Phantom measurements of absorbed doses in dental radiography

Some phantom measurements of absorbed doses from Norwegian dental radiography are presented. The mean bone-marrow dose from a single molar bite-wing projection was assessed to 1 mrad, a conventional full mouth examination (10 exposures) 7 mrad and an orthopantomographic exposure 2 mrad. The population dose from Norwegian dental radiography was estimated to be: mean bone-marrow dose 1 mrad and genetically significant dose 0.012 mrad.
