摘要：
Background: One of the key techniques for the preparation of I-125 seeds is adsorption of I-125 onto silver bits coated by palladium (pd). Carriers played an important role in the adsorption of I-125 on palladium. KI is used as a carrier for fixing of I-125 onto silver wire bits coated with palladium. Materials and Methods: Three procedures KI, KOH, NH4OH were investigated for adsorption of I-125 activity by different carriers. Results: Adsorptions percentage of I-125 on treated silver beads showed about 85% by using KI as a carrier, the KOH showed 74% and 65% for NH4OH. Conclusion: The results indicated that, the use of KI as a carrier was suitable for adsorption of I-125 on treated silver seeds with Pd than KOH and NH4OH. Iran. J. Radiat. Res., 2012; 10(2): 105-107
