A method of iodine-125 deposition on a surface of microsource silver supports for brachytherapy of prostate cancer was reported, which includes preparing the support surface by sequentially treating them with nitric acid and thiourea solutions, followed by chlorination of the support surface with a chlorinating agent to form silver chloride on the support surface, and substitution of chlorine atoms for
125 I atoms by placing supports containin silver chloride on the surface in a solution with125 I ions to create a125 I layer on the support surface. The method described allows fixing125 I on supports with a low activity distribution on each activity-carrying support. [ABSTRACT FROM AUTHOR]- Published
