Questions and Answers

What determines the maximum X-ray energy produced in an X-ray tube?

  • Exposure time
  • Current
  • Voltage (correct)
  • Rate of electron flow
  • How does the rate of X-ray production vary with the X-ray tube current?

  • It is inversely proportional
  • It is directly proportional (correct)
  • It has no relation
  • It remains constant
  • In an X-ray tube, what happens when high energy electrons collide with the anode?

  • They create a vacuum
  • They interact with the anode material, creating typical radiation of the anode element (correct)
  • They produce X-rays of lower energy
  • They emit gamma rays
  • How does the energy of gamma rays typically compare to that of X-rays?
