title: [Dosimetric control in interstitial gamma-therapy of malignant vaginal tumors].
abstract: Dosimetric studies were performed by means of a specially designed phantom schematically simulating the anatomy of the female pelvis, to investigate into the dose distribution of interstitial gamma-therapy. Measurements were done during the simulation of tumor irradiation in 4 regions of the vagina: in the anterior and posterior walls, in the lower and upper thirds. The urinary bladder posterior wall received the largest dose during irradiation of the anterior vaginal wall, whereas the anterior rectal wall during irradiation of the posterior vaginal wall. In comparing the calculated and experimental dosimetric data one can mark their coincidence within 20%. The authors also provide the results of a study of the radiation-hygienic working conditions of the staff responsible for administering interstitial radiation therapy.
