Radiation exposure of ovaries during hysterosalpingography

Radiation exposure to an area approximating the location of the ovaries was measured in 29 patients undergoing hysterosalpingography. A thermoluminescent crystal technique was used for some patients; a pocket dosimeter placed into the upper vagina was used for additional patients. Radiation dosage varied from 75 to 550 millirads. The weight of the patient did not affect the amount of radiation delivered to the gonads. The duration of fluroscopic time was the major factor increasing dosage. A discussion of hysterodalpingographic technique and suggestions for decreasing gonadal irradiation during hysterosalpingography are included.
