Contribution to the determination of genetically significant dose owing to radiodiagnostic methods in the Madrid area

The results of the determination of genetically significant dose owing to radiodiagnostic methods in the Madrid area are presented. The value obtained for this magnitude is 220+- 60 mu G y. The values for child expectancy, on the basis of age and sex, the number of each type of exploration per 1.000 habitants per year, distributed according to sex and age, and the values corresponding to the dose in gonads for each probe are also presented. The sample was obtained from 4 large hospitals in the Madrid area, 2 outpatient clinics and some private centers, affording a total of some 700 determinations of dose in gonads. (author)
