[Present problems in x-ray diagnostics--introductory review (author's transl)].

Introductory article for a series on problems about appropriate applications in x-ray diagnostics; the following questions are dealt with:--Did the development of clinical x-ray diagnostics keep up with the technological development?--Are the costs arising in x-ray diagnostics still tolerable compared with the benefits?--Is it possible to reduce the somatic and genetic population exposure by means of appropriate measures or is it only possible to "simply" accept it?
