Iodine-131, in a sodium iodide tablet, is used to measure the activity of the thyroid gland. If a tablet initially contains 120.0 mg of I-131, what is the mass of the nuclide that remains after 32 days? The half-life of I-131 is 8 days.

Iodine-131 is administered orally in the form of NaI(aq) as a treatment for thyroid cancer. The half-life of iodine-131 is 8.04 days. How much time is required for the activity of a sample of iodine-131 to fall to 17.5 percent of its original value? ____days Nitrogen-13 is used in tracers injected into the bloodstream for positron emission tomography (PET). The half-life of nitrogen-13 is 10.0 minutes. If you begin with 45.1 mg of this isotope, what mass remains after 27.2...
