SUMMARY
Radioactive iodine, specifically iodine-131 (I-131), is administered to patients to reduce thyroid growth and activity. I-131 has a half-life of 7.56 days, which is a measure of its radioactivity. However, the radiation levels in the human body can decrease at a faster rate than this calculated half-life due to the biological half-life, which reflects the body's ability to excrete the substance. Understanding the distinction between the physical half-life and biological half-life is crucial for comprehending the effects of radioactive iodine on thyroid function.
