title: [Effective prefilter and patient dosage].
abstract: The dose of incidence at a distance of 1 m from the focus is stated as pre-filtration characteristics of modern x-ray tube assemblies for estimating the patient dose. The examinations cover a constant d.c. voltage range from 40 to 150 kV and the exposure range that is of practical interest.
