Radioactive iodine uptake testing is a useful diagnostic tool for assessing thyroid pathologies. The atom is the smallest unit of an element. An atom consists of electrons, protons and neutrons. Electrons revolve around the nucleus (made of protons and neutrons) in fixed orbits. The number of electrons equals number of protons in a neutral atom.
Radioactive iodine (commonly called radioiodine) is a form of iodine chemically identical to nonradioactive iodine. Therefore, the thyroid gland, which takes up iodine to make thyroid hormone, cannot distinguish between the two. However, the nucleus of a radioactive iodine molecule has excess energy and gives off radiation that can have effects on the cells in which it is concentrated.
