Question

which of the following terms is synonymous with x - ray beam quality?
radioactivity
penetrability
velocity
intensity

Explanation:

X - ray beam quality refers to the ability of the x - ray beam to penetrate through materials. Penetrability describes this characteristic. Radioactivity is related to the spontaneous emission of radiation from unstable nuclei. Velocity of x - rays in a vacuum is a constant speed of light and not related to quality. Intensity is about the number of x - ray photons in the beam, not quality in terms of penetration.

Answer:

B. Penetrability
