Abstract

Abstract:

Iodine-125 seed is widely used in brachytherapy of intraocular tumors, brain tumors, and prostate cancer. The 125I seed is prepared by depositing 125I on a silver rod. This work was aimed at investigating effects of different parameters on the iodine adsorption, so as to optimize the process for preparing 125I core of the seed. The parameters investigated include kind and concentration of halogenation reagent, halogenation time, adsorption time, pH and carrier iodine quantity.

Key words: 125I, Adsorption, Seed source
