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%.
已制造出一种后装阴道施源器，它包含两个卵形源和两个呈T形排列的串联源，串联源构成竖直线，卵形源与串联源正交，位于横杆两端。施源器主体的设计和构造符合当卵形源加载10毫克镭当量137铯、串联源加载15毫克镭当量137铯时90厘戈瑞/小时的剂量分布轮廓。在前后平面和侧平面中施源器周围各点进行的热释光剂量计测量结果表明，与计算机计算的剂量相符，误差在±1%以内。
