To estimate the stray radiation exposure which will be delivered to the doctor during a coronary angiography we made phantom measurements. The dependence of the stray radiation from the projection angle as well as from the tube tension for fluoroscopy and cinematography was measured in the three space coordinates. Out of these results the exposure per examination can be estimated for each place and hight of the doctor. As an example a determination of exposure under practical condition as well as the means of radiation protection are discussed.
