The radioactive iodine in involving nuclear and radiological emergency early and mid likely ingested the radioactive iodine and thick collection in the ministry of anterior portion within thyroid, make this the organ is large doses of radiation; At this time, taking stable iodine is reduced to inhaled or eating thyroid absorbed the radioactive iodine an effective preventive measures. If in the intake of radioactive material containing radioactive iodine six hours before taking stable iodine, is almost completely blocked radioactive iodine in the deposition within thyroid. If inhaled radioactive iodine in at the same time, it can take stable iodine in blocking 90% of the radioactive iodine within thyroid deposition. The measures of effectiveness of implementation of time with the delay in inhaled decrease, but within hours of radioactive iodine stable iodine, still can use to the amount of radioactive iodine thyroid absorbed by half or so.
Taking stable iodine is generally not the sole use of a kind of protective measures, it often and concealment measures, evacuated simultaneously. Recommended for adults to low doses of 100 mggood blog for everything of iodine (equivalent to 130 mg potassium or 170 mg iodate.at the potassium); 3 ~ 12 for pregnant women and children aged 50 mg; instead of taking 3 children under the age of 25 milligrams sulfate. The above recommended by iodine volume the risk is not big, serve only a handful of people may appear any allergies.
Some groups, such as for pregnant women, infants, children and teenagers under 16 should be stable iodine in taking notice. Others, such as thyroid nodule, prominent eyes who have sex in the thyroid gland has no cure, has received the healer radioactive iodine, thyroid diseases such as chronic inflammation of the patients, thyroid unilateral resection,say subclinical thyroid function, low person of iodine allergy and some skin disease patients, should be careful with or without stable iodine.
