By means of a Pressedwood phantom with the average dimensions of a 4- year-old child and an ionization chamber, dosimetry measurements were made for the following pediatric radiologic examinations; routine chest roentgenograms, conventional fluoroscopy, image intensiflcation, image intensiflcatton with television, cineradiography, and biplanar angiocardiography. The skin exposure for these procedures is tabulated and discussed in relation to previous data. The total skin dosage required for all of these procedures was found to be lower than the reported values of 136 and 60 r; it varied from 25 to 47 r for 5 procedures, Conventional fluoroscopy required the highest dose (21 r) in cardiac catheterization techniques. The following factors are recommended for keeping exposure of children to a minimum: (1) use of the long-scale contrast technique with adequate filtration for routine roentgenograms, (2) use of the smallest possible shutter opening and gonadal shielding, (3) elimination of fluoroscopy as a routine office procedure, (4) use of machines with an output of <5 r per min for pediatric practice, (5) inspection of fluoroscopes every 6 to 12 months to ensure that this output is not exceeded, and (6) use of image intensifiers rather than the conventional fluoroscope, the greatest source of radiation exposure in pediatric diagnosis.
