1.	Concerning the effects of filtration: a. It increases the intensity of the beam b. It increases the half-value layer (HVL) of the beam c. It reduces the peak photon energy d. It reduces the effective photon energy e. It increases skin exit/entry dose ratio
Answer» a. False. Intensity refers to the total energy per unit area, passing per unit time, which is reduced by filtration. b. True. Filtration results in beam hardening, resulting in a more penetrative beam, and causing an increase in HVL. c. False. Filtration causes the peak photon energy to increase, i.e. the energy level that the largest numbers of photons have. d. False. Filtration increases the minimum and effective photons, i.e. those that contribute to the image. e. True. Filtration reduces the skin dose while having little effect on the image.
