Prophylactic potassium iodide was first used, and to great success, during the Chernobyl disaster in Live Science. Live Science Staff. The lables I've read on the pill bottles say "daily value not established", and the pills are So what are people suppose to do, take 2 or 3 bottles of the pills to get the 2Kg you advise?
My research indicates you can take about a tablespoon of table salt per day to absorb the needed potassium iodide needed. You would have to take over 2Kg of salt per day to get the right quantity of KI from iodized salt - that would kill you. For people near a source of radioactive contamination, they MUST take the pills - there is absolutely no way to get a sufficient quantity of iodine from salt for radiation protection. Iodized salt is enough to prevent goiters in populations that don't have access to seafood, but it is not sufficient to protect against radiation poisoning.
Naturally you would have to use more iodized salt than normal Especially considering how inexpensive it actually is! Which will, in a pinch, fill the thyroid up with non-radioactive iodine, if taken in larger than usual amounts , when potassium iodide pills are not available.
I believe people should know this, so if the producers of potassium iodide pills or liquids run short, or if suppliers start gouging the public, folks are aware of simple solutions readily available. In the United States, most people who reside within 10 miles of a nuclear power plant are given potassium iodide pills to store.
I hope the situation in Japan calms down very soon - children and adolescents are at the most risk from the radiation. It just breaks my heart. This Hub is certainly interesting in light of the tragedy in Japan. I am filing it in the memory banks for future reference. For people exposed to radiation danger, the concentration of sodium iodide in iodized salt would not be sufficient to ward off the dangers of radioactive iodine released from a nuclear power plant meltdown.
For people in a danger area, the sodium iodide tablets are necessary, but people outside the danger area shouldn't take them. Iodized salt does prevent goiters in people who lack access to seafood or other natural iodine sources the thyroid needs some iodine to function normally.
Iodizing salt is a nutrition supplement, not an alternative to preventing disease from exposure to radiation. This is very good information, but as you mentioned, potassium iodide is in common table salt, so the same or near the same benefits can be found with using iodized table salt.

Additionally, the more exposure to the thyroid from radioactive iodine, the higher the chance of thyroid cancer and benign thyroid nodules. The risk of hypothyroidism and thyroid cancer is higher for children who are still growing, than for adults. Potassium iodide pills are pills containing non-radioactive iodine. By taking the correct dose of potassium iodide right before or during exposure to airborne radioactive iodine, a large amount of stable iodine enters the body and reduces or blocks the amount of radioactive iodine that is taken into the thyroid.
This has been shown to be quite effective. By reducing the amount of the radioactive iodine in the thyroid, the radiation dose to the thyroid is reduced, resulting in a smaller risk of health effects. Short-term administration of potassium iodide at thyroid blocking doses is quite safe for the general population who have regular thyroid function.
In Poland, after the Chernobyl incident, single-dose stable iodine pills were given to 10 million children and no serious side effects were seen. Some minor side effects were noted including gastrointestinal upset and minor rashes. Persons who have a known allergy to iodine or thyroid disorders e.
For others with normal thyroid function, taking a short-term dose of potassium iodide for thyroid protection during a nuclear emergency involving the emission of radioactive iodine, is considered safe and should not have any major health consequence. Adults older than 40 years should not take KI potassium iodide unless public health or emergency management officials say that contamination with a very large dose of radioactive iodine is expected.
The FDA has approved two different forms of KI potassium iodide , tablets and liquid, that people can take by mouth after a radiation emergency involving radioactive iodine.
Tablets come in two strengths, milligram mg and 65 mg. The tablets have lines on them so that they may be cut into smaller pieces for lower doses. According to the FDA, the following doses are appropriate to take after internal contamination with or likely internal contamination with radioactive iodine:. Taking a stronger dose of KI potassium iodide , or taking KI more often than recommended, does not offer more protection and can cause severe illness or death.
A single dose of KI potassium iodide protects the thyroid gland for 24 hours. A one-time dose at recommended levels is usually all that is needed to protect the thyroid gland. In some cases, people can be exposed to radioactive iodine for more than 24 hours. If that happens, public health or emergency management officials may tell you to take one dose of KI potassium iodide every 24 hours for a few days. Avoid repeat dosing with KI potassium iodide for pregnant and breastfeeding women and newborn infants.
Side effects of KI potassium iodide may include stomach or gastro-intestinal upset, allergic reactions, rashes, and inflammation of the salivary glands.
When taken as recommended, KI potassium iodide can cause rare adverse health effects related to the thyroid gland. Newborn infants less than 1 month old who receive more than one dose of KI potassium iodide are at risk for developing a condition known as hypothyroidism thyroid hormone levels that are too low. If not treated, hypothyroidism can cause brain damage.
KI potassium iodide is available without a prescription.
