Question

which of the following measurements are commonly used to describe the quality of the x - ray beam?
milligray (mgy)
coulombs per kilogram (c/kg)
milliampere seconds (mas)
kiloelectron volts (kev)

Explanation:

Milligray (mGy) is a unit of absorbed dose. Coulombs per kilogram (C/kg) is a unit of exposure. Milliampere - seconds (mAs) is related to the quantity of x - rays. Kiloelectron volts (keV) is a measure of the energy of x - ray photons and is used to describe the quality (penetrating power) of the x - ray beam.

Answer:

Kiloelectron volts (keV)
