Can iodine help to prevent radiation sickness?

Iodine can help to prevent radiation sickness by blocking the uptake of radioactive iodine by the thyroid gland. Radioactive iodine is a common product of nuclear reactions, and it can be harmful to the body if it is ingested or inhaled. The thyroid gland is a small, butterfly-shaped gland located in the front of the neck. It produces hormones that regulate metabolism. Radioactive iodine can damage the thyroid gland and lead to a condition called thyroid cancer.

Iodine supplements can help to prevent radiation sickness by saturating the thyroid gland with stable iodine. This prevents the thyroid gland from absorbing radioactive iodine. Iodine supplements should be taken before or during exposure to radiation, and they should be taken in the recommended dosage. Iodine supplements can have side effects, such as nausea, vomiting, and diarrhea. If you are pregnant or breastfeeding, you should talk to your doctor before taking iodine supplements.
