When you take potassium iodide, your thyroid gland absorbs it. If you get the right amount at the right time, it will saturate your thyroid gland. This can help block any inhaled or ingested radioactive iodine from being absorbed by your thyroid. This lowers your risk for radiation damage to that gland.
Infants and young children. Newborns and children are most at risk for a thyroid injury from radioactive iodine. Those with low amount of iodine in their thyroid are also likely to have thyroid damage.
If there is a radiation emergency at a nuclear plant, large amounts of something called radioiodine could be put into the air. This could hurt your thyroid gland, or even cause thyroid cancer later on. You could breathe in the radioiodine or eat food that has some radioiodine in it. When you take the KI pill, it protects your thyroid gland from being harmed.
KI will only protect you from radioactive iodine. It does not protect you from other kinds of radioactive material. KI works very well to protect your thyroid gland. However, it protects only your thyroid, not other parts of your body.
The table below shows the smallest KI dose that different age groups can take which will protect the thyroid. KI comes in liquid, 65-mg tablets and 130-mg tablets. Since it is hard to cut many pills, the State Health Commissioner says that, in an emergency, it is safe for children at school or day care centers to take the whole pill. It's better for children under 12 years old to take the 65-mg pill, but it is safe to take the 130-mg pill if that is the only one you have. For children or babies who cannot take pills, parents and caregivers can cut or crush the pill to make lower doses, or give the liquid form of KI.
The tablets work by saturating the thyroid with iodine for 24 hours, blocking the intake of highly radioactive iodine-131 that would otherwise be readily absorbed by the organ through contaminated air, food, or water.
Moreover, iodine is not a silver bullet solution for protecting oneself in a fallout. It cannot help against the threat of other common radioactive elements emitted in a blast, such as cesium-137 or strontium-90.
Potassium iodide is a salt, similar to table salt. Its chemical symbol is KI. It is routinely added to table salt to make it \"iodized.\" Potassium iodide, if taken in time and at the appropriate dosage, blocks the thyroid gland's uptake of radioactive iodine and thus could reduce the risk of thyroid cancers and other diseases that might otherwise be caused by exposure to radioactive iodine that could be dispersed in a severe nuclear accident.
Potassium iodide is a special kind of protective measure in that it offers very specialized protection. Potassium iodide protects the thyroid gland against internal uptake of radioiodines that may be released in the unlikely event of a nuclear reactor accident.
When potassium iodide is ingested, it is taken up by the thyroid gland. In the proper dosage, and taken at the appropriate time, it will effectively saturate the thyroid gland in such a way that inhaled or ingested radioactive iodines will not be accumulated in the thyroid gland. The risk of thyroid effects is reduced. Such thyroid effects resulting from radioiodine uptakes due to inhalation or ingestion, or both, could result in acute, chronic, and delayed effects. Acute effects from high doses include thyroiditis, while chronic and delayed effects include hypothyroidism, thyroid nodules, and thyroid cancer.
The population closest (within the 10 mile EPZ) to the nuclear power plant are at greatest risk of exposure to radiation and radioactive materials. The purpose of radiological emergency preparedness is to protect people from the effects of radiation exposure after an accident at a nuclear power plant. Evacuation is the most effective protective measure in the event of a radiological emergency because it protects the whole body (including the thyroid gland and other organs) from all radionuclides and all exposure pathways. However, in situations when evacuation is not feasible, in-place sheltering is substituted as an effective protective action. In addition, administering potassium iodide is a reasonable, prudent, and inexpensive supplement to both evacuation and sheltering. When the population is evacuated out of the area, and potentially contaminated foodstuffs are interdicted, the risk from further radioactive iodine exposure to the thyroid gland is essentially eliminated.
If terrorists attack either at a nuclear power plant or with a \"dirty\" bomb, radioactive iodine would have to be released in order for potassium iodide (KI) to be needed. Potassium iodide protects the thyroid gland only against the internal uptake of radioiodines.
A nuclear power plant will make protective action recommendations based on current emergency plans, which may include the recommendation to take KI as a supplement to evacuation and/or sheltering. In the case of a dirty bomb, protective actions will be made according to the threat presented. If the bomb contained radioactive iodine, then the use of KI may be appropriate. However, radioactive iodine is not considered to be a viable component of a dirty bomb due to its relatively short half-life and the difficulties in obtaining significant quantities. More information on dirty bombs and response to terrorist activities can be found on the Nuclear Security and Safeguards Web page. Other information can be found at the Department of Homeland Security.
For States interested in extending the shelf life of KI, the FDA has published guidance on shelf life extension for the tablet form of potassium iodide. Extending the shelf life of KI tablets is possible due to the inherent stability of the chemical form. However, the tablets must be stored under the conditions specified by the manufacturer to be considered for shelf life extension. In addition, this guidance only is intended for Federal agencies and State and local governments that maintain KI stockpiles under the conditions specified by the manufacturer.
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.
According to FDA guidance on Shelf-life Extension, studies over many years have confirmed that none of the components of KI tablets, including the active ingredient, has any significant potential for chemical degradation or interaction with other components or with components of the container closure system when stored according to labeled directions. To date, the only observed changes during stability (shelf-life) testing have been the failure of some batches of KI tablets to meet dissolution specifications. Some tablets tested required slightly longer than the specified time to achieve dissolution. Even in the case of a failure of this sort, the product remains usable. In such cases, instructions can be provided to crush the tablets and mix them with a juice or other liquid prior to administration as suggested for emergency pediatric dosing.
Stockpiling of potassium iodide (KI) is highly recommended by health officials worldwide to prevent thyroid cancer of those exposed to radioactive iodine. Radioactive iodine is the predominant radioisotope released from a nuclear reactor accident or detonation of a nuclear weapon (due to nuclear fission) and can travel thousands of miles downwind.
It is particularly important that children and adolescents under 18 years of age and pregnant and breast-feeding women take the tablets because they are at greatest risk of contracting thyroid cancer after being exposed to radioactive iodine.
In the event of a nuclear accident, radioactive iodine can be dispersed in the air and absorbed by the thyroid gland when inhaling contaminated air and/or ingesting contaminated food and drinks. Iodine tablets will block the absorption of radioactive iodine by the thyroid gland and reduce the risk of you contracting cancer of the thyroid gland.
In special circumstances, it may also be appropriate for adults aged 18 to 40 to take the tablets. People over 40 are at very little risk of contracting thyroid cancer and do not need to take iodine tablets. Anyone who has had their thyroid gland removed need not take iodine tablets either.
NB! Do not confuse Iodine tablets for use in the event of a nuclear accident (Jodix) must not be confused with dietary supplements containing iodine. Ask your pharmacist for advice if you need daily dietary supplements which contain iodine, e.g. during pregnancy.
In the updated guidelines based on WHO guidelines from 2017, the ministry recommends households with members aged 3-40 acquire iodine tablets as secondary precautions for their homes. [EPA/HANNIBAL HANSCHKE]
An accident at a nuclear power plant, like the Zaporizhzhia nuclear station currently under Russian control in southeastern Ukraine, would release radioactive iodine into the environment, which could build up in the thyroid gland, experts warn.
To disinfect water with iodine, you need liquid iodine (2%) or iodine tablets. If you use tablets, follow the directions on the package. If you use liquid iodine, follow the directions listed below. You can buy iodine at most drugstores and some outdoor supply or camping stores.
Potassium iodide (KI) can be used to protect the thyroid gland from radioactive iodine that may be released into the air in the unlikely event of a radiological emergency. In very small quantities, it is an essential nutrient for your thyroid gland to function properly. In the event of a nuclear emergency, KI is effective in reducing the threat of thyroid cancer to residents at risk of inhaling or ingesting radioactive iodine. It comes in easy to swallow tablet form. 781b155fdc
