Purpose: Iodine-131 is used as a radiopharmaceutical to treat thyroid cancer. The current study aimed to evaluate the effects of vitamins E and C on the level of DNA double-strand breaks (DSBs) caused by Radioiodine-131 (I-131) in human lymphocytes. Materials and Methods: Whole blood samples from human volunteers were incubated with a certain concentration of vitamins. After 1-h incubation, the samples were incubated with 20 μCi I-131/2 mL (blood + NaCl) for 1 h. To evaluate the effects of antioxidants, lymphocytes were separated, and the mean DSBs/cell was measured for each sample through γ-H2AX assay. Results: After 1-h incubation with 20 μCi I-131/2 mL (blood + NaCl), iodine-131 increased the level of DSBs by 102.9%, compared with the background group. Vitamins E and C reduced the level of DSBs by 21.5% and 36.4%, respectively. Conclusion: Using vitamins E and C as antioxidants can reduce the toxicity of I-131. Furthermore, vitamin C provided the more protection for DNA, compared with vitamin E.
