title: An afterloading vaginal applicator.
abstract: An afterloading vaginal applicator has been built that incorporates two ovoid sources and two tandem sources arranged in the shape of a T, the tandems forming the upright and the ovoids, orthogonal to the tandems, located at the ends of the crossbar. The body of the applicator was designed and constructed to correspond to the 90 cGy/hr contour for a source loading of 10 mg Ra Eq 137Cs for the ovoids and 15 mg Ra Eq 137Cs for the tandems. TLD measurements made at various points located around the applicator in the AP and lateral planes indicate agreement with the dose calculated by computer to within +/- 1%.
