I suspect that what you’ve read is that RAI is successful in dealing with the hyperthyroidism, as opposed to bringing about remission from Graves’. The goal these days with RAI is to completely knock out all thyroid hormone production, so you *aren’t* likely to have a recurrence of hyperthyroidism. All three treatment options have risks and benefits.
