The radiation burden to patients during fluoroscopy was determined for 4 important types of screening, namely the examination of the chest, the stomach. the intestinal tract with enema, and the abdomen (examination of the appendix, pyeloscopy). The duration of the fluoroscopic examinations was determined on 167 outpatients and on 677 patients of a hospital. On the average shorter screening times were found on the outpatients. The measurement of the regional radiation burden was carried out on 143 toddlers, children of a later age and adults whereby the incident doses and exit doses were each measured with 8 measuring chambers. The average and maximum values were compared with the calculated doses (surface-dose rate times time). The average dose is of the order of 10 to 25% of the calculated doses. The dose to the skin of children amounts to approximately a third to a half that to the skin of adults. For the determination of the gonad dose the latter was measured directly at the testicles of 143 male patients (adults and boys) whereas some direct measurements were made on the bodies of recently deceased female patients. The factors were determined which govern the relationship between the regional tissue dose (surface dose) and the gonad dose. In fluoroscopy of the chest of adults the gonad doses are below 1 mr, in fluoroscopy of the stomach usually below 100 mr, with enemas they may reach a few roentgen. The proportion of young persons in these investigations. however, is insignificant. Recause of the lower kilovoltage used in the examination of children the gonads of the latter are usually exposed only to from 1/10 to 1/4 of these doses. A lead apron worn at the height of the hips affords an adequate protection of the gonads during the examination of the chest and shields the gonads from direct radiation on patients who undergo an examination of their stomach. The testicles may for all examinations best be protected by lead shields. In the hands of the well trained expert the genetic radiation burden entailed in fluoroscopy is thus considerably smaller than what is usually suspected. (auth)
