Certainly there's another way to calculate average density without cutting off a head. X-rays come to mind, or gamma-beam-blasters, or having a friend thwack it with a thumb while pressing your ear against the opposite side. I imagine that if such a technique exists, it has been performed by scientists somewhere, probably resulting in the figure I cited. The only reference which that website gives that could be its source is likely "Characteristics of the SAR distributions in a head exposed to electromagnetic fields radiated by a hand-held portable radio," which seems to indicate a beam-related method of some kind. However, I am not a physicist, just a schoolkid who wants to be one.
