[Determination of the integral doses in conventional x-ray studies and computed tomography of the skull].

Absorbed energy (integral dose) is a suitable measure of radiation exposure during radiodiagnostic examinations. The integral doses from conventional and CT examinations of the skull were determined, using an Alderson-Rando phantom. The absorbed energy of one exposure using a film-screen combination and for one plane of conventional tomogram is almost identical. Considering the total absorbed energy, lower doses are to be expected for CT than for conventional tomography. A survey view is associated with reduced radiation exposure.
