A method of producing an iodine seed, the method comprising: forming an intermediate by introducing a type of anions selected from a group consisting of phosphates, oxalate wherein the oxalate anion is formed from sodium oxalate (Na 2 CO 2 O 4) and arsenates into a surface of a support (step 1), and substituting the anions of the intermediate of step 1 with I 125 (step 2), forming the intermediate in step 1 by introducing a support into a solution in which one type of anions selected from a group consisting of phosphates, oxalate wherein the oxalate anion is formed from sodium oxalate (Na 2 CO 2 O 4) and arsenates, and stirring is performed, and wherein substituting the anions of the intermediate with I 125 in step 2, by introducing the intermediate into an I 125 solution and stirring, and wherein the support is from a group is selected from silver (Ag), silver-containing ceramics and silver-treated heavy metal surface. |
