你的医生会给你这样一个注意事项。

You will be able to return home following radioactive iodine treatment, but you should avoid prolonged, close contact with other people for several days, particularly pregnant women and small children. Nearly all the radioactive iodine leaves the body during the first two days following the treatment, primarily through the urine. Small amounts will also be excreted in saliva, sweat, tears, vaginal secretions, and feces.

If your work or daily activities involve prolonged contact with small children or pregnant women, you will want to wait several days after your treatment to resume these activities. Patients with infants at home should arrange for care to be provided by another person for the first several days after treatment. Your radiologist can be more specific for your given situation, but usually this time period is only two to four days.

Your treatment team will give you a list of other precautions to take following your treatment with I-131. The following guidelines comply with the Nuclear Regulatory Commission:

1） Use private toilet facilities, if possible, and flush twice after each use.
2） Bathe daily and wash hands frequently.
3） Drink a normal amount of fluids.
4） Use disposable eating utensils or wash your utensils separately from others.
5） Sleep alone and avoid prolonged intimate contact. Brief periods of close contact, such as handshaking and hugging, are permitted.
6） Launder your linens, towels, and clothes daily at home, separately. No special cleaning of the washing machine is required between loads.
7） Do not prepare food for others that requires prolonged handling with bare hands.
8） If you breast-feed, you must stop.
9） You should avoid becoming pregnant for about one year after treatment.
You must be sure you are not pregnant before receiving I-131. Many facilities require a pregnancy test within 24 hours prior to giving I-131 in all women of child-bearing age who have not had a surgical procedure to prevent pregnancy.
