Some of the greatest medical advancements in the modern age involve the use of many different types of radiation. Radiation therapy is used in treating multiple different types of cancer‚ and radiation from certain elements are put in X-ray tubes to save countless lives and prevent permanent injury wherever possible. Many organisations also use it for security‚ as well as the general use in the everyday home. These advancements and many more were based on the work of Marie Curie‚ renowned female

CHAPTER 1 INTRODUCTION 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

RADIATION DETECTION IN VEGETABLE LEAVES: A COMPARATIVE CASE STUDY IN COASTAL AND HINTERLAND REGIONS OF AKWA IBOM STATE BY Godfrey T. Akpabio‚ Ime E. Essien And Bassey E. Bassey. Department of Physics‚ University of Uyo‚ Uyo. ABSTRACT Radioactive radiation level was detected for five samples of vegetable leaves namely: Water leaf‚ Fluted Pumpkin‚ Editan Lasientera africana and Afang Gnetum africanum. These vegetable leaves were collected from Uyo (interland region) and Ibeno

Convection‚ and Radiation The three types of heat transfers are Conduction‚ Convection‚ and Radiation. Heat always moves from a warmer place to a cooler place. For example hot objects that are in a room that is cooler than the temperature of the object will eventually cool to room temperature. First is conduction‚ conduction is heat transferring through direct contact of substances. Then convection‚ which is the transfer of heat by the movement of the warmed matter. Lastly radiation is electromagnetic

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 and the electrons of the atoms within attenuating object deflect x-ray photons from their initial trajectories. * X-ray photons emerge from the object in all direction. * Leakage Radiation – radiation generated

The Cosmic Microwave Background Radiation Perhaps the most conclusive (and certainly among the most carefully examined) piece of evidence for the Big Bang is the existence of an isotropic radiation bath that permeates the entire Universe known as the "cosmic microwave background" (CMB). The word "isotropic" means the same in all directions; the degree of anisotropy of the CMB is about one part in a thousand. In 1965‚ two young radio astronomers‚ Arno Penzias and Robert Wilson‚ almost accidentally
