Rt Simulation Examination 1

This is a Simulated Examination for Gulf RT Examinations taken from Last Month's HAAD Feedbacks. This examination contains 100 of the most UPDATED EXAMS from Abu Dhabi, KSA, and UAE. Take this examination for 120 minutes. You need to get 86% to pass the HAAD. 60% to pass MOH, DHA, or Prometrics. Please text 0919-286-29-29 in the Philippines or visit our website www. Rtonline. Weebly. Com THIS IS YOUR ASSESSMENT FOR ANY GULF RT EXAMINATIONS INCLUDING HAAD RT, SAUDI PROMETRICS, DUBAI DHA, AND UAE MOH. THE QUESTIONS HERE ARE TAKEN FROM THIS ACTUAL EXAMINATIONS, SO PASSING THIS ASSESSMENT EXAM WILL GIVE YOU A HIGH PROBABILITY OF PASSING THE SAID EXAMINATIONS

    Terra / BTX uses X-rays to produce the desired X-ray diffraction pattern or X-ray fluorescence spectrum.  These X-rays are produced from:
    • A. 

      A radioactive isotope within the instrument

    • B. 

      A gamma ray neutron source within the instrument

    • C.

    • D. 

      None of the above

  • 6. 
    Radiation which has sufficient energy to remove electrons from atoms in materials through which the radiation passes is called ionizing radiation.  Examples of ionizing radiation include all but:
    • A. 

      Alpha particle radiation

    • B. 

      Neutrons

    • C. 

      X-rays

    • D. 

      Radio waves

  • 7. 
    The damaging effects of radiation depend not only on its intensity and duration, but also the type of radiation.  For instance, 1 millicurie of tritium a centimeter from the body poses a much different hazard than 1 millicurie of phosphorus-32 a centimeter from the body. Consequently, it is often preferable to measure radiation by describing the effect of that radiation on the materials through which it passes.  The units for biological effects of radiation are:
    • A. 

      Exposure

      Absorbed Dose

    • C. 

      Dose Equivalent
