A useful way to characterize the penetrating quality of an x-ray beam by its half-value layer (HVL). The HVL is the thickness of an absorber, such as aluminum, required to reduce by one half the number of x-ray photons passing through it. As the average energy of an x-ray beam increases, so does it HVL. The term quality refers to the mean
