Procedure Information:
Radioactive iodine (I-131) is used to treat an overactive thyroid gland or thyroid cancer. You may be weighed and measured to determine the dose of the I-131. You will be asked to drink the iodine or to take it in capsule form. The iodine is attracted to the thyroid gland.

The nuclear medicine technologist measures the amount of radiation around your body. Higher doses may require a hospital stay. You may be admitted to the hospital for 2-3 days, depending on the planned dose. If you stay in the hospital, you will have to remain in the room by yourself until the radiation level goes down. Your body fluids, including your urine, are radioactive for several days. This is because the I-131 is eliminated in urine. Please urinate directly into the toilet while sitting down and flush twice.

Staff will place a sign on the patient's door "Caution-Radioactive Materials". The nursing staff will enter your room for short periods of time only, such as to check on you and take your vital signs. Visitors are limited to about 15 minutes a day. Visitors should maintain a distance of three feet from the patient, unless otherwise instructed. No children under 18 years of age, and no pregnant visitors are allowed. When the radiation level goes down to a safe level, you will be discharged home.

Additional Information:
Waiting Room for family is located in the Radiology Department. Please inform the technologist if you are pregnant prior to the scan. You will be asked a series of questions regarding your medical history. You will be asked to sign a consent form prior to the procedure.
