For a 20 cm part thickness, which of the following would accommodate a 6 cm increase in part thickness and maintain radiographic density?
A)Increase the kVp by 12 kVp.
B)Increase the mAs by 100%.
C)Increase the kVp by 20%.
D)either a or b

To maintain radiographic density with an increase in part thickness, either increasing the kVp by about 15% (which is close to the 12 kVp increase depending on the original kVp) or doubling the mAs (a 100% increase) can be effective. Both adjustments compensate for the increased thickness by either enhancing the penetrating ability of the X-rays or increasing the quantity of X-rays.
