KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine.
More than 1,100 micrograms of iodine a day for adults can be dangerous. It could cause thyroid problems and other issues. Iodine supplements can also cause: Upset stomach.

Iodine is essential for proper thyroid function. If you're exposed to significant radiation, your thyroid will absorb radioactive iodine (radioiodine) just as it would other forms of iodine. The radioiodine is eventually cleared from the body in urine.
Iodine is an essential mineral you must get from your diet. Interestingly, your thyroid gland needs it to produce thyroid hormones, which have many important responsibilities in your body ( 1 , 2). The recommended daily intake (RDI) of iodine is 150 mcg per day for most adults.
Iodine supplements usually aren't necessary if you live in the United States or in most developed countries. Some alternative medicine practitioners recommend iodine tablets or kelp supplements — which are high in iodine — for people with hypothyroidism. It is true that iodine deficiency can cause hypothyroidism.
Taking a large dose of iodine, in theory, will sate your body's hunger for the substance and prevent you from absorbing the iodine-131 once it arrives. But after Chernobyl, the most significant release of radioactive iodine ever, there was a spike in thyroid cancer in children in the affected area.
If a
radiation emergency occurs, you can take actions to
protect yourself, your loved ones and your pets: Get Inside, Stay Inside and Stay Tuned.
Stay Inside
- Close windows and doors.
- Take a shower or wipe exposed parts of your body with a damp cloth.
- Drink bottled water and eat food in sealed containers.
High iodine intakes can also cause thyroid gland inflammation and thyroid cancer. Getting a very large dose of iodine (several grams, for example) can cause burning of the mouth, throat, and stomach; fever; stomach pain; nausea; vomiting; diarrhea; weak pulse; and coma.
Both the zone and the former power plant are administered by the State Agency of Ukraine on Exclusion Zone Management. The three other reactors remained operational after the accident but were eventually shut down by 2000, although the plant remains in the process of decommissioning as of 2020.
KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine.
Your body will slowly eliminate the radioactive iodine through body fluids such as your saliva, sweat and urine. As this happens, things you touch or people that come near you will be exposed to radioactive iodine, which is unsafe. After taking the capsules, you will need to follow special instructions.
The foods highest in iodine include seaweed, dairy, tuna, shrimp and eggs. Additionally, most table salt has been iodized, providing an easy way to add iodine to your meals.
What is KI? Potassium iodide (KI) is the same form of iodine used to iodize table salt. KI floods the thyroid with iodine, thus preventing radioactive iodine from being absorbed.
Iodine (medical use) Iodine is used to treat and prevent iodine deficiency and as an antiseptic. For iodine deficiency it can be given by mouth or injection into a muscle. As an antiseptic it may be used on wounds that are wet or to disinfect the skin before surgery.
In August 1986—at the first international conference on the Chernobyl disaster—the IAEA established but did not make official a figure of 4,000 deaths as the total number of projected deaths caused by the accident over the long term.
The thyroid gland needs iodine to produce hormones that regulate the body's energy and metabolism. In babies and children, the thyroid gland is one of the most radiation-sensitive parts of the body. Most nuclear accidents release radioactive iodine into the atmosphere, which can be absorbed into the body.
Here are 10 signs and symptoms of an iodine deficiency.
- Swelling in the Neck. Share on Pinterest.
- Unexpected Weight Gain. Unexpected weight gain is another sign of an iodine deficiency.
- Fatigue and Weakness.
- Hair loss.
- Dry, Flaky Skin.
- Feeling Colder Than Usual.
- Changes in Heart Rate.
- Trouble Learning and Remembering.
Iodine is POSSIBLY UNSAFE when taken by mouth in high doses. Do not take more than 1100 mcg of iodine per day if you are over 18 years old; do not take more than 900 mcg of iodine per day if you are 14 to 18 years old. Higher intake has been shown to cause thyroid problems in the newborn in some cases.
Iodine can be absorbed through intact skin in time dependent manner.
Adding more iodine to your diet may help reverse the effects of a slow metabolism, as it can help your body make more thyroid hormones. Summary Low iodine levels may slow your metabolism and encourage food to be stored as fat, rather than be burned as energy. This may lead to weight gain.
Iodine is cleared from the circulation primarily by the thyroid and kidney. Under normal circumstances, plasma iodine has a half-life of approximately 10 hours, but this is shortened if the thyroid is overactive, as in iodine deficiency or hyperthyroidism.
medications for hyperthyroidism, as additional iodine can lead to hypothyroidism. warfarin and other blood thinners, as iodine may reduce their effectiveness. amiodarone, because taking iodine supplements with this drug can cause dangerously high levels of iodine in the body.
Although pink Himalayan salt may naturally contain some iodine, it most likely contains less iodine than iodized salt. Therefore, those who have iodine deficiency or are at risk of deficiency may need to source iodine elsewhere if using pink salt instead of table salt.
Iodine poisoning usually results from taking too many iodine supplements. It's very hard to get iodine poisoning from food alone. Remember, adults can tolerate up to 1,100 mcg a day. Taking a one-time dose of too much iodine usually won't cause iodine poisoning.
Is it safe to take KI tablets with an expired shelf-life? Yes, potassium iodide tablets are inherently stable and do not lose their effectiveness over time. Manufacturers must label their products with a shelf-life to ensure that consumers purchase safe and useful products.
Median time for urinary iodine level to normalize was 43 days, with 75% of subjects returning to baseline within 60 days, and 90% of subjects within 75 days.
Iodine-131 contamination from thyroid cancer patients. In eight patients treated with doses of 131I ranging from 3.7 to 14.8 GBq (100-400 mCi), activity levels were measured in room air, from room surfaces, the toilet, the patients' exhaled breath, skin, saliva and toothbrushes, and the gloves used by medical staff.
Although the treatments with 131-I are generally safe, RAI produces radiation so patients must do their best to avoid radiation exposure to others, particularly to pregnant women and young children. The amount of radiation exposure markedly decreases as the distance from the patient increases.
