About nuclear radiation and statement of cancer relation of thyroid gland
Chinese Medical Association's endocrine credit is known

Fukushima nuclear power station that Japan's heavy earthquake initiates reveals the incident and receives our country's public high concern, " the core is panic " Spread in some domestic areas for a time. As the special society engaged in clinic of thyroid gland and research of our country, we issued the following statements, clarify the relation of nuclear radiation and thyroid gland cancer.
First, environment of our country have not been influenced by the fact that revealed on the Japanese core yet
According to the announcement of State Bureau of Nuclear Safety of our country at 16 on March 17, the environment of our country has not been influenced by the fact that core of this Fukushima of Japan has been revealed yet, the monitoring data in every province are within the level of this bottom of nuclear radiation of this area, without any rising, so the public needn't be panic.

Second, impact on cancer incidence of thyroid gland of nuclear radiation
Nuclear radiation mainly includes three kinds of rays of . Among them, ray is that helium is nuclear, ray is an electron, ray is an electromagnetic wave with long shortwave. and ray penetrate force to be weaker, an ordinary brick can stop ray effectively, and a piece of paper can block ray. So, the ray that these two kinds of function are with nearer distance only prevents its radiant from entering body, influence will not be too big.

131 iodine is that core of this Fukushima revealed one of the main nuclide, its radiation type is ray. The iodine is that the thyroid gland makes one of the main raw materials of hormone of thyroid gland. A unique function of the thyroid gland can absorb the iodine voluntarily, make the iodine density in the thyroid gland reach several dozen times of the blood. Cut Pele's nuclear accident materials report of the promise according to the Soviet Union, pollute the morbidity of thyroid gland cancer of children in the area and increase notably, reach more than 200 times under the normal environment. So after core of this Fukushima was revealed and happened, Japanese Government has thrown in KI to the residents in the contaminated area in time. Its principle does not have radioactive iodine to occupy the thyroid gland gland to make, make 131 iodine revealed in nuclear power station unable to enter thyroid gland. But the iodine prevented from taking is ultra and heavy dose of, the administration amount that the adult recommends is 100 milligrams, to pregnant woman and children 3- 12 years old, the taking amount is 50 milligrams, the taking amount of children under the age of 3 is 25 milligrams.

Three, excessive has frauds to have no profit to take iodized salt
The iodine density in iodized salt is 30 milligrams / kilogram at present in our country. If achieve the goal of preventing the radioactive iodine from entering thyroid gland, the adult needs once to take more than 3 kilograms of iodized salt, this is not obviously practical. The normal adult's rational and safe intaking amount of iodine is 0.15- 0.3 milligrams per day (equivalent to 5- 10 grams of iodized salt every day) . Excessive may bring out first overbearing first making a reduction of and one's own immune thyroiditis aggravating to take in iodized salt, also will bring out thyroid gland papilla cancer. Excessive to take in the intersection of iodination and sodium, will bring out and aggravate hypertension, impel the intersection of heart and the intersection of brain and vascular emergence of disease also. So excessive to take iodized salt to prevent useless nuclear radiation, can endanger own health while being opposite.

From our country to over thousands of kilometers of Fukushima of Japan, not in the area of the nuclear pollution. The main pollution circulation way is the pollution of the atmosphere. National environmental nuclear radiation index about monitoring our country closely in the department. The public mustn't believe hearsay, in case that cause the injury to one's own health.
