[Radiation risks and gonadal exposure in radiodiagnosis (author's transl)]

Radiation risk is estimated from the values on radiation risk of the International Council on Radiation Protection and from our own measurements. According to these, 1 malignant growth induced by radiation is found in about 160,000 urograms, 300,000 contrast enemata or 500,000 contrast meals. In radiodiagnosis of the central nervous system the values for carotid angiograms is about 60,000, for vertebral angiograms about 16,000, for computer tomography about 50,000 and about 500,000 examinations of the skull in two planes. A mutation-induced deformity due to radiation occurs in about 4,300--26,000 colon contrast enemata, about 43,000 to 280,000 contrast meals and about 41,000 respectively 14,000 urograms in men and women in the reproductive years.
