Radiation can come in the form of a pill. Iodine (131 I) used in thyroid treatment might be given in pill form or as a liquid. The choice is an institutional decision based on many factors, including the amount to be given to a patient.
Radioactive iodine increases the risk of thyroid cancer. It takes years before the disease develops. Especially young people, children and unborn babies are at risk: their thyroid is the most sensitive to radioactive iodine. Fortunately there is a solution: by taking extra iodine in the form of iodine pills, the thyroid becomes saturated. There is no place in the body to store radioactive iodine. What are iodine pills used for? Iodine tablets are intended primarily for young people who live near a nuclear power plant. Within a radius of 100 kilometers, the government holds iodine tablets available for the groups at risk.
