PPT-Radiation: Overview

Radiation Emission thermal radiation is the emission of electromagnetic waves when matter is at an absolute temperature greater than 0 K emission is due to the oscillations and transitions of the many electrons . The US Environmental Protection Agency EPA is responsible for advising the government on radiation hazards and regulating certain sources of radioactivity in the environment This booklet provides basic facts about radiation science as well as inform By: John Joseph, Justin Hicks, and Daniel Silberstein. Overview. Scattering. : the deflection of radiation by particles in the atmosphere . Solar (shortwave) radiation. : the radiation that makes its way into the Earth’s atmosphere in the form of UV and visible waves. Instrumentation Readiness Review June 1, 2017. Elio .

Radiation is the giving off of high amounts of energy in the form of particles and/or waves.. The Electroscope. The Geiger Counter. Disposal of Radioactive Wastes. Radiation in Household Products. What are they? . exposure … contamination. Are they the same?. Radioactivity. Spontaneous emission of radiation from the nucleus of an unstable isotope. Disintegration Decay. Demonstrate Decontamination. JUSTIFICATION, OPTIMISATION, LIMITATION!. Balance risk against benefit, primary risk of dental radiography is cancer induction. Risk is age & tissue dependent. X-rays are short wavelength, high frequency EM radiation=high energy=ionisation of atoms. Radiation refers to the process that is concerned with the passage of energy between places through space. . It is the radiation generated by sun that . regulates the temperature of earth. . . CLASSIFICATION OF RADIATION: ionizing or non-ionizing types. . GUIDE Activity The rate of disintegration per unit time is measured in curies and based on the following standard: Unit Quantity 1 curie (Ci) 3.7 X 10 10 dps (disintegrations per second) 1 millicuri The cell life cycle The cell cycle G0 = Cell is resting G1 = RNA and proteins are made S = DNA is made G2 = Apparatus for mitosis is built M = Mitosis (the cell divides into 2 cells) G0 phase (restin . Radiation is the emission of energy in the form of waves or particles. Radiation that is so powerful that it can remove electrons from atoms is called ionizing.. Examples of types of ionizing radiation are x-rays from medical machines and gamma rays from radioactive substances. . •.
