Patient:

Doctor Chen: Hello! I am asking about and many friends will search the Internet, friends say it is best to ask a doctor Chen, you are specialists in nuclear medicine, mastered it, and very have a reputation. I'm sure you will help me helpless us. Don't refuse us?

The recent Japanese nuclear leak on the newspaper "the nuclear leakage occurred, what should we do? A text. The article said, "in order to alleviate the damage of radioactive elements on the body (such as to prevent the absorption of radioactive iodine 131), can take some stable tablets". Can not help but ask:

1, we have to suffer from thyroid disease (especially CA patients) and best eat or not eat iodine patients, if the nuclear leakage affects China, when Chinese authorities put iodine to my hands, I should eat or not to eat? Can I eat like this?. I want to, then you may find it, in any case can not contact you, find you consult too many people.

2, when the patient's thyroid double cut, once there is a transfer of iodine to the use of the so-called "clear a", but the article said, iodine 131 once inhaled by the human body, may lead to thyroid disease". The contradiction between the two? Does the doctor treatment using the poison?

3, I also have one thing is unknown, we are here to the doctor said I am not only limited to iodine iodine iodine areas? Is it true that all patients with thyroid disease?

Department of nuclear medicine, Shanghai No.6 People's Hospital, Chen Libo:

Your question has certain representativeness, the reply is as follows:

1 the harm of nuclear radiation depends on the type and dose of radiation, and the mode of irradiation (external and internal). On the one hand, the radionuclide release of Japan's nuclear accident is mainly -131 iodine and cesium -137, if the former through channels such as the human diet, skin absorption will occur in radiation damage to the thyroid, primarily to hypothyroidism and thyroid cancer (mainly papillary carcinoma) the incidence rate may rise. In this case, we will use the stable iodine to block the thyroid gland in the lower radiation dose to block the thyroid uptake of radioactive iodine -131, thereby reducing the harm. In order to protect the thyroid nuclear radiation crisis, the recent American Thyroid Association (ATA) published a comment that people underestimate the importance of potassium iodide distribution in the nuclear crisis area. On the other hand, due to the sensitivity of thyroid external exposure, under special circumstances, it may be possible to take large doses of iodine -131 to destroy the thyroid gland, reduce the incidence of thyroid cancer. It is not difficult to see that iodine -131 can also prevent disease.

2 at present, the situation is far from being in the country, do not panic too much, please focus on the mainstream media tracking reports.

3 different from radioactive iodine -131, stable iodine plays an important role in the synthesis of thyroid hormone, the amount of stable iodine intake, the normal maintenance of human thyroid function is very important. Like you such patients with thyroid cancer after surgery, if there is no arrangement of iodine -131 treatment, diet is not avoid iodine requirements, there is no need to encourage the iodine content of food to eat, because you need thyroxine is exogenous (thyroxine).

4 in your case, the patient is usually not necessary to worry about the thyroid gland because it has not been removed.

5 it is good for you to make a full and accurate evaluation and follow up follow-up plan for you.
