Iodine I131: effects on health and prevention with Iodine tablets

The video discusses the impact of Iodine 131 on the thyroid, which can lead to thyroid cancer. Iodine tablets can protect the thyroid by saturating it with benign iodine, preventing radioactive iodine from being absorbed.

Symptoms of excess iodine include skin rashes, headaches, and more severe conditions like hyperthyroidism. Pregnant women should be cautious as excess iodine can affect the fetus.
