Abstract

In order to develop an ¹²⁵I seed for brachytherapy of prostate cancer, a carrier body consisting of Al₂O₃ and silver powder was developed. To optimize the adsorption conditions of ¹²⁵I on the rods, various experiments were performed. The adsorption capacity was more than 95% after 4 hours at a volume of 50 μl containing about 5 mCi of ¹²⁵I. Dosimetric properties were measured for the radial and longitudinal directions. Variations were below 11% in the longitudinal distribution and 5% in the radial distribution. This method is effective for the preparation of ¹²⁵I seeds to be used in brachytherapy treatment.
