title: Radiation gonad doses received by children in intravenous urography and micturition cysto-urethrography.
abstract: Measurements of gonad doses in intravenous urography (IVU) was performed on 47 children and in micturition cysto-urethrography (MCU) on 57 children. Ionization chamber dosimeters were placed rectally in girls and fixed on the scrotum in boys. Gonad dose ranged from 27 mrad to 201 mrad in girls and from 7 mrad to 112 mrad in boys during IVU; during MCU doses ranged from 53 mrad to 1900 mrad in girls and form 24 mrad to 309 mrad in boys. Risk of leukemia and genetic risk were calculated.
