Radioactive Iodine (RAI)

Radioactive iodine (I-131) has been used for decades to help treat selected thyroid cancer patients after surgery, although it can be used less commonly to treatment hyperthyroidism, or Graves' disease.

Taken in a pill form, RAI may require a short hospital stay to allow your body to clear it safely before you are able to go home.  RAI works by absoption into the body after the pill is swallowed.  Iodine-131 travels through the blood.  Thyroid cells are almost the only cells to take up the iodine, which is why systemic radiation treatment is possible without many side effects on the rest of the body.

Currently Radiation Oncology Associates offers RAI in New Hampshire at the following locations:


Dover , Lowell , Manchester
