[Gonadal dosis in intravenous urography and voiding cystourethrography of children (athor's transl)].
Measurements of gonadal doses of 92 children during intravenous urography and voiding cystourethrography are reported. The high deviation of doses in the testes is discussed. The application of a lead protector for the testes is demanded to decrease exposure by a factor 15 in the central beam and a factor 1.3-2 in scattered radiation. By choice of spot film radiography instead of large radiography the ovarian dose is reduced to a factor 7-40. The gonadal dose is clearly lower if 70 mm technique instead of large film technique is used. A correlation between area ionisation product and gonadal dose could not be found; therefore the genetic radiation dose cannot be calculated by data recorded as required by law.
