None.: The amount of tc99m or iodine given is a small dose and does not pose a health risk for a radioactive thyroid scan.

Always a risk: Your body/thyroid will recieve a tiny quantity of radiation exposure. Thats the risk. Have your md explain why he/she wants the test.

Thyroid scan: I assume you are referring to a nuclear thyroid scan and uptake which is usually performed for thyroid nodule and or hyperthyroidism assessment. You will be given a capsule (orally) of radioactive iodine (I-123) which has a very minimal dose of radiation, usually around 200 microcuries and you will not feel any side effects.
