iodine
Radioactive elements are not used in the treatment of AIDS.
cobalt
The hard magnetic metal used in the production of steel is usually iron, which can be magnetized to produce permanent magnets. The radioactive form of the element used in cancer treatment is typically cobalt-60, which emits gamma rays that can be focused on a tumor to destroy cancer cells.
Treatment for simple goiter, which is an enlargement of the thyroid gland without associated thyroid dysfunction, typically includes iodine supplementation if the goiter is due to iodine deficiency. In some cases, monitoring the goiter may be sufficient if there are no symptoms or complications. If the goiter is large or causing symptoms, surgical removal may be considered. Hormonal therapy with levothyroxine may also be used to shrink the goiter in certain cases.

Uranium
The name for the time required for half of a radioactive element to decay into a stable element is called the half-life. It is a constant value unique to each radioactive isotope, and it is used to measure the rate of radioactive decay.
