Question Number: 399 Detection and Measurement In NTE (nuclear track emulsion) film, the tracks are caused by: A) alpha particles. B) beta particles. C) gamma photons. D) recoil neutrons. E) recoil protons. The correct answer is: E In this fast neutron responsive dosimeter, recoil protons from elastic scattering with hydrogen atoms in the film create short "tracks" of ionization as stable silver atoms are created. These tracks are counted either by eye or mechanically and equated...

LMRT Core Review Questions and Answers Rated A+ As a professional radiographer, the practice of ALARA requires you to restrict the XR beam to the clinical area of interest The factors that affect XR emission under the direct control of the radiographer are called_ factors prime Milliamperage-second (mAs) directly affects all of the following EXCEPT beam quality The factors that directly affect XR quantity are mA & filtration The factors that directly affect XR quality are kVp & beam filtrati...

X-rays: Typical diagnostic wavelength and photon energy range. - Answer-100ev-200 keV min. wavelength 6pm-12nm Structure and function of the x-ray tube. - Answer-A vacuum tube with an anode and a cathode. The cathode is heated and electrons are emitted, they are accelerated by a voltage difference in the tube. When the "brake" against the material of the anode, they release their high kinetic energy in the form of an x-ray. *x-ray tubes are of very low efficiency, most of the radiation i...

Pair production - B. Photoelectric effect Which bony landmark is commonly used for central ray location on an AP chest projection: A. Jugular notch B. T7 spinous process C. Vertebrae prominens D. Xiphoid process - A. Jugular notch What is the single, most important step radiographers can take to protect t...

RADT 142 unit 5 Test Questions and Answers Which scatter radiation interacts with moderate x-rays, outer shell electrons, and photon changes direction? - Answer-Compton/modified Which type of scatter radiation is responsible for the majority of scatter radiation reaching the image receptor (IR)? - Answer-compton/modified Compton/modified - Answer-photon is directed back towards the source (backscatter). - majority of scatter radiation reaching IR - occupational exposure during fluo...

Which of the following will decrease the amount of scatter radiation produced? a. increasing the x-ray field size b. decreasing the x-ray field size c. increasing the grid ratio d. decreasing the grid ratio correct answer: b. decreasing the x-ray field size Which of the following is not a type of beam restrictor? a. aperture diaphragm b. positive beam-limiting device c. cylinder d. lead shield correct answer: d. lead shield As collimation decreases, the quantity of scatter ra...

LRA 211 Final Review Study Guide (223/2024) Graded A+ The earliest atomic theory based on an arrangement similar to the solar system is attributed to Rutherford. The three fundamental particles of the atom are the neutron, electron, and proton. The atomic nucleus contains protons and neutrons. The component of the nucleus that has a positive charge and mass is the proton. The electron shell closest to the nucleus is lettered "K". Which of the following is not part of the electromagnetic ...
