NCI: A radioactive isotope of iodine with an atomic mass of 131, a half life of eight days, and potential antineoplastic activity. Selectively accumulating in the thyroid gland, iodine I 131 emits beta and gamma particles, thereby killing thyroid cells and decreasing thyroid hormone production.,PDQ: A radioactive isotope of iodine with an atomic mass of 131, a half life of eight days, and potential antineoplastic activity.
