The war in Ukraine has heightened fears about nuclear exposure and interest in iodine pills that can help protect the body from some radiation.
About Iodine tablets:
- Potassium iodide, or KI, offers specific protection against one kind exposure. It prevents the thyroid — a hormone-producing gland in the neck — from picking up radioactive iodine, which can be released into the atmosphere in a nuclear accident.
- Iodine tablets work by filling up the thyroid with a stable version of iodine so that the radioactive kind can’t get in.
- If the thyroid is already packed with potassium iodide, it won’t be able to pick up the harmful iodine that’s left after a nuclear accident.
- But potassium iodide doesn’t protect against other kinds of radioactive threats. A nuclear bomb, for example, can release many different kinds of radiation and radioactive material that can harm many parts of the body.
