Potassium iodide pills prevent against radiation poisoning, particularly of the thyroid gland. Radiation leaking from damaged nuclear plants in Japan poses risk to those who are in the proximity. In Thailand, the authorities said they will be distributing medicine to citizens traveling to Japan for free, in order to protect them against radiation.
Potassium iodide protects the thyroid gland against thyroid cancer by preventing the absorption of iodine, which is highly radioactive. Thyroid cancer puts children at most risk. Although Japan’s Nuclear Safety Agency has stored potassium iodide to give out to its citizen in an emergency, supplies are now getting short.
The common symptom of thyroid cancer is a nodule near the base of the neck. Later in symptoms could cause pain in neck and changes in voice.
In 1982, FDA approved potassium iodide to protect thyroid glands from radioactive iodide. In an accident at a nuclear power plant or nuclear bomb fallout, its radionuclides can particularly dangerous to thyroid glands. Saturating one’s body with a iodide prior to exposure can prevent radioiodine uptake. Potassium iodide should be dosed on daily basis, until a danger of exposure to radioiodines no longer exists.
It is recommended to take potassium iodide pills as a necessary precaution to prevent any risk related to radiation poisoning.
