question 2/50
x - ray beam quality refers to the:
average energy of the x - ray beam
intensity of the x - ray beam
velocity of photons in the x - ray beam
number of photons in the x - ray beam
report this question

Explanation:

X - ray beam quality is related to the penetrating power of the beam, which is determined by the average energy of the x - ray photons in the beam. Intensity refers to the number of photons per unit area per unit time, photon velocity is constant (speed of light in vacuum for x - ray photons), and the number of photons is related to intensity rather than quality.

Answer:

Average energy of the x - ray beam
