types and side effects. Introduction During my life‚ I have seen how harsh cancer can be. It has took a toll of many people’s lives and changed families all over. I have witnessed it first hand as it has affected my family and has taken people from me who were very important. Experiencing

Concepts of Radiation Radiation * Emission of energy from an atom and the transmission of this energy through space. * Energy propagated in a material medium or space. * Energy in transit. What are the types of radiation? * Radiation is of two general types in our environment. * They are called non-ionizing and ionizing. Ionization * the energy transferred to the electrons causes them to be pulled away or removed from an atom entirely. * The result is the

INTRODUCTION Radiation‚ flow of atomic and subatomic particles and of waves‚ such as those that characterize heat rays‚ light rays‚ and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy
