title: Practical quantitation of radiation levels associated with newer CT scanner units.
abstract: Concern for higher radiation levels associated with some of the latest generation computed tomography (CT) scanners points to the need for dissemination of meaningful quantitative radiation dose data about these improved imaging units. Recent radiation protection survey data of some new CT installations are offered. Knowledgeable use of such information should afford CT users a basis for proper use of this valuable imaging modality within current radiation protection guidelines.
