Potassium iodide for nuclear radiation: use, dosage, etc.
Potassium iodide is a salt composed of the minerals potassium (K) and iodine (I). Its chemical formula is “KI”.
Potassium iodide is a drug, and when used correctly can help protect the thyroid gland from radiation exposure caused by a nuclear emergency.
During a nuclear emergency, radioactive iodine can be released into the air. Radioactive iodine can negatively affect your thyroid and increase the risk of thyroid problems, including cancer.
Potassium iodide contains non-radioactive iodine, which can reduce the risk of thyroid damage. However, you should only take it for emergencies, not as a daily supplement.
Read on to find out how potassium iodide works, who should use it, and when you may need to use it.
Potassium iodide protects the thyroid by blocking the absorption of radioactive iodine. This is called iodine thyroid blockade.
When you take potassium iodide, your thyroid becomes saturated with non-radioactive iodine. This causes your thyroid to “fill up”.
As a result, your thyroid will not be able to absorb any type of iodine for the next 24 hours. Excess iodine, non-radioactive or radioactive, will leave your body through urine. This may help reduce the risk of thyroid cancer from radioactive iodine.
It is important to note that potassium iodide only protects your thyroid. It does not protect the rest of your body because it is not a general radioprotective agent, according to the
Additionally, potassium iodide does not protect against exposure to external radiation or other radioactive compounds.
Potassium iodide is used in nuclear emergencies. You should only take it when public health officials specifically tell you to.
To protect your thyroid, you need to take potassium iodide within a certain time frame. According to
The risk is higher in children and infants. Therefore, children and infants will likely need to take potassium iodide. It is safe for these age groups when taken at the correct dose.
In an emergency, public health officials will determine which age groups should take the drug.
When taking potassium iodide, it is crucial to take the exact recommended dose. According to
- Infants 1 month and under: 16 milligrams (mg)
- Children over 1 month and up to 3 years: 32mg
- Children over 3 years old and up to 12 years old: 65mg
- Teenagers over 12 and up to 18: 65mg
- Adults 18 and over: 130mg
- Pregnant or breastfeeding people: 130mg
You should never take potassium iodide more often than prescribed. It will not provide additional protection. Taking too much potassium iodide can lead to serious illness or death.
Potassium iodide is not an “anti-radiation” supplement. You should never use it as a preventative measure against radiation exposure. You should only use it during or after an anticipated exposure and only if instructed to do so by public health officials.
Potassium iodide will only work if you take it at the right time and in the right dose. Taking it continuously when there is no risk of radiation exposure can lead to serious complications.
In some situations outside of nuclear emergencies, healthcare professionals may prescribe potassium iodide for conditions such as severe hyperthyroidism and inflammatory skin dermatoses or to protect the thyroid when using radiopharmaceuticals.
People with low iodine intake can also use it as
When taken correctly, potassium iodide is unlikely to cause side effects. The benefits of protecting the thyroid during nuclear exposure outweigh the potential risks.
If side effects occur, they may include:
- mild allergic reaction
- itchy skin
- stomach ache
- swollen salivary glands
- metallic taste in the mouth
- burning sensation in the mouth and throat
- pain in the teeth and gums
Potassium iodide is available without a prescription. You can order it from online retailers that specialize in emergency preparedness supplies.
In the event of a nuclear emergency, your local health authorities will distribute potassium iodide to the community. You can also find potassium iodide at:
- fire and police stations
- evacuation centers
- town halls or town halls
Your local news channels and radio stations will tell you where you can get it if needed.
Again, only take potassium iodide if you have been exposed to radiation and have been specifically told to take it by healthcare professionals.
Potassium iodide is a drug that can help protect your thyroid during radiation emergencies. It contains non-radioactive iodide, which your thyroid absorbs. This prevents the absorption of radioactive iodine, potentially reducing the risk of thyroid cancer.
it is important to only take potassium iodide as instructed by local health authorities and only at the recommended dose. Potassium iodide is not a daily supplement and will not provide additional protection if taken more frequently.
If you have any questions or concerns about potassium iodide, consult a healthcare practitioner. They can provide personalized advice for you and your family.
